RadionBase PBX Carbazole Violet is a radiation-curable dispersion of 31% Carbazole Violet (Pigment Violet 23) in a mixed oligomer system. Violet 23 is recognized as the "gold standard" for lighfastness and color retention among violet-shade pigments. This vehicle system has been optimized for use in paper and board, with possible applications in surface-treated or oxidized films as well. Recommended dosage of RadionBase PBX Carbazole Violet is 36%-50% by weight in a finished ink. RadionBase PBX series energy-curable bases feature soft easy-to-handle viscosity with excellent pigmentation levels.
