Abstract
A process for coating drug forms by application of an aqueous dispersion which contains as binder a redispersed latex of an emulsion polymer onto the drug form and evaporating the water at a temperature at which the latex particles form a film, comprises employing a polymer dispersion which has been prepared by emulsion polymerization of one part by weight of at least one ethylenically unsaturated polymerizable monomer, by means of initiators which provide free radicals, in the presence of from 0.1 to 2 parts by weight of saccharified starch, and from 0 to 5% by weight, based on the monomer or monomers, of a surfactant, with or without further conventional additives, drying to a powder and redispersing in water.
