METHOD OF MANUFACTURING METALLIC PATTERN

摘要

A metallic foil is laminated to a transparent substrate with a photopolymerizable adhesive. An outer layer of photoresist is used in etching a pattern in the foil. The etched foil itself is then used as a resist in the complete removal of the uncovered portions of the adhesive, leaving the transparency of the revealed substrate material totally unimpaired. Finally, the remaining adhesive is hardened by polymerization resulting from exposure to ultraviolet light passed through the substrate from the unlaminated side.
