ABSTRACT:
A light-sensitive composition is described, containing: (A) a light-sensitive diazo compound, (B) a combination of Polymer (B-1) and Polymer (B-2), and (C) an epoxy resin. Polymer (B-1) is a polymer having the structural units of the general formulae (i), (ii) and (iii). Polymer (B-2) is a polymer having the structural units of the general formulae (iv), (v) and (vi). ##STR1## wherein R.sup.1 is a hydrogen atom or a methyl group, R.sup.2 is an unsubstituted or substituted benzyl group, a lower alkyl group, or a halogen-substituted lower alkyl group, R.sup.3 is a hydrogen atom, a lower alkyl group, or a halogen-substituted lower alkyl group, R.sup.4 is a tert- or iso-butyl group, and R.sup.5 is a lower alkyl group. This composition is a negative-type light-sensitive composition and is used to prepare a lithographic printing plate, for example. This printing plate is superior in lipophilic nature and also in mechanical properties such as abrasion resistance.
