Abstract:
1. A liquid color concentrate for plastic articles, comprising: (a) colorant; (b) a carrier for the colorant consisting essentially of a liquid polymer of an acrylic monomer; and optionally (c) surfactant, and optionally (d) functional additives, wherein the liquid polymer is the carrier for letdown of the colorant with consistent and precise metering of the colorant into a compound at a rate from about 0.01 weight percent to about 2.0 weight percent of colorant to the compound, wherein the liquid polymer is a homopolymer or a copolymer having a weight average molecular weight ranging from about 500 to about 200,000, wherein the liquid polymer has a glass transition temperature ranging from about −20° C. to about −100° C., and wherein the liquid polymer comprises from about 60 to about 95 weight percent of the liquid color concentrate.
