Title (EN) DESENSITIZING SOLUTION AND PROCESS FOR TREATING A DIAZO PHOTOSENSITIVE PRINTING PLATE
(FR) SOLUTION DESENSIBILISANTE ET PROCEDE POUR LE TRAITEMENT D"UNE PLAQUE D"IMPRESSION DIAZO PHOTOSENSIBLE
Abstract: front page image
(EN)A desensitizing solution and process For using the solution are disclosed to desensitize a diazo photosensitive printing plate after development. The solution comprises a water soluble desensitizing agent having the formula (FORMULA) where Y is an acid group or a water soluble salt of said acid group and wherein R is another Y, hydrogen, an aliphatic hydrocarbon or an aromatic hydrocarbon which reacts with any residual photosensitive diazo on the developed plate to render the diazo incapable of forming an oleophilic substance and a filming agent selected from water soluble aliphatic polyols have less than eight carbon units, the acid derived monoesters of these polyols, and the alkali metal salts of the monoesters.
(FR)La solution desensibilisante et le procede d"utilisation de la solution servent a desensibiliser une plaque d"impression diazo photosensible apres developpement. La solution comprend un agent desensibilisant, soluble dans l"eau, de formule: (FORMULE) dans laquelle Y est un groupe acide ou un sel de l"acide correspondant, soluble dans l"eau et R est Y ou represente l"hydrogene, un hydrocarbure aliphatique ou un hydrocarbure aromatique qui reagit avec n"importe quel diazo sur la plaque developpee pour l"empecher de former une substance oleophile et un agent filmogene choisi parmi les polyols aliphatiques hydrosolubles ayant moins de 8 atomes de carbone, les monoesters de ces polyols et les sels de metaux alcalins de ces monoesters.
