THE INVENTION
Appellants invention is drawn to a colored thermoplastic resin composition having an
anthraquinone dye incorporated therein while the resin is in a molten state. The dye has one or more
moieties containing repeating ethoxy, propoxy and butoxy groups attached through sulfonamide groups
to the anthraquinone ring.
THE CLAIMS
Claim 39 is illustrative of appellants invention and is reproduced below.
39. A colored thermoplastic resin composition which comprises a thermoplastic resin and a
colorant incorporated in and distributed throughout the mass of said thermoplastic resin while said resin
is in a molten state, whereby said colorant is essentially non-extractable from said resin, said colorant
has the formula:
A[SO N(R )-(Y)]
2 1 1-6
wherein A is an anthraquinone or condensed anthraquinone colored chromophoric radical;
Y is a polymeric substituent having from 4 to 200 residues selected from -CH CH O-, -
