Abstract
A process for bonding metal directly to thermoplastic polymeric base materials and a process for producing printed circuits from such metal clad thermoplastic polymeric base materials are provided. The invention also includes the articles so produced. Metal clad thermoplastic polymeric base materials are produced by laminating a metal foil or sheet to thermoplastic polymeric base material, under pressure, at a temperature from about 2.degree. C. to about 45.degree. C. above the glass transition temperature (Tg) of the thermoplastic. The polymeric material is free of volatile materials such as moisture or solvents when laminated.
