Abstract
1350876 Holography AGFA-GEVAERT AG 25 April 1972 [28 April 1971] 19133/72 Heading G2X Phase holograms are prepared by holographically exposing a light-sensitive silver halide emulsion, developing in a non-tanning developer, oxidizing the silver image produced in a bleaching bath to give a silver compound which is dissolved out of the layer. Preferably the exposed emulsion is developed with a hydroquinone, 1-phenyl-pyrazolidone-3 or p-aminophenol developing agent, treated in a short stop bath of aqueous acetic acid, bleached in aqueous K 2 G 2 O 7 /H 2 SO 4 , clarified in aqueous Na 2 SO 3 , washed, dried and desensitized in a solution of desensitizer in an alcohol (e.g. an aqueous ethanolic solution of phenosafranine, glycerol and KBr) and rinsed with alcohol.
