Embodiment 1-1

[0419] (Silver halide photosensitive material)

[0420] An emulsion was prepared containing 10.0 g of gelatin relative to 60 g of Ag and silver iodobromide particles (I = 0.2 mol %, Br = 40 mol %) containing corresponding spheres with an average diameter of 0.1 μm in an aqueous medium.

[0421] In this emulsion, adding K 3 Rh 2 Br 9 and K 2 IrCl 6 , to get a concentration of 10 -7 mol / mol of Ag, thereby doping the silver bromide grains with Rh ions and Ir ions. To this emulsion, add Na 2 PdCl 4 , gold-sulfur sensitization using chloroauric acid and sodium thiosulfate. Next, the emulsion was coated on polyethylene terephthalate (PET) with a gelatin film hardener so that the silver coating amount was 1 g / m 2 . In this step, adjust the Ag / gelatin volume ratio to 1 / 2.

[0422] The emulsion was coated on a portion of a PET support having a width of 30 cm (width 25 cm, length 20 m). Both ends (3 cm) of the support were cut off while keeping the coated central portion (24...

Embodiment 1-2

[0458] As an example of "(3) Mesh obtained by etching method using photolithography" cited in the background art section, a metal mesh disclosed in JP-A-2003-46293 was produced.

[0459] Compared with Example 1-1, it was confirmed that uniform surface resistivity was obtained by forming the continuous pattern of the present invention, indicating the effectiveness of the present invention.

Embodiment 1-3

[0461] Sample C was fabricated as in Sample A of Example 1-1, but exposed using rotating polygon mirror scanning laser exposure, scanning at angles of 45° and -45° relative to the silver halide photosensitive material transport direction to form a continuous pattern. When sample C was compared with sample B, the same results as in Example 1-1 were obtained.

Abstract

A light transmitting conductive film formed by patterning a conductive metal section and a visible light transmitting section on a transparent supporting body is characterized in that the conductive metal section is formed of a 1-40[mu]m mesh-like fine wire, and the mesh pattern is continued for 3m or more. A method for manufacturing a display filter whose edge sections of at least two facing sides are mesh-like. In the method, an electromagnetic shield material (C) wherein a mesh-like geometrical pattern conductive layer (B) is continuously formed in a machining direction of a polymer film (A) on the polymer film (A) is used to cut the mesh-like section.

Description

technical field [0001] The present invention relates to a translucent conductive film. In particular, the present invention relates to an electromagnetic wave shielding material capable of shielding electromagnetic waves from radiation such as a cathode ray tube (CRT), a plasma display panel (PDP), a liquid crystal display device, an electroluminescence (EL) display device, or a field emission display device ( Electromagnetic waves generated by the display front of FED), microwave ovens, electronic devices, printed circuit boards, etc., and have light transmission, and manufacturing methods thereof. The present invention also relates to a method of manufacturing a display filter, the display filter thus obtained, and an electromagnetic wave shielding material used therein. More specifically, the present invention relates to a method of manufacturing a display filter containing an electromagnetic wave shielding material capable of blocking electromagnetic waves generated from ...
