Abstract
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 MA of less than 500 kDa; between 10% and 70% by weight of dextrin (B) of at least one dextrin having a weight-average molecular weight MB; 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 MB is greater than MA+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.
