Abstract: A pigment library and a method for preparing it are provided, which includes identifying a plurality of thermoplastic polymers and then selecting pigments useful in the plurality of thermoplastic polymers. The pigments are heat stable at the melt temperature of each of the plurality of thermoplastic polymers and are not chemically interactive or reactive with each of the polymers of the plurality of thermoplastic polymer. Further, each of the pigments in combination with each of the polymers of the plurality of thermoplastic polymers possesses the property of being lightfast, injection moldable, and fiber spinnable and also not crocking. A colorant database is then prepared using the pigment library. The colorant database is used with color matching software that predict formulations using the colorant database. The result is the development of formulations that minimize or eliminate metameric color effect under various lighting conditions across multiple polymers and end product types.
