Tio2 pigments resistant to discoloration in the presence of polymer additives

Inorganic pigments coated with an organic acid in the amount of about 0.01-6 percent, based on the weight of the inorganic pigment, have excellent resistance to polymer yellowing or discoloration and do not appear to degrade important polymer properties or cause problems in the processing of the pol...
