Method for making a lithographic printing plate requiring no wet processing |
(57) 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.
