The azomethine dyestuffs prepared in gelatine layer chromogeneous development of the couplers based on 4,4-dimethyl-3-oxo-N-phenylpentanamide (I to XVII) and 4,4-dimethyl-3-oxo-N-(sulphamoylphenyl)pentanamide (XXI to XXVII) have been found to have be

For quantitative studies of photochemical reactions with low quantum yields the paper suggests application of polychromatic radiation sources whose overall intensity is by orders higher than that of currently available monochromatic sources. The more

Photolysis of 1,2-naphthoquinone-1-diazide and 9,10-phenathrenequinonediazide in cyclohexane gives coloured products decomposing on further irradiation. Formation of the products and their concentration depends on the way of irradiation (short, conti

Besides population and relaxation of T1 state of methylene blue in methanolic solution it has been possible to observe increase and decomposition of a transient with longer lifetime which is probably a triplet excimer of the dyestuff. Kinetic measure

The photolysis of 9,10-phenanthrenequinonediazide and 1,2-naphthoquinonediazide derivatives was studied; the spectral changes occurring during the photolysis and the quantum yields for various excitation wavelengths were measured, the order of the re

A series couplers have been prepared on the basis of 4,4-dimethyl-3-oxo-N-phenylpentaneamide. Some of them have been converted into the respective azomethine dyestuffs the absorption maxima of which have been compared with those of the corresponding
