Abstract (en)
The invention concerns a monodisperse emulsion with improved sensitivity. The emulsion of the invention is sensitized with sulphur and gold, and a quantity of thiocyanate of between 0.1 and 1.0 mole per mole of silver is added thereto. A sensitisation level equivalent to that of a corresponding polydisperse emulsion can be obtained.
