Abstract

A polyolefin composition having enhanced dyeing capabilities containing: (a) a polyolefin; (b) from 0.01 to 10% by weight, based on the weight of the polyolefin in, of a migratable amphiphile, excluding phenolic and sulfur-containing stabilizers and n-octyl phenyl salicylate; and (c) from 0.01 to 1000 ppm of a transition metal, based on the weight of the polyolefin.
