POLYCHROMATIC IMAGING ON THE BASIS OF COLLOIDAL SILVER PARTICLES ON HALOGEN SILVER PHOTOGRAPHIC LAYERS

The possibility of polychromatic imaging on the monodispersed AgHal ph oto layers with low silver content (about 1 g/m2) is shown. The effect is reached by treatment of the exposed layer in the developing-fixing solution (monobath) with the thiocyanate ion as a ligand in which the physical development via the solution is realized. The polychromatic image consists of compact spheroidal silver particles with sizes depen d on exposure. General regularities of formation and properties of the image as well as the possibilities of controlling the size, shape, co ncentration of the silver particles forming the image and, therefore, the spectral and color characteristics of the latter one arc discussed .
