摘要:
A silver salt-containing layer containing a silver salt and provided on a support is exposed and developed to form a metal silver portion and a light-transmitting portion, and then the metal silver portion is further subjected to physical development and/or plating to form a conductive metal portion consisting of the metal silver portion carrying conductive metal particles. A method for producing a light-transmitting electromagnetic wave-shielding film which enables production of an electromagnetic wave-shielding material simultaneously having high EMI-shielding property and high transparency in a fine line pattern and also enables mass production of such films at a low cost, and a light-transmitting electromagnetic wave-shielding film obtained by the production method and free from the problem of moire are provided.
摘要:
An etching composition, particularly for kinetically controlled etching of copper and copper alloy surfaces; a process for etching copper and copper alloys, particularly for etching at high rates to provide uniform and smooth, isotropic surfaces; an etched copper or copper alloy surface obtained by the process; and a process for generating copper or copper alloy electrical interconnects or contact pads. The etching composition and etching processes provide a smooth, isotropic fast etch of copper and copper alloys for semiconductor fabrication and packaging.

The present invention provides a diffusion transfer heat-developable color photographic light-sensitive material comprising a support having thereon at least one light-sensitive silver halide emulsion layer and a nondiffusing dye-providing compound which releases or forms a diffusive dye in response to or in counter response to a reaction by which a silver halide is reduced to silver under the presence of a reducing agent, and an organic solid pigment in at least one of light-sensitive silver halide emulsion layer and the layer(s) adjacent thereto, and a method for forming a color image using the light-sensitive material.
摘要:
A process for photo-plating only a light-irradiated portion of a dye layer formed on a substrate comprises: forming a dye layer on the surface of a substrate; immersing the substrate with the dye layer into an electroless plating solution comprising a sacrificial reagent for supplying electrons by irreversible oxidative decomposition, and at least one of copper ions, nickel ions, cobalt ions, and tin ions; and irradiating the surface of the dye layer with light having an energy higher than the excitation energy of the dye in the dye layer. A thick coating containing at least one of copper, nickel, cobalt, and tin can be formed with excellent adhesion strength only on the light-irradiated portion of the dye layer formed on the substrate.

摘要:
A dielectric layered sequentially processed circuit board is disclosed. A first photodefinable resin containing an electroless plating catalyst is disposed on a substrate and portions of the substrate are exposed through the first resin. A second photodefinable resin absent the electroless plating catalyst is disposed on the first resin, and portions coincident with the exposed portions of the substrate as well as portions of the first resin are exposed through the second resin. A conductive material is deposited on the exposed portions of the substrate and the exposed portions of the first resin.
摘要:
A light-stable physical developer comprising a solution of silver ions, a desensitizing agent and a reducing agent. A method for the detection of one or more components of an aggregate formed between at least one specific binding agent and its corresponding bindable substance by labelling at least one component of said aggregate with a marker and contacting said aggregate with said light-stable physical developer, whereby under influence of the marker a metal particle is formed which can be detected. Further the invention also relates to products, e.g. a test-kit adapted for carrying out the above mentioned method.
