Claim:
1. A mixture of at least one polyvinylamine and of at least one liquid composition of cationic starchy materials, in a ratio between 55 to 90 parts by dry weight of polyvinylamine per 10 to 45 parts by dry weight of cationic starchy material, wherein the liquid composition of cationic starchy materials has: a solids content by weight of between 10% and 50%, a viscosity—of greater than 200 mPa·s and at most equal to 350 mPa·s, said viscosity being determined by adjusting the solids content of the liquid composition of cationic starchy material to 10% and then measuring the Brookfield viscosity at 25° C. and at 20 rpm, a total nitrogen content at least equal to 0.6% and at most equal to 1.6%, these percentages being expressed by dry weight relative to the dry weight of composition, a pH below 9, and wherein said cationic starchy material is obtained by enzymatic hydrolysis.
