Solvent Dyes

Our dyes are solvent soluble dyes of high quality for wide use in inks and coating industries. Ensuring superior solubility in organic solvent systems, these solvent dyes are applied as dispersion in a water bath. The dye is commonly known as disperse dye have wide application for coloration of polyester fibers. In contrast to ordinary dyes, our solvent dyes are pure in nature and contain low amount of impurities. Catering to the special needs of plastics coloration, these dyes can withstand over 350°C of temperature during extrusion and injection moulding process. The dyes are best for coloring a variety of solid materials, such as nylon, polyester, acetates, PVC, acrylics, PMMA, polystyrene, PETP and styrene monomers.

Solvent Dyes


What are Solvent Dyes?

A solvent dye is a dye soluble in organic solvents. It is usually used as a solution in an organic solvent. Solvent dyes are used to color organic solvents, hydrocarbon fuels, waxes, lubricants, plastics, & 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. Names of solvent dyes are often generic, of the scheme "solvent", e.g. Solvent Red 23, Solvent Red 24, Solvent Yellow 2, Solvent Yellow 14, Solvent Blue 35, etc.

Oil Soluble Dyes

Red and yellow solvent dyes are often azo dyes, green and blue ones tend to be anthraquinone dyes. is also called oil dye, oil-based dye or solvent based dyes. One type of non-polar organic solvents that is commonly used with oil dyes is petrol. Accordingly, oil solvent dyes are often used in the automotive industry to color petrol fuel and other hydrocarbon-based fuel oils. Oil can be colored by oil soluble dyes. In addition, many solvent dyes are used as components by the biological stain manufacturing community to produce stains that will identify various cell structure components in medical diagnostics and scientific research.

Oil soluble solvent dyes have better temperature stability in engineering plastics, very high brightness and do result in completely transparent plastics without any haze and light scattering. Processing is easy and process parameters like viscosity remain unaffected. Process conditions for engineering plastics like polystyrene, ABS, PC, PMMA, PA and others are quite severe. During extrusion and injection moulding of PC the dyes have to withstand temperatures up to over 350°C for some minutes. Only selected oil solvent dyes do show the needed chemical resistance. Chemical stability also leads to long lasting final products which have to withstand sunlight and weather. As an example, red car taillights will last as long as the car itself without losing the bright red colour. To achieve this, the right transparent polymers and right dyes have to be taken.

Commodity polymers like Polyethylene, polypropylene, plasticized PVC or rubber are soft at low temperatures. we do not recommend any solvent dyes for coloration of these polymers but pigments have to be used.

Besides plastics industry, a major application for solvent dyes is printing or solvent based writing ink. Furthermore, oil soluble dyes are widely used in rubbers, oil inks, spinning, waxes, smoke, paints, color paste, transfer printing, marking pens, ball point pens, candles, oil, fats, solvents, bitumen, lubricants, marking inks, inkjet printing inks, dye sublimation printing, glass coloration, signalling smoke, firework and in the pyrotechnics industries, gold imitation, other transparent metallic effects of metallized polyester films, other hydrocarbon-based nonpolar materials.

Nigrosine Blacks include oil soluble nigrosine (C. I. solvent black 7), spirit soluble nigrosine or alcohol soluble nigrosine (C. I. solvent black 5), MS conc nigrosine (C. I. acid black 2) and aniline black (C.I. pigment black 1). All Nigrosine do show absorption in the infrared light making them suitable for optical character recognition. They are suitable for inkjet inks, ball point pen inks, solvent marker pen inks, water sign pen inks, industrial inks, ribbon inks, carbon paper, shoe polish, plastics, phenolic resin, polyamide resin, urea resin, lacquers, varnishes, wood stains, leather, cotton, flax, metallic products, coatings, alcohol based oil soluble self-drying alkyd coatings, nitryl paints, water based coatings, thermosetting coatings, stationery commodities, alcohol based printing ink, plastics application such as acrylic resin, unsaturated polyester resin, fibrin resin, Bakelite, polyester alkyd, polyvinyl chloride, polycarbonate, polystyrene, polypropylene, non-water soluble coloring of leather and fur, coatings, printing ink, positive charge control agent in electrostatic printing powder, coloring for stationery.

Metal-complex Solvent Dyes

Metal-complex solvent dye is shorted as metal-complex dyes, these are mainly anionic chromium and cobalt complexes of azo dyes. The cation is either a sodium ion or a substituted ammonium ion. These dyes are normally soluble in alcohols, glycol ethers, ketones and esters. Solvent dyes of metal complex have a higher colour strength and a higher light stability, because metal particles go into the dyes' molecule.

Wood stain or wood coating is designed for decorative and protective purposes, it is usually composed of a transparent or semi-transparent colorant solution. The solution penetrates the wood without hiding the grain, and indeed often enhancing it. The main requirements of wood colorants are transparency, high saturation, high brilliance, good bleed and chemical resistance, good solvent compatibility and high light fastness.

Metal-complex solvent dye is mainly used in wood stains, printing inks, aluminium foil coloring, hot stamping foil coloring, paints, coatings, leather finishes, baking finishes, stationery ink and plastic coatings. Furthermore, metal- complex solvent dyes own following advantages: 1. excellent solubility; 2. good compatibility with most resins; 3. bright colors; 4. excellent chemical resistance; 5. free of heavy metals; 6. liquid form is available.

Uses For Solvent Dyes

Their very nature - soluble in non-polar mediums - allows their versatility and many uses. Oil or solvent dye is used in applications such as foil printing, printing inks, marking pens, ball point pens, candles and other waxes, polishes, leathers, wood stains, acrylic resins, varnishes & shellacs. They are used in signaling smoke and in the pyrotechnics industry. These dyes are also used to color lubricants in the automotive and industrial cutting industries. However, the most frequent application of solvent dyes is in the plastics industry. Within the indus-trial plastics community, solvent-based dyes are used to color a variety of solid materials, such as acetates, nylon, polyester, acrylics, PVC, PMMA, PETP, polystyrene and styrene monomers. In addition, many solvent dyes are used as components by the biological stain manufacturing community to produce stains that will identify various cell structure components in medical diagnostics and scientific research.
