Abstract

PURPOSE:To enhance the development accelerating effect of a developer for dry diazo copying, to make the developer suitable for high-speed development and to improve the fading and water resistances, etc. of a copy by adding glycol ether to the developer together with an aqueous ammonia soln. CONSTITUTION:A developer contg. 1-30wt% glycol ether represented by the formula (where R is 1-3C alkyl and n is 1-5) to the amount of an aqueous ammonia soln, having 10-30wt% ammonia concn, is used as a developer for diazo copying paper. A copied image with sufficient density is obtd. at 100-900m/hr developing speed, and the developed copy has superior quality such as superior fading and water resistances.
