Abstract

[PROBLEMS] To provide a resin composition which can be cured with an active energy ray such as ultraviolet ray or the like and enables to produce a rigid film or a molding material. [MEANS FOR SOLVING PROBLEMS] Disclosed is a reactive compound derived from a phenolic epoxy resin containing a specific structure in the molecule, a compound having both of at least one polymerizable ethylenically unsaturated group and at least one carboxyl group in the molecule, and a compound having both of at least one hydroxyl group and at least one carboxyl group in the molecule. Also disclosed is a curable resin composition utilizing the reactive compound. A rigid cured article can be produced from the curable resin composition. The reactive compound has a good pigment-dispersing property.

Description

technical field [0001] The present invention relates to a reactive epoxy carboxylate compound (A) and a reactive polycarboxylic acid compound (B) as its acid modified product. The reactive epoxy carboxylate compound (A) is represented by acrylic acid or the like. The compound (b) having more than one ethylenically unsaturated group capable of polymerizing and more than one carboxyl group in the molecule and the compound (c) having more than one hydroxyl group and more than one carboxyl group in the molecule and the compound containing a specific structure in the molecule It is obtained by reaction of phenolic epoxy resin (a). These reactive epoxy carboxylate compounds (A) and reactive polyvalent carboxylic acid compounds (B) have good affinity with pigments, and tough cured products can be obtained from resin compositions containing these compounds. Background technique [0002] For the purpose of reducing the size and weight of portable devices and improving the communicat...
