초록

A highly bulked kaolin pigment is prepared by mixing a small but effective amount of a water-soluble cationic polyelectrolyte flocculant with a kaolin clay pigment in the presence of water to prepare a bulked clay pigment product. Upon dewatering, the resultant polyelectrolyte treated clay product can be dispersed to form high solids clay-water slurries useful in making aqueous coating colors suitable for manufacturing coating lightweight publication papers or the pigment can be used as a filler for paper webs.

청구항

A novel opacifying pigment composition consisting essentially of particles of hydrous kaolin clay flocculated with a minor amount of a cationic polyelectrolyte flocculant, said particles of clay having a particle size distribution such that less than 35% by weight are finer than 0.3 micrometers prior to being flocculated, said pigment having a G.E. brightness of at least 85%, and scattering values at 457 nm and 577 nm higher than that of said clay in the absence of said polyelectrolyte, said pigment being capable of being formed into a 62% solids fluid s...
