Salts are highly sensitive to heat and moisture and need to be always stored in cool dry place. Being freely soluble in water, it is used in dyeing process in two stages.

–  The first stage, involves material getting impregnated with naphthol solution.

–  In second stage, further development takes place with use of diazotized fast base.

Combining chemically with naphthol, it gets absorbed by fiber thus providing insoluble dye on fiber. These can be used in different dyeing methods including tub-dip, open beck, jigger, circulating liquor and padding methods where different material to liquor ratio is used in different dyestuff concentrations for achieving defined shades. These dyes are skin friendly and easy to apply.

Salts are widely used in the textile industry in processes involving wax prints and African prints. Finding wide usage in textile, plastic, chemical and pharmaceutical industry, these when dyeing with napthols offer economical usage. Furthermore, these are also used in achieving blue, maroon, yellow color shades that are not possible with other dyestuff. These dyes possess superior color fastness properties.


These color bases are widely used in:

– Textile

– Chemical

– Pharmaceutical
