Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
43 words
A process for coloring a thermoplastic resin which comprises incorporating into said resin while said resin is in a molten state a colorant in the form of a polyalkyleneoxy-substituted chromophore group in a minor amount sufficient to provide coloration to said thermoplastic resin.
Claim 2
Dependent Claim
43 words
A process for coloring a thermoplastic resin which comprises incorporating into said resin while said resin is in a molten state a colorant in the form of a polyalkyleneoxy-substituted chromophore group in a minor amount sufficient to provide coloration to said thermoplastic resin.
Claim 3
Dependent Claim
37 words
The process of claim 1 wherein said chromophore group is selected from nitroso, nitro, azo, diarylmethane, triarylmethane, xanthene, acridene, quinoline, methine, thiazole, indamine, indophenol, lactone aminoketone, hydroxyketone, stilbene, azine, oxazine, thiazine, anthraquinone, phthalocyanine or indigoid charomophore groups.
Claim 4
Dependent Claim
53 words
