Looking for a Solvent to Dissolve Diazo Resin? Suggestions?

[Kawakaze]

I am looking for a solvent that can dissolve photo setting resin after it has been hardened. I think it is Diazo resin or something like it. Can anyone suggest something? Thanks!

I don't know if this will help but have you tried simple solvents like chloroform or THF? If they don't work can you try to dissolve it by using these solvents at elevated temperature?
