ABSTRACT:
Solubility inhibitors for phenolic resins are disclosed, which when used in phenolic resin/iodonium salt positive printing plate constructions result in significantly increased sensitivity. The solubility inhibitors contain an alkoxyalkyl ester moiety. Also disclosed are presensitized lithogaphic plates containing the solubility inhibitors and a process for developing a photoimage.
