Abstract
Poly(arylene sulfide) compositions are pigmented with black carbonaceous pigments selected from at least one of finely divided bituminious coal, carbonized rice hulls, bone blacks, and micropulverized petroleum coke in an amount sufficient to provide the black pigmentation desired with little or no deleterious effect on the mechanical properties such as flexural and tensile strengths of the resin.
