Abstract
The invention pertains to a printing form and a process for preparing the printing form from a solvent-free curable composition that includes, in prescribed relative amounts, an epoxy novolac resin; a bisphenol-A epoxy resin or a bisphenol-F epoxy resin; a monofunctional reactive diluent; a multifunctional reactive diluent; and a stoichiometric amount of an amine curing agent. The ratio of the epoxy novolac resin to the bisphenol epoxy resin is 1:3 to 3:1 by weight. The process includes applying the curable composition to a supporting substrate to form a layer, curing the layer at one or more temperatures in a temperature range, and engraving to form at least one cell in the cured layer. The process prepares printing forms, particularly gravure printing forms, having a cured resin composition layer that is engravable, resistant to solvent inks and to mechanical wear, and capable of printing gravure-quality images.
