抄録
In the previous paper it was shown that aminoanthraquinones gave corresponding anthrahydro-quinone by exposure to the light in ethyl alcohol.<br>The present paper deals with the effects of several compounds on the rate of the fading reaction of 1, 4-bisoctylaminoanthraquinone. The compounds in with similar chemical constitution to textile materials were sellected, such as ethyl acetate (I), 1, 3-propanediol (II), propylene trimer (III) and n-hexane (IV).<br>Spectral changes of the dye due to light exposure in ethyl alcohol, adding to which one of the compounds, were measured in the visible region.<br>Following results were obtained:<br>a) In irradiation of the dye solution, new band of the spectrum having maximum at 500_??_460mμ revealed as shown in earlier report. The rats of fading reaction was remakably accelerated by the addition of the compounds I and II.<br>b) In addition of the compound III no spectral change was observed except the reduction of optical densities, and the rate of the reaction was not modified.<br>c) In addition of the compound IV the rate of fading reaction decreased. Also, developement of the new band by light sxposure in n-hexane was obserbed at 600_??_560mμ.<br>This intermediate product was identical in the spectra with 1, 4-diaminoanthraquinone and its melting point was not depressed by mixing with synthesized 1, 4-diaminoanthraquinone.
