SOLDER RESIST COMPOSITION, COATING FILM, COATED PRINTED WIRING BOARD, PRODUCTION METHOD OF COATING FILM, AND METHOD FOR MANUFACTURING COATED PRINTED WIRING BOARD

摘要

PROBLEM TO BE SOLVED: To provide a solder resist composition allowing production of a green coating film excellent in coating film characteristics, in which a mark with excellent visibility can be imparted even in a single layer of the film, by partially varying a quantity of exposure light during exposure.;SOLUTION: The solder resist composition comprises: a carboxyl group-containing resin (A), at least one photopolymerizable compound (B) selected from the group consisting of a photopolymerizable monomer and a photopolymerizable prepolymer, a photopolymerization initiator (C), a crystalline epoxy compound (D) having a melting point of 130°C or higher, and a colorant (E). The crystalline epoxy compound (D) is dispersed as solid particles. The colorant (D) comprises a blue colorant (E1) and a yellow colorant (E2). The solder resist composition gives a green coating film.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2017,JPO&INPIT
