<；p>；A firm known as M/s. I.M. DYE CHEM, based at AHMEDABAD (Gujarat) has first time invented Reactive Powder Blue P3R indigenously through its constant Research & Development for many years The promoter of this firm is engaged in family business of dyes and chemicals since last few decades. Reactive Powder Blue P3R is manufactured from different types of chemicals in reaction vessel by applying steam at specific temperature and pressure and filtration method. Reactive Powder Blue P3R is used for printing of cotton cloth by screen printing machine by hot process. These dyes are applied under strong alkaline condition at high temperature of application compared to cold dyes. These dyes contain very good fastness property to wash； light etc. and also more self life compared to other dyes. The most important characteristic of Reactive Powder Blue P3R is the formation of covalent bonds with the substrate to be colored i.e. the dyes forms a chemical bond with cellulose which is the main component of cotton fiber. The market demand of Reactive Powder Blue P3R is very high in under developed countries like Pakistan, Bangladesh and Middle East. Thus there remains a considerable need for Reactive Powder Blue P3R in the market for dyeing industry.<；/p>；
