Abstract
In order to clarify the nature of the interaction of the dye with silver halides, the adsorption of chloride, bromide and iodide of 2,2’-quinocyanine to silver chloride, bromide and iodide has been studied from various viewpoints. Adsorption isotherms, values of heat of the adsorption and of the saturation maximum of the adsorbed dyes. X-ray diffraction of dyed silver halides, and IR and visible absorption spectra of the adsorbed dyes have indicated that the dye interacts with the surface of silver halides by van der Waals’ forces and electrostatic ones.Keywords
