Good replacement for Zeon ZEP520A.

  

Contrast curves for different developers

These diagrams show the contrast for different developers, i.e. the ratio of resist thickness before and after development for exposed areas.
"D" is resist thickness after exposure, "D0" is resist thickness before development.
Here contrast is called "gradation".
