PCT No. PCT/FR81/00151 Sec. 371 Date Jul. 30, 1982 Sec. 102(e) Date Jul. 30, 1982 PCT Filed Nov. 19, 1981 PCT Pub. No. WO82/01944 PCT Pub. Date Jun. 10, 1982.The invention relates to new diazotype materials of which the sensitive layer contains, as a base generator, a compound comprising a basic part and an acid part, the acid part being a 2-carboxycarboxamide group and the basic part consisting of an alkali metal cation or alkaline earth metal cation or a tetraalkylammonium cation. These diazotype materials develop rapidly and possess an excellent resistance to ageing.
