Abstract
A light-sensitive planographic printing plate comprising a layer of a photo-polymerizable composition provided on at least one side of a base, wherein said photo-polymerizable composition comprises: PA0 (A) a polymer having at least one group represented by the general formula (I) ##STR1## wherein R.sub.1 to R.sub.5 each represent a member selected from the group consisting of a hydrogen atom, a halgen atom, a carboxyl group, a sulfo group, a nitro group, a cyano group, an amido group, an amino group and a substituted or unsubstituted alkyl group, aryl group, alkoxy gruop, aryloxy group, alkylamino group, arylamino group, alkylsulfonyl group and arylsulfonyl group and Z represents an oxygen atom, a sulfur atom, NH or NR, wherein R represents an alkyl group; and a carboxyl group on the side chain; PA0 (B) a monomer or oligomer having at least two polymerizable ethylenically unsaturated double bonds; PA0 (C) a photo-polymerization initiator, and PA0 (D) a diazo resin.
