Abstract

A mathematical model of the modulation transfer function of silver halide light-sensitive layer which includes dye couplers of DIR (Development Inhibitor Releasing) and DAR (Development Accelerator Releasing) types is presented in this paper. Contemporary methods of the production of colour photographic materials purposely utilize adjacency effect based on the strong, but locally restrained, photographic development As a result of such a mechanism of the photographic image formation from organic dyes, improved quality of the image, especially contour contour and the modulation transfer function were obtained. In order to study both qualitative and quantitative relationships between scattered lights within photographic layers, theoretical model simulating these processes has been developed. The above model enables the analysis of the influence of adjacency effects on the properties of photographic materials when inhibitors of the photographic development of dye components DIR and accelerators of the photographic development of components of DAR types are applied.
