What chemicals are used to coat various plastic films that create the iridescent effect


GREETINGS: What is/are the chemicals that are used to coat various plastic films that create the iridescent effect? Does the film have an effect on the iridescence? If these questions are out of your area of expertise please let me know where I might go for the info. THANKS

There is actually a kind of film which is called iridescent film. It consists of multilayer of different plastics and by precisely controlling the thickness of each layer and the kind of plastic. It can create a strong iridescent effect. This must be much simpler instead of applying a coating onto the plastic film.
