    摘要： Disclosed are 4-(N,N-dialkylamino)aniline compounds having a 4-N substituent which is a polyethyleneoxy group and which forms a condensed ring with benzene ring, such as aniline compounds having the following structure, a processing composition containing such a compound and a method for forming a color image with the processing solution. The aniline compound is useful as a color developing agent capable of having a low fog density and sufficient yellow and cyan image densities and suitable for the rapid process.

    摘要： Novel N-substituted halogenomethyleneindoxyls [N-substituted halogeno-(3-oxa[2H]indol-2-ylidene)-acetic acids] and a novel process for their preparation by reacting N-substituted anilides with dihalogenomaleic anhydrides or derivatives thereof are described. The novel N-substituted halogenomethyleneindoxyls are valuable intermediates for the preparation of pharmaceutical active compounds having an antiallergic action.
