Abstract

The color protection properties of detergents when used to wash colored textiles is to be improved. This is substantially achieved in that polymers are used which are molecularly imprinted using dyes.

First claim

What is claimed is:

1. A textile washing detergent with dye transfer-inhibiting properties, comprising:
a.) molecularly imprinted polymers, of ethylenically unsaturated monomers, wherein the molecularly imprinted polymers were obtained by polymerization of the monomers in the presence of dyes in a dye-monomer matrix resulting in a polymer matrix, and wherein the dyes were subsequently removed from the polymer matrix yielding the molecularly imprinted polymers;
b.) one or more surfactants selected from the group consisting of anionic surfactants, nonionic surfactants, cationic surfactants, zwitterionic surfactants, and amphoteric surfactants;
c.) at least one water-soluble and/or water-insoluble builder.

2. A detergent according to claim 1 , wherein the ethylenically monomers comprise mono- or polyethylenically unsaturated mono-, di-, or tricarboxylic acids, and mixtures thereof.

3. A detergent according to claim 1 , characterized in that it contains the molecularly imprinted polymer in amounts from 0.01% by weight to 5% by weight.

4. The detergent according to claim 1 , characterized in that one or more additional monomers selected from the group consisting of acrylamide, methacrylamide, 2-vinylpyridine, 4-vinylpyridine, N,N,N-trimethyl-N-(4-vinylbenzyl)ammonium chloride, vinylpyrrolidone, vinylimidazole, N-benzene-N′-vinylimidazolinium bromide, divinylbenzene, methylenebisacrylamide, styrene, cyanostyrene, and acrylonitrile are used for preparing the polymers.

5. The detergent according to claim 1 , wherein the dyes are selected from the group consisting of: azo dyes, reactive dyes, direct dyes, pigment dyes, and mixtures thereof.

6. A method for washing textiles in surfactant-containing aqueous solutions, wherein textiles are contacted with the detergent according to claim 1 in an aqueous solution.
