Abstract
Solid fabric-care preparations showing a tendency towards troublesome interactions, or constituents thereof, are coated by application of dissolved or dispersed organic film-forming polymers soluble in alkaline medium. Suitable polymers contain in particular carboxyl groups and are preferably derived from vinyl esters. The carboxyl groups emanate from copolymerized carboxylic acids which make up from about 2 to 10 mole % of the copolymer. The copolymers are best prepared in the form of finely divided dispersions and optionally contain a protective colloid and/or an emulsifier.
