Abstract
1376443 Photographic emulsion AGFAGEVAERT 2 May 1972 [11 May 1971] 14224/71 Heading G2C A gelatine silver chloride or chlorobromide emulsion in which at least some the the halide crystals have (110) crystal planes is prepared in the presence of a crystal form-modifying agent. (Perfect (110) plane crystals are of regular rhombododecahedral shape). The agent may have the property of enhancing the intensity of the absorption band characteristic of the non- aggregated form of a dye present in an aqueous solution partly in aggregated and partly in non- aggregated form. It may also be a fog-inhibiting or stabilizing agent or an intermediate in the preparation of a spectral sensitizing agent. Specified agents include substituted benzimidazoles and benzthiazoles. The agent may be present during nucleation, crystal growth, physical ripening or replacement of one halide by another. 10-50 millimoles of agent per mole of silver halide may be employed. The emulsion may be formed by the single or double jet method. The emulsion enables higher chemical sensitization without objectionable fog formation.
