Abstract

A light-sensitive resin composition which can be developed in an alkaline aqueous solution and has an excellent image-forming performance and a sufficient UV absorbance after an image formation is disclosed. The light-sensitive resin composition includes (1) a photopolymerization initiator or a photopolymerization initiator system, (2) an addition-polymerizable monomer having an ethylenically unsaturated double bond, (3) a high molecular binder which is soluble in an alkaline aqueous solution and insoluble in water, and (4) at least one of the compounds which substantially do not absorb light in a specified UV region and which, when subjected to treatment with an aqueous alkali solution and/or to heating, are capable of absorbing light in that region and have substantially no absorption in the visible region.

Claims8

Dependent claims

A light-sensitive resin composition containing:

(1) a photopolymerization initiator or a photopolymerization initiator system,
(2) an addition-polymerizable monomer having an ethylenically unsaturated double bond,
(3) a high molecular weight binder which is soluble in an alkaline aqueous solution and insoluble in water, and
(4) at least one of compounds having absorption in a wavelength region that has been shifted to a shorter wavelength region by converting at least one functional group of a UV absorber into another functional group which is convertible into the original functional group by being subjected to both of (A) treatment with an aqueous alkali solution and (B) heating,
wherein said compounds do not substantially absorb light in a 330-430 nm region after said converting at least one functional group of a UV absorber into another functional group, but after converting said another functional group back into the original functional group are capable of absorbing in that region but not in the visible region.
