  • Patent number: 6777087
    Abstract: A near infrared-cutting material produced by forming, on a transparent substrate, a transparent resin film containing at least a near infrared absorbing-dye and a dye having a maximum absorption wavelength at 550 to 620 nm, wherein the amount of the solvent remaining in the transparent resin film is 5 ppm by weight to less than 500 ppm by weight; since the amount of the solvent remaining in the transparent resin film containing a near infrared-absorbing dye, etc. is minimized, the long-term stability of the near infrared-absorbing dye, etc. in the film at high temperatures is greatly improved.

  • Publication number: 20010015279
    Abstract: A transparent electromagnetic radiation shield material for placement in front of a display device or other such source of electromagnetic radiation to shield the viewer from electromagnetic radiation while enabling the display to be viewed therethrough is provided, which transparent electromagnetic radiation shield material is produced by the steps of applying to the surface of a transparent base material a resin solution containing a reduction metal, drying the applied solution to form a coating, optionally subjecting the coating to reduction treatment as required, forming an electroless plating layer on the entire surface of the coating while simultaneously blackening the coating, forming a desired resist pattern on the electroless plating layer, and removing portions of the electroless plating layer where no resist is present and blackened portions of the coating thereunder by etching. A metallic salt or a metal complex or particles of a reduced metal particles are used as the reduction metal.

  • Patent number: 5506091
    Abstract: A photosensitive resin composition formed by dissolving a photosensitive resin and a metallic salt or a metal complex in a common solvent or by dispersing reduced metal colloid particles in a photosensitive resin. Also disclosed is a method of forming electrically conductive patterns by applying the photosensitive resin composition to a substrate, pre-baking the resin and then successively subjecting it to exposure, development and post-baking. The result is subjected to electroless plating, directly in the case of the photosensitive resin containing dispersed metal colloid particles, and after reducing the metallic salt or a metal complex to a metal in the case of the photosensitive resin composition containing a metallic salt or metal complex. The reduction of the metallic salt or metal complex is conducted after pre-baking or one of the ensuing steps.
