Water-soluble or -dispersible, film-forming graft copolymers obtained by radical polymerization of vinyl esters of 1-24C aliphatic carboxylic acids in presence of polyethers of average mol. wt. (Mn) /-300 are used as (i) coatings for particulate detergents or cleaning agents or (ii) as packaging for detergents, cleaning agents or post-wash treatment agents to give portions of the type used together with the packaging. Water-soluble or -dispersible, film-forming graft copolymers obtained by radical polymerization of vinyl esters of 1-24C aliphatic carboxylic acids in presence of polyethers of average mol. wt. (Mn) /-300 and of formula (I) are used as (i) coatings for particulate detergents or cleaning agents or (ii) as packaging for detergents, cleaning agents or post-wash treatment agents to give portions of the type used together with the packaging. R<1> = H, NH2, 1-24C alkyl, R<9>-C(=O)-, R<9>NH-C(=O)- or a polyalcohol residue; R<8> = as for R<1> but not a polyalcohol residue; R<2> - R<7> = -(CH2)2-4-, -CH2CH(Me)-, -CH2CH(CH2Me)- or -CH2-CHOR<10>-CH-2-; R<9> = 1-24C alkyl; R<10> = H, 1-24C alkyl or R<9>-C(=O)-; A = -C(O)O-, -C(O)-B-C(O)O- or -C(O)-NH-B-NH-C(O)O-; B = -(CH2)t- or arylene, optionally substituted; n = 1-8; s = 0-500; t = 1-12; u and x = 1-5,000; and v, w, y and z = 0-5,000.
