PAPER AND COATING MEDIUM FOR MULTIFUNCTIONAL PRINTING

A paper coating includes a combination of a primary pigment and a secondary pigment. The primary pigment includes anionic particles having a particle size distribution where at least 96% of the particles by weight have a particle size less than 2 microns. The secondary pigment is a cationic, grit-fr...

Beschreibung
Zusammenfassung:	A paper coating includes a combination of a primary pigment and a secondary pigment. The primary pigment includes anionic particles having a particle size distribution where at least 96% of the particles by weight have a particle size less than 2 microns. The secondary pigment is a cationic, grit-free pigment having an average particle size of 3 microns or less. The coating also includes up to 17 weight % of a hydrophilic styrene-butadiene latex based on the weight of the dry pigments and a co-binder. Another embodiment of this invention is a coated base sheet that includes a base sheet to which the above coating has been applied.
