Transparent resin composition, dry film, cured product, and electronic component

Abstract

The present invention provides a technology related to a transparent resin composition which is excellent in transparency, developability, and adhesiveness. A mode of the present invention is a transparent resin composition. The transparent resin composition comprises: an alkali-soluble polymer (A) and a carboxyl group-containing urethane resin (B) and a polymerizable compound (C). The alkali-soluble polymer (A) contains a cyclohexyl group and a carboxyl group. The carboxyl group-containing urethane resin (B) is obtained using a compound having an isocyanate group not directly connected to an aromatic ring. The polymerizable compound (C) has an ethylene oxide skeleton. In the case where the alkali-soluble polymer (A) and the carboxyl group-containing urethane resin (B) are 100 parts by mass in total, the content of the alkali-soluble polymer (A) is 45 to 75 parts by mass in terms of solid content.
