<p>PAPER COATING PIGMENTS A pigment for a paper coating composition contains a layer lattice silicate which has a relatively narrow range of particle size distribution compared with pigments of conventional paper coating compositions, and which includes not more than 5%, by weight, of particles which have an equivalent spherical diameter of less than 0.25 microns. Paper coated with a composition including the pigment provides good results when printed by a gravure process.</p> |
