Color concentrates for thermoplastic biofiber composites are disclosed. The concentrates employ three factors to achieve concentrated delivery of color to the processing machine and excellent and substantially uniform dispersion of color in the processing machine: melt flow of the concentrate exceeding at least 4 g/10 min. using ASTM D-1238; pellet size of the concentrate such that at least 50 pellets weigh less than one gram; and weight percent of the colorant ingredients in the concentrate exceeding at least 30 weight percent.

Colorant concentrates for thermoplastic biofiber composites

A liquid color concentrate is disclosed, having a liquid acrylic-based polymer carrier; colorant; and optionally other functional additives. The colorant can be one or more pigments, one or more dyes, or combinations thereof. The liquid polymer is compatible with a variety of plastic resins, especially optically clear plastic resins, such as polycarbonate, polymethyl methacrylate, and styrene-acrylonitrile.
