Synthesis of polymerizable 1,8-naphthalimide dyes containing hindered amine fragment

The synthesis of new 1,8-naphthalimide dyes, containing hindered amine stabilizer fragment is reported. Two polymerizable dyes, a combination between 1,8-naphthalimide and 2,2,6,6-tetramethylpiperidine, as well as three 1,8-naphthalimide intermediates were synthesized in good yields under variable reaction conditions. The ability of the dyes for co-polymerization with vinyl monomers such as acrylonitrile was demonstrated.
