Abstract

The present invention relates to laundry care compositions comprising carboxylate dyes. The laundry care compositions can be laundry detergent compositions, laundry additive compositions such as fabric enhancer compositions or bleach additive compositions. Preferably, the laundry care composition is a laundry detergent composition. The composition can be a solid, such as a powder, tablet or bar, or a liquid. The composition can be in the form of a unit dose, such as pouch. Suitable unit dose pouches include single compartment and multi-compartment pouches.

First claim

What is claimed is:

1. A mono-azo carboxylate dye selected from

and mixtures thereof,
wherein R 1 is Independently selected from the group consisting of:
(a) unsubstituted or substituted C 1 to C 12 alkyl chains, optionally the alkyl chains comprising ether (C—O—C), ester and/or amide links, optionally, the alkyl chains are substituted with —Cl, —Br, —CN, —NO 2 , —SO 2 CH 3 , —OH and mixtures thereof; and
(b) (CH 2 CH 2 O) y ((CH 2 ) w NH) z Q;

wherein R 2 is (CH 2 CH 2 O) y ((CH 2 ) w NH) z Q′;
wherein y and y′ are independently selected integers from 0 to 39;
wherein the sum of y+y′ is in the range of from 3 to 30;
wherein w and w′ are independently selected from 2 and 3;
wherein z and z′ are independently selected from 0 and 1;
wherein z is 1 when y is 0; wherein z′ is 1 when y′ is 0;
wherein Q and Q′ are independently selected from the group consisting of H and Y;
wherein Y is an organic radical represented by Formula V

wherein independently for each Y group:
M is H or a charge balancing cation;
m is 0 to 5;
n is 0 to 5;
the sum of m+n is 1 to 10;
each R 12 is Independently selected from the group consisting of H, C 3-18 or C 4 -C 18 linear or branched alkyl, C 3-18 or C 4 -C 18 linear or branched alkenyl, and mixtures thereof;
at least one R 12 group is not H;
wherein at least one Q or Q′ group is Y;
wherein R 3 is selected from acid amide, C 1 -C 8 alkyl, heteroaromatic and aryl;
wherein R 4 is selected from CN, NO 2 , alkoxy, carboxylic acid ester, alkyl sulfonyl and arylsulfonyl;
wherein R 5 is selected from F, Cl, Br, CN, NO 2 , alkoxy, phenyl, benzyl, amine, alkyl, and carboxylic acid ester;
wherein R 6 is selected from H, CN, NO 2 , alkoxy, alkyl sulfonyl, arylsulfonyl and carboxylic acid ester;
wherein R 7 is selected from CN, SCN, F, Cl, and Br;
wherein R 8 is selected from C 1 -C 8 alkyl, heteroaromatic and aryl;
wherein R 9 is selected from CN, NH 2 C(O), NO 2 , and acetyl;
wherein R 10 is selected from C 3 -C 8 alkyl;
wherein R 11 is an acid amide.
