Adhesiveness revised manner null of polymer material to metal

摘要

PROBLEM TO BE SOLVED: To provide a method for improving the adhesion of a polymeric material to metallic surfaces, which is suited in manufacturing multi-layer printed circuits.;SOLUTION: This method for improving the adhesion of a polymeric material to metallic surfaces comprises (a) bringing an adhesion accelerating composition comprising (1) an oxidizing agent, (2) an acid, (3) a corrosion-resistant agent, (4) a benzotriazole having an electron-withdrawing group having stronger electron-withdrawing power than hydrogen group at the 1-position, and as an optional component, (5) at least one adhesion reinforcing seed source selected from the group consisting of a molybdate, a tungstate, a tantalate, a niobate, a vanadate, an isopolyacid and a heteropolyacid respectively of molybdenum, tungsten, tantalum, niobium, and vanadium into contact with a metallic surface, and then joining a polymeric material to the metallic surface.;COPYRIGHT: (C)2001,JPO
