WATERFAST INK RECEPTIVE COATINGS FOR INK JET PRINTING, METHODS OF COATING SUBSTRATES UTILIZING SAID COATINGS, AND MATERIALS COATED WITH SAID COATINGS.

摘要

Media coatings for use on substrates for ink jet printing include a cationically modified clay, a cationically modified silica and a binder. Alternatively, the media coatings also include additional additives. The ratio of cationically modified clay to cationically modified silica varies in the coating formulation from about 1 % to about 99 %. Desirably, the ratio of the cationically modified clay to cationically modified silica varies from about 10 % to about 50 %. More desirably, the ratio of cationically modified clay to cationically modified silica varies from about 25 % to about 35 %. The ratio of the total cationically modified clay and cationically modified silica to binder varies from about 20 % to about 80 %. Desirably, the ratio of the total cationically modified clay and cationically modified silica to binder varies from about 65 % to about 75 %.
