DYECOM PIGMENTS

Pigments made by complexing soluble dyes with complexing agents, Dyecoms, are unique class of pigments used widely in printing inks, paper colorants, and other miscellaneous applications.  Unlike the manufacture of most other pigments, these pigments are manufactured by a 2-step process. The first step is to make the chromophore, a soluble dye, which is isolated and dried.  The second step is to solubilize the dye again and then render the dye insoluble by reacting it with the complexing agent.  Complexing agents are most often phosphomolybdic acid or copperferocyanine.  Other complexing agents can be used for special applications such as for coloration of food items.

Most Dyecom manufacturers will buy the finished dye from one manufacturer and then make the finished pigment by complexing this dye.  First Source Worldwide, LLC has a Dyecom source that in vertically integrated and makes both the soluble dye and then complexes it to make the finished pigment. This allows for more quality control of the final product, allowing for shade adjustments to match specific applications.

It should also be mentioned that these pigments are manufactured in India, thus avoiding the high tariffs currently in place for Chinese products.

Current products include Red 169, Red 81:3, Violet 27 and Violet 3.  If customers require other Dyecom pigments, they might already be in the development stage.
