Abstract
According to the present invention there is provided a heat mode imaging element comprising in the order given: PA0 i) a lithographic base, PA0 ii) a heat ablatable recording layer and PA0 iii) a top layer having an opposite affinity for ink or an ink abhesive fluid than the lithographic base, characterized in that the top layer comprises as main substance an inorganic-organic composite material wherein the inorganic phase is formed by controlled hydrolysis and polycondensation of a metal alkoxide and the organic phase is an organic polymer or copolymer linked to at least one inorganic atom.
