    摘要: Disclose are polyester color concentrates, especially amorphous and partially-crystalline, polyester color concentrates, comprising a polyester having copolymerized therein colored residues of at least one polyester-reactive, thermally-stable methine colorant compound. The color concentrates may be used to impart yellow shades and colors to various polymeric materials, shaped articles fabricated of and coatings formulated from such polymeric materials and, especially, personal, medical and home care products where non-extractability of the colorant material is essential. Also disclosed are colored semicrystalline powders derived from the color concentrates.
