Abstract
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.
