摘要：

The photosensitivity of ten monochlorotriazinyl (MCT) reactive dyes (three monoazo, five disazo, a copper phthalocyanine, and an anthraquinone) was estimated by exposing the binary mixtures of each MCT dye and an aminopyrazolinyl azo dye on cellulose in aerated water. The ease with which MCT dyes were photo-oxidized was examined by use of Rose Bengal. MCT dyes on cellulose dyed in admixture underwent reductive or oxidative fading depending on the own properties and on the conditions of exposure, and sensitized the oxidative fading of the partner dyes at the same time. The concentration dependence of fading for two dyes on cellulose was examined under wet conditions.
