Colour Correction of Plastics |  |
Colour correction is a term used to describe the effect observed when low concentrations of ultramarine blue or violet pigments are added to media, such as plastics, which possess an inherent yellowish tint. Even the most effective whiteners for plastics, such as titanium dioxide, show faint degrees of yellowness. Ultramarines and manganese violet pigments, when added in trace quantities, counteract yellowness to produce a neutral, or ‘whiter than white’ shade.
Benefits of ultramarine pigments in colour correction:-
· Enhanced whites
· Excellent natural and artificial light performance
· Range of subtle tints
· Precise shade control
 Excellent Day and Artificial Light Performance
Ultramarines and manganese violet do not exhibit fluorescence. Unlike optical brightening agents, they give improved performance both in daylight and under artificial illumination. Excellent lightfastness can also be achieved, even at extremely low concentrations.
