Abstract

Una placa de impresión litográfica fotosensible positiva que puede hacerse funcionar bajo luz blanca que contiene luz ultravioleta, comprendiendo dicha placa de impresión sobre un soporte una composición fotosensible positiva que muestra, tras exposición por escaneado a la luz en el intervalo de longitud de onda de 650 a 1300 nm, mediante un cambio distinto a un cambio químico, una diferencia en solubilidad en un revelador de álcali entre una porción expuesta y una porción no expuesta, caracterizada porque dicha composición comprende: (i) un colorante que absorbe dicha luz, (ii) una resina soluble en álcali y (iii) un agente que suprime solubilidad que es capaz de rebajar la disolución en un revelador alcalino de una mezcla que comprende el colorante y la resina soluble en álcali, con la condición de que el agente que suprime solubilidad no se seleccione entre el grupo constituido por un compuesto de quinolinio, un compuesto de benzotiazolio, un compuesto de piridinio ni un compuesto de imidazolina.

Claims (10)
