发明名称 PRINTING FORM AND PROCESS FOR PREPARING THE PRINTING FORM WITH CURABLE COMPOSITION HAVING EPOXY NOVOLAC RESIN
摘要 The invention pertains to a printing form and a process for preparing the printing form from a curable composition that includes an epoxy novolac resin having an epoxide equivalent weight of 156 to 300 g/equivalent, and an amine curing agent selected from primary amines and secondary amines, the agent having an amine equivalent weight of less than or equal to 60 g/equivalent. 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.
