Title:
PHOTOPOLYMERIZABLE COMPOSITION
Document Type and Number:
Japanese Patent JPH02113002
Kind Code:
A
Abstract:
PURPOSE:To obtain the subject composition having a high sensitivity to active rays within a wide region from ultraviolet to visible rays by blending a polymerizable compound containing an addition polymerizable unsaturated bond with specific two kinds of photopolymerization initiators. CONSTITUTION:The objective composition obtained by adding (B) a compound expressed by formula I [R<1> to R<4> are (substituted) alkyl, (substituted) aryl, etc., provided that at least one of the R<1> to R<4> is alkyl; Z<+> is alkaline metal cation or quaternary ammonium cation] and (C) a compound expressed by formula II [R<1> and R<2> are H or alkyl; R<3> is H or (substituted) alkyl] together as a photopolymerization initiator to (A) a polymerizable compound having an addition polymerizable unsaturated bond. Furthermore, e.g., compounds expressed by formula III, are cited as the component (B) and, e.g., riboflavin, etc., are used as the component (C).
