DIAZOTYPIEMATERIAL

This invention relates to an improvement in a diazotype material comprising, in the light-sensitive layer, a diazo component and a coupling component which yields a black dyestuff image, the improvement that the diazo component is a 2,5-dialkoxy-4-morpholino-benzene diazonium salt and the coupling c...

Zusammenfassung:	This invention relates to an improvement in a diazotype material comprising, in the light-sensitive layer, a diazo component and a coupling component which yields a black dyestuff image, the improvement that the diazo component is a 2,5-dialkoxy-4-morpholino-benzene diazonium salt and the coupling component is a combination of (a) 6-methoxy-2-hydroxy-3-naphthoic acid-N( omega -aminoalkyl)-amide as a blue coupler, (b) a 2-alkyl- or 2-aryl-1,3-dihydroxybenzene or a cyanoacetoamide as a yellow coupler, and (c) at least one compound of the general formula wherein X is zero, =S, =SO, or =SO2, as a reddish-brown coupler, the molar ratio of blue coupler to yellow coupler being in the range of about (0.7 to 0.9):1, and the molar ratio of blue coupler to reddish-brown coupler being in the range of about (6 to 12):1.
