چکیده
|
The water solubility kinetics of two synthesized mono azo naphthalimide based disperse dyestuffs in the presence of two different dispersing agents, namely irgasol dam and lyoprint ev were investigated at various temperatures. an exponential equation was found to describe the dissolution process. addition of irgasol dam and lyoprint ev dispersing agents increased the dissolution rate of both synthesized dyestuffs. the dissolution of the methyl naphthalimide derived dyestuff in water as expected was more than the propylnaphthalimide derivative. the dyeing depth and the leveling properties were also higher for the methyl derivative than the propyl derivative.prog. color colorants coat. 4(2011), 107-112. institute for color science and technology
