It occurs to me that in photo silkscreening you apply an emulsion (Diazo)
to the screen, let it dry, and expose a negative to UV. Water is used to
wash off the unhardened emulsion. Does anyone know what chemistry is used
in this type of emulsion/sensitizer?

How similar is it to Dichromate processes?

If it's different could these chemicals be used as an alternative?

Thanks!!
