Abstract
An optically brightened fishing line consisting essentially of a mixture of one or more nylon polymers and a polymer which is the reaction product of a nylon monomer or polymer and a substituted triazine and coumarin component, the substituted triazine and coumarin component having the structural formula: ##SPC1## The substituted triazine and coumarin component is present in a reactant mixture in the range of from about 0.01 mol up to about 0.25 mol per mol of nylon monomer, with the reactant mixture being treated so as to form a reactant mass which is active in performing a variety of functions when reacted with nylon polymers or mixtures of polymers. Thereafter, the reactant mass is mixed with one or more nylon polymers, with the reactant normally being present in the range of about 0.1 up to about 15% by weight. The triazine-coumarin compound is the coupled product of 7-amino 3-phenyl coumarin and 2-chloro-6 diethylamino-1,3,5-triazine or 7-[2 chloro-6 diethylamino, 1,3,5-triazine 4 yl] amino 3-phenyl coumarin.
