A coating slip including at least one pigment, water and: between 30% and 90% by weight of dextrin (A) of at least one dextrin having a weight-average molecular weight Mof less than 500 kDa; between 10% and 70% by weight of dextrin (B) of at least one dextrin having a weight-average molecular weight M; the weight amounts of dextrins being relative to the total amount of the mixture of dextrins (A) and (B) in the composition, characterized in that Mis greater than M+50 kDa. Also, a process for coating paper including a step of coating with this slip, and also to the paper obtained at the end of this process.

Dextrin-based coating slips

A coating slip includes water, at least one pigment and at least one modified starch, exhibiting: a weight-average molecular weight ranging from 250 000 to 2 000 000 Da; and a solubility, measured according to a test A, ranging from 50 to 85%. A process for the preparation of the slip, and a process for coating paper using this slip are also described.
