Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
72 words
A colored thermoplastic resin composition which comprises a thermoplastic resin and a colorant in the form of a polyalkyleneoxy-substituted chromophore group incorporated into said thermoplastic resin in a minor amount sufficient to provide coloration, while said thermoplastic resin is dissolved in a solvent so as to distribute said colorant throughout the mass of said thermoplastic resin and thereafter said solvent is evaporated so that said colorant is essentially non-extractable from said resin.
Claim 2
Dependent Claim
72 words
A colored thermoplastic resin composition which comprises a thermoplastic resin and a colorant in the form of a polyalkyleneoxy-substituted chromophore group incorporated into said thermoplastic resin in a minor amount sufficient to provide coloration, while said thermoplastic resin is dissolved in a solvent so as to distribute said colorant throughout the mass of said thermoplastic resin and thereafter said solvent is evaporated so that said colorant is essentially non-extractable from said resin.
Claim 3
Dependent Claim
39 words
The colored resin composition of claim 1, wherein the 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 chromophore groups.
Claim 4
Dependent Claim
55 words
The colored resin composition of claim 2, wherein the alkyleneoxy substituent of said colorant is selected from polyalkylene oxides and copolymers of polyalkylene oxides in which the alkylene moiety of the polymeric substituent contains 2 to about 4 carbon atoms and such polymeric substituent has a molecular weight of from about 132 to about 10,000.
Claim 5
Dependent Claim
31 words
The colored resin composition of claim 1 wherein said resin is selected from polyolefin polymers and copolymers, polystyrenes, polycarbonates, ABS, polyvinyl chloride, polyvinylidene choloride, cellulosic resins, acrylic resins, polyamides and polyesters.
Claim 6
Dependent Claim
13 words
The colored resin composition of claim 4 wherein said resin is a polyolefin.
Claim 7
Dependent Claim
26 words
The resin of claim 5 wherein said polyolefin is selected from polyethylene, linear low density polyethylene, polypropylene, polybutylene and copolymers made from ethylene, propylene and/or butylene.
Claim 8
Dependent Claim
78 words
A colored thermoplastic resin composition which comprises a thermoplastic resin selected from polyvinyl chloride and polyvinylidene chloride and a colorant in the form of polyalkyleneoxy-substituted chromophore group incorporated in said thermoplastic resin in a minor amount sufficient to provide coloration, while said thermoplastic resin is dissolved in a solvent so as to distribute said colorant throughout the mass of said thermoplastic resin and thereafter said solvent is evaporated so that said colorant is essentially non-extractable from said resin.
Claim 9
Dependent Claim
78 words
A colored thermoplastic resin composition which comprises a thermoplastic resin selected from polyvinyl chloride and polyvinylidene chloride and a colorant in the form of polyalkyleneoxy-substituted chromophore group incorporated in said thermoplastic resin in a minor amount sufficient to provide coloration, while said thermoplastic resin is dissolved in a solvent so as to distribute said colorant throughout the mass of said thermoplastic resin and thereafter said solvent is evaporated so that said colorant is essentially non-extractable from said resin.
Claim 10
Dependent Claim
22 words
The colored resin composition of claim 1 wherein said chromophore group is selected from azo, anthraquinone, triaryl methane and methine chromophore groups.
Claim 11
Dependent Claim
34 words

Claim 12
Dependent Claim
55 words
A process for coloring a thermoplastic resin which comprises incorporating into said resin while said resin is dissolved in a solvent, a colorant in the form of a polyalkyleneoxy-substituted chromophore group in a minor amount sufficient to provide coloration to said thermoplastic resin and thereafter evaporating said solvent to provide a colored thermoplastic resin product.
Claim 13
Dependent Claim
55 words
A process for coloring a thermoplastic resin which comprises incorporating into said resin while said resin is dissolved in a solvent, a colorant in the form of a polyalkyleneoxy-substituted chromophore group in a minor amount sufficient to provide coloration to said thermoplastic resin and thereafter evaporating said solvent to provide a colored thermoplastic resin product.
Claim 14
Dependent Claim
37 words
