摘要

PROBLEM TO BE SOLVED: To provide a curable imide resin having active energy ray curability and capable of forming a resin film having excellent flexibility, a curable resin composition containing the curable imide resin, a cured product thereof, and a production method thereof. I will provide a. The curable imide resin of the present invention is curable by irradiation with active energy rays, and has an imide resin (a) having a divalent chain group and two or more carboxylic acid anhydride groups, and It is characterized in that a reactive compound (b) having a reactive group capable of reacting with a carboxylic acid anhydride group and an ethylenically unsaturated group is reacted as an essential raw material. The imide resin (a) has a hydroxyl group-containing compound (a1) having a chain group and two or more hydroxyl groups and having a number average molecular weight of 200 to 5,000, and an isocyanate compound having two or more isocyanate groups ( It is preferable to react a2) with the acid anhydride group-containing compound (a3) having two or more carboxylic acid anhydride groups as an essential raw material.
