Abstract
A radiation shielding structure includes a first adhesive layer, a resin layer, and a metal foil laminated sequentially on a release layer of a plastic film. A metal layer pattern is formed from the metal foil. The first adhesive layer, the resin layer, and the metal layer pattern are formed sequentially from the bottom on a transparent substrate by separating the release layer from the first adhesive layer along an interface and then adhering the first adhesive layer to the transparent substrate.
Claims16
A shielding base member comprising, in sequence:
- a transparent substrate;
- a first adhesive layer formed on the transparent substrate;
- a resin layer formed on the first adhesive layer;
- a metal layer pattern formed on the resin layer;
- and
- a reflection preventing layer formed on the metal layer pattern via a third adhesive layer, said shielding base member being produced by the process comprising:
- forming on a release surface of a plastic support film, in sequence, a first adhesive layer, a resin layer, and a metal foil;
- forming a pattern in the metal foil;
- removing the plastic support film by separating the plastic support film at the interface between the release surface and the first adhesive layer;
- and
- then adhering the first adhesive layer, without the plastic support film, onto a transparent substrate to form the shielding base member, wherein the first adhesive layer is in direct contact with the transparent substrate, the resin layer is in direct contact with the first adhesive layer, and the metal layer pattern is in direct contact with the resin layer.
A shielding base member comprising, in sequence:
- a transparent substrate;
- a first adhesive layer formed on the transparent substrate;
- a resin layer formed on the first adhesive layer and having at least a function of absorbing near-infrared radiation in a range of 820 to 1200 nm;
- a metal layer pattern formed on the resin layer;
- and
- a filter layer formed on the metal layer via a second adhesive layer and having at least a reflection preventing function;
- and
- wherein the shielding base member is produced by the process comprising;
- forming on a release surface of a plastic support film, in sequence a first adhesive layer, a resin layer, and a metal foil;
- forming a pattern in the metal foil;
- removing the plastic support film by separating the plastic support film at the interface between the release surface and the first adhesive layer;
- and
- then adhering the first adhesive layer, without the plastic support film, onto a transparent substrate to form the shielding base member, wherein the first adhesive layer is in direct contact with the transparent substrate, the resin layer is in direct contact with the first adhesive layer, and the metal layer pattern is in direct contact with the resin layer.
