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.
