Abstract
Described is particulate halogen-containing material, e.g., calcium hypochlorite, containing from about 0.1 to about 10 weight percent of colorant-treated particulate inorganic water soluble salt, e.g., sodium chloride. The colorant used with the sodium chloride salt is resistant to oxidation by the halogen specie in the material and is water dispersible. The amount of colorant used is from about 0.01 to about 5 weight percent, based on the inorganic salt. Preferred are the water dispersible phthalocyanine colorants.
