    摘要： A process for the production of optically isotropic extrusion films is disclosed. Accordingly in a first process step a thermoplsatic resin is extruded to form a film having a thickness below 600 .mu.m. The second process step entailsa) calendering said film between a ground elastic roller and a high gloss steel roller to produce a film having a high gloss surface and a matt surface, orb) calendering said film between a lacquered elastic roller and a high gloss steel roller to produce a film having high gloss on both surfaces, orc) calendering said film between a ground elastic roller and a high gloss steel roller to produce a film having a high gloss surface and a matt surface, and then coating said matt surface with a melt of said thermoplastic polymer and calendering the resulting coated film between a high gloss steel roller and a ground elastic roller, with the high gloss side of the coated film facing the roller of elastic material.

    摘要： A method for manufacturing printed electrical circuits which comprise a substrate and copper foil applied thereto by hot embossing in a predetermined circuit pattern, said method comprising(a) providing a laminate which comprises the sequence of a printed circuit substrate, a heat activated adhesive layer, a copper foil and a carrier film which is electrically conductive,(b) passing an electrical current between two electrodes and through the carrier film wherein one electrode has sufficiently large film contact area whereby substantially no resistance heating results from the current density and the other electrode serves as an embossing tool and is of sufficiently small film contact area whereby sufficient resistance heating results from the current density to activate the adhesive layer to bond the copper foil to the substrate in the pattern of said other electrode, and(c) removing from the laminate the carrier film and such copper foil overlying areas where the adhesive was not heat activated thereby leaving a copper foil pattern bonded to the substrate.
