ABSTRACT:
Structured paper coatings having good opacifying characteristics and good rheological properties are manufactured by a process which consists essentially of mixing a fine particle size kaolin clay pigment; water; at least one material selected from the group consisting of dispersing agents, thickening agents, pH adjusting agents, wetting agents, defoaming agents and mixtures thereof; and at least one cationic flocculant; and then adding a non-cationic binder material to the mixture under continued mixing conditions for a time sufficient to produce the structured paper coating.
