Abstract (en)

[origin: EP0733487A2] There is provided a method for obtaining a lithographic printing plate requiring no wet processing comprising the steps of image-wise exposing using a laser beam a heat mode recording material comprising on a support a recording composition comprising a hydrophobic polymer and a substance capable of converting the laser beam radiation into heat while said heat mode recording composition is in contact with the acceptor layer of an acceptor element comprising a flexible support, said acceptor layer comprising a hardened non-proteinic hydrophilic polymer obtained by reacting a non-proteinic hydrophilic polymer containing a hydroxyl group or an amino or amido group having a free hydrogen with a hardener capable of reacting with said groups and separating said heat mode recording material from said acceptor material, characterized in that said recording composition comprises a thermal transferable dye which is transferred at the exposed areas from the recording material to the surface of the acceptor element.
