Solvent Dyes are used to color organic solvents, hydrocarbon fuels, waxes, lubricants, Plastics , and other hydrocarbon-based nonpolar materials. Fuel Dyes are one use of solvent dyes. Their molecules are typically nonpolar or little polar, and they do not undergo ionization. They are insoluble in water. They form a colloidal solution in solvents.They have poor (Basic Dyes) to good (metal complex based) light fastness.
Solvent dyes are used for gold imitation (and other transparent metallic effects) of metallized polyester films. Also used in marking inks, inkjet inks, glass coloration, and so on.
Names of solvent dyes are often generic, of the scheme "solvent
Red and yellow solvent dyes are often azo dyes, green and blue ones tend to be anthraquinone dyes.
Cationic Dyes are a class of basic dyes. Dyeing speed, poor levelness, high color yield, with the retarding agent can be dyed dark.
Cationic dye affinity for acrylic big, due to the adsorption of fast and slow diffusion staining, easy to produce uneven dyeing phenomenon, and once produced uneven dyeing, dyeing difficult by extending the method to correct time. Cationic dyes, in order to obtain uniform staining, dyeing rate should be appropriately reduced. Factors affecting the rate of cationic dyes in addition to the type of acrylic, there are temperature, pH value of the dye bath, electrolytes, retarding agent.
