COMPOSITE MATERIAL, PHOTOSENSITIVE RESIN COMPOSITION FOR SOLDER RESIST, AND PHOTOSENSITIVE ELEMENT

摘要

Disclosed is a composite material provided with a metal material and a protective member which is a cured curable resin composition provided on a surface of the metal material. The curable resin composition contains radical-polymerizable monomers including a first monofunctional radical-polymerizable monomer and a second monofunctional radical-polymerizable monomer. The first monofunctional radical-polymerizable monomer is a monomer for forming a homopolymer having a glass transition temperature of 20°C or lower when polymerized independently. The second monofunctional radical-polymerizable monomer is a monomer for forming a homopolymer having a glass transition temperature of 50°C or above when polymerized independently.
