Novel graft polymers having a polymer backbone (A) as a graft base having polymeric sidechains (B) grafted thereon. The polymeric sidechains (B) are obtainable by polymerization of optionally (B1) at least one vinyl ester monomer, at least one, preferably a least two nitrogen-containing monomer (B2), and optionally further monomer(s) (B3). The polymer backbone (A) comprises polyalkylene-oxide-derived moieties and moieties derived from lactone(s) and/or hydroxy acid(s), those moieties being mixed such that the polymer backbone contains ester-functions within the polymer chains. Process for obtaining such a graft polymer, the process is preferably carried out by free-radical polymerization. Use of such a graft polymer within, for example, fabric and home care products. Compositions and products, such as fabric and home care products, containing such graft polymer. The graft polymers are preferably employed in cleaning compositions as dye transfer inhibitor.
