Embodiment

[0590] Hereinafter, the present invention will be described in more detail based on examples. In addition, this invention is not limited to the following Example. It should be noted that the parts herein represent weight.

Synthetic example 1

[0592] Mix 55 parts of ethylene glycol monoacetoacetate monomethacrylate, 66 parts of tert-butyl acrylate, 71 parts of potassium carbonate, 3 parts of 18-crown-6-ether, and 121 parts of tetrahydrofuran, and stir at 50°C for 3 hours . After completion of the reaction, cyclohexane and water were thrown in and washed with water. After the organic layer was neutralized with saturated ammonium chloride aqueous solution, it washed with water twice, and the obtained organic layer was concentrated under reduced pressure, and the monomer A was obtained.

Synthetic example 2

[0594] 55 parts of ethylene glycol monoacetoacetate monomethacrylate, 45 parts of methyl acrylate, 71 parts of potassium carbonate, 3 parts of 18-crown-6-ether, and 100 parts of tetrahydrofuran were mixed, and stirred at 50° C. for 3 hours. After completion of the reaction, cyclohexane and water were thrown in and washed with water. The organic layer was neutralized with saturated ammonium chloride aqueous solution, washed with water twice, and the obtained organic layer was concentrated under reduced pressure to obtain monomer B.

Abstract

The present invention enables the achievement of a resin composition which has both thermosetting properties and active energy ray-curable properties, while achieving good performance. Unlike conventional resin compositions, it is not necessary for this resin composition to worry about a short pot life after blending of a thermal crosslinking agent. Consequently, the resin composition has excellent properties including handling properties, while being obtained at low cost. The curable resin composition is characterized by containing (A) a resin component that contains (a) a (meth)acryloyl group, (b) a hydroxyl group and (c) an alkyl ester group; and (B) an initiator.

Description

technical field [0001] The present invention relates to a curable resin composition, a cured film, a resin-coated molded article, and a multilayer film that use transesterification using a transesterification catalyst and curing by active energy rays as curing reactions. Background technique [0002] The inventors of the present invention have studied a thermosetting resin composition having a transesterification reaction as a curing reaction (Patent Documents 1 and 2). According to a recent study, by using transesterification as a curing reaction, it is possible to secure curing performance equivalent to the generally known curing using a melamine resin or a polyisocyanate compound. [0003] On the other hand, many studies have been conducted on curable compositions that undergo a curing reaction called dual cure. Dual curing is a method of performing two types of curing, namely curing by heat and curing by active energy rays, on the same composition. The application of t...
