The effect of concentration on the photofading rates of two yellow azo acid dyes (C.I. Acid Yellow 135 and C.I. Acid Brown 226) has been examined in nylon-6,6 film and compared with the influence of the dyes on the photochemical oxidation of the polymer using u.v. absorption and viscometric analysis
Akstraet--Fluorescence analysis of nylon-6,6 polymer indicates the presence of a number of chromophoric species. One of the main species has excitation maximum at 290 nm with a corresponding emission maximum at 326 nm and is extractable from the polymer by 2-propanol; another has an excitation maxim
The photofading rates of three azo acid dyes (C.I. Acid Blue 62, C.I. Acid Yellow 135 and C.I. Acid Red 266) and four azo acid metal complex dyes (C.I. Acid Brown 226, C.I. Acid Blue 171, CL Acid Orange 162 and C-1. Acid Black 107) were examined in nylon 6,6 film and were compared with the influence
