摘要： A method of making a negative-working heat-sensitive lithographic printing plate precursor is disclosed, the method comprising the steps of (a) preparing an aqueous dispersion comprising particles of a hydrophobic thermoplastic polymer A which is not soluble or swellable in an aqueous alkaline developer and particles of a polymer B which is soluble or swellable in an aqueous alkaline developer but not soluble or swellable in water, wherein the glass transition temperature of polymer A is higher than the softening temperature of polymer B; (b) applying the aqueous dispersion on a lithographic substrate having a hydrophilic surface, thereby obtaining an image-recording layer; (c) overall heating the image-recording layer at a temperature which is higher than the softening temperature of polymer B without inducing coalescense of the particles of polymer A. The printing plate precursor has improved mechanical resistance.
