Talk about fluorescent pigments!

Fluorescent pigment is a kind of pigment that reflects the hue of the pigment itself, but also reflects a part of the fluorescent pigment, which has a high brightness, and has a higher reflected light intensity than ordinary pigments and dyes, which makes people feel gorgeous and dazzling. Fluorescent pigments are mainly divided into inorganic fluorescent pigments and organic fluorescent pigments. Some metals, such as zinc, calcium, and strontium, can absorb the energy of gaze or artificial light after special treatment, store the light energy, and release the stored energy from the head in the dark to emit light, which is called luminous pigments, also known as inorganic fluorescent pigments. In addition to absorbing a part of visible light, organic fluorescent pigments can also absorb a part of ultraviolet light and convert it into visible light for release. As a result, the amount of reflected light is increased, and the brilliance of the pigment is increased. It is characterized by fluorescence effect in sunlight and bright color, but its light fastness is not good. There is also a fluorescent pigment that is synthesized, and its essence is a pigment-type fluorescent dye. Commonly used fluorescent pigments are fluorescent pink, fluorescent red, fluorescent rose, fluorescent orange red, fluorescent orange, fluorescent orange yellow, fluorescent yellow, fluorescent lemon yellow, fluorescent green, fluorescent blue, fluorescent violet, fluorescent purple peach, etc. Fluorescent pigments can be divided into thermoplastic, thermoset, and soluble water emulsion according to the carrier resin; According to the application to plastics, it can be divided into low temperature type, medium temperature type and high temperature type; According to the application to the coating category, it can be divided into water-based coatings, oil-based coatings and powder coatings; According to the environmental protection indicators, it can be divided into formaldehyde-containing and formaldehyde-free.

Fluorescent pigments have excellent performance in the coloring of plastics, sols, paper products, color pastes, inks, paints, coatings, masterbatches, chemical fibers, textiles, etc. In natural conditions, as well as in dim, light-starved conditions, fluorescent gloss has far superior visibility to traditional gloss, attracting attention earlier, faster, and for longer periods of time, and greatly increasing the chances of people looking back for a second or even a third look. The earliest and most widespread commercial applications of fluorescent pigments are in a wide variety of advertising. From the advertising signs in the shops to the huge advertisements on the highways; From all kinds of product packaging, to all kinds of magazine cover pages and advertising inserts, and so on. With the development of commodity economy and science and technology, fluorescent pigments and their properties have been widely used in more fields. For example, in terms of safety markings: fire fighting and rescue vehicles, rescue facilities and equipment, construction sites, hazardous equipment, other industrial equipment and places, traffic signs, clothing for traffic workers, clothing for forestry workers and hunters, etc.
