Abstract
A system providing desirable properties for introducing a pigment to a polar polymer such as polyvinylchloride resin is disclosed. The system also is valuable in that pigments are conveniently dissolved or dispersed and blended in an a polyester component which is otherwise useful for polar polymer processing. Also disclosed is the mixing of the polyester component, phthalocyanine compounds, and the polyvinylchloride resins. Stronger color development is obtained by using the system of the present invention.
