Diazotype photographic copying material adapted for wet development and for producing copied image in black color |
| abstract |
A two-component diazotype photographic copying material for wet development and having a light-sensitive layer which contains at least one light-sensitive aromatic diazo compound and also contains at least one each of the three kinds of coupling components which are adapted to form a blue dye, a bluish-violet dye and a yellow dye, respectively, when said coupling components are made to react with said diazo compound, is capable of providing a copied image in a very clear black color when developed with an alkaline aqueous solution containing no coupling component. |
