Al. Margolin et al., PHOTOSTABILIZATION OF CELLULOSE-ACETATE BY MACROCYCLIC DYES AS A NEW CLASS OF POLYMER LIGHT STABILIZERS, International journal of polymeric materials, 19(3-4), 1993, pp. 201-208
Macrocyclic dyes based on aromatic diamines and phathalodinitrile have
been found to be effective light stabilizers of cellulose acetate. Th
ey act by the mechanisms of UV screening and photosensitization. Its e
ffectiveness depends on the structure of compound.
