Title (EN) AQUEOUS DEVELOPABLE COLOR PROOFING ELEMENTS
(FR) ELEMENTS AQUEUX DEVELOPPABLES POUR ESSAIS-COULEURS
Abstract:
(EN) Water coatable and water developable negative-acting color proofing single sheet and overlay systems are described. The water-soluble photosensitive color layer employed in each type of proofing construction includes a photopolymerizable polymer having a weight-average molecular weight between 5,000 and 100,000; an alkaline soluble resin having a weight-average molecular weight between 1,000 and 200,000 and an acid number between 50 and 300; and a water-soluble photoinitiator.
(FR) La présente invention concerne des feuilles seules et des systèmes superposables d'essais-couleurs à négatifs à jaquette d'eau et se développant à l'eau. La couche de couleur photosensible hydrosoluble utilisée pour chaque type de dispositif d'essais-couleurs comporte, non seulement un photo-amorceur hydrosoluble, mais également un polymère photopolymérisable dont la masse moléculaire moyenne en masse se situe entre 5.000 et 100.000, ainsi qu'une résine alcaline soluble dont la masse moléculaire moyenne en masse se situe entre 1.000 et 200.000, pour un indice d'acidité compris entre 50 et 300.
