Because they are made from organic bases, basic dyes get their name. Because they ionize in water and produce colorful cations, they are also known as cationic dyes According to definitions, a basic dye is a cationic dye that exhibits substantivity for acidic forms of acrylic fiber and for cotton that has been tanned. This refers to the former significance of this class of dye in the dyeing of cotton. Basic dyes are referred to as cationic dyes because, when dissolved in water, they produce colorful cations with distinctively high tinctorial strength and brilliance.
Salts of colored bases with cationic properties make up basic dyes. On anionic substrates, where electrostatic attractions develop, basic dyes are applied. Cotton cannot be dyed with basic colors because the structures are neither planar nor sufficiently big for adequate substantivity or affinity. Because the chromophore in basic dye molecules has a positive charge, these dyes are known as cationic dyes. On the basic side of the isoelectric points, the fundamental dyes react. Salts, typically chlorides, that contain the dyestuff as the basic or positive radical are known as basic dyes. Powerful coloring chemicals, and basic dyes. Wool, silk, cotton, and modified acrylic fibers are all subject to it. Paper coloring also involves the use of basic pigments.
1. Cationic nature: These colors have cationic ionic nature.
2. Shade range: These dyes have an infinitely wide variety of shades, are highly tinctorial, bright, and many of their hues have fluorescent qualities.
3. Solubility: In the presence of glacial acetic acid, these dyes have excellent solubility in water.
4. These colors have poor leveling properties because of their high strike rate.
5. Affinity: These dyes have no affinity for cellulose materials but have a strong affinity for wool, silk, and cationic dye-able acrylic. Cellulosic material needs to be properly mordanted in order to be dyed with basic colors.
6. Fastness characteristics: The wet fastness is good, while the light fastness is poor to moderate.
