Photosensitive Emulsion

The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased.

Emulsion, Photosensitive


any of the photographic preparations consisting of substances suspended in colloidal binders. Emulsions are coated on supporting plates and dried; during processing, they swell when immersed in cold water but do not dissolve. Photosensitive emulsions contain microcrystals of silver halides (except AgF) and such other substances as diazo compounds and chromium salts. These compounds are uniformly dispersed, primarily in gelatin, but to a lesser extent in cellulose nitrates, albumin, polyvinyl alcohol, and other colloids. In addition to the dispersed compounds, photosensitive emulsions contain small quantities of such additives as optical sensitizers, hardeners, and stabilizers.

It had properties that suited the purpose of providing a base for the photosensitive emulsion: it was lightweight, flexible, transparent, durable, and would not combine with the chemicals used in photo processing.
Given the size of the beams recorded, this also required the development of very fine grain, high resolution silver halide photosensitive emulsions. Denisyuk worked with Rebekka Protas, a colleague at the Institute, to develop an emulsion with a sensitivity improved 1000 times, and a much smaller grain size.
