Abstract

Coating colors having a dextrin having high amylopectin content. When such a dextrin is used in the form of an adhesive, it confers an excellent stability on the adhesive. When the adhesive is subsequently incorporated in the coating color, it makes it possible to adjust the Brookfield viscosity thereof, while providing a good compromise between water retention and rheological behavior at high shear gradient. Also, the use of such dextrin for the manufacture of a coating color. Further, a process for the manufacture of a paper or of a cardboard coated on at least one its face with a coating color, and papers and cardboards thus obtained.
