Abstract
The compositions comprise organic or inorganic pigments mixed with a combination of (a) waxy materials such as natural, synthetic, or petroleum waxes and (b) wax-like materials such as polyethylene glycols or hydrocarbon resins. These compositions are easily dispersible in thermoset and thermoplastic resins, require no special equipment, and can be let down directly.
