Embodiment 1

[0149] A transfer sheet was prepared and transferred by in-mold injection molding to obtain an antiviral molded article, and the antiviral properties, total light transmittance, and haze of the antiviral molded article were measured.

[0150] The production method and the like of the transfer sheet are as follows.

[0151] Base sheet: PET film, thickness 50μm (micron)

[0152] Antiviral agent: mixed with TiO 2 Powder 60 parts by weight and Cu 2 O powder 40 parts by weight of powder

[0153] TiO2 The primary particle size of the powder (white powder) is 15nm, Cu 2 The primary particle diameter of the O powder (dark brown powder) was 50 nm.

[0154] Hard coat agent: Urethane acrylate UV curable resin

[0155] Molding resin: Acrylic resin

[0156] Molded product size: 50mm×50mm×1mm

[0157] Molten resin temperature: 240℃~260℃

[0158] On the base sheet, the antiviral agent is 0.02g / m 2 The amount of antiviral agent, methyl ethyl ketone and a small amount of hard coating ...

Embodiment 2

[0176] Using the antiviral molded article produced in Example 1, the antibacterial properties of the antiviral molded article were measured. The antiviral molded articles used in the measurement were sample No. 1 and sample No. 9. In the paragraph describing Example 2, the term "antibacterial property" means antibacterial property as the text indicates, and the term "antibacterial property" does not mean antiviral property.

[0177] The measurement of the antimicrobial property complied with JIS-R-1756 (test method for antiviral property of a visible light-responsive photocatalyst). As the light condition, the light of the white fluorescent lamp was filtered out the ultraviolet rays below 380nm in the N169 filter, so that the illuminance was 1000lx.

[0178] Test method: 50 μL (microliter) of Staphylococcus aureus bacteria solution was dropped on the sample, irradiated with light for 24 hours, and recovered with SCDLP solution. The recovered liquid was mixed with NB medium, ...

Embodiment 3

[0187] The transfer sheet 11 was produced, and the transfer conditions were investigated, and the transfer was performed on a shrink base material, and the antiviral shrink film 1 was produced, and the shrink processability was evaluated.

[0188] The production method and the like of the transfer sheet are as follows.

[0189] Base sheet: PET film, thickness 50μm

[0190] Antiviral agent: mixed with TiO 2 Powder 60 parts by weight and Cu 2 O powder 40 parts by weight of powder

[0191] TiO 2 The primary particle size of the powder (white powder) is 15nm, Cu 2 The primary particle diameter of the O powder (dark brown powder) was 50 nm.

[0192] Shrink base material: a biaxially stretched polystyrene sheet with a thickness of 60 μm, and its thermal shrinkage rate is 14% in the MD direction and 75% in the TD direction when heated at 100° C. for 10 seconds. Here, thermal contraction rate (%)=100×(length before heating−length after heating) / length before heating.

Abstract

A method for producing an antiviral transfer sheet for increasing the density of an antiviral agent / antimicrobial agent on the surface serving as the outermost layer after transfer, wherein the production method obviates the need for a large amount of antiviral agent or the like and eliminates the opacity of the layer having an antiviral function. An inorganic antiviral powder 33 is arranged on one side of a base sheet 31, a hard coat agent 34 is positioned in the form of a layer on top of the inorganic antiviral powder 33, and a functional layer 37 comprising the inorganic antiviral powder and hard coat agent is formed on the base sheet. Next, an antiviral transfer sheet 11 is produced by forming an adhesive layer 39 on top of the functional layer 37 in contact with the functional layer 37 or with other layers interposed therebetween.

Description

technical field [0001] The present invention relates to an antiviral transfer sheet for transferring an antiviral agent layer and an antibacterial layer to the surface of an article made of synthetic resin, natural resin, wood, metal, glass, or the like. Also, the present invention relates to an antiviral shrink film for covering the surface of an article, wherein the surface of the film has antiviral and antibacterial properties. Background technique [0002] From the viewpoint of hygiene, it is desirable to impart antiviral and antibacterial properties to articles that come into contact with human hands, especially hands of an unspecified large number of people. If the transfer sheet including the functional layer is transferred onto the transferred substrate, the functional layer can be provided on the surface of the transferred product. An example of the function of the functional layer is antiviral performance. In addition, shrink films comprising functional layers ca...
