| titleOfInvention | Black-color forming two-component type diazo copying material |
| abstract | A two-component type diazo copying material according to this invention, which comprises a support and a photosensitive layer formed thereon, said layer consisting essentially of a diazo compound expressed by the following general formula I and a coupler mixture consisting of a compound expressed by the following formula II, a compound expressed by the following general formula III and a compound expressed by the following general formula IV, can form a genuine black-color image and is especially optimum for preparing a secondary original used in electrophotographic copying machines. General formula I <IMAGE> (wherein R represents alkyl radical having 1 to 5 carbon atoms; R1 and R2 represent substituted or non-substituted alkyl radical, aralkyl radical or cycloalkyl radical, or R1 and R2 may form a heterocyclic ring together with the nitrogen atom to which they bond; and X represents anion.) Formula II <IMAGE> General formula III <IMAGE> (wherein X is of no account or represents O, S, SO or SO2.) General formula IV <IMAGE> [wherein R3 represents hydrogen, alkyl radical having 1 to 4 carbon atoms or halogen; R4 represents hydrogen, -(CH2)nOH (wherein n is an integer ranging from 2 to 4) or <IMAGE> (wherein n is an integer ranging from 2 or 4; R5 and R6 represent alkyl radical having 1 to 4 carbon atoms, or R5 and R6 may form heterocyclic ring together with nitrogen atoms to which they bond. |
