Abstract
A water-redispersible powder composition comprising (a) 100 parts by weight of a powder consisting of a water-insoluble film-forming polymer prepared from at least one ethylenically unsaturated monomer and at least one monomer selected from monomers having a carboxylic function and acrylamide or methacrylamide, and (b) 2-40 parts by weight and preferably 8-22 parts by weight of at least one amino acid or a salt thereof. A method for preparing said composition and the use thereof are also disclosed.
