Differences between Dyes and Pigments in Flooring
Both pigments and dyes are used to color different materials, but the way in which they do it is very, very different. Think for a moment of two glasses of water standing side by side — the one is mixed with salt, the other with mud. Solubility The muddy water is brown, with all sorts of dirt and mud particles suspended in the water. Give it enough time and the particles will settle on the bottom of the glass. This mixture is called a suspension.
The major difference between dyes and pigments is the particle size. Dyes are much finer than pigments. Therefore dyes are not UV stable whereas pigments are usually UV stable. Dyes, also known as colorants in which the coloring matter is dissolved in liquid, are absorbed into the material to which they are applied.
The Differences Between Pigments and Dyes
There are fundamental differences between dyes and pigments which are best explained by the definitions below. Dyes are intensely colored or fluorescent organic substances only, which impart color to a substrate by selective absorption of light. ETAD seeks to base its positions on sound science and to coordinate the efforts of its members to minimize any possible adverse impact of organic colorants on health and environment. Member companies are obliged to adhere to the ETAD Code of Ethics, which is based on the principles of responsible care. Pigments are colored, black, white or fluorescent particulate organic or inorganic solids which usually are insoluble in, and essentially physically and chemically unaffected by, the vehicle or substrate in which they are incorporated.

It seems that you're in Germany. We have a dedicated site for Germany. In this book the authors go back to basics to describe the structural differences between dyes and pigments, their mechanisms of action, properties and applications. They set the scene by explaining the reasons behind these differences and show how dyes are predominately organic compounds that dissolve or react with substrates, whereas pigments are predominantly finely ground inorganic substances that are insoluble and therefore have a different mode of coloring.
