Hostaperm Violet P-RL
Pigment Violet 23
Hostaperm Violet P-RL is a blue shade dioxazine pigment. It is a special pigment belonging to the P-grade range, being especially recommended for solvent based packaging printing inks. Due to the extremely low specific conductivity (< 0,2 mS/cm) it shows good water resistance when printing on plastic films. It exhibits high color strength, high gloss, high transparency and flocculation stability with very good rheological and excellent fastness properties.
