内部潜像乳剤における露光照度と減感剤の影響

抄録

The effect of exposure intensity, desensitizing effect of phenosafranine, light developable and direct print-out characteristics on internal latent image emulsion have been studied.
In low intensity exposure, internal latent image was largely formed, but surface latent image was hardly formed. In high intensity exposure, however, surface latent image also was formed. The variation of the ratio of internal to surface speed on this emulsion by difference of exposure intensity showed a opposite tendency against conventional emulsion.
On the addition of phenosafranine, degree of desensitization was especially effective for surface latent image. This desensitizing effect showed too a opposite tendency against conventional emulsion. Desensitizer, phenosafranine, influenced light developable and direct print-out characteristics as well.
