Title
(EN) SILICATE-FREE DEVELOPER COMPOSITIONS
(FR) COMPOSITIONS DE RÉVÉLATEUR EXEMPTES DE SILICATE
Abstract
(EN)
A silicate-free alkaline aqueous developer composition has a pH of at least 12 and comprises a hydroxide alkali agent, a metal cation M2+ selected from barium, calcium, strontium, and zinc cations, a chelating agent for the metal cation, and an alkali metal salt that is different than the other components. These developer compositions can be used to process imaged positive-working lithographic printing plate precursors to prepare lithographic printing plates.
(FR)
L'invention concerne une composition de révélateur aqueuse alcaline exempte de silicate ayant un pH d'au moins 12 et comprenant un agent alcalin hydroxyde, un cation métallique M2+ sélectionné parmi baryum, calcium, strontium et cations de zinc, un agent chélateur pour le cation métallique et un sel de métal alcalin qui est différent des autres constituants. Ces compositions développantes peuvent être utilisées pour le traitement de précurseurs de plaque d'impression lithographique positive afin de préparer des plaques d'impression lithographiques.
