Abstract
According to the present invention there is provided a heat-sensitive material for making a negative working non-ablative lithographic printing plate including in a heat sensitive layer thermoplastic polymer beads and a compound capable of converting light into heat on a surface of a hydrophilic metal support, the layer being free of binder, and characterized in that the thermoplastic polymer beads have a diameter between 0.2 μm and 1.4 μm.
Claims7
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 on a grained and anodized aluminum support, said layer being free of binder, wherein said thermoplastic polymer beads have a diameter between 0.2 μm and 1.4 μm and wherein the grained and anodized aluminum support has a center-line average roughness value between 0.2 μm and 1.5 μm.
