Claims
- 1. A composition of matter comprising:
- (A) from about 0.2% to about 15% of a dye selected from the group consisting of water-soluble, ortho-substituted triarylmethane dyes which have in their structure the moiety. ##STR4## wherein X is selected from the group consisting of substituent groups other than hydrogen or methyl and Y is selected from the group consisting of X, hydrogen and methyl,
- (B) an amount of a water-soluble bromide salt which provides from about 0.5% to about 18% by weight of bromide ion to said composition, and

- 2. The composition of claim 1 wherein the water-soluble bromide salt is present in an amount sufficient to provide from about 2% to about 8% by weight bromide ion to said composition and the water-soluble ammonium ion is present in an amount sufficient to provide from about 0.5% to about 1.5% ammonium ion to said composition.
- 3. The composition of claim 2 wherein the bromide salt is selected from the group consisting of alkali metal and ammonium bromides.
- 4. The composition of claim 3 wherein the ammonium bromide is the salt which provides both ammonium ions and bromide ions.
- 5. The composition of any one of claims 2, 3 and 4 wherein the X substituent on the dye is selected from the group consisting of halogen, sulfonate, carboxylate, phosphate, and hydroxyl, and the Y substituent is hydrogen.
- 6. The composition of claim 5 wherein the dye is selected from those having the Color Index designation 42053, 42090, 42045 and 42100.
- 7. The composition of claim 6 which additionally contains from about 5% to about 95% of a surfactant.
