ABSTRACT:
A coating mix for the production of coated paper and board is described in form of an aqueous dispersion with a solids content of 50 to 80% consisting of pigments, binders, and additives. The coating mix exhibits thixotropic flow characteristics and is characterized by the usage of special amine-group or amide-group containing polymers, which act as protective colloids for the pigment particles. The coating mix contains preferably between 0.1 to 1 weight percent of a grafted gelatin.
