摘要: The invention also relates to a method increase stain resistance and penetration of aqueous coating compositions which comprises providing composition contain at least one pigment, film-forming polymer in the form an dispersion anionic surfactant, wherein surfactant 85 % by weight, preferably 90 more 95 based on total weight ani- onic composition, S, is selected from semi-esters sulfuric acid or phosphoric with alcohol, alcohol carries alkyl radical having 8 30 carbon atoms substituted phenyl has 4 alco- hol may carry oligo-C2-C3-alkylene-ether group provided that number repeat- ing units most 15, salt thereof.
