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”) derived structure having improved stability to alkaline conditions. Thus, the colorant compositions resist decolorization, even at relatively high pH levels. The colorant compositions of the invention are useful as applied in polyolefins, such as polypropylene and polyethylene, as examples. These colorant compositions also may be employed in thermoplastics, such as PET, for example.
色料组合物可用于各种产品应用。例如,色料用于聚合物的着色,为水溶液提供颜色,并为固体或半固体产品(如洗涤剂)提供颜色。本文揭示了具有三苯甲烷(“TPM”)衍生结构的色料组合物,具有改善的稳定性以抵抗碱性条件。因此,即使在相对较高的pH值下,这些色料组合物也能抵抗褪色。本发明的色料组合物可应用于聚烯烃中,例如聚丙烯和聚乙烯。这些色料组合物也可用于热塑性塑料,例如PET。
