THERMOSETTING RESIN COMPOSITION FOR LASER BEAM MACHINING, CURED PRODUCT, AND PRINTED WIRING BOARD

摘要

PROBLEM TO BE SOLVED: To provide a thermosetting resin composition for laser beam machining that excels in laser beam machining, and can obtain a cured product having excellent adhesiveness, solvent resistance, and heat resistance.

SOLUTION: The thermosetting resin composition for laser beam machining includes: (A) an epoxy resin that has a polycyclic aromatic hydrocarbon ring; (B) a crosslinkable polyimide resin; (C) a heat-curing catalyst; and (D) an inorganic filler. (B) The crosslinkable polyimide resin desirably includes at least one of a carboxyl group and a phenolic hydroxyl group. Moreover, the mix proportion of (A) the epoxy resin that has a polycyclic aromatic hydrocarbon ring and (B) the crosslinkable polyimide resin is desirably (A):(B) = a proportion from 9:1 to 1:9 by a mass ratio.
