Abstract
Abstract Oxidizable developer-coupler combinations wherein the coupler is a water-soluble polyhalogen 3-aminophenol are stable in the absence of free oxygen and chemical oxidizing agents. They provide hair dyeings of specially desirable shades. The dyeings are color fast, wash-fast, thermostable, and non-toxic. The combinations can be applied in customary vehicles. Their dyeing properties are developed by air oxidation, by peroxides, or by both at an acid, neutral or alkaline pH.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
44 words
An oxidizable developer-coupler combination for use in the dyeing of hair, comprising a water-soluble polyhalogen 3-aminophenol of the formula: ##STR3## wherein two or three of the R's are halogen and the other R or R's are hydrogen, as the coupler, and a developer therefor.
Claim 2
Dependent Claim
44 words
An oxidizable developer-coupler combination for use in the dyeing of hair, comprising a water-soluble polyhalogen 3-aminophenol of the formula: ##STR3## wherein two or three of the R's are halogen and the other R or R's are hydrogen, as the coupler, and a developer therefor.
Claim 3
Dependent Claim
26 words
