Abstract
[Problem to be Solved] Provided is a curable composition for inkjet printing, a coating film obtained from which has higher heat resistance than conventional coating films.[Solution] It is a curable composition for inkjet printing, comprising (A) a (meth)acrylate monomer having a cyclic skeleton and having a number of alkylene oxide modifications of one or more and six or less, (B1) a bifunctional (meth)acrylate monomer having no cyclic skeleton and having two or more alkylene glycol structures, (B2) a bifunctional (meth)acrylate monomer having no cyclic skeleton and having a monoalkylene glycol structure, and (C) a photopolymerization initiator. Accordingly, an obtained coating film does not crack, has excellent adhesion to a conductor, and maintains sufficient hardness even after a thermal history that corresponds to a plurality of times of soldering. The above problem to be solved is also solved by a curable composition for inkjet printing, comprising (A′) a (meth) acrylate monomer having a cyclic skeleton and having a number of alkylene oxide modifications of one or more and six or less, (B1′) a bifunctional (meth)acrylate monomer having no cyclic skeleton and having two or mor…
