Abstract
Described are engravable coating compositions, in particular for printing cylinders, which comprise at least one resin capable of undergoing coking and producing only a very small proportion of products which are liquid at the temperature at which it decomposes, the main products of decomposition thereof being solid or gaseous at that temperature; and in general a reinforcing particulate filler having a small proportion of edges having acute projecting angles, said filler generally representing a proportion of from 5 to 75% of the resin+filler volume. The process for coating the cylinders comprises: mixing the resin and the filler and degassing the mixture produced; the coating operation in the true sense and drying the layer or successive layers deposited; and baking the coating.
