A pigmented thermoplastic polymer masterbatch composition comprises a polyester of melting point above 200 DEG C. based on polyethylene terephthalate, a second polymer to plasticize the polyester, and pigment in an amount of at least 20 parts per 100 parts of composition. The second polymer can be also a toughening agent for the PET and can be a polycarprolactone, or a copolymer of ethylene with acrylic acid or vinyl acetate. |
