To all who are interested in ED photoresists:

list of manufacturers (taken from Electronic Packaging & Production, Feb
1992/67):
Du Pont, Kansai Paint, MacDermid, Nippon Paint, Nippon Petrochem,
Shipley.

This list might need an update.

We have been using two ED resists so far. Both are manufactured by
Shipley: Neg. resist Eagle 2100 EDPR and Pos. resist PEPR 2400. We use
both resists for Micromechanics applications. In our experience the
negative resist is easier to process.

Regards,
