Problems solved by technology

When a pattern having a component in a one-dimensional direction is installed on a window glass of a vehicle as a heating element, there is an effect of aggravating uneven heat generation in a plane due to disconnection (disconnection)
In a pattern having a component in a two-dimensional direction, the irregularity of the wiring becomes stronger, and the wiring pattern becomes easier to see, that is, there is a problem that the visibility of the wiring is significantly deteriorated (wiring visibility)
[0006] The above-mentioned Japanese Patent Laid-Open No. 2009-137455 has a regular wiring pattern having components in two-dimensional directions. Therefore, when it is applied to a window glass of a vehicle, the expansion of

Embodiment

[0218] Hereinafter, the present invention will be described more specifically with reference to examples of the present invention. In addition, the material, usage-amount, ratio, processing content, processing order etc. which are shown in the following Example can be changed suitably unless it deviates from the summary of this invention. Therefore, the scope of the present invention should not be limitedly interpreted to the specific examples shown below.

no. 1 Embodiment

[0220] (Silver halide photosensitive material)

[0221] An emulsion containing 10.0 g of gelatin relative to 60 g of Ag in an aqueous medium containing silver iodobromochloride particles (I=0.2 mol%, Br=40 mol %) having an average spherical equivalent diameter of 0.1 μm was prepared.

[0222] Additionally, adding K to this emulsion 3 Rh 2 Br 9 and K 2 IrCl 6 , so that the concentration is 10 -7 (mol / mol silver), Rh ions and Ir ions are doped in silver bromide grains. Add Na to this emulsion 2 PdCl 4 , and then use chloroauric acid and sodium thiosulfate to carry out gold-sulfur sensitization, and then apply it to polyethylene terephthalate (PET) together with gelatin hardening agent, so that the coating amount of silver is 1g / m 2 . At this time, the Ag / gelatin volume ratio was 1 / 2.

[0223] On a 30 cm wide PET support body, 20 m of width of 25 cm was applied, and both ends were cut off by 3 cm to leave 24 cm of the coated central part to obtain a roll-shaped silver...

no. 2 Embodiment

[0260] Next, adjust Figure 4 ~ Figure 6 In the pattern forming process shown in , various changes are made to the ratio (L1 / L2) of the length L1 of the first side to the length L2 of the second side of the closed area (quadrilateral), and six kinds of patterns are obtained in the same manner as in the first embodiment. Conductive film (samples 1 to 6). The details of samples 1 to 6 are as follows: Figure 11 As shown, the ratio (L1 / L2) of sample 1 is 1, the ratio (L1 / L2) of sample 2 is 2.5, the ratio (L1 / L2) of sample 3 is 5, and the ratio (L1 / L2) of sample 4 is 10 , the ratio (L1 / L2) of sample 5 is 50, and the ratio (L1 / L2) of sample 6 is 100.

[0261] About samples 1-6, the sensory evaluation of the diffraction image and wiring visibility was performed by 4 evaluators. The evaluation results are shown in Figure 11 . Figure 11 In the graph of , the horizontal axis represents the ratio (L1 / L2), and the vertical axis represents the evaluation score. The evaluation resu...

Abstract

The invention relates to a conductive film, a transparent heater, an image forming method and a recording medium. The conductive film (10) comprises plural conductive parts (14) and plural opening parts (16). Each conductive part (14) comprises a main line pattern (22) and plural auxiliary lines (24). The man line pattern (22) is formed by arranging plural wave-shaped lines (21) formed along a first direction on a second direction that is perpendicular to the first direction. Adjacent wave-shaped lines (20) are electrically connected through the plural auxiliary lines (24). The opening parts (16) are formed by parts that are divided by the wave-shaped lines (20) and the auxiliary lines (24). In the main line pattern (22), the at least cycle of the wave lines forming each wave-shaped line is irregular.

Description

technical field [0001] The present invention relates to a conductive film, a transparent heat generating body provided with the conductive film, a pattern forming method suitable for forming a wiring pattern of the conductive film, and a recording medium on which the pattern forming program is recorded, and the conductive film can be used as a vehicle Parts of defrosters, car window glass, etc. can also function as heat generating sheets by passing current to generate heat, and can also be used as electrodes for touch screens, inorganic EL elements, organic EL elements, or electrodes for solar cells . Background technique [0002] Conventionally, windows described in JP-A-2009-137455, for example, have been proposed as windows for passenger vehicles that require visibility and electromagnetic wave shielding properties. The window is provided with a mesh layer. In the mesh layer, arc-shaped and conductive wires missing a part of the circle are repeatedly arranged in a lattic...
