Abstract
Official abstract text for this publication.
A liquid colorant for use in molding or extruding plastic products comprises pigment dispersed in cottonseed oil.
First claim
Opening claim text (preview).
I claim the following: 1. A method of molding or extruding plastic parts comprising the steps of: a) providing a collection of pigments in powder form; b) providing a quantity of cottonseed oil in non-amidized and non-partially-amidized form for use as a cottonseed oil carrier; c) creating a plurality of single pigment dispersions each in the cottonseed oil carrier, each of the plurality of single pigment dispersions consisting of the single pigment and the cottonseed oil carrier; d) blending selected ones of the plurality of single pigment dispersions to create a blend of a desired color shade; e) milling the blend; and f) adding the blend to form thermoplastic resin in the course of molding or extrusion. 2. The method of claim 1 wherein the pigment in each of the plurality of single pigment dispersions comprises from about 50% to about 70% by weight of the dispersion. 3. The method of claim 1 wherein the pigment in each of the plurality of single pigment dispersions comprises from about 25% to about 80% by weight of the dispersion. 4. The method of claim 1 wherein the pigment in the blend of the plurality of single pigment dispersions comprises from about 25% to about 80% by weight of the blend. 5. A method of making liquid color for use in molding or extruding plastic parts comprising the steps of: a) providing a collection of pigments in powder form; b) providing a quantity of cottonseed oil in non-amidized and non-partially-amidized form for use as a cottonseed oil carrier; c) creating a plurality of single pigment dispersions each in the cottonseed oil carrier, each of the plurality of single pigment dispersions consisting of a single one of the pigments and the cottonseed oil carrier; d) blending selected ones of the plurality of single pigment dispersions to create a blend of a desired color shade; and e) milling the blend. 6. The method of claim 1 wherein the pigment in the blend of the plurality of single pigment dispersions comprises from about 25% to about 80% by weight of the blend. 7. The method of claim 5 further comprising adding at least one additive selected from the group comprising lubricants, blowing agents, light stabilizers, nucleating agents, antistatic agents and antioxidants, to the blend.
