Patent ID: 7863370

Claim:
A dispersion powder stabilized by a protective colloid, wherein the protective colloid comprises: a) at least one polyvinyl alcohol having a HÃ¶ppler viscosity Î¼ 1 of not more than 3 mPas, the at least one polyvinyl alcohol having a HÃ¶ppler viscosity Î¼ 1 of not more than 3 mPas having a degree of hydrolysis from 80 to 95% and being present in an amount from 10.0 to 50.0% by weight based on the total weight of protective colloid, b) at least one polyvinyl alcohol having a HÃ¶ppler viscosity Î¼ 2 of from 4 mPas to 25 mPas, the at least one polyvinyl alcohol having a HÃ¶ppler viscosity Î¼ 2 of from 4 mPas to 25 mPas having a degree of hydrolysis from 80 to 95% and being present in an amount from 1.0 to 5.0% by weight based on the total weight of protective colloid, wherein the weighted HÃ¶ppler viscosity Î¼ w of the protective colloid is not more than 6 mPas.
