The purpose of the present invention is to provide a photosensitive composition having excellent curability even when a colorant or other substance for attenuating or blocking radiated light is present at a high concentration, the film thickness thereof is large, and the light source is visible-to-infrared light, particularly infrared light having low energy. The present invention is a photosensitive composition characterized by containing as essential components (A) an onium salt represented by general formula (1), (B) a sensitizer, and (C) a radical polymerizable compound. (In formula (1), Rf each independently represents a C1-8 alkyl group, a C2-8 alkenyl group, or a C6-10 aryl group, 80% or more of hydrogen atoms bonded to the carbon atoms of each group being substituted with fluorine atoms, n represents an integer of 1 to 5, and A+ represents a monovalent onium cation.)
本发明的目的是提供一种光敏组合物,即使在高浓度存在
着色剂或其他用于衰减或阻挡辐射光的物质,其膜厚较大,光源为可见光至红外光,特别是能量较低的红外光的情况下,该组合物仍具有优异的固化性。本发明是一种光敏组合物,其特征是含有以下基本成分:(A) 通式 (1) 所代表的鎓盐,(B) 增感剂,(C) 可自由基聚合的化合物。(在式(1)中,Rf各自独立地代表C1-8烷基、C2-8烯基或C6-10芳基,与每个基团的碳原子结合的80%或更多的氢原子被
氟原子取代,n代表1至5的整数,A+代表一价鎓阳离子)。
