• The diazonium salts of various polycyclic chromogens were used as a polymeriz ation initiator for vinyl monomers according to the procedures reported in the preceding paper. A new type of light-fast coloring agents has thus been prepared through chemical combination of a polycyclic chromogen with a resin. They can not again be separated into chromogen and resin moieties by fractional precipitation or extraction. X-Ray diffraction patterns and electron microscopic photographs indicated that the coloring agents were in the forms of ultrafine dispersion andwere of no definite crystalline form. They showed properties including, lightfastness comparable to that of copper phthalocyanine coloring agents.
