ABSTRACT:
The present invention relates to a coating material for producing a porous ink-absorbent coating on a substrate to be used in ink-jet printers, comprising radiation curable material and particulate material in a liquid carrier, wherein the weight ratio of particulate material to radiation curable material is greater than 1:1. Also disclosed is a process for preparing a coated substrate using such a coating material. Advantageously, the coating material of the present invention does not crack upon curing, and conveniently forms a porous coating having a glossy surface, while retaining a porous structure for ink-absorption.
