Abstract

Water-soluble dyes have good solubility, brightness and long shelf life, but higher penetration, poor water and light fastness compare with pigment colorant on printing paper. How to increase light fastness of dyes is always an important issue on inkjet printing for photo. Dye containing carboxyl groups could improve water fastness had been studied but lacked off light fastness information [1,2,3].In this paper, a series of disazo dyes which diazonium group contained carboxyl groups and methoxyl groups included navy blue, red and yellow components were synthesized and evaluated showing good light fastness and high color strength.These diazo compositions form deep black shade and have been approved with high color strength and light fastness performance compared with commercial market product. This range of product is easy dissolved in aqueous and has good printing performance on inkjet application.
