Abstract
A colored thermoplastic resin composition is provided which comprises a thermoplastic resin and a colorant in the form of an alkyleneoxy-substituted chromophore group provided in said thermoplastic resin in a minor amount sufficient to provide coloration to said thermoplastic resin. A process for preparing colored thermoplastic resins is also provided.
Claims10
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 in a molten phase so as to distribute said colorant throughout the mass of said thermoplastic resin whereby said colorant is essentially non-extractable from said resin.
A colored thermoplastic resin composition which comprises a thermoplastic resin selected from polyvinyl chloride and polyvinylidene chloride and a colorant in the form of a polyalkyleneoxy-substituted chromophore group provided in said thermoplastic resin in a minor amount sufficient to provide coloration to said thermoplastic resin.
