ABSTRACT:
A light-sensitive composition comprises a diazo resin, a polymeric binder and a low molecular weight organic compound having at least 3 carboxyl groups and free of other functional groups containing elements other than hydrogen and carbon atoms. The composition may further comprise a compound carrying at least one phosphorus atom-containing oxoacid residue and a compound carrying at least one sulfonic acid residue. The light-sensitive composition can easily be developed with an aqueous alkaline developer, can provide a lithographic printing plate having good printing durability and has excellent storage stability. Therefore, the developability and resistance to background contamination thereof are not deteriorated even after storing under high temperature and humidity conditions over a long time period.
