ABSTRACT:
Method and apparatus for the metallization of support members, such as paper sheeting and other cellulosic products. A metallic film is transferred to a preheated paper support from a plastic sheet carrier and adhered to the paper by a thermoplastic material. The carrier is typically of stabilized plastic with a releasably adhered film of metal. Separate metallic films may be transferred simultaneously from opposite sides of a preheated plastic sheet carrier to separate, preheated paper supports. Pressure is applied to the composite which is cooled, desirably by chilling, and the carrier stripped away to leave the desired metallic layer on the receiving surface of the paper support.
This transfer procedure overcomes the objections associated with metal foil laminates and is particularly suitable for metallizing support members, like paper, which are difficult to metallize directly because they release significant amounts of vapor during conventional vacuum metallization. The results are also superior to what is realized using an adhesive with dispersed metal particles, and the need for curing the adhesive is eliminated.
