Abstract

L'invention se rapporte à l'impression flexographique. Elle concerne un procédé de post-traitement de plaques d'impression en photopolymère pour flexographie qui contiennent un caoutchouc synthétique comme liant, caractérisé en ce qu'on traite la plaque d'impression, après l'exposition selon une image et le développement, avec une solution d'un isocyanate di- ou poly-fonctionnel dans un solvant qui correspond à l'une des formules suivantes : HO(CH2 -COO)n R ou HO(CH2 -CH2 -O)m R 1 dans lesquelles R est un groupe alcoyle en C4 à C10 ou cycloalcoyle, R1 est un groupe alcoyle en C1 à C6 ou acyle de -CO-CH 3 à -CO- C4 H9 ,n est 0 ou 1 et m va de 1 à 3. Utilisation notamment dans l'impression de matériaux d'emballage.The invention relates to flexographic printing. Disclosed is a method for post-processing flexographic photopolymer printing plates which contain synthetic rubber as a binder, characterized in that the printing plate, after image exposure and development, is treated with a solution of a di- or poly-functional isocyanate in a solvent which corresponds to one of the following formulas: HO (CH2 -COO) n R or HO (CH2 -CH2 -O) m R 1 in which R is a C4 to C10 alkyl or cycloalkyl group, R1 is a C1 to C6 alkyl or acyl group from -CO-CH 3 to -CO- C4 H9, n is 0 or 1 and m ranges from 1 to 3. Use in particular in printing of packaging materials.
