Abstract
According to the present invention there is provided a heat-sensitive material for making lithographic printing plates having on a lithographic support an image-forming layer including a hydrophilic binder, a cross-linking agent for the hydrophilic binder, metal oxide particles with a mean diameter of at least 100 nm and dispersed hydrophobic thermoplastic polymer particles, characterized in that the image-forming layer has a ratio of specific surface (in m.sup.2 per g) over mean roughness(in .mu.m) of more than 0.65 and that the mean pore width is less than 15 nm.
