ABSTRACT:
Provided are novel polyester compositions containing copper phthalocyanine sulfonamide colorants copolymerized therein. Also provided are amorphous color concentrates, partially-crystalline color concentrates and semi-crystalline color concentrates. These polyester compositions are particularly useful for use as colored packaging materials and for colorants for personal, medical, and home care products where non-extractability of the colorant residue is important.
