ABSTRACT:
A dispersible inorganic pigment composition in which the surface of a finely divided inorganic pigment is coated with a substance which renders the surface hydrophobic and then with a thermoplastic polymer and a process for the preparation of the composition. The composition is readily dispersible in thermoplastics and paints and it can be used to color thermoplastic materials directly, avoiding the preparation of a master batch.
