Neutral Dyes

Neutral dyes are chromium metal dyes. They are mainly chelated at a ratio of 1:2 by coordination metal atoms (metal chromium, cobalt, etc.) and mother dye (acid azo dye) molecules, such as neutral orange RL, neutral gray 2BL. They are slightly less soluble in water than the metal complexes and can be dyed in a neutral or slightly acidic solution. Neutral dyes are suitable for the dyeing of vinylon, nylon, silk, wool and tussah. Neutral dyes have high fastness. Neutral Dyes
