CHEMISTRY OF DYES


Classification of dyes

Classification of dyes

A dye is a colored substance that has an affinity to the substrate to which it is being applied. It is an ionizing and aromatic organic compound, with Chromophores as a major component. Their structures have Aryl rings that have delocalized electron systems. These structures are said to be responsible for the absorption of electromagnetic radiation that has varying wavelengths, based upon the energy of the electron clouds. Read More
