Abstract:

Diazo sensitized gelatins are photosensitive recording materials that unlike dichromated gelatin have a long shelf life. Because of their stability, the diazo emulsions have replaced the dichromated colloids used in the photolithographic field and enabled commercialization of presensitized printing plates. We have produced plane wave gratings with peak efficiencies near 67 at an exposure of 625 mJsq cm and a recording wavelength of 488.0 nm in one diazo recording material. Called diazo salt sensitized gelatin, the photosensitive material produces gratings in gelatin by a complex process that we found not to be a function of exposure. The methods used are described.
