A light-sensitive composition comprises a photo-crosslinkable polymer having a photo-dimerizable unsaturated bond and a sensitizer represented by the following general formula (I):
wherein R₁ and R₂ each independently represents a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heterocyclic group or a substituted or unsubstituted allyl group, provided that R₁ and R₂ may form a ring together with the carbon atoms to which they are attached; n represents 0, 1 or 2; and G₁ and G₂ each independently represents a hydrogen atom, a cyano group, a substituted or unsubstituted alkoxycarbonyl group, a substituted or unsubstituted aryloxycarbonyl group, a substituted or unsubstituted acyl group, a substituted or unsubstituted arylcarbonyl group, an alkylthio group, an arylthio group, an alkylsulfonyl group, an arylsulfonyl group or a fluoroalkylsulfonyl group, provided that G₁ and G₂ do not represent a hydrogen atom simultaneously and that G₁ and G₂ may form a ring comprising a non-metallic atom and the carbon atoms to which they are attached. According to the present invention, the sensitivity of the light-sensitive composition is greatly improved by the use of the above sensitizer.
一种光敏组合物包括具有可光二聚的不饱和键的可光交联聚合物和由以下通式 (I) 代表的敏化剂:
其中 R₁ 和 R₂ 各自独立地代表氢原子、取代或未取代的烷基、取代或未取代的芳基、取代或未取代的杂环基团或取代或未取代的烯丙基,条件是 R₁ 和 R₂ 可与它们所连接的碳原子一起形成环;n 代表 0、1 或 2;G₁和 G₂ 各自独立地代表氢原子、氰基、取代或未取代的烷氧羰基、取代或未取代的芳氧羰基、取代或未取代的酰基、取代或未取代的芳羰基、烷硫基烷硫基、芳硫基、烷基磺酰基、芳基磺酰基或氟烷基磺酰基,条件是 G₁ 和 G₂ 不同时代表一个氢原子,并且 G₁ 和 G₂ 可以形成一个由非金属原子和它们所连接的碳原子组成的环。根据本发明,使用上述敏化剂可大大提高光敏组合物的灵敏度。
