Abstract: 

In this work, the behavior of leuco solutions of vat dye was studied by using their spectrophotometeric data. Initially, the leuco solutions of C.I.Vat Green 1 were prepared with different concentration of sodium hydrosulfite and soda. Then, the absorbance spectral of leuco solutions were measured by spectrophotometer. The relationship between color and absorbance of leuco solution and concentration of soda and sodium hydrosulfite was studied. The obtained result shows, that the color and absorbance of leuco solution depend on the amount of soda and sodium hydrosulfite. Beside, the reduction properties of sodium hydrosulfite depend on the concentration of soda. Subsequently, the leuco solution was simulated by using subtractive color mixing low.
