Processless thermal printing plate with well defined nanostructure

摘要

According to the present invention there is provided a heat-sensitive material for making a negative working non-ablative lithographic printing plate comprising in a heat sensitive layer thermoplastic polymer beads and a compound capable of converting light into heat binder on a surface of a hydrophilic metal support, said layer being free of binder, characterized in that said thermoplastic polymer beads have a diameter between 0.2 mu m and 1.4 mu m.
