reference example 1

[0083]Into a four-neck flask equipped with a stirring device, a thermometer, an inert gas inlet, and a condenser, 1000 parts of n-butyl acetate was added, and the temperature was raised to 110°C. Then at 110°C, 650 parts of methyl methacrylate, 245 parts of n-butyl methacrylate, 100 parts of 2-hydroxyethyl methacrylate, 5 parts of methacrylic acid, 15 parts of tert-butyl were added dropwise within 4 hours. base peroxy 2-ethylhexanoic acid ester, after the dropwise addition, the temperature was kept at 110° C. to continue the reaction for 6 hours to obtain a vinyl copolymer (a-1) with a non-volatile content of about 50%. The vinyl copolymer (a-1) was dried, and the SP value was measured to be 10.16.

[0084] (Reference example 2~6)

[0085] Vinyl copolymers (a-2) to (a-6) were obtained in the same manner as in Example 1 except that the ratio of the vinyl monomers was changed as shown in Table 1. The results of further drying and measuring SP are shown in Table 1.

Embodiment 1

[0165] For example figure 1 When preparing the resin composition for the surface resin layer 1 shown, about 100 parts by weight of hexafluoropropylene / ethyl vinyl alcohol / VEOVA9 / adipic acid mono- Copolymer solution of vinyl ester=50 / 15 / 20 / 15 (weight ratio) ("VEOVA9": trade name manufactured by Japan Epoxy Resin Co., Ltd., vinyl ester of branched chain fatty acid, solvent is toluene / n-propanol=70 / 30 weight ratio mixed solvent, non-volatile content about 50%), about 7.4 parts of sorbitan polyglycidyl ether with an epoxy equivalent of 170, about 0.6 part of diazabicyclooctane, about 1 part of TINUVIN 900 (manufactured by Ciba Specialty Chemicals Inc., benzotriazole UV absorber), about 1 part of TINUVIN 292 (manufactured by Ciba Specialty Chemicals Inc., hindered amine light stabilizer) resin composition coated on the polyester film , and heat-dried at about 140° C. for about 10 minutes to make a dry film thickness of about 20 μm to obtain a surface resin layer 1 . Then, on the...

Embodiment 2

[0168] For example figure 2 When preparing the resin composition for the surface resin layer 1 shown, FLUONATE K-703 (manufactured by Dainippon Ink Chemical Industry Co., Ltd., weight average molecular weight 40000, solid component hydroxyl value 72, non-volatile component about 60%) was used. BURNOCK DN-950 is used as hardener and TINUVIN 292 is used as antioxidant. In Example 2, the mixing ratio of the resin composition for the surface resin layer 1 is about 100 parts for FLUONATE K-703, about 25 parts for BURNOCK DN-950, about 1 part for TINUVIN 900, and about 1 part for TINUVIN 292 . Then, the aforementioned composition was coated on a polyester film, and heated and dried at about 140° C. for about 10 minutes to obtain a dry film thickness of about 20 μm to obtain a surface resin layer 1 . Then use polycarbonate non-yellowing type polyurethane resin NY-331 (manufactured by Dainippon Ink Chemical Industry Co., Ltd., about 25% of non-volatile components, solvent DMF, abou...

Abstract

A laminate for printing for coloring a resin layer by allowing a sublimable dyeing agent to permeate into the inside of the resin layer through heating, which comprises, in the order from the surface, a surface resin layer A (1) having a weak affinity with the sublimable dyeing agent and allowing the dyeing agent to pass through it and a coloring resin layer B (12) having strong affinity with the dyeing agent and preventing the transfer of the dyeing agent; and a printing method and a printed matter using the laminate. The laminate for printing has, formed as an inner layer, a coloring resin layer having strong affinity with a sublimable dyeing agent and capable of preventing the transfer of the dyeing agent, which allows the prevention of the transfer of a sublimable dyeing agent having been printed.

Description

technical field [0001] The present invention relates to a printing laminate used in a sublimation dyeing method in which a sublimation dye is penetrated into a resin by heating, a printing method and a printed matter using the laminate. More specifically, it relates to a printing laminate capable of preventing migration of a sublimable dye during dyeing and over time after dyeing, and a printing method and printed matter using the same. Background technique [0002] Currently, when printing an image or the like using a sublimation dye in a printing laminate, once the ink containing the sublimation dye is printed on paper, the printed surface of the paper is bonded to the surface of the printing laminate. , using a vacuum heating press and a hot roller, etc., to make the printing surface of the paper and the printing laminate closely bonded, and to make the thermal compression bond so that the sublimable dye penetrates into the inside of the printing laminate. As another met...
