Prima Chemicals, located in Ahmedabad, Gujarat, India was founded in 1976 for manufacturing Pyrazolones, which are used as intermediates for Pigments, Acid dyes and Solvent Dyes. What began as a small unit is now the single largest manufacturer of Pyrazolones derivatives in the world.

Our strength is our knowledge, hard work and humble beginnings and hence, we always opt for niche segments where technical expertise and active management involvement is needed to carry out the production. Based on this trend, we have diversified into a wide range of products having equally diverse applications. Prima group now has 6 manufacturing units spread over three group companies.

This led us to start manufacturing of a very specialized segment of Solvent Soluble metal-complex Solvent Dyes – Primasol Dyes in the year 2002 having applications for Paints, Enamels, Wood Coatings, Printing Inks, Foil Printing and Leather Topcoats. We are also manufacturing Solvent Black 29 as part of our Primasol Range and are proud to admit that we are the only manufacturer of Solvent Black 29 in India.

In 2003, further development led us to start manufacturing Polymer-soluble Solvent Dyes – Primaplast Dyes having applications for Masterbatches, Engineering Plastics and Manmade Fibres.

To cater to the continuous and ever-growing demand for our solvent dyes, we have started a new manufacturing unit-Prima Chemicals Unit-II located in the industrial area of Vatva, Ahmedabad.
