Disclosed are photo sensitizers 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—R1 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.
揭示了包括聚醇基团与融合芳香基团共价键合的光敏化剂。还公开了一种改善涂层(如阳离子紫外光固化涂层)的紫外激光烧蚀性能的方法,通过将含草酸酰基添加剂纳入阳离子紫外光固化或其他涂层中。还公开了具有公式Q-O—C(O)—C(O)—O—R1的含草酸酰基敏化剂,其中Q代表融合芳香基团,R1是烷基或芳基,还公开了含草酸酰基氧杂环戊烷树脂、含草酸酰基聚酯聚醇和包括含草酸酰基添加剂的阳离子紫外光固化涂层配方。
