Features:
(1) Light fastness
Differences in colors( Full shade and tint shade) between the exposed and the corresponding unexposed contols were assessed according to the blue scale.(Class8: Superior to Class1:Inferior)
(2) Resistance to acid (2% H2SO4), alkali (NaOH) aqueous solution
The pigment sample is suspended in each chemical solution.
After drying, the color change in evaluated in accordance with gray scale(*Remarks)
(3) Water resistance
The pigment sample is dispersed in water, heated and filtered. The resistance to water is evaluated based on the degree of coloration of the filtrate. The evaluation shall be carried out in accordance with gray scale(*Remarks).
(4) Resistance to solvent
Solvent is added directly to the pigment to be extracted, and the resistance to solvent is evaluated according to the dgree of coloration of the extract.
