Description
A bright orange azo colorant. Pyrazolone is extensively used in rubbers, but has had limited use in polyolefins and is not used in plasticized plastics because of its tendency to migrate and bleed. It is colorfast to water and detergents. Pyrazolone has been used in some air-drying paints and printing inks.
