The process is generally limited to certain plastics such as TP polyester and polyester based alloys due to the availability of dye technology from the textile industry. However, new dyes are under development and the application of the process to more plastics is anticipated. 

About 50% of all industrial dyes manufactured during the last 120 years were produced using this reaction. The terms diazo component and coupling component originated in azo dye technology.

As the coloration with dyes is based on physico-chemical equilibrium processes, namely diffusion and sorption of dye molecules or ions followed by chemical reactions in the substrate, the shade and fastness of a given dye may vary depending on the substrate. The development of new substrates present new problems, give rise to new dyes and dyeing methods and thus influence dyeing technology to a wider scale.
