摘要:
The photosensitive composition of the present invention includes: (1) a radical initiator (A); (2) an acid generator (B) and/or a base generator (C); and (3) a polymerizable substance (D), wherein at least one of the radical initiator (A), the acid generator (B) and the base generator (C) are to generate an active species (H) on exposure to active rays, the active species (H) reacting with the radical initiator (A), the acid generator (B) or the base generator (C) to generate another active species (I), the active species (I) initiating polymerization of the polymerizable substance (D), the active species (H) or (I) is an acid or a base, and the photosensitive composition contains substantially no colorants, metal oxide powder, or metallic powder.
摘要:
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.
