Abstract
A light-sensitive composition containing a high molecular compound and a light-sensitive o-naphthoquinonediazide compound is disclosed. The high molecular compound includes a structure unit represented by the general formula (I): ##STR1## wherein R is a hydrogen atom or a methyl group, and Y is a phenylene group, a substituted phenylene group, a naphthylene group or a substituted naphthylene group. The light-sensitive composition makes possible the production of a light-sensitive material which can be developed under a wide range of development conditions to provide a lithographic printing plate having high printing durability.
