Imaging Characteristics of Novel Photosensitive Diazo Compounds for Screen Printing

摘要

Imaging Characteristics of Novel Photosensitive Diazo Compounds for Screen Printing The diazo resin which is a condensation product between p-diazo diphenylamine (DPD) and formaldehyde has been used as a photosensitive resist (DRR) for screen printing. As photobleaching of this diazo resin is insufficient, photosensitivity of the thick layer is low.
