Patent ID: 8853290

Claim:
A photosensitive composition comprising: (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), wherein at least one of the radical initiator (A), the acid generator (B), and the base generator (C) generates an active species (H) on exposure to active rays, the active species (H) reacts with the radical initiator (A), the acid generator (B), or the base generator (C) to generate another active species (I), the active species (I) in turn causes the polymerizable substance (D) to be polymerized, and the active species (H) or (I) is an acid or a base, wherein the active species (H) is different from the active species (I).
