DERMAPOL-H are solubilised metal-complex dyes that can be thinned out either in water and in water miscible organic solvents. They represent a completely new spray dyeing system. DERMAPOL-H dyes are highly concentrated and have strong dyeing power. Being light fast, they allows to obtain uniform and very shiny dyeings. They can be used in spray dyeing, curtain dyeing, by rotary machine and in dip dyeing. They are particularly bright, so they can be used to correct nubuk leather and to dye seasons.
