Provided is a photosensitive composition which can be cured with low energy consumption, even when a substance (such as a colorant) that attenuates or shades an illumination light is contained in a high concentration or even when the photosensitive composition is in the form of a thick film. Specifically provided is a photosensitive composition which comprises the following four components: (1) a radical initiator (A); (2) an acid generator (B) or a base generator (C); (3) a polymerizable substance (D); and (4) a colorant (E), a metal oxide powder (F), or a metal powder (G). Further, the photosensitive composition is characterized in that the radical initiator (A), the acid generator (B), and/or the base generator (C) generates an active species (H) through irradiation with an active ray of light; the active species (H) reacts the radical initiator (A), the acid generator (B), or the base generator (C) to form another species (I); and thus the polymerization of the polymerizable substance (D) by means of the active species (I) proceeds, said active species (H) or (I) being an acid or a base.
提供的是一种光敏组合物,即使含有高浓度的能够衰减或遮蔽照明光的物质(如颜料),或者即使光敏组合物呈现为厚膜形式,也能够以低能耗进行固化。具体而言,提供的光敏组合物包括以下四个组分:(1)自由基引发剂(A);(2)酸发生剂(B)或碱发生剂(C);(3)可聚合物质(D);以及(4)颜料(E)、金属氧化物粉末(F)或金属粉末(G)。此外,光敏组合物的特点在于,自由基引发剂(A)、酸发生剂(B)和/或碱发生剂(C)通过活性光线的照射生成活性物质(H);活性物质(H)与自由基引发剂(A)、酸发生剂(B)或碱发生剂(C)反应形成另一种物质(I);因此,通过活性物质(I)对可聚合物质(D)进行聚合,所述活性物质(H)或(I)为酸或碱。
