| Industrial dyes are quite often used in multiple industries | | | | about industrial pigments and their types. Pigments are |
| these days; so is the case with pigments. If we talk | | | | basically the materials that make a modification in the |
| about industrial dyes, they are basically coloring, ionizing, | | | | color of the transmitted light owing to their attribute of |
| and aromatic compounds that are used in numerous | | | | selective absorption of the wavelength. The change in |
| applications across various industries. Dyes have the | | | | the transmission of light varies with fluorescence, |
| property to show an affinity towards the substrate. | | | | phosphorescence, as well as with other forms of |

| industrial dyes are toxic and carcinogenic in nature. | | | | are generally used in inks, coloring paints, cosmetics, |
| Anyway, at present, dyes found their application in | | | | eatables, etc. Nowadays there are various types of |
| industries like plastic, cement, cosmetics, rubber, paper, | | | | pigments available in the market, out of which some |
| textiles, medicine, to name a few. Some primary | | | | primary types of pigments are given under: |
| varieties of industrial dyes are mentioned under: | | | | 1) CLC Pigments: Cholesteric Liquid Crystal (CLC) |
| 1) Digital Textile Printing Dyes: In digital printing, computer | | | | pigments are made from CLC films. These pigments |
| controlled ink-jet nozzles or charged drums are used. | | | | are nowadays increasingly used in security machines |
| The physical surfaces over which the digital prints are | | | | and also as an impediment to the counterfeit of |
| reproduced include common paper, photographic | | | | currency notes, legal documents, etc. |
| paper, plastic, cloth, etc. The popular varieties of dyes | | | | 2) Fluorescent Pigments: These pigments have the |
| used for this purpose are acid inks, disperse inks, | | | | quality of changing the ultraviolet light into the desired |
| reactive inks, and dye based inks. | | | | color. They form the vital element of any kind of |
| 2) Leather Dyes: Tanneries usually make use of | | | | fluorescent material. The fluorescent pigments are |
| around 50-100 different varieties of leather dyes. Each | | | | mostly used in textile field, solvent based paper coating, |

| leather. The dyes used in this industry include direct, | | | | 3) Organic Pigments: Organic pigments consist of solid |
| acid, mordant, reactive, and basic dyes, among others. | | | | particles and they are insoluble in the application |
| 3) Optical Brighteners: Also known as optical agents, | | | | medium. There are two basic varieties of these |
| optical brighteners are the dyes that possess the | | | | pigments, namely natural and synthetic. Organic |
| attribute of absorbing the violet and ultraviolet region of | | | | pigments are generally used for coloring or coating |
| the electromagnetic spectrum, which results in the | | | | purposes (both decorative and protective) on plastics, |
| prominent re-emission of light in the blue region. This | | | | candles, paper, rubber materials, pharmaceuticals, etc. |
| dye is not suitable to be used in water (like in aquarium, | | | | 4) Ultramarine Pigments: They are a kind of inorganic |
| etc.), due to its toxic nature. | | | | pigments, which are non-poisonous and non-irritating in |
| 4) Sublimation Dyes: These dyes primarily found their | | | | nature. They are also one of the oldest varieties of |
| application in various types of printing. They can be | | | | pigments. They have two basic types, viz., ultramarine |
| found in several forms like inkjet inks, ribbons for | | | | blue and ultramarine violet. Ultramarine pigments found |
