PRECURSOR DE PLACA DE IMPRESSÃO, LITOGRÁFICA, PROCESSO PARA A PREPARAÇÃO DE MISTURAS DE SENSIBILIZANTES E MÉTODO PARA MANUFATURAR UMA PLACA DE IMPRESSÃO

摘要

A lithographic printing plate precursor comprising an image-recording layer, said image-recording layer being photo-polymerizable upon exposure to actinic light and containing a mixture of sensitizers characterized in that said mixture of sensitizers has in 1-methoxy-2-propanol at 80° C. a solubility of at least 30 wt. %. and preferably a MetaStable Zone Width (MSZW) of at least 8.5° C., said MSZW measured at a cooling and heating rate of 0.2° C./minute.
