Abstract
This invention provides a composition and a means being capable of easily recovering the color of faded clothes in home. The composition is a color recovering agent which comprises (a) a water-insoluble polymer with a refractive index of 1.20 to 1.45 at 25° C., (b) a compound or polymer having a molecular weight of 300 to 1,000 having specific groups such as amide group, (c) water and (d) a non-aqueous solvent, wherein the ratio of (a)/(b) by weight is in the range of 3/1 to 100/1.
Claims5
A color-recovering agent composition which comprises (a) a water-insoluble polymer with a refractive index of 1.20 to 1.45 at 25° C., (b) at least one compound selected from the group consisting of components (i) and (ii) below defined and (c) water, wherein the ratio by weight of (a)/(b) is in the range of 3/1 to 100/1:
- (i) a compound with a molecular weight of 300 to 1,000, having, in the molecule thereof, at least one member selected from the group consisting of an amide group, an ester group, a quaternary ammonium group and a tertiary amino group and at least one of a C10-36 alkyl or alkenyl group, and
- (ii) a polymer or copolymer derived from at least one ethylenically unsaturated compound having at least one member selected from the group consisting of an amide group, a carboxylic acid group, a hydroxyl group, a quaternary ammonium group and a tertiary amino group.
