Description

Technical Field

[0001] This utility model relates to the field of thermal tattoo paper technology, and in particular to a thermal tattoo paper. Background Technology

[0002] With the development of materials science, temporary tattoos with dynamic changing effects have emerged. Thermochromic technology has been introduced into this field, resulting in thermochromic tattoo paper. These products typically use thermochromic microcapsules in the pattern layer, which contain elliptical dyes, developers, and solvents. When the skin temperature reaches a critical point, the solvent melts, and the dyes react with the developers to reveal the color. When the temperature drops, the color disappears. This characteristic of revealing or hiding the pattern due to changes in body temperature greatly enhances the fun and interactivity of tattoos, and they are widely used in parties, music festivals, and marketing activities.

[0003] However, existing thermal tattoo papers have poor functionality, causing the water-soluble adhesive layer to dissolve upon contact with water. This leads to tattoos easily fading, lifting edges, or blurring during use, especially when swimming, showering, or sweating heavily, significantly shortening their lifespan. Furthermore, the dried tattoo pattern layer is often hard, brittle, and lacks elasticity. When applied to frequently moving areas such as joints and wrists, it can cause tightness, wrinkles, or even cracking, affecting aesthetics and wearing comfort, resulting in a poor user experience. Therefore, these papers suffer from limited functionality, failing to meet customer needs.

[0004] Therefore, those skilled in the art have provided a thermal tattoo paper to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the issue of limited functionality, this invention provides a thermal tattoo paper.

[0006] This utility model provides a thermal tattoo paper, which adopts the following technical solution: A thermal tattoo paper includes a backing paper base layer, a water-soluble adhesive layer on top of the backing paper base layer, a functional layer on top of the water-soluble adhesive layer, a thermal pattern layer on top of the functional layer, a protective layer on top of the thermal pattern layer, the functional layer including an elastic base layer, an isolation layer on top of the elastic base layer, and a fluorescent layer on top of the isolation layer.

[0007] By adopting the above technical solution, the backing paper base layer, water-soluble adhesive layer, functional layer, heat-sensitive pattern layer, and protective layer are combined to construct a heat-sensitive tattoo paper. Simultaneously, the elastic base layer in the functional layer gives the tattoo excellent flexibility and stretchability, allowing it to closely adhere to the skin and remain flat even in highly mobile areas such as joints, preventing wrinkles or cracks, significantly improving wearing comfort and realism. The isolation layer effectively prevents the migration of heat-sensitive material components, avoiding background yellowing and color rendering degradation, ensuring the pattern remains vibrant and stable through multiple temperature cycles, extending its lifespan. The fluorescent layer provides dynamic luminescence under ultraviolet light and other environments, giving the tattoo multi-mode visual expression, enhancing the product's fun and scene adaptability, and meeting personalized decoration needs. Furthermore, the protective layer provides excellent waterproof, sweat-resistant, and abrasion-resistant properties, ensuring the tattoo remains intact and clear during daily washing, sports, or underwater activities, further improving the product's environmental adaptability and durability.

[0008] Optionally, the protective layer includes a waterproof layer, and a protective film is disposed on top of the waterproof layer.

[0009] By adopting the above technical solutions, the waterproof layer can improve the waterproof and sweat-resistant properties of heat-sensitive tattoos, and the protective film can facilitate the protection of heat-sensitive tattoos during production and transportation.

[0010] Optionally, the waterproof layer is disposed on top of the thermal pattern layer, and the material of the waterproof layer is a water-based polyurethane coating.

[0011] By adopting the above technical solution, the waterproof layer material is a water-based polyurethane coating. Polyurethane has excellent thermal insulation properties, is resistant to chemicals, is easy to process, and has good waterproof performance, thereby improving the waterproof performance of heat-sensitive tattoos.

[0012] Optionally, the protective film is made of biaxially oriented polypropylene film, and the protective film and the waterproof layer are adsorbed together.

[0013] By adopting the above technical solution, the protective film material is set as a biaxially oriented polypropylene film. Biaxially oriented polypropylene film is generally a multi-layer co-extruded film, which is made by co-extruded polypropylene particles into sheets and then stretched in both longitudinal and transverse directions. Due to the orientation of stretched molecules, this film has good physical stability, mechanical strength, air tightness, high transparency and gloss, and is tough and wear-resistant, thereby improving the protective performance of heat-sensitive tattoo paper.

[0014] Optionally, the elastic base layer is disposed on top of the water-soluble adhesive layer, and the material of the elastic base layer is an aqueous polyurethane dispersion.

[0015] By adopting the above technical solution, the elastic base material is set as an aqueous polyurethane dispersion. The aqueous polyurethane dispersion is an environmentally friendly polymer material synthesized through a specific chemical process. It is stably dispersed in aqueous solution and does not contain traditional emulsifiers. The material achieves stable dispersion through the self-emulsifying properties of polyurethane prepolymer or ionic monomers (such as sulfonates). It has properties such as chemical corrosion resistance, high wear resistance and low temperature elasticity, which allows the heat-sensitive tattoo to adhere closely to the skin, especially in areas with frequent movement such as joints. It is not easy to produce wrinkles, cracks or tightness, and the wearing experience is more comfortable, natural and imperceptible, which is closer to the effect of real tattoo.

[0016] Optionally, the isolation layer is made of silica nanocomposite material, and the thickness of the isolation layer is 20μm-23μm.

[0017] By adopting the above technical solution, the isolation layer is made of silica nanocomposite material. Silica nanocomposite material is a material made by combining silica as a matrix or filler with other materials (such as polymers, metals, ceramics, etc.) at the nanoscale. It can effectively prevent chemical components (such as leuco dyes and color developers) in the thermal pattern layer from migrating to other layers, thereby avoiding problems such as background yellowing, unclear color development, and performance degradation caused by component migration. It ensures that the thermal pattern always maintains a bright, pure, and stable color during repeated color development / decolorization cycles, improving the reliability and service life of the product.

[0018] Optionally, the fluorescent layer is made of inorganic fluorescent pigment, and the fluorescent layer is disposed at the bottom of the thermal pattern layer.

[0019] By adopting the above technical solution, the fluorescent layer material is set as inorganic fluorescent pigment. Fluorescent pigment is a type of functional pigment that emits light under ultraviolet light. It is widely used in anti-counterfeiting, labeling and decoration. Its light emission principle is based on absorbing ultraviolet light and converting it into visible light. It stops emitting light immediately after the light source is turned off. This multi-interaction greatly enhances the fun and attractiveness of the product and meets users' needs for personalized and dynamic decoration.

[0020] In summary, this utility model has the following beneficial effects: 1. This utility model, by setting up a backing paper base layer, a water-soluble adhesive layer, a functional layer, a heat-sensitive pattern layer, and a protective layer, can jointly construct a heat-sensitive tattoo paper. Simultaneously, the elastic base layer in the functional layer gives the tattoo excellent flexibility and stretchability, allowing it to closely adhere to the skin and remain flat even in highly active areas such as joints, preventing wrinkles or cracks, significantly improving wearing comfort and realism. The isolation layer effectively prevents the migration of heat-sensitive material components, avoiding background yellowing and color rendering degradation, ensuring the pattern maintains vibrant and stable colors during multiple temperature cycles, extending its lifespan. The fluorescent layer provides a dynamic luminescent effect under ultraviolet light and other environments, giving the tattoo multi-mode visual expression, enhancing the product's fun and scene adaptability, and meeting personalized decoration needs. Furthermore, the protective layer provides excellent waterproof, sweat-resistant, and abrasion-resistant properties, ensuring the tattoo remains intact and clear during daily washing, sports, or underwater activities, further improving the product's environmental adaptability and durability. Through the above structure, the overall performance of the heat-sensitive tattoo paper is effectively improved, thereby meeting customer needs.

[0021] 2. This utility model improves the waterproof and sweat-resistant properties of heat-sensitive tattoos by incorporating a waterproof layer. The protective film facilitates protection during the production and transportation of heat-sensitive tattoos. The waterproof layer is made of a water-based polyurethane coating. Polyurethane has excellent thermal insulation properties, is resistant to chemicals, is easy to process, and has good waterproof performance, thus improving the waterproof performance of heat-sensitive tattoos. The protective film is made of biaxially oriented polypropylene film. Biaxially oriented polypropylene film is generally a multi-layer co-extruded film, made by co-extruded polypropylene granules into sheets, and then stretched in both longitudinal and transverse directions. Due to the stretching... Due to its molecular orientation, this film exhibits good physical stability, mechanical strength, airtightness, high transparency and gloss, and is tough and wear-resistant, thus improving its protective performance against heat-sensitive tattoo paper. The elastic base layer is made of water-based polyurethane dispersion, an environmentally friendly polymer material synthesized through a specific chemical process. It is stably dispersed in aqueous solutions and does not contain traditional emulsifiers. This material achieves stable dispersion through the self-emulsifying properties of polyurethane prepolymers or ionic monomers (such as sulfonates), possessing characteristics such as chemical corrosion resistance, high wear resistance, and low-temperature elasticity, enabling heat-sensitive tattoos to... It fits snugly against the skin, especially in frequently moving areas like joints, minimizing wrinkles, cracks, or tightness, resulting in a more comfortable, natural, and imperceptible wearing experience, closely resembling the effect of a real tattoo. The isolation layer is made of silica nanocomposite material, which uses silica as a matrix or filler and is composited with other materials (such as polymers, metals, ceramics, etc.) at the nanoscale. This effectively prevents the migration of chemical components (such as leuco dyes and developers) from the heat-sensitive pattern layer to other layers, thus avoiding problems such as yellowing of the background, unclear color development, and performance degradation caused by component migration. This ensures that the heat-sensitive pattern maintains a bright, pure, and stable color during repeated color development / decolorization cycles, improving the product's reliability and lifespan. The fluorescent layer is made of inorganic fluorescent pigments, which are functional pigments that emit light under ultraviolet light. They are widely used in anti-counterfeiting, labeling, and decoration. Their light-emitting principle is based on absorbing ultraviolet light and converting it into visible light. They stop emitting light immediately when the light source is turned off. This multi-layered interactivity greatly enhances the product's fun and appeal, meeting users' needs for personalized and dynamic decoration. Attached Figure Description
