PROCESS FOR THE PRODUCTION OF PHOTOGRAPHIC IMAGES BY MODIFYING VESICULAR IMAGES

Photographic images are produced by forming in a light-sensitive photographic layer a vesicular image which subsequently is transformed by treatment with a swelling agent for the binder into a stable image consisting of differences in the refractive index; the latter image can be made visible by sui...

Zusammenfassung:Photographic images are produced by forming in a light-sensitive photographic layer a vesicular image which subsequently is transformed by treatment with a swelling agent for the binder into a stable image consisting of differences in the refractive index; the latter image can be made visible by suitable optical means.
