Abstract (en)
[origin: WO8201944A1] New diazotype materials of which the sensitive layer contains as a base generator a compound comprising a base portion and an acid portion, the acid portion being a carboxy-2 carboxamide group, the base portion consisting of an alcaline or alcaline-hearth cation or a tetraalkylamonium cation. These diazotype materials develop quickly and have an excellent fastness to ageing.
