<P>PROBLEM TO BE SOLVED: To provide a photopolymerizable composition capable of satisfying high sensitivity, excellent preservation stability and high printing resistance. <P>SOLUTION: The photopolymerizable composition contains a compound represented by the formula (Q<SP>1</SP>)<SB>k</SB>-R-(Q<SP>2</SP>)<SB>m</SB>wherein Q<SP>1</SP>and Q<SP>2</SP>are each independently a group represented by formula (a) or (b); R is an n-valent hydrocarbon linking group; n equals k+m and is an integer of 2-6; k is an integer of 0-6; and m is an integer of 0-6. In the formulae (a) and (b), Z is H, CH<SB>3</SB>or CHR<SP>b</SP>X<SP>1</SP>; X<SP>1</SP>and X<SP>2</SP>are each independently substituted oxy, substituted amino or substituted thio; R<SP>1</SP>and R<SP>2</SP>are each independently an aliphatic hydrocarbon linking group; and R<SP>a</SP>and R<SP>b</SP>are each independently H or a hydrocarbon group. <P>COPYRIGHT: (C)2004,JPO |
