Abstract:
An imaging element comprising (i) on a hydrophilic surface of a lithographic base an image forming layer comprising dispersed in a hydrophilic binder hydrophobic thermoplastic polymer particles, a cross-linking agent capable of cross-linking said hydrophilic binder upon heating in a ratio between 1:100 and 200:1 by weight versus the hydrophilic binder and (ii) a compound capable of converting light to heat, said compound being comprised in said image forming layer or a layer adjacent thereto wherein said hydrophilic binder is a compound selected from the group consisting of polyvinylalcohol, dimethylhydantoine-formaldehyde resin, a poly(meth)acrylamide, a polyhydroxy-ethyl(meth)acrylate, a polyvinylmethylether, a gelatin and a polysacharide and wherein said image forming layer further comprises a catalyst capable of catalyzing said cross-linking agent or a precursor of said catalyst that can be converted to a catalyst upon heating.
