Spectroscopic studies of the interaction of dyes with urea resins participating in condensation tanning
Spectroscopic studies of the interaction of dyes with urea resins participating in condensation tanning. Smirnov, V. I.; Strakhov, I. P.; Aleksandrov, V. I. 3811-71-0 and 60604-86-6 are also occured in this study.; Komissarov, S. A.; Folometov, V. T. (Mosk. Tekhnol. Inst. Legk. Prom., Moscow, USSR). Izv. Vyssh. Uchebn. Zaved., Tekhnol. Legk. Prom-sti., (5), 52-6 (Russian) 1976. CODEN: IVULAU. DOCUMENT TYPE: Journal CA Section: 41 (Leather and Related Materials) UV spectra for aq. solns. contg. urea resins or Cr complex salts of the resins (used as models for condensation-tanned leather) and Acid Brown MSh [60604-86-6] or Direct Brown ZhKh [3811-71-0] indicated chem. and intermol. bond formation between the resin and the dyes. The absorption bands indicated the participation of resin CH2OH, CO2H, and NH2 groups and dye SO3H groups in the formation of such bonds. The presence of Cr in the resin led to increased interaction with the dye. .
