Electrophotographic light-sensitive materials

Many other applications have been described for these compounds and the hst is so extensive that it is impossible to cover each example here. Nevertheless, it is noteworthy that appropriately substituted 4-arylidene-5(4r/)-oxazolones, for example, 359 and 360 have been reported as organic Iruninophores" " and electrophotographic light-sensitive materials," respectively. The use of apoca-rotenoid derivatives such as 362 as monomolecular films has also been described." For new materials, a number of water-insoluble oxazolones have been used for dyeing or printing synthetic fibers" and, in this context, 4-(pyren-1-ylmethylene)-2-substituted-5(4/i/)-oxazolones 357, prepared from pyrene-1-carboxaldehyde, have...
