Pigment Geen 7 Usage And Synthesis

Description

Pigment Green-7 is a water-dispersed pigment, exceptionally lightfast, yields an intense phthalo green, and is formulated specifically for the coloring of paper pulp. It is easy to use and requires no rinsing; directions included. It has high tintorial strength and excellent fastness to solvents, heat, light, & weathering^1,2. To ensure maximum color intensity and proper adhesion to the pulp, a retention agent must be added to the pulp before the pigment is applied1. It belongs to the Phthalocyanine Green Pigment2. It is widely used in paint industry, plastic industry, textile industry, ink industries, leather industries, coating industry, paper industries, and rubber industry^2,3.
