Abstract:
A visible light-sensitive composition comprising (A) a polymer having carboxyl group(s) and optionally having hydroxyphenyl group(s); (B) a compound having at least two vinyl ether groups per molecule; (C) a compound, which generates an acid when irradiated with a visible light, represented by the general formula (I) ##STR17## wherein R represents ##STR18## group, wherein R.sub.1, R.sub.2 and R.sub.3 each independently represents a hydrogen atom or a fluorine atom, ##STR19## and (D) a sensitizing dye selected from the group consisting of compounds represented by formulae (II) and (III) ##STR20## wherein R.sub.4, R.sub.5, R.sub.6 and R.sub.7 each independently represents methyl, ethyl, propyl or isopropyl groups, and R.sub.8 and R.sub.9 each independently represents a hydrogen atom, an alkyl group of 1-4 carbon atoms, an alkoxy group of 1-4 carbon atoms, an alkoxycarbonyl group of 2-5 carbon atoms, a dialkylamino group having 1-4 carbon atoms in each alkyl moiety, Cl, Br, CN, NO.sub.2 or SO.sub.2 CH.sub.3 ; and ##STR21## wherein R.sub.10, R.sub.11 and R.sub.12 each independently represents methyl, ethyl, propyl or isopropyl groups, and R.sub.13 and R.sub.14 each independently represents a hydrogen atom, an alkyl group of 1-4 carbon atoms, an alkoxy group of 1-4 carbon atoms, an alkoxycarbonyl group of 2-5 carbon atoms, a dialkylamino group having 1-4 carbon atoms in each alkyl moiety, Cl, Br, CN, NO.sub.2 or SO.sub.2 CH.sub.3.
