Title: Process for developing a two-component diazotype material on a non-metallic carrier, which material can be developed by the influence of heat

Abstract: This invention relates to an improvement in the process for developing a two-component diazotype material on a non-metallic carrier and which can be developed by the influence of heat, and contains, in particular, compounds which can be decomposed under the influence of heat and produce in this process an alkaline environment, the heat influence being produced by electromagnetic radiation radiated from a power transmitter, the improvement comprising subjecting the diazotype copying material to microwave radiation with a frequency higher than 10.sup.9 Hz without a heat-generating body being placed between the power transmitter and the diazotype material. The invention also relates to a developing device for developing the diazotype material.
