Imaging Materials: Diazo Compounds

For much of the 20th Century, Diazo chemistry was the primary route for Engineering Graphics, Printed Circuit Masters and Diazo Film Reproduction including duplicate microfilm.

Most, if not all, these technologies have been replaced with newer, digital technologies that offer better resolution, greater convenience, and at lower costs. This is a primary reason why Esprix began migrating to both Inkjet and electrostatic toner technologies by the late 1980s. Today, most of the European and all of the U.S. Diazo producers are extinct.

If you have a demand for Diazo, we can have it produced on a custom confidential basis. We have the resources to do this quickly. Neither Esprix, nor anyone else for that matter, carries significant inventories of these products as their commercial application is no longer relevant.
