PROTECTIVE FILM FOR LASER PROCESSING AND PROCESSING METHOD USING THE SAME

摘要

Disclosed is a protective film for laser processing, which has high adhesiveness and is capable of protecting an object to be processed with a uniform thickness, while being prevented from carbonization/adhesion due to thickness variations. In addition, this protective film for laser processing is free from the problem of waste water contamination when it is removed. Also disclosed is a laser processing method using such a protective film. Specifically disclosed is a protective film for laser processing, which contains a (meth)acrylate copolymer and a radiation-polymerizable (meth)acrylate having an unsaturated bond.
