Väriainepohjaiset

Väriainepohjaiset refers to a category of materials or products that primarily rely on dyes for their coloration. This contrasts with pigments, which are insoluble particles that scatter light to produce color. Dyes are typically soluble substances that impart color by being absorbed by the material they are applied to.

Common applications of väriainepohjaiset materials include textiles, inks, food coloring, and some cosmetic products. In textiles, dyes penetrate the fibers, providing vibrant and often deep colors. In printing inks, soluble dyes allow for transparent and bright hues, though they may be less lightfast than pigment-based inks. Food colorings often utilize dyes to enhance the visual appeal of processed foods.

The selection of a dye depends on factors such as the substrate to be colored, the desired color fastness (resistance to fading from light, washing, or chemicals), and safety regulations, especially for food and cosmetic applications. While dyes can offer brilliant colors and good transparency, they can sometimes be more prone to fading than pigments.
