The invention is directed towards methods and compositions for making and using fluorescent monomers which are synthesized by reacting a substituted or non-substituted benzoxanthene anhydride with an amine and with a moiety containing a polymerizable group. Such monomers are useful for the preparation of tagged treatment polymers. Such tagged treatment polymers are useful as scale inhibitors in industrial water systems.
