Patent ID: 8580726

Claim:
A fabric treatment agent comprising a color transfer inhibitor in the form of a polymer obtained from polymerizing benzoxazine monomers compounds, said polymer selected from compounds of the general Formula (I) or from compounds of the general Formula (II) or from mixtures thereof, wherein q is a whole number from 1 to 4, n is a number from 2 to 20 000, R in each repeat unit is selected independently of each other from hydrogen or linear or branched, optionally substituted alkyl groups that comprise 1 to 8 carbon atoms, Z is selected from hydrogen (for q=1), alkyl (for q=1), alkylene (for q=2 to 4), carbonyl (for q=2), oxygen (for q=2), sulfur (for q=2), sulfoxide (for q=2), sulfone (for q=2) and a direct, covalent bond (for q=2), R 1 stands for a covalent bond or a divalent linking group that contains 1 to 100 carbon atoms, R 2 is selected from hydrogen, halogen, alkyl and alkenyl, or R 2 is a divalent group that makes a corresponding naphthoxazine structure from the benzoxazine structure, Y is selected from linear or branched, optionally substituted alkyl groups that contain 1 to 15 carbon atoms, cycloaliphatic groups that optionally comprise one or more heteroatoms, aryl groups that optionally comprise one or more heteroatoms, and —(C═O)R 3 , wherein R 3 is selected from linear or branched, optionally substituted alkyl groups containing 1 to 15 carbon atoms and X—R 4 , wherein X is selected from S, O, and NH and R 4 is selected from linear or branched optionally substituted alkyl groups containing 1 to 15 carbon atoms, c is a whole number from 1 to 4, B is selected from hydrogen (for c=1), alkyl (for c=1), alkylene (for c=2 to 4), carbonyl (for c=2), oxygen (for c=2), sulfur (for c=2), sulfoxide (for c=2), sulfone (for c=2) and a direct, covalent bond (for c=2), A is a hydroxyl group or a nitrogen-containing heterocycle, R 5 is selected from hydrogen, halogen, alkyl and alkenyl, or R 5 is a divalent group that makes a corresponding naphthoxazine structure from the benzoxazine structure and R 6 stands for a covalent bond or is a divalent linking group that contains 1 to 100 carbon atoms, and wherein the agent additionally comprises a polymer of vinyl pyrrolidone, vinylimidazole, or vinylpyridine-N-oxide.
