Permanent purple RL crude
?It has the same structure as and becomes the Permanent Violet RL after treating by pigment. At the same time, it also becomes the intermediate ofsun-resistant blue 108.

Pigment Violet RL is a purple powder used for coloring coatings, inks, rubber and plastics, and dope coloring of synthetic fibers.

The parent body of this class of pigments is triphenyldioxazine, which itself is orange and has no value as a pigment. Its 9,10-dichloro derivative can be used as a purple pigment after pigmentation.

There are fewer varieties of dioxazine pigments available, the most typical variety is permanent violet RL (C.I. pigment violet 23). The pigment is resistant to almost all organic solvents, so it can be used in many application media with good fastness.

The basic color of the pigment is red light violet, and a bluer variety can also be obtained through special pigmentation treatment. Its tinting strength is particularly high in almost all application media, and only a small amount can give a satisfact ory color depth.

?Product advantage
It has excellent heat resistance, light resistance and chemical stability, and has an overall good fastness to weather and solvent resistance.
