ON THE SYNTHESIS AND PHOTOSTABILITY OF SOME NEW NAPHTHALIMIDE DYES

Abstract Seven new 1,8-naphthalimide dyes, containing a hindered amine stabilizer in their molecule, have been synthesized. The properties of the dyes and their photostability in solution, in polymer and on polyamide fabrics were studied. The influence of the dyes on the photostability of PMMA coloured “in-mass” was examined.
