Definitions
- the present invention relates to photo graphic silver salt emulsions of increased stability, little tendency to fog and determined grain size, to layers containing the same.
- Example 1 In a prescription for the manufacture of a highly sensitive negative-emulsion with use of a gelatine which produces fog, there is added to the gelatine, while itis being digested, 50 milligrams of tetrazole per 100 grams of silver nitrate. There is obtained a highly sensitive, clear emulsion.
- Example Q A highly sensitive negative emulsion is made according to any known prescription and before the silver salt solution is run into the potassium bromide solution there are added to the latter 7O milligrams of 5-methylbenzotriazole per each 100 grams of silver nitrate. There is thus obtained a-clear emulsion of finer grain than when made without the addition of 5-methylbenzotriazole. Y
- a process of manufacturing light sensitive silver halide emulsions of increased stability in which there is added to a constituent of the emulsion at any stage of the manufacture a compound forming a stable silver salt of no higher solubility than silver chloride and containing at least 3 nitrogen atoms in the molecule at least one of which being linked to a hydrogen atom which is liable to substitution by silver.
- a process of manufacturing light sensi tive silver halide emulsions of increased stability and restrained size of silver halide grains in which there is added to a constitu-1 ent of the emulsion prior to the addition of silver nitrate a compound forming a stable silver salt of no higher solubility than silver chloride and containing at least 3 nitrogen atoms in the molecule at least one of which being linked to a hydrogen atom which is liable to substitution by silver.
- a process of manufacturing light sensitive silver halide emulsions of increased stability in which there is added to the emulsion a compound forming a stable silver salt of no higher solubility than silver chlo ride and containing 3 nitrogen atoms in the molecule at least one of which being linked to a hydrogen atom which is liable to substitution by silver.
- a process of manufacturing light sensitive silver halide ei'nulsions of increased stability in which there is added to a constituent of the emulsion at any stage of the manufacture a compound forming a stable silver salt of no higher solubility'than silver chloride and containing 3 nitrogen atoms in the molecule at least one of which being linked to a hydrogen atom which isliable to substitution by silver. 7
- a process of manufacturing light sen sitive silver halide emulsions of increased stability and restrained size of silvergrains in which there is added to a constituent of the emulsion prior to the addition of-silver nitrate a compound forming a stable silver salt of no higher solubility than silver chloride and containing 3 nitrogen atoms in the molecule at least one of which being linked to a hydrogen atom which is liable to substitution by silver.
- Light sensitive silver halide emulsions containing a compound forming a stable silver salt of no higher solubility than silver chloride and containing at least 3 nitrogen atoms in the molecule at least one of which being linked to a hydrogen atom which is liable to substitution by silver.
- Light sensitive silver halide emulsions containing a compound forming a stable silver salt of no higher solubility than silver chloride and containing 3 nitrogen atoms in the molecule at least one of which being linked to a hydrogen atom which is liable to substitution by silver.
- sitive silver halide emulsions of increased stability comprising the step of adding tetrazole to a constituent of the emulsion at any stage of its manufacture.
- Light sensitive silver halide emulsions containin tetrazole.
- Lig t sensitive silver halide emulsions containing tetrazole added to a constituent of the emuls'on at any stage of its manufacture.
