ABSTRACT:
Dispersion powders stabilized include a protective colloid. The protective colloid includes at least one polyvinyl alcohol having a Höppler viscosity μ1of not more than 3 mPas and at least one polyvinyl alcohol having a Höppler viscosity μ2of from 4 mPas to 25 mPas. The weighted Höppler viscosity μwof the protective colloid is not more than 6 mPas.
