Abstract
A new coated fibrous substrate is produced by applying a coating containing swelled super absorbent particles having a minimum dimension of at least 5 microns to obtain the desired porosity and roughness in the finished coating, applying the coating to the substrate at least partially setting the coating thereafter driving at least the majority of the carrier absorbed by the super absorbent particles from the particles to leave macro-voids in the coating and produce a coated surface having a roughness in the macro as opposed to the micro range.
Claims16
A coated fibrous substrate comprising a fibrous substrate, a coating on at least one surface of said fibrous substrate, said coating being porous and having voids formed therein, said coating forming an exposed coating surface on a side of said coating remote from said one surface, a number of said voids open through said exposed coating surface to enhance printability of said exposed coating surface, a majority of said voids having a size of at least 5 microns and less than 100 microns.
