Method for making a negative working, heat-sensitive lithographic printing plate precursor. |
(57) A method for making a heat-sensitive negative-working lithographic printing plate
precursor is disclosed comprising the steps of
(i) preparing a coating solution comprising hydrophobic thermoplastic polymer particles
and a hydrophilic binder;
(ii) applying said coating solution on a support having a hydrophilic surface or which
is provided with a hydrophilic layer, thereby obtaining an image-recording layer;
(iii) drying said image-recording layer;
characterized in that said hydrophobic thermoplastic polymer particles have an average
particle size in the range from 45 nm to 63 nm,
and that the amount of said hydrophobic thermoplastic polymer particles in the image-recording
layer is at least 70 % by weight relative to the dried image-recording layer.
