A tabular silver chloride iodide or silver chloride-bromide-iodide emulsion with a chloride content of at least 90 mol %, an iodide content of 0.01 to 5 mol % and a cubic habit, which is characterized in that with respect to the projected area of all the crystals at least 80% of the crystals have an average aspect ratio of at least 8, a maximum crystal thickness distribution width of 15% and a maximum particle size distribution width of 25%, and which can be produced by a new process, wherein the supersaturation during crystal growth is adjusted within a defined range, is distinguished by high spectral sensitivity and by good stability on storage at elevated temperatures and particularly at high atmospheric humidities.
