摘要

Process for the manufacture of a heat-developable diazotyping material, in which a layer of two-component photosensitive diazotyping is applied to a gas-permeable carrier and, on the opposite side of the carrier, a layer which, when heated, yields a volatile base, characterized in that a back layer is applied consisting of two layers, of which the inner layer, which rests directly on the carrier, contains as substantial components, at least one water-soluble acid amide, derived from ammonia or a volatile amine, and a binder, while the outer layer contains at least one strong inorganic base, relatively sparingly soluble in water, and a binder.
