Embodiment 1

[0092] Mix 27.2 parts of difunctional acrylate (resin 1) containing thioether bond obtained in Synthesis Example 1, 19 parts of pentaerythritol triacrylate (hereinafter, PE3A), 1.9 parts of photopolymerization initiator (trade name "IRGACURE184" BASF company) , 51.8 parts of methyl ethyl ketone (hereinafter, MEK) to prepare an active energy ray-curable hard coat resin composition having a resin component of 40% by weight.

Embodiment 2

[0094]In a four-neck flask equipped with a stirrer, a thermometer, a reflux cooler, a nitrogen flow inlet, and a dropping funnel, add 32.5 parts of methyl isobutyl ketone, heat up to 110°C under a nitrogen flow, and shrink from the methacrylic acid A GMA polymer was obtained by dropping the entire amount of a mixed solution of 32.5 parts of glyceride (hereinafter, GMA) and 1.3 parts of azobisisobutyronitrile into the dropping funnel over 2 hours and reacted for 5 hours. Thereafter, after cooling to normal temperature, 16.5 parts of acrylic acid, 0.4 parts of triphenylphosphine, and 0.1 part of methoquinone were added, the dropping funnel was removed, the nitrogen flow inlet was replaced with an air bubbling device, and the air was stirred while bubbling. It was made to react at 110 degreeC for 6 hours, and the resin liquid (resin 8) of 50 weight% of the resin component of the polyester acrylate of weight average molecular weight 17000 was obtained. With respect to 38.1 parts o...

Embodiment 3

[0096] To 27.2 parts of the thioether bond-containing pentafunctional acrylate (resin 3) obtained in Synthesis Example 3, 19 parts of hexafunctional urethane acrylate (trade name "UA-306H"; Kyoeisha Chemical Co., Ltd.) .9 parts and 51.8 parts of MEK to prepare an active energy ray-curable hard coat resin composition having a resin component of 40% by weight.

Abstract

The present invention is multifunctional thio(meth)acrylate resin, hard coating resin composition, cured film, plastic film and products thereof. The object is to provide a polyfunctional thio(meth)acrylate resin capable of forming a highly flexible cured film having high hardness and scratch resistance, excellent hard coating properties, high elongation and flexibility . The polyfunctional thiol compound (A) whose x calculated from formula 1 is 100 to 500 or less has the (methyl group) at the thiol terminal and at least one terminal of the bifunctional (meth)acrylate compound (B). It is a polyfunctional thio(meth)acrylate resin formed by the reaction of acryloyl group with ene-thiol and having two or more terminal structures represented by the general formula (1).

Description

technical field [0001] The present invention relates to polyfunctional thio(meth)acrylate resins, active energy ray-curable hard coat resin compositions containing the same, cured films thereof, plastic films laminated with cured films, and plastic injection molding using plastic films Molded and processed products. Background technique [0002] As a manufacturing method for decorating the surface of a plastic product with a pattern, texture, etc., or imparting difficulty in damage, (1) laminating an adhesive layer or a pattern layer on a plastic film such as PET (polyethylene terephthalate), In-mold injection molding method (called InMolding Lamination or In Molding Film, etc.) in which a hard coating film for decoration made of a hard coating is inserted into a mold and attached to a plastic molded product at the same time as injection molding. The film lamination decoration method of sticking a hard coating film on the surface of injection-molded plastic products, steel ...
