RESIN COMPOSITION FOR LASER PROCESSING

摘要

A resin composition for laser processing which is able to enhance laser processability with maintaining a resist performance of a resin after ultraviolet laser processing, and which can be, for example, used as a resist in forming a circuit of a printed wiring board is provided. Disclosed is a resin composition for laser processing containing a resin and an ultraviolet absorber, wherein the resin is a thermoplastic resin having a carboxyl group and having a softening temperature of from 70 to 140°C, and a content of the ultraviolet absorber is from 1 to 30 parts by mass based on 100 parts by mass of the thermoplastic resin.
