POLYOL PHOTOSENSITIZERS, CARRIER GAS UV LASER ABLATION SENSITIZERS, AND OTHER ADDITIVES AND METHODS FOR MAKING AND USING SAME

摘要

Disclosed are photosensitizers that include a polyol moiety covalently bonded to a fused aromatic moiety. Also disclosed is a method for improving UV laser ablation performance of a coating, such as a cationic UV curable coating, by incorporating an oxalyl- containing additive into the cationic UV curable or other coating. Oxalyl -containing sensitizers having the formula Q-O-C(O)- C(O) -O-R^1, wherein Q represents a fused aromatic moiety and R¹ is an alkyl or aryl group, are also disclosed, as are oxalyl -containing oxetane resins, oxalyl -containing polyester polyols, and cationic UV curable coating formulations that include oxalyl -containing additives.
