Definitions

• the development accelerators are preferably added in dissolved form in water or in aqueous mixture of water and water-miscible organic solvents that do not impair the photographic properties of the light-sensitive silver halide emulsion.
• the polyaddition products are not sul'ficiently soluble in water in their base form, they are converted into their salt form by neutralization, e.g., with an acid such as sulphuric acid, hydrochloric acid, p-toluenesulphonic acid, or acetic acid.
• the optimum amount of development accelerator added to the silver halide emulsion depends on the very compound, on the nature of the colloid binding agent for the silver halide grains, and on the amount and the kind of the silver halide in the emulsion.
• the development accelerators are added to the light-sensitive material in amounts ranging from mg. to 10 g. per mole of silver halide. In the developing bath they are normally used in amounts ranging from 0.1 g. to 10 g. per liter. If necessary, these compounds can also be added in amounts exceeding these limits.
• This emulsion is divided into several aliquot portions and to the separate portions is added one of the development accelerators according to the present invention.
• the emulsion portions are separately applied to a cellulose triacetate support and dried.
• test strips obtained are then exposed in the same conditions through a grey Wedge and developed for 7 minutes at C. in a fine-grain developer of the following composition:
• the speed is given in relative exposure values in respect of an emulsion to which no sensitizer Was added.
• a decrease of the exposure value of means a doubling of the speed.
• Amount of compound per Sensitometrlc results Number of the kg. of emuladded compound sion Fog Gamma Speed EXAMPLE 2
• An emulsion as described in Example 1 is used, except that the test strips after having been exposed, are developed for 5 min. at 20 C. in a classical fast acting hydroquinone/p-N-methylaminophenol developer of the following composition:

• R is an alkyl group of 1 to 5 carbon atoms, or an aralkyl group
• a photographic light-sensitive silver halide material comprising a polymeric compound containing alkylene (N alkyl) amino alkylene groups linked through hydroxy-substituted oxyalkylene groups and/or such polymeric compounds wherein the hydrogen atoms of said hydroxyl groups are wholly or partly substituted.
• a photographic developing bath for exposed lightsensitive silver halide materials containing from 0.1 g. to 10 g. per liter of a polymeric compound obtained in basic form by polyaddition of a N-alkyl-dialkanolamine and/ or a trialkanolamine with a bis-epoxide or by polyaddition of a N-alkyl-containing bis-epoxide with a diol.
