Imaging element comprising a photoacid-sensitive composition and a method for producing lithographic plates therewith

摘要

The present invention provides an imaging element comprising contiguous to a hydrophilic surface of a support a hydrophobic photosensitive composition comprising a photosensitive acid precursor, an acid-sensitive composition which is capable of undergoing polymerization or cross-linking and a hydrophobic binder characterized in that said imaging element comprises one or more protective layers, at least one of the protective layers being contiguous to the hydrophobic photosensitive composition and being a transfer layer which is capable of adhering to a receptor element.
