pigmentteistä

Pigmentteistä is a Finnish term referring to pigments. Pigments are colored substances that are insoluble in the medium in which they are dispersed, typically a binder. Unlike dyes, which dissolve in their medium, pigments remain as solid particles. This insolubility is a key characteristic that allows them to impart color and opacity to various materials.

Pigments are broadly categorized into organic and inorganic types. Inorganic pigments are derived from mineral compounds and often exhibit excellent lightfastness and durability. Examples include titanium dioxide (white), iron oxides (reds, yellows, browns), and cadmium pigments (bright reds and yellows). Organic pigments, on the other hand, are carbon-based compounds and can offer a wider range of vibrant colors, though some may be less stable to light and weathering than their inorganic counterparts. Examples include phthalocyanine blues and greens, and azo yellows and reds.

The properties of a pigment, such as its hue, saturation, brightness, opacity, particle size, and chemical stability, are crucial for its application. These properties determine how the pigment will perform in paints, inks, plastics, cosmetics, and other products. The development of new pigments and improvements in pigment manufacturing continue to expand the possibilities for color in countless applications. The choice of pigment is often a balance between desired color characteristics, performance requirements, and cost.
