Abstract

A liquid colorant for use in molding or extruding plastic products comprises pigment dispersed in cottonseed oil.

Claims

1. A method of fabricating a plastic article of preselected color, comprising:

a. preparing a blend comprising solid plastic resin pellets and liquid color of a hue and in an amount to impart the preselected color to the article to be fabricated;

b. the liquid color comprising cottonseed oil;

c. forming the blend under pressure and heat into the plastic article;

wherein the liquid color comprises at least one additive to facilitate fabrication of the plastic article and the additive is selected from the group comprising lubricants, blowing agents, light stabilizers, nucleating agents, antistatic agents, and antioxidants.
