Abstract:
A water-less lithographic plate precursor which comprises on a base material having in one or two layers a light sensitive composition which comprises a polymer selected from a polymer with hydroxy groups, a polyvinyl butyral and an epoxy resin, an acid generator compound which on exposure to radiation generates an acid and a silyl ether of the general formula I: ##STR5## where Rf is a fluoroaliphatic group having 3 to 10 carbon atoms, Y is selected from --O--, --SO.sub.2 --, --CO-- and a direct link, X is selected from --NR.sub.4 where R.sub.4 is hydrogen or lower alkyl having up to six carbon atoms and a direct link, each of R.sub.1, R.sub.2 and R.sub.3 are lower alkyl groups having up to six carbon atoms and R.sub.5 is a lower alkyl group having up to six carbon atoms.
