PURPOSE:To obtain a new benzotriazole fluorine derivative suitable as a rust- proofing, lubricating, water-repelling and oilrepelling agent for the surface of metals, polymeric materials and inorganic materials, especially as a copper foil treating agent for copper-clad laminated board for printed circuit, etc. CONSTITUTION:This new benzotriazole fluorine derivative is expressed by formula I [R<1> is group of formula II (R<2> is F or trifluoromethyl; (n) is 1-15)], e.g. a derivative of formula III. The derivative can be produced by dropping (A) 0.1-1.0mol of a 1,2-epoxypropane compound of formula III (preferably 3- perfluorooctyl-1,2-epoxypropane, etc.) to (B) a solution of 1mol of benzotriazole in dimethylformamide, etc., and reacting at about 100-150 deg.C for about 10min to 6hr. |
