Abstract
A masterbatch comprising pigment and demolding agent is provided. The demolding agent is selected from the group comprising low molecular weight polyolefin oils, low molecular weight polyolefin waxes, montan waxes and aliphatic or aromatic carboxylic acid esters of fatty acids and/or fatty alcohols, wherein the pigment content of the masterbatch is from 3 to 70 wt. %, based on the total weight of the masterbatch. The masterbatch is suitable for preparation of a polymer composition having improved pigment dispersion.
