Abstract

[Problem] To provide a curable composition for inkjet printing in which the heat resistance of the obtained coating film is improved as compared with the prior art. [Solution] A curable composition for inkjet printing, comprising (A) a (meth)acrylate having a cyclic skeleton and having an alkylene oxide modification number of 1 or more and 6 or less Monomer; (B1) a bifunctional (meth)acrylate monomer having no cyclic skeleton and two or more alkylene glycol structures; (B2) having no cyclic skeleton and having a monoalkylene and, (C) a photopolymerization initiator. Thereby, the obtained coating film was free from cracks even after assuming the thermal history of many times of welding, was excellent in adhesion to the conductor, and maintained sufficient hardness. In addition, the above-mentioned problems can also be solved by a curable composition for inkjet printing comprising: (A') having a cyclic skeleton and having one or more and 6 (Meth)acrylate monomers with less than or equal to the number of alkylene oxide modifications; (B1') Bifunctional (meth)acrylates having no cyclic skeleton and two or more alkylene glycol structures A monomer; (B2') a bifunctional (meth)acrylate monomer having no cyclic skeleton and having a monoalkylene glycol structure; and, (C') a photopolymerization initiator.

Description

technical field [0001] The present invention relates to a curable composition, in particular to a curable composition that can be used for printing by an ink jet method. Moreover, this invention relates to the hardened|cured material of this curable composition, and the electronic component which has this hardened|cured material. Background technique [0002] Curable compositions used for conventionally known thermosetting, ultraviolet curing, and alkali-developing solder resists contain a high-molecular-weight polymer in the composition in accordance with requirements such as heat resistance. However, when reducing the viscosity of the curable composition for use in ink jet printing, these high molecular weight polymers have high viscosity and may not be used. [0003] Therefore, in recent years, the curable composition used for the solder resist for inkjet printing has designed a composition centering on a low-viscosity monomer. For example, Patent Document 1 discloses a...
