Basic Dyes are also known by name of cationic dyes and comprise class of synthetic dyes that works as base. Upon mixing in water, they assist in formation of colored cationic salt that react with anionic sites on surface of substrates. These basic dyes provide assistance in producing bright shades featuring superior tinctorial values on textile materials.
It is known as CORANTES BASICOS in Brazil. It is known as COLORANTES BASICOS in Mexico, Colombia, Peru, Argentina, Paraguay, Uruguay, Chile, Guatemala, Honduras, Costa Rica, Nicaragua.
