Reactive epoxy carboxylate compound and the active energy ray-curable resin composition using the same

摘要

[Problems] The present invention aims to provide a reactive polycarboxylic acid compound and a reactive epoxy carboxylate compound gives a cured product having excellent balance between toughness degradation and less to light. [MEANS FOR SOLVING PROBLEMS] In the general formula (1) (Wherein, R ₁ is the same or different, n is a positive number, respectively from 1 to 6 as an average value m is also an integer of 1 to 4, an alkyl group having 1 to 4 represent a hydrogen atom, a halogen atom or . shown) hydrogenated epoxy resin, the core hydride of aromatic rings of the epoxy resin represented by the formula as (a), a compound having a carboxyl group of one or more ethylenically unsaturated polymerizable groups of the one or more in the molecule (b) reactive polycarboxylic acid compound obtained by reacting a polybasic acid anhydride (c) a reactive epoxy carboxylate compound obtained by the reaction of (A), compound (A) (C), and contain such about the use and active energy ray-curable composition.
