Embodiment Construction

[0073] Next, the present invention will be described more specifically with reference to experimental examples. In addition, unless otherwise specified in this specification, "part" and "%" are a mass basis. Table 1 shows the coating film compositions and evaluation results of Examples and Comparative Examples.

[0074] (Preparation of Hard Coat Composition (1))

[0075] 60 parts of acrylic acrylate resin (WHV-652: produced by DIC company), 10 parts of urethane acrylate resin (Unidic V-4000BA: produced by DIC company), polymerization initiator (Yanjiagu 184: Ciba Specialty Chemicals) 3 parts prepared by the company) and 27 parts of methyl ethyl ketone were mixed and stirred with a mixer to make the hard coating composition (1).

[0076] Here, WHV-652 produced by DIC Company has an acrylic acid double bond equivalent of 200-2500g / eq, a weight-average molecular weight of 50000-250000, a glass transition temperature of 40-130°C, and a hydroxyl value of 5-300 (mgKOH / g). An acti...

Abstract

The invention provides a transfer sheet for active energy ray curing intra-mold forming and a manufacture method thereof, wherein the transfer sheet has excellent adhesion resistance and sealing performance and heat resistance during forming. The transfer sheet for active energy ray curing intra-mold forming is characterized in that primer agent composites are used for half-curing, wherein the primer agent composites contain active energy ray curing crylic acid acrylic ester resin with hydroxyl and (methyl) acryloyl groups and / or active energy ray curing carbamic acid ester acrylic ester resin and polyisocyanate compounds; or active energy ray curing crylic acid acrylic ester resin and / or active energy ray curing carbamic acid ester acrylic ester resin curing hard coating and / or curing primer coating are used for half curing.

Description

technical field [0001] The present invention relates to an active energy ray-curable transfer sheet for in-mold molding (hereinafter referred to as a transfer sheet) having a hard coat layer and a primer layer excellent in blocking resistance, adhesiveness, heat resistance during molding, and formability. Sheet). Background technique [0002] On the surface of substrates such as paper, wood, plastic, metal, glass, inorganic materials, etc., it is carried out to protect the surface by imparting various properties such as hardness, scratch resistance, friction resistance, chemical resistance, and organic solvent resistance. coating. As a coating agent, what consists mainly of an active energy ray-curable composition is used in many cases. This is because the scratch resistance and friction resistance of the surface are more excellent than the case of using a thermoplastic resin or a thermosetting resin. [0003] For the purpose of protecting the surface of plastic molded ar...
