Abstract:
An article provided by a plastics composition which comprises a transparent or translucent thermoplastics material having a colorant uniformly dispersed therein characterized in that the colorant comprises a blend of discrete particles at least 90% of which have a minimum dimension which is from 5 to 100 &mgr;m and a maximum dimension of no more than 0.5 mm, said particles being of a natural or synthetic crosslinked thermoplastic organic polymer which is compatible with the thermoplastics material such that the surface of the article is smooth and said particles being mechanically and thermally stable such that they did not degrade during processing that created the article, the blend comprising particles having at least two distinct colors, not black and not white, and the plastics composition containing 0.1 to 8 percent by weight of the blend of said polymer particles based on the weight of the plastics composition.
