Description

Technical Field

[0001] The present invention relates to a tattoo printing method, an ink fixing agent composition for tattoo printing, an ink composition for tattoo printing, a fixer composition for tattoo printing, and a tattoo printing kit containing the same.

Background Art

[0002] As part of self-expression, many people are interested in clothing, hair, accessories, etc., and express their individuality by putting designs on their own skin. Generally, methods of drawing images on the skin include face painting, makeup, water transfer stickers, instant stickers, tattoo stencils, painting, natural dyeing, henna, tattoos, etc. General tattoos, henna, or body painting, etc. require treatment by a person with specialized skills, so they are not easily accessible, and stickers, tattoo stencils, etc. have the problem that only limited designs can be used. Therefore, there is an increasing interest in a skin printer that allows users to easily output a desired image onto the skin.

[0003] On the other hand, the inkjet recording method is a method of transmitting a document or image in digital data format as an electrical signal, and spraying fine ink droplets of each color onto paper through a head to print on a medium. In the head, hundreds to thousands of fine ink ejection ports (nozzles) are arranged, and fine ink droplets of 1 to 10 picoliters (pl) are sprinkled at each arranged position. The inkjet recording method includes an electrostatic attraction method that uses electrostatic attraction to eject ink droplets, a pressure transfer method that uses a piezoelectric element or the like to apply mechanical vibration or displacement to the ink, and a thermal transfer method that generates bubbles by heating the ink and uses the pressure at that time to eject the ink.

[0004] For directly printing ink on the skin, harmless aqueous ink can mainly be used, and the aqueous ink contains 60 - 90% water. When the aqueous ink is printed on a medium and collides, it dries while evaporation, penetration, and diffusion proceed simultaneously. That is, the pigment of the ink remains on the medium, and the water either penetrates into the medium or evaporates and dries. At this time, how the aqueous ink dries and whether it is fixed at the location where the pigment has dropped will act as a major influence on the printing quality.

[0005] Generally, the pigment in the aqueous ink does not stay on the surface of the medium but penetrates and is fixed inside for printing. Therefore, if the penetration of the pigment's water into the printing medium is slow, the ink may seep on the medium surface, resulting in ink color contamination. To achieve ideal printing quality, the colorants (dyes or pigments) present in the aqueous ink need to remain in a circular form on the surface in large quantities to exhibit bright colors, and the water needs to be dried quickly to prevent the aqueous ink from moving in the planar direction.

[0006] In office paper or inkjet - dedicated paper, vertical adsorption of aqueous ink occurs quickly. However, the skin is smooth, has a non - uniform surface, and has poor interaction with aqueous ink. Therefore, on the skin, the penetration of aqueous ink does not occur smoothly and requires more time to penetrate the skin than to penetrate ordinary paper. Also, on the skin, the drying time of glycol and diol, which are the main solvents of aqueous ink, is long, and they have poor spreading characteristics.

[0007] Therefore, there is an increasing need to develop inks, fixatives (primers), or fixers (topcoats) that treat the skin before or after printing to accelerate the skin adsorption rate and drying rate of aqueous ink, so that the ink is printed without seeping and excellent printing quality is achieved.

That is, all combinations of various elements disclosed in the present application belong to the scope of the present invention. Also, the scope of the present invention is not limited by the specific descriptions described below.

[0081] Furthermore, those with ordinary skill in the art can recognize or confirm a number of equivalents to the specific embodiments of the present invention described in this application using only ordinary experiments. Such equivalents are intended to be included in the present invention.

[0082] In this specification, a skin printing device (tattoo printing device) includes, for example, a skin printer (tattoo printer) for printing an ink composition on the skin. The skin printing device is for printing a specific image on the skin using an ink composed of cosmetic raw materials that can be used on the skin, and can print a clear image on the skin while keeping the distance between the skin and the nozzle constant, but the invention of the present application is not limited thereto. Also, in this specification, the skin printing device is for printing ink on a medium such as paper or film or on the skin, and is not limited to the type of the device.

[0083] In this specification, terms such as "tattoo print, tattoo printer, tattoo printing device" and "skin print, skin printer, skin printing device" can be used for printing ink on the skin, and include a device for printing ink on a medium such as paper, or a device for printing ink on a medium such as paper and then printing on the skin using the medium. The terms "skin print, skin printer, skin printing device" have the same meaning as the terms "tattoo print, tattoo printer, tattoo printing device" respectively, and can be used interchangeably in this specification.

[0084] In this specification, terms such as "ink, fixer, ink fixing agent" can respectively have the same meaning as "ink composition, fixer composition, ink fixing agent composition", and can be used interchangeably in this specification. Also, "ink composition, fixer composition, ink fixing agent composition" can have the same meaning as "ink composition for tattoo printing, fixer composition for tattoo printing, ink fixing agent composition for tattoo printing", and can be used interchangeably in this specification.

[0085] In this specification, a fixer composition is a substance that is applied to the skin before or after printing to prevent the ink from coming into contact with the outside or being contaminated by external substances. The fixer composition can ensure that the ink is firmly fixed on the skin without bleeding, thereby achieving excellent printing quality. Preferably, the fixer composition can be used after the application of the ink composition, but is not limited thereto.

[0086] In this specification, a topcoat composition is a substance used to protect the surface on which the ink composition is printed after the ink composition is printed. It can be used for the same purpose as the fixer composition and can contain the same components. The topcoat composition can generally be used without limitation as long as it is a substance for coating the ink composition, and the present invention is not limited thereto.

[0087] In this specification, an ink immobilizer is a substance that is applied to the skin before or after printing to accelerate the skin adsorption rate and drying rate of the ink and promote the formation of a coating layer on the skin. The ink immobilizer can ensure that the ink is printed on the skin without bleeding, thereby achieving excellent printing quality. Preferably, the ink immobilizer composition can be used before the application of the ink composition, but is not limited thereto.

[0088] In this specification, a primer composition is a substance that is applied onto the skin or a medium and forms a layer on the skin or the medium for receiving ink. The ink can be received by the primer layer formed on the skin or the medium, and the fixing power of the ink is improved compared to the skin or the medium where the primer composition is not applied, and the durability of the printed image can be improved. In particular, the primer composition can improve the interaction with an aqueous ink so that a medium not suitable for printing an aqueous ink can receive the aqueous ink. The primer composition can be used for the same applications as the immobilizing agent composition and can contain the same components. The primer composition can be used without limitation as long as it is a substance usually used to improve the ink receptivity of the surface where the ink composition is applied, and the present invention is not limited thereto.

[0089] The ink immobilizing agent composition for tattoo printing of the present invention is for treating the skin before or after injecting ink. By relatively reducing the content of plate-like powder and increasing the content of spherical powder, it is possible to reduce the heterogeneous feeling (such as cloudiness) when applied to the skin and fill the fine wrinkles of the skin without gaps. The powder can be used without particular limitation as long as it is used in ordinary cosmetics, and the powder can include spherical powder or plate-like powder.

[0090] The content of the spherical powder shows an effect of alleviating bleeding at 50% by weight or more based on the total content of the ink immobilizing agent composition. In particular, the content of the spherical powder is very excellent at 54 to 89% by weight based on the total content of the ink immobilizing agent composition. The plate-like powder may be further included so as to improve the skin adhesion of the spherical powder and facilitate skin fixation of printing.

[0091] The plate-like powder can be selected from the group consisting of talc, mica, synthetic fluorophlogopite, sericite, illite, perlite, montmorillonite, boron nitride, bismuth oxychloride, barium sulfate, and alumina.

[0092] The ink fixative composition for tattoo prints of the present invention preferably contains 54 to 89% by weight of spherical powder or 5 to 35% by weight of plate-like powder based on the total content of the ink fixative composition. The spherical powder can more preferably be contained in an amount of 59 to 84% by weight based on the total content of the ink fixative composition. The plate-like powder can more preferably be contained in an amount of 10 to 30% by weight based on the total content of the ink fixative composition.

[0093] In addition, in order to further improve powder scattering and adhesion to the skin of the powder, a binder can be additionally blended. The binder is not particularly limited as long as it is normally used in cosmetics, and diols, ester oils, hydrocarbon oils, silicone oils, etc. can be used. The binder is preferably contained in an amount of 3 to 15% by weight based on 100% by weight of the ink fixative composition for tattoo prints. The binder can more preferably be contained in an amount of 5 to 10% by weight.

The average size of the particles of the spherical powder is 12 μm or less, preferably 3 to 10 μm, and more preferably 5 to 9 μm.

[0095] The spherical powder is preferably composed of a component having excellent water absorption or oil absorption. A component with good water absorption or good oil absorption is effective in preventing bleeding of aqueous ink. In particular, a liquid-absorbing component having excellent water absorption and oil absorption has the greatest effect in preventing bleeding of aqueous ink.

[0096] The spherical powder is preferably selected from the group consisting of silica, polymethyl methacrylate, methyl methacrylate cross polymer, nylon-12, polymethylsilsesquioxane, vinyl dimethicone / methicone silsesquioxane cross polymer, diphenyldimethicone / vinyldiphenyldimethicone / silsesquioxane cross polymer, and HDI / trimethylolhexyl lactone cross polymer. The liquid-absorbing component is preferably silica.

[0097] Silica has a hydrophilic surface and can form a porous coating layer to improve the absorption of ink. It is preferable that silica is used as a component of the spherical powder. In particular, it is preferable to use liquid-absorbing silica having excellent hydrophilicity and lipophilicity. The sum of the water absorption amount and the oil absorption amount can be 0.8 ml / g or more. The liquid-absorbing silica preferably has a water absorption amount of 0.4 ml / g or more and an oil absorption amount of 0.45 ml / g or more. The liquid-absorbing silica preferably has a water absorption amount of 0.4 ml / g to 2.8 ml / g and an oil absorption amount of 0.45 ml / g to 4 ml / g. The tattoo print ink fixing agent composition of the present invention preferably contains 16% or more, 26% or more, 36% or more, or 46% or more of spherical powder having a sum of water absorption amount and oil absorption amount of 4 ml / g or more based on the total content of the spherical powder.

[0098] In this specification, the ink can contain a coloring agent used for printing, painting, writing, etc. The coloring agent is used as a general term for liquid coloring agents or solid coloring agents. The coloring agent can contain a pigment or a dye, and preferably can contain an aqueous dye.

[0099] The aqueous ink is a composition mainly composed of a water-soluble dye and can be used without limitation as long as it is a component usually used in cosmetics. When the ink is used in a printing device, in order to prevent nozzle clogging, improve the ink ejection property, and improve the usability of the printer, the viscosity of the ink is preferably 2 to 5 cps (25 degrees, Enhanced UL Adapter, 60 rpm, Brookfield LTV).

[0109] Since the powder cosmetic composition is used for makeup (cosmetic effect, defect covering), as the powder cosmetic composition, powders with a large clouding effect (the phenomenon that the skin turns white) are mainly used. However, when using the ink fixing agent composition for tattoo prints, if a clouding phenomenon occurs, the printed image may be blurred due to clouding, so the print quality may deteriorate. Therefore, it is preferable that the ink fixing agent composition does not cause a clouding phenomenon.

[0110] Using a ruby cell puff, each of the raw materials A-I powder raw materials was applied to the lower arm part of the arm, and the clouding phenomenon was visually evaluated (H = high, M = medium, L = low).

[0111] Haze and direct transmittance were measured to relatively compare the degree of occurrence of the clouding phenomenon (Haze: the higher, the more clouding, opaque; direct transmittance (parallel transmittance): the higher, the less clouding, transparent).

[0112] Haze is a phenomenon in which when light passes through a transparent material, depending on the type of material, in addition to reflection and absorption, the light rays are diffused according to the inherent properties of the material, showing an opaque cloudy appearance. The percentage of the incident light rays on a transparent object that are diffused is called haze.

[0113] The direct transmittance can be the percentage of the light transmitted in the same direction as the incident direction with respect to the light incident on a transparent material. For example, among the light incident in a direction parallel to the normal direction of a transparent material, the percentage of the light transmitted through the material in the direction parallel to the normal direction can be defined as the transmittance.

[0114] Each raw material was applied to the skin, and printing was carried out on the raw material application site with a skin printing device. As the ink used for printing, a tattoo printing ink containing 25% by weight of a humectant, containing one or more surfactants selected from polyglyceryl-4 caprate and PEG-7 glyceryl cocoate, and further containing one or more defoaming agents selected from glycereth-26, hydrogenated olive oil ethylhexyl, and hydrogenated olive oil saponification-free product was used. At this time, the bleeding occurring at the printing interface was observed, and the bleeding mitigation effect of the tattoo printing ink immobilizer composition was evaluated.

[0115] As shown in Table 1 below, the degree of occurrence of the clouding phenomenon due to the form of the raw material and the bleeding mitigation effect were confirmed.

[0116] Bleeding mitigation evaluation method: ◎: When observed visually, there is no bleeding of the ink; ○: When observed visually, the ink bleeds into fine wrinkles, but the boundary is clear; △: When observed visually, the ink bleeds and the boundary is ambiguous; -: No effect.

[0117]

Table 1

[0118] The actual skin surface was observed as shown in the photograph of FIG. 2 below.

[0119] When the raw materials (Raw materials A to I) used in the tattoo print ink fixing agent composition of the present invention are first applied to the skin and then the ink is printed, it can be confirmed that the ink does not easily seep along the wrinkles of the skin and the seepage phenomenon of the ink is clearly regulated as compared with the case where the ink is printed without applying the fixing agent composition (uncoated).

[0120] In particular, when using plate-like raw materials (Raw materials A to E) compared to using spherical raw materials (Raw materials F to I) having a spherical form, a turbidity phenomenon occurs more frequently, and therefore, there is a drawback that the applied part is more noticeable. It can be confirmed that the plate-like raw materials have a relatively high haze value and a low direct transmission rate compared to the spherical raw materials. Also, looking at the quality of the printed image, it can be seen that the spherical raw materials are excellent in the seepage mitigation effect.

[0121] Experimental Example 2: Confirmation of the bleeding mitigation effect based on the size of the raw materials of the ink fixing agent composition for tattoo printing

[0122] The particle size, oil absorption amount, and water absorption amount of the spherical raw materials were measured and compared with each other.

[0123] Using a ruby cell puff, Raw materials F to L were applied to the lower arm part of the arm, and ink was printed on the raw material application part with a skin printing device. The ink used during printing was the same ink as that used in Experimental Example 1. The degree of seepage occurring at the printing interface was observed, and the seepage mitigation effect was evaluated.

[0124] Seepage mitigation evaluation method: ◎: When observed visually, there is no seepage phenomenon of the ink; ○: When observed visually, the ink seeps into fine wrinkles but the boundary is clear; △: When observed visually, the ink seeps and the boundary is ambiguous; -: No effect.

[0125] As shown in Table 2 below, the seepage mitigation effect according to the size of the raw materials was confirmed.

[0126]

Table 2

[0127] When the particle size of the raw material exceeds 12 μm, the bleeding mitigation effect is inferior. When the particle size of the raw material is 5 to 9 μm, the bleeding mitigation effect is excellent. However, there was no significant difference in the bleeding mitigation effect due to the particle size when the particle size was within 5 to 9 μm.

[0128] Furthermore, when the particle size is within 5 to 9 μm, it was confirmed that the greater the sum of the water absorption and oil absorption, the better the bleeding mitigation effect. When both the oil absorption and water absorption are large, the bleeding mitigation effect is the best. When either the oil absorption or water absorption is large, it was confirmed that the bleeding mitigation effect is good. Therefore, it is preferable that the raw material has high oil absorption and water absorption. Specifically, as the raw material for the tattoo print ink fixing agent composition, it is preferable that the sum of the oil absorption and water absorption is 0.8 ml / g or more.

[0129] The actual skin surface was observed as shown in the photograph of FIG. 3 below.

[0130] When comparing raw material F and raw material G having similar sizes, the bleeding mitigation effect of raw material G having a high water absorption is superior to that of raw material F whose powder surface of the raw material is hydrophobically coated and has no water absorption.

[0131] When comparing raw materials G to I composed of the same silica, the bleeding mitigation effect of raw material G having a small size and excellent oil absorption and water absorption is excellent.

[0132] Experimental Example 3: Confirmation of the performance (bleeding mitigation, usability, transparency) based on the mixing ratio of the ink fixing agent composition for tattoo printing

[0133] Each component element of the tattoo print ink fixing agent composition manufactured according to the present invention was formulated as shown in Table 3 below.

[0134]

Table 3

[0135] The powder parts of the compositions of each of the examples and the comparative examples were placed in a 5 L Henschel mixer with an impeller, and while stirring at 2,000 rpm and 1,000 rpm for 5 minutes, the oil binder part was sprayed. After all of the oil binder part was sprayed, it was mixed at 2,000 rpm for 3 minutes so that the oil binder part was uniformly mixed with the powder part. Then, a grinding process was performed to improve the dispersion degree of the oil binder part, and it was filtered through a 50 mesh screen. Thereafter, an aging process of leaving it standing for 24 hours was performed to remove non-uniform pores present in the mixture.

[0136] The bleeding mitigation effect of the compositions of each of the examples and the comparative examples was printed with a skin printing device, and the degree of bleeding occurring at the printing interface was observed. The ink used during printing was the same ink as that used in Experimental Example 1. Also, a blind test was conducted on 10 women aged 20 - 40, and sensory evaluations such as powder scattering during application, adhesion to the skin, and transparency were performed.

[0137] The bleeding mitigation effect, usability, and transparency of Examples 1 to 4 and Comparative Examples 1 to 2 were evaluated, and the results are shown in FIG. 4 below.

[0138] Bleeding mitigation evaluation method: ⊙: When visually observing, there is no phenomenon of ink bleeding; ○: When visually observing, the ink bleeds into fine wrinkles, but the boundary is clear; △: When visually observing, the ink bleeds and the boundary is ambiguous; -: No effect.

[0139] Usability evaluation method: ⊙: During application, no visual powder scattering is visible; ○: During application, powder scattering is visually confirmed, but it adheres to the skin; △: During application, powder scattering is visually confirmed, but it is difficult to adhere to the skin; -: During application, the powder scatters very much and it is difficult to use.

[0140] Transparency evaluation method: ⊙: When visually observing, it represents the original color of the skin; ○: When visually observing, a faint white feeling is confirmed on the skin; △: When visually observing, a white feeling is confirmed on the skin; -: When visually observing, a heterogeneous white feeling is confirmed on the skin.

[0141] As shown in the results of FIG. 4, Examples 1 to 4 and Comparative Example 1 in which raw material G, which is excellent in water absorption and oil absorption and relatively small in size, was applied at a content of 60% or more showed the most excellent performance in suppressing bleeding. Comparative Example 1 with a low content of plate-like powder and Example 1 containing alumina showed the most excellent performance in transparency. Comparing Examples 2 to 4 with Comparative Example 2, as the content of the plate-like powder in the composition increased, the cloudiness of the composition increased and the transparency deteriorated. Therefore, the composition with excessive addition of the plate-like powder was not suitable for use as an immobilizing agent. However, comparing Examples 1 to 4 with Comparative Example 1, if the plate-like powder is not added, the usability of the composition may be inferior. Therefore, it is preferable that the plate-like powder is applied in the composition below a certain content so as to improve the usability without significantly affecting the bleeding suppression effect.

[0142] Each component element of the tattoo print ink fixing agent composition produced according to the present invention was formulated as shown in Table 4 below.

[0143]

Table 4

[0144] The bleeding suppression effect, usability, and transparency of Example 1, Example 5, and Comparative Example 3 were evaluated, and the results are shown in FIG. 5 below. The ink used during printing was the same ink as that used in Experimental Example 1.

[0145] Bleeding suppression evaluation method: ◎: When observed visually, there is no phenomenon of ink bleeding; ○: When observed visually, the ink bleeds into fine wrinkles, but the boundary is clear; △: When observed visually, the ink bleeds and the boundary is ambiguous; -: No effect.

[0146] Usability evaluation method: ◎: When applying, no visible powder scattering is observed visually; ○: When applying, powder scattering is confirmed visually, but it adheres to the skin; △: When applying, powder scattering is confirmed visually, but it is difficult to adhere to the skin; -: When applying, powder scatters very much visually and it is difficult to use.

[0147] Transparency evaluation method: ◎: When observed visually, it represents the original color of the skin. ○: When observed visually, a faint white feeling is confirmed on the skin. △: When observed visually, a white feeling is confirmed on the skin. -: When observed visually, a heterogeneous white feeling is confirmed on the skin.

[0148] As shown in Fig. 5, when applying Raw Material I at a high content, some bleeding occurred, and a satisfactory bleeding mitigation effect could not be achieved.

[0149] In Table 2, considering that the greater the water absorption and oil absorption, the better the bleeding mitigation effect, it is preferable to use silica with a large sum of oil absorption and water absorption. The sum of the oil absorption and water absorption of silica (Raw Material G) is 5.5 to 6.8 ml / g, and the sum of the oil absorption and water absorption of silica (Raw Material I) is 2.8 to 3.0. Looking at the results in Fig. 5, for the ink immobilizing agent composition for tattoo prints according to the present invention, it is preferable that spherical powder with a sum of oil absorption and water absorption of 4 ml / g or more, preferably 5 ml / g or more, is contained at 16% or more, 26% or more, 36% or more, or 46% or more based on the total content of the spherical powder.

[0150] Each component of the ink immobilizing agent composition for tattoo prints manufactured according to the present invention was formulated as shown in Table 5 below.

[0151]

Table 5

[0152] The bleeding mitigation effects, usability, and transparency of Example 1, Example 6, Comparative Example 4, and Comparative Example 5 were evaluated, and the results are shown in Fig. 6 below. The ink used during printing was the same ink as that used in Experimental Example 1.

[0153] Bleeding mitigation evaluation method: ◎: When observed visually, there is no phenomenon of ink bleeding. ○: When observed visually, the ink bleeds into fine wrinkles, but the boundary is clear. △: When observed visually, the ink bleeds and the boundary is ambiguous. -: No effect.

[0154] Usability evaluation method: ◎: When applying, no visible powder scattering is observed visually; ○: When applying, powder scattering is confirmed visually, but it adheres to the skin; △: When applying, powder scattering is confirmed visually, but it is difficult to adhere to the skin; -: When applying, the powder scatters very much visually and it is difficult to use.

[0155] Transparency evaluation method: ◎: When observed visually, it represents the original color of the skin; ○: When observed visually, a slight white feeling is confirmed on the skin; △: When observed visually, a white feeling is confirmed on the skin; -: When observed visually, a heterogeneous white feeling is confirmed on the skin.

[0156] Hexyl laurate was used as a binder to adjust the adhesion and usability of the composition. As shown in Figure 6, the binder is preferably 3 to 15% by weight, more preferably 5 to 10% by weight based on the total weight of the composition.

[0157] Experimental Example 4: Confirmation of skin irritation compared with the liquid phase composition of the ink immobilizer composition for solid phase tattoo prints

[0158] The liquid phase ink immobilizer composition for tattoo prints can serve as an immobilizer on the skin by being dried on the skin. At this time, in order to assist the drying of the liquid phase ink immobilizer composition for tattoo prints, ethanol and a film-forming agent can be added to the liquid phase ink immobilizer composition.

[0159] Experimental Example 4-1 : The drying rate and skin irritation of the composition depending on the ethanol content were evaluated by the following experimental methods.

[0160] 1) As shown in Table 6 below, an ink immobilizer composition for liquid phase tattoo prints with 10% of a film-forming agent (film-forming agent: Methacryloyl Ethyl Betaine / Acrylates Copolymer) was produced by changing the ethanol content.

[0161]

Table 6

[0162] 2) Apply one drop of the liquid-phase ink immobilizing agent composition to a 1 x 2 cm square area of the skin under the conditions of 24.5°C and 30% humidity, and measure the drying time.

[0163] 3) Evaluate the skin irritation (such as skin tightness, tingling, redness, etc.) after drying.

[0164] Skin irritation evaluation method: -: No abnormality, +: Slight tingling / soreness / redness, ++: Severe tingling / soreness / redness, +++: Intense tingling / soreness / redness.

[0165] As shown in Table 7 below, as the ethanol content in the liquid-phase tattoo print ink immobilizing agent composition increases, the drying rate of the composition increases, but the skin irritation of the liquid-phase ink immobilizing agent composition increases.

[0166]

Table 7

[0167] Experimental Example 4-2 : The skin irritation and ease of cleansing of the ink immobilizing agent composition due to the content of the film-forming agent were evaluated by the following experimental methods.

[0168] 1) As shown in Table 8 below, change the content of the film-forming agent to produce a liquid-phase tattoo print ink immobilizing agent composition.

[0169]

Table 8

[0170] 2) Apply one drop of the liquid-phase ink immobilizing agent composition to a 1 x 2 cm square area of the skin under the conditions of 24.5°C and 30% humidity, and let it dry.

[0171] 3) After drying, evaluate skin irritation (skin tightness, tingling, redness, etc.) and ease of cleansing (whether the ink fixing agent composition can be easily removed from the skin).

[0172] - Irritation evaluation method: -: No abnormality, +: Slight tingling / soreness / redness, ++: Severe tingling / soreness / redness, +++: Intense tingling / soreness / redness.

[0173] - Cleansing evaluation method: +++: Can be removed with lukewarm water, ++: Can be removed by rubbing with cleansing foam 30 times, +: Can be removed by rubbing with cleansing foam 60 times, -: Residue remains even after rubbing with cleansing foam 100 times.

[0174] Referring to Table 9 below, as the content of the film-forming agent in the liquid-phase tattoo print ink fixing agent composition increases, the skin irritation of the liquid-phase ink fixing agent composition increases and it becomes more difficult to cleanse.

[0175]

Table 9

[0176] Experimental Example 4-3: The skin irritation and ease of cleansing of the solid-phase tattoo print ink fixing agent composition were evaluated by the following experimental method.

[0177] 1) Apply the solid-phase ink fixing agent composition to a 1x2 cm square area of the skin under the conditions of 24.5 °C and 30% humidity.

[0178] 2) Evaluate skin irritation (skin tightness, tingling, redness, etc.) and ease of cleansing (whether the ink fixing agent composition can be easily removed from the skin).

[0179] - Irritation evaluation method: -: No abnormality, +: Slight tingling / soreness / redness, ++: Severe tingling / soreness / redness, +++: Intense tingling / soreness / redness.

[0180] - Cleansing evaluation method: +++: Can be removed with warm water, ++: Can be removed by rubbing with the cleansing foam 30 times, +: Can be removed by rubbing with the cleansing foam 60 times, -: Residues remain even after rubbing with the cleansing foam 100 times.

[0181] As shown in Table 10 below, it was confirmed that the solid-phase ink fixing agent composition has no skin irritation and excellent cleansing ease (stick type: a dosage form obtained by solidifying moisture using sodium stearate as an aqueous phase hardness-forming agent, powder type: a dosage form obtained by pulverizing and homogenizing liquid-absorbing silica).

[0182]

Table 10

[0183] Thus, the solid-phase ink fixing agent composition is fixed immediately after application and does not contain additional components such as ethanol or film-forming agents, so it does not irritate the skin. In addition, the solid-phase ink fixing agent composition is easier to cleanse than the liquid-phase ink fixing agent composition, and users can use it conveniently.

[0184] Experimental Example 5: Confirmation of the skin surface homogenization effect compared with the liquid phase composition of the ink fixing agent composition for solid phase tattoo printing

[0185] The homogenization effect of the tattoo print ink fixing agent composition was evaluated by the following experimental method.

[0186] 1) Using an ANTERA 3D device, measure the roughness (Roughness, Ra) of the artificial skin surface 5 times and then derive the average value. The unit of roughness is an arbitrary unit.

[0187] 2) Apply the liquid-phase and solid-phase tattoo print ink fixing agent compositions to the artificial skin respectively and measure the roughness (for the liquid-phase ink fixing agent composition, Liquids 1 - 3 are used, and for the solid-phase ink fixing agent composition, the powder type and stick type are used).

[0188] 3) Compare the roughness values to compare the skin surface homogenization effect of the ink fixing agent composition.

[0189] The following Figure 7 shows that the average surface height of the entire skin image is set to 0, and the surface height between +0.05 mm (red) and -0.05 mm (purple) is represented by color according to the Scale bar. The more red and purple regions there are, the greater the difference in surface height depending on the position, indicating a greater roughness.

[0190] Looking at the skin image in Figure 7, regardless of the state of the ink fixing agent composition, it was confirmed that the ink fixing agent composition can make the skin more uniform when applied compared to when not applied. When comparing the liquid-phase ink fixing agent composition and the solid-phase ink fixing agent composition, when the solid-phase ink fixing agent composition is applied, there are fewer red and purple regions compared to when the liquid-phase ink fixing agent composition is applied, indicating that the solid-phase ink fixing agent composition can make the skin more uniform.

[0191] Figure 1 is a graph showing the roughness values of the artificial skin surface according to the type of ink fixing agent composition for tattoo prints.

[0192] Referring to Figure 1, the roughness value is 29.6 when the ink fixing agent composition is not applied to the skin (uncoated), 27.4 when the liquid-phase ink fixing agent composition is applied to the skin. When the solid-phase ink fixing agent composition is applied to the skin, the powder type has a roughness value of 24.4, and the stick type has a roughness value of 22.8.

[0193] When the ink fixing agent composition is applied, the skin roughness value is smaller than when the ink fixing agent composition is not applied. When the solid-phase ink fixing agent composition is applied, the skin roughness value is smaller than when the liquid-phase ink fixing agent composition is applied. Since a smaller roughness value indicates that the skin surface is more uniform, regardless of the state of the ink fixing agent composition, the ink fixing agent composition can make the skin more uniform when applied compared to when not applied. Also, when comparing the liquid-phase ink fixing agent composition and the solid-phase ink fixing agent composition, the solid-phase ink fixing agent composition can make the skin more uniform than the liquid-phase ink fixing agent composition.

[0194] Experimental Example 6-1: Inhibitory performance of the ink composition against solidification based on the type and content of the humectant

[0195] The state of the ink composition after drying was confirmed according to the type / content of the humectant contained in the tattoo print ink composition.

[0196] The ink composition contained 5 wt% of a colorant (Yellow No. 4, manufacturer: BOLAK), contained a humectant as shown in Table 11 below, and the remaining content other than the humectant was filled with purified water (to 100 wt%). Each ink composition was divided into a certain amount and left overnight in a high-temperature chamber at 50 °C, and the state of each ink composition was observed.

[0197] Solidification inhibition evaluation method: ○: Completely liquid form, △: It was confirmed that solidification was partially inhibited, X: Completely solid form.

[0198] As shown in Table 11 and Figure 8 below, for the ink composition, in the case of DPG (dipropylene glycol) and 1,3-BG (1,3-butylene glycol), even when containing 25 wt% or more, solidification proceeded, but when PEG-8 was 15 wt% or glycerin was 10 wt% or more, it was confirmed that the solidification of the ink composition was inhibited. When PEG-8 was 20 wt% or more or glycerin was 15 wt% or more, no solidification of the ink composition appeared at all.

[0199]

Table 11

[0200] Specifically, in FIG. 8 below, an ink composition containing 25% of a humectant is shown according to the type of the humectant (humectant 25%), an ink composition containing PEG-8 is shown according to the content of the humectant (PEG-8), and an ink composition containing glycerin is shown according to the content of the humectant (glycerin).

[0201] According to Table 11 and FIG. 8 above, the tattoo-printing ink composition according to an embodiment of the present invention preferably contains a humectant in an amount of 10 to 40% by weight, or 15 to 30% by weight, based on the total weight % of the ink composition. More preferably, it can contain PEG-8 in an amount of 15 to 40% by weight, or 15 to 30% by weight; or glycerin in an amount of 10 to 40% by weight, or 10 to 30% by weight.

[0202] Experimental Example 6-2: Inhibitory performance of the ink composition against solidification based on the content of the humectant mixed with PEG-8 and glycerin

[0203] The ink composition contains 5% by weight of a colorant (Yellow No. 4, manufacturer: BOLAK). As a humectant, PEG-8 and glycerin were used in combination as shown in Table 12 below. The remaining content other than the humectant was filled with purified water (to 100% by weight). Each ink composition was divided into a certain amount and left overnight in a high-temperature chamber at 50 °C, and the state of each ink composition was observed.

[0204] Solidification inhibition evaluation method: ○: Complete liquid phase form, △: It was confirmed that solidification was partially inhibited, X: Complete solid form.

[0205] The tattoo-printing ink composition according to an embodiment of the present invention preferably contains a mixed humectant of PEG-8 and glycerin in an amount of 15 to 40% by weight, or 20 to 30% by weight, based on the total weight % of the ink composition.

[0206]

Table 12

[0207] Experimental Example 7: Evaluation of the impregnation property of the ink composition on the sponge for ink storage based on the type of surfactant

[0208] On the one hand, the ink composition is generally stored in a cartridge, and a sponge for holding the ink is provided in the cartridge. At this time, the sponge is impregnated with the ink so that the ink does not leak to the outside in the cartridge, and the ink will be appropriately supplied to the nozzles during printing. The sponge impregnated with the ink can be mainly manufactured from polyurethane, and due to the porous structure having a uniform porosity, the polyurethane foam can have excellent ink holding ability.

[0209] When the impregnability of the ink composition with respect to the sponge is low, there is a problem that it takes a long time to fill the ink composition into the cartridge or the sponge. Therefore, in order to solve such a problem, it is necessary to improve the impregnability of the ink composition.

[0210] For stable continuous ejection of the ink composition, the ink composition should be well impregnated into the sponge and no bubbles should be generated in the ink composition. In order to improve the sponge impregnability of the ink composition and reduce the amount of bubbles generated, the ink composition preferably contains a surfactant. Below, the sponge impregnability of the ink composition depending on the type of surfactant was confirmed.

[0211] As shown in Table 13 below, the sponge impregnability was evaluated by the time it takes for each surfactant to be absorbed after dropping 5 μl of each surfactant onto a polyurethane sponge (inner sponge of HP62 empty (3UB14A)) with a micropipette (impregnability: ◎ = immediately absorbed, ○ = absorbed within 10 minutes, △ = absorbed within 1 hour, X = not absorbed, HLB: hydrophilic-lipophilic balance, Hydrophile-Lipophile Balance).

[0212] Among the surfactants, it was confirmed that polyglyceryl-4 caprate and PEG-7 glyceryl cocoate were rapidly absorbed by the sponge and showed excellent impregnation properties.

[0213]

Table 13

[0214] The ink composition can contain components as shown in Table 14 below, and as surfactants, it can contain PEG-7 glyceryl cocoate and polyglyceryl-4 caprate. When the ink composition contains PEG-7 glyceryl cocoate and polyglyceryl-4 caprate as surfactants, it was confirmed that it has excellent impregnation properties. The ink composition according to the present invention preferably contains PEG-7 glyceryl cocoate or polyglyceryl-4 caprate in an amount of 0.001 to 10% by weight, preferably 0.01 to 5% by weight, based on the total content of the ink composition.

[0215]

Table 14

[0216] Experimental Example 8: Evaluation of the inhibitory performance of the ink composition against bubble generation based on the type and content of the defoaming agent

[0217] On the other hand, since air bubbles are dispersed in the ink composition, it is preferable that an antifoaming agent (defoaming agent) for preventing the generation of air bubbles or destroying air bubbles is contained in the ink composition in order to remove the air bubbles. When an antifoaming agent is contained, the generation of air bubbles in the ink composition is suppressed, and the discharge stability of the ink composition is improved.

[0218] In addition, the defoaming agent contained in the ink composition preferably has selective miscibility. This is because when the defoaming agent has excellent compatibility with the ink composition, the defoaming agent is mixed with the ink composition without moving to the bubble film, resulting in a weak defoaming effect. When the compatibility is not excellent, the defoaming agent may cause a haze phenomenon in the ink composition, which may cause printing defects in the ink composition. Therefore, the defoaming agent contained in the ink composition must have appropriate compatibility with the ink composition.

[0219] Generally, particulate silicone defoaming agents used in cosmetics may clog the nozzles when used in ink compositions and are not excellent in compatibility with tattoo print ink compositions. Therefore, particulate silicone defoaming agents are not suitable for use in tattoo print ink compositions. Also, in the case of silicone, recently, concerns about its danger to the human body and environmental pollution have been raised, and it is an undesirable component to use.

[0220] In addition, defoaming agents containing ethanol components are mainly used as defoaming agents for cosmetics. However, since ethanol components are volatile, they may cause nozzle clogging when contained in ink compositions and are not suitable components to use.

[0221] Below, the amount of bubbles generated when the ink composition containing each defoaming agent was shaken according to the type and content of the defoaming agent was confirmed. Looking at Table 15 below, when glyceres-26 (a polyethylene glycol ether composed of 26 moles of ethylene oxide and glycerin) was included, it was confirmed that the amount of bubbles generated decreased compared to the ink composition (Ink Composition 3) without glyceres-26.

[0222]

Table 15

[0223] An ink composition according to an embodiment of the present invention can contain an antifoaming agent so as to suppress the generation of bubbles and quickly eliminate the generated bubbles. The ink composition according to the present invention preferably contains the antifoaming agent in an amount of 0.001 to 10% by weight, preferably 0.01 to 5% by weight, based on the total content of the ink composition.

[0224] Experimental Example 9: Evaluation of the bubble removal performance of the ink composition using plant-derived oil

[0225] In the following, when adding a plant-derived oil (hydrogenated olive oil ethylhexyl and hydrogenated olive oil unsaponifiable matter, viscosity: 20 cs (Spindle LV1, Speed 60 rpm, Temperature 20 ± 0.2 °C), surface tension: 31.5 dyne / cm) as an antifoaming agent to the ink composition, the degree of bubbles generated when the ink composition containing each surfactant was shaken and the degree to which the bubbles were removed over time were confirmed.

[0226]

Table 16

[0227] The plant-derived oil has an antifoaming effect similar to that of silicone (dimethyl silicone viscosity: 100 cs (Spindle LV1, Speed 60 rpm, Temperature 20 ± 0.2 °C), surface tension: 21.5 dyne / cm) and can have a surface tension of 50 dyne / cm or less.

[0228] The ink composition according to the present invention can contain a plant-derived oil as an antifoaming agent, and preferably can contain any one of hydrogenated olive oil ethylhexyl and hydrogenated olive oil unsaponifiable matter. The plant-derived oil is preferably contained in an amount of 0.1 to 10% by weight, preferably 0.1 to 5% by weight, and most preferably 0.1 to 2% by weight based on the total content of the ink composition.

[0229] Experimental Example 10: Evaluation of the image sharpness based on the type and content of the surfactant

[0230] The ink composition is discharged in the form of droplets from the outlet of the nozzle. The ink composition is delivered to a specific position in the form of droplets, and printing occurs at the corresponding position. When the nozzle moves at high speed while discharging the ink composition, if the droplet formation time becomes long and the droplet length becomes long, when the nozzle moves, the ink droplet cannot be printed only at a specific position, and the tail of the droplet may affect the printing at other positions. If the ink droplet affects the printing at other positions, the sharpness of the ink composition may decrease. Therefore, the sharpness may be affected by the time when the ink droplet is formed at the nozzle outlet, the droplet length, and the like.

[0231] On the other hand, when the ink droplet is ejected to the outside, the greater the surface tension of the ink, the more it tends to reduce the surface area of the ink in contact with the air to lower the surface energy, and the ink can form the shape of a droplet in a short time. Therefore, the ink with a large surface tension has a short time (breakup time) for the tail of the droplet to be separated from the nozzle and a short distance (breakup distance) from the end of the nozzle to the tip of the droplet. Therefore, when the surface tension of the ink is large, the volume of the droplet is small, the speed of the droplet is slow, and the number of satellites is small.

[0232] When printing the ink at high speed, it is preferable that the separation time and the separation distance are short, and it is also preferable that the volume of the droplet is appropriately adjusted. Therefore, in order to maintain stable droplet ejection during the printing of the ink, it is preferable that the surface tension of the ink maintains an appropriate value.

[0233] In particular, since the aqueous ink contains a large amount of water with a large surface tension, it is important to appropriately control the surface tension of the aqueous ink. A surface tension modifier, a surfactant, etc. can be used for controlling the surface tension. The surfactant added to the ink composition can perform a function of adjusting so that the ink composition has excellent printing quality when printed by appropriately adjusting the surface tension.

[0234] Hereinafter, the sharpness of the image depending on the type and content of the surfactant was evaluated. For the evaluation, ink compositions 11 to 13 were prepared as shown in Table 17 below.

[0235]

Table 17

[0236] In the following Figure 9, when ink compositions 11 to 13 were printed on paper under the same conditions, it was confirmed whether the three-color inks were printed clearly. The HP HI LX ink is a finished ink cartridge using the same standard cartridge container sold by HP, and was used to compare the printing quality with the ink composition of the present invention. Looking at the following Figure 9, it was confirmed that ink compositions 12 and 13 have the sharpness only of the HP HI LX ink.

[0237] Experimental Example 11: Evaluation of the image sharpness using the surfactant and the defoaming agent

[0238] For the evaluation, ink compositions 14 to 18 were prepared as shown in Table 18 below.

[0239]

Table 18

[0240] In the following Figure 10, when ink compositions 14 to 18 were printed on paper under the same conditions, it was confirmed whether the three-color inks were printed clearly. It was confirmed that ink compositions 16, 17, and 18 have the sharpness only of the HP HI LX ink, and that ink composition 17 is clearer than ink composition 16.

[0241] Experimental Example 12: Performance evaluation of the fixer composition

[0242] When printing directly or indirectly on the skin, the ink composition is less likely to penetrate the skin due to its structural properties. Also, aqueous inks for skin printing are characterized by a low penetration effect and a long drying time, and may dissolve when the printed substrate comes into contact with water. Therefore, an image applied using an inkjet printing method may tend to bleed or blur when external friction occurs, or the printed image may dissolve and disappear when exposed to a significant amount of aqueous medium (e.g., when the printed article is exposed to water or comes into contact with water through other means).

[0243] To enhance the water resistance and durability of the ink on the skin, a water-soluble polymer can be added as an adhesive component during ink production. However, if the nozzles of the printing equipment are exposed to the outside for a long time, problems with durability may occur, such as the ink remaining in the nozzles drying out and causing nozzle clogging, or detachment occurring on the surface of the printing medium of the output printed matter.

[0244] When aqueous ink is used on the skin, an additional post-treatment agent (fixer, top coat) can be applied after printing to mitigate ink bleeding on the skin, improve persistence, and enhance water resistance.

[0245] The fixer composition is insoluble in relation to the aqueous ink, spreads (spreading) over the skin on which the ink composition is printed and is fixed for a certain period of time, and preferably has a hardness and viscosity above a certain level so as not to run off for usability, preferably forms a film of uniform thickness on the skin, and preferably has no volatility.

[0246] Also, the fixer composition is preferably colorless (transparent) so as not to affect the sharpness of the printed image of the ink composition. Also, it preferably has excellent fixing properties when the ink is applied to the skin, can be applied by a simple method and has usability, has excellent water resistance, and does not cause skin irritation or the like.

[0247] For evaluation, a fixer composition was produced as shown in Table 19 below.

Table 19

[0248] A fixer composition having the content ratio in Table 19 above was applied to the upper surface on which the ink composition was applied, and the corresponding portion was exposed to running water for 30 seconds, and then the remaining printed matter is shown in FIG. 11 below.

[0249] The ink used was the same ink as that used in Experimental Example 1, and Example 1 of Table 5 was used as the ink fixing agent composition before image printing. Referring to FIG. 11, when exposed to water after the fixer was applied (fixer application), the sharpness of the printed matter was superior to that without the fixer applied (no fixer application).

[0250] The fixer composition according to one aspect of the present invention can be formulated into solid, semi-solid, gel, or liquid products, such as gels suitable for topical application, water-soluble jellies, creams, lotions, suspensions, solutions, foams, powders, slurries, ointments, solutions, oils, pastes, sprays, emulsions, balms, etc., and can be used without limitation as long as it is a dosage form that can be used as a fixer composition.

[0251] However, since the fixer composition needs to not run off the skin in order to impart a fixing force to the ink composition, it is preferably in a semi-solid dosage form. As used herein, "semi-solid" can mean having the consistency of cream, ointment, or paste at room temperature (15 to 25 °C), and can mean a substance that has no or little fluidity.

[0252] As the fixer composition, a balm dosage form or a jelly type dosage form is preferably used. The balm dosage form is a dosage form with a texture obtained by mixing essential oil, glycerin, wax, etc. and solidifying it into a semi-solid form. The jelly type dosage form is a dosage form in which a colloidal solution solidifies into a semi-solid state while containing a dispersant.

[0253] The fixer composition is insoluble in aqueous ink and is preferably an oil in a transparent semi-solid state at room temperature. In particular, an oily, water-insoluble semi-solid (semi-solid or paste) or solid state fixer composition can exhibit a water resistance effect immediately without a separate drying time. As the water-insoluble semi-solid or solid state fixer composition, hydrocarbon oil or wax is preferable.

[0254] The fixer composition can contain hydrocarbon oil and can further contain a hydrocarbon wax. When a hydrocarbon wax is added, excellent water resistance can be maintained and the texture and usability can be improved. The fixer composition can preferably contain petrolatum, synthetic wax, ceresin or microcrystalline wax. When the fixer composition contains a synthetic wax, ceresin and microcrystalline wax of a hydrocarbon wax, i) the bleeding of the ink composition after printing is improved (the fixing power is enhanced), ii) the high-temperature stability of the fixer composition is improved, and iii) the usability of the fixer composition is improved (the oily feeling and stickiness during skin application are reduced).

[0255] In particular, petrolatum as a constituent is obtained from high-boiling hydrocarbons and hydrocarbons that are usually liquid at room temperature, and is a soft, oily, semi-solid mixture of hydrocarbons, having the characteristics of being insoluble in water, alcohol and glycerol, and containing only carbon and hydrogen (C n H 2n+2) is a mixture. Petrolatum is colorless but has a pale yellow semi-solid form and can be utilized as a component of the fixer composition. Due to the hydrophobicity (i.e., water-repellency), water-insolubility, and the physical property of existing in a semi-solid form at normal temperature of petrolatum, it has excellent water resistance to the printed surface when applied alone.

[0256] The fixer composition according to the present invention preferably contains 65 to 100% by weight, preferably 65 to 95% by weight, of a hydrocarbon-based oil or wax based on the total weight percentage of the fixer composition.

[0257] Thus, the ink fixing agent composition for tattoo printing according to one aspect of the present invention can prevent the turbidity phenomenon during application and can prevent the bleeding of the ink composition.

[0258] Also, the ink fixing agent composition for tattoo printing according to one aspect of the present invention can prevent scattering (flying) in the air during the application process and can improve the skin adhesion of the ink composition.

[0259] Also, the ink fixing agent composition for tattoo printing according to one aspect of the present invention is a solid-phase ink fixing agent composition, which has less skin irritation and is excellent in cleansing ease compared to the liquid-phase ink fixing agent composition.

[0260] Also, the ink composition for tattoo printing according to one aspect of the present invention can contain a humectant to suppress the solidification of the ink composition, reduce the nozzle clogging of the ink composition, and enable stable ejection of the ink composition.

[0261] Also, the ink composition for tattoo printing according to one aspect of the present invention can contain a surfactant to improve the sponge impregnation property of the ink composition and enable stable spraying of the ink composition.

[0262] Also, the tattoo print ink composition according to one aspect of the present invention contains an antifoaming agent and can easily remove the bubbles formed in the ink composition, enabling stable ejection of the ink composition.

[0263] Also, the tattoo print ink composition according to one aspect of the present invention contains a surfactant or an antifoaming agent and can control the surface tension of the ink composition. Therefore, the ink composition can provide clear printing quality.

[0264] Also, the tattoo print fixer composition according to one aspect of the present invention can have a viscosity such that it does not substantially flow down without an external force. It is applied on the upper surface of the area where the ink composition is applied to block the ink composition from contacting the outside and can improve the skin fixing power of the ink composition.

[0265] Also, the tattoo print fixer composition according to one aspect of the present invention can contain a hydrocarbon-based oil or a hydrocarbon-based wax and have excellent fixing power, high-temperature stability, and excellent usability.

[0266] The tattoo print ink composition according to one aspect of the present invention can have a tattoo print ink immobilizing agent composition applied before or after being printed on the skin.

[0267] Preferably, for the tattoo print ink composition according to the present invention, it is preferable that an immobilizing agent or a primer is used before being printed on the skin, or a fixer or a top coat is used after being printed on the skin. It is possible to use a fixer before the ink is printed on the skin or an immobilizing agent after the ink is printed on the skin. Before and after the ink is printed on the skin, ordinary immobilizing agents (primers) or fixers (top coats) known in the art may be used.

[0268] It is possible to provide an ink fixing agent composition for tattoo printing used before the ink composition is printed on the skin and a fixer composition used after the ink composition for tattoo printing is printed on the skin.

[0269] Furthermore, the present invention can provide a tattoo printing kit including an ink composition for tattoo printing, a fixing agent composition used before the ink composition is printed on the skin, and a fixer composition used after the ink composition is printed on the skin, and including any one or more of the ink composition, the fixing agent composition, and the fixer composition.

[0270] Moreover, the present invention can provide a tattoo printing device including an ink composition for tattoo printing, and the tattoo printing kit can include the tattoo printing device.

[0271] In addition, the present invention provides a tattoo printing method including the steps of applying an ink fixing agent composition to the skin; applying an ink composition to the skin on top of the area where the ink fixing agent composition is applied; and applying a fixer composition to the skin on top of the area where the ink composition is applied.
