Description and Uses

Novel mordent and disperse azo dyes were prepared by the coupling of various diazo solutions of aromatic amines with 2, 4-dihydroxybenzophenone. The ultraviolet absorbing monomers were synthesized by reaction of 2, 4-dihydroxybenzophenone with glycidyl acrylate and glycidyl methacrylate. Two new polymerizable stabilizers, 4-benzoyl-2-(α-piperidino-2-chlorobenzyl)-3-hydroxyphenyl acrylate (BPBHA) and corresponding methacrylate (BPBHMA), were synthesized and characterized from 2,4-Dihydroxybenzophenone. a polymerizable UV-stabilizer, 2-hydroxy-4-(3-methacryloxy-2-hydroxylpropoxy) benzophenone (BPMA), was synthesized using 2, 4-dihydroxybenzophenone (UV-0) and glycidyl methacrylate (GMA).
