摘要

ADHESIVE-COATED COPPER FOIL CHARACTERIZED BY THAT THE ADHESIVE CONTAINS A RESIN CONTAINING ISOCYANURATE RINGS DEFINED AS WHERE R REPRESENTS ONE OF THE FOLLOWING SUBSTITUENTS A TO F: AND DOES NOT CONTAIN MELAMINE RESIN. SPECIFICALLY, THE ADHESIVE COMPRISES 5 TO 50 PARTS BY WEIGHT OF A RESIN CONTAINING ISOCYANURATE RINGS, 10 TO 50 PARTS BY WEIGHT OF POLY(VINYL ACETAL) RESIN, 5 TO 40 PARTS BY WEIGHT OF EPOXY RESIN, AND 1 TO 50 PARTS BY WEIGHT OF BLOCKED ISOCYANATE RESIN. THIS ADHESIVE HAS BOTH A GOOD ANTI-TRACKING PROPERTY AND A HIGH ACID RESISTANCE. THE ADHESIVE-COATED COPPER FOIL OF THIS INVENTION IS PREPARED BY FORMING AN ADHESIVE LAYER ON COPPER FOIL. COPPER-CLAD LAMINATE MANUFACTURED USING THIS COPPER FOIL IS SUITED TO CIRCUIT BOARDSF6R HIGH VOLTAGE CIRCUITS AND CAN SOLVE PROBLEMS CAUSED BY A LOW ETCHANT RESISTANCE.
