Patent

CA 2304106

This invention relates to dye complexing polymers, and, more particularly, to water soluble poly(vinylpyridine betaines) containing a quaternary nitrogen and a carboxylate salt. The polymers herein have effective dye transfer inhibitor (DTI) properties for use, for example, in laundry detergent and fabric softener compositions.

L'invention concerne des polymères de complexion tinctoriale et, plus particulièrement, des poly(vinylpyridine bétaïnes) solubles dans l'eau contenant un azote quaternaire et un sel carboxyle. Lesdits polymères présentent des propriétés effectives d'inhibition de transfert pigmentaire (DTI) et sont utiles, par exemple, dans des compositions de détergent à lessive ou d'assouplissement de tissus.
