Title
(EN) ON-PRESS DEVELOPABLE PRINTING PLATES WITH HYDROGEN BOND FORMING DEVELOPABILITY STABILIZER
(FR) PLANCHE D'IMPRESSION DEVELOPPABLE SUR PRESSE, ASSOCIEE A UN STABILISATEUR DE DEVELOPPEMENT CAPABLE DE FORMER DES LIAISONS HYDROGENE
Abstract
(EN)
The present invention discloses a lithographic printing plate developable on a lithographic printing press equipped with means for delivering lithographic ink and aqueous fountain solutions to the printing plate, the lithographic printing plate having in order (a) a printing plate substrate; and (b) a photoresist photohardenable upon imagewise exposure to actinic radiation, the photoresist comprising (i) a macromolecular organic binder; (ii) a photopolymerizable ethylenically unsaturated monomer having at least one terminal ethylenic group capable of forming a high polymer by chain-propagated polymerization, (iii) a polymerization initiator activable by actinic radiation, and (iv) an amphoteric hydrogen bond-forming developability stabilizer, the hydrogen bond-forming developability stabilizer being non-volatile miscible in the photoresist and soluble in said lithographic ink and fountain solutions; the amphoteric hydrogen bond-forming developability stabilizer possessing a strong hydrogen bond-forming functional group with the remainder of the molecule manifesting hydrophilicity.
(FR)
La présente invention se rapporte à une planche d'impression lithographique développable sur une presse à impression lithographique équipée d'un organe d'alimentation de la planche d'impression en encre lithographique et en solutions de mouillage aqueuses, ladite planche d'impression lithographique comportant, par ordre, (a) un substrat de planche d'impression et (b) une photorésine photodurcissable par exposition globale de l'image à un rayonnement actinique, la photorésine comportant (i) un liant organique macromoléculaire, (ii) un monomère photopolymérisable éthyléniquement insaturé ayant au moins un groupe éthylène terminal capable de former un haut polymère par polymérisation à propagation en chaîne, (iii) un amorceur de polymérisation activable par rayonnement actinique et (iv) un stabilisateur de développement amphotère capable de former des liaisons hydrogène qui est non volatil, miscible dans la photorésine et soluble dans ladite encre lithographique et les solutions de mouillage, ledit stabilisateur de développement amphotère capable de former des liaisons hydrogène possédant un fort groupe fonctionnel capable de former des liaisons hydrogène et le reste de la molécule manifestant une certaine hydrophilie.
