Abstract
Heat-imagable negative working lithographic printing forms employ negative working heat sensitive compositions comprising a water soluble binder and particles of pigment in association with a thermoplastic resin. Heat causes fusion of the particles to the binder. Heated regions are thereby rendered insoluble to aqueous developers. Unheated areas are soluble in developer or fount solutions, so development may take place "on-press" during the initial phase of a print run.
