ABSTRACT:
Colorant compositions are useful for a wide variety of product applications. For example, colorants are used in tinting of polymers, providing colors to aqueous solution(s), and affording color to solid or semi-solid products such as detergents. Disclosed herein are colorant compositions having a triphenylmethane (“TPM”) structure having improved stability to alkaline conditions. Thus, the colorant compositions resist decolorization, even at relatively high pH levels.
