Ultraviolet ray hardening water resin attaching copper foil, ultraviolet ray hardening water resin attaching copper-clad laminate, removal modulo null of those manufacturing methods and those hardening

摘要

PURPOSE:To prevent the occurrence of flaws, adherence of foreign matters, discoloration, and the like on the metal foil surface, moreover, enable them to be removed readily by water or the like by providing a cured coating of ultraviolet cured water base resin on the surface of metal foil. CONSTITUTION:A solution of UV curing water base resin solved into water being unsaturated polyamide ether containing a UV curing initiator is applied on the luster surface side of electrolytic foil by a roll coater method for forming a coated film thereon. In the next place, irradiation is effected thereon by means of a UV irradiation device equipped with high pressure mercury lamps, as a result, copper foil is obtained which has a cured film of being 0.1-200mum. And, the copper foil with cured film obtained and prepreg with epoxy resin infiltrated into glass cloth are laminated and molded, thereby obtaining an epoxy resin copper coated laminate sheet. The copper foil and copper coated laminate sheet enable the cured film to be separated and removed readily by solution hydroxide or alkali solution.
