Problems solved by technology

However, if a large amount of flaky silver powder is mixed, the thixotropy of the conductive paste will become too high, and the printing suitability in the gravure printing method will be reduced. Therefore, it is not suitable for forming fine particles such as conductive mesh patterns. The purpose of the line
On the other hand, in order to form fine wires, there is a method of making the particles of silver powder finer and reducing the amount of compounding, but the contact between the conductive powders in the conductive paste is difficult to obtain, and the conductivity to the extent of electromagnetic wave shielding cannot be obtained.

Embodiment 1～6 and comparative example 1～2

[0064]Each component was mixed according to the compounding ratio shown in Table 1, and it kneaded with the 3-roll kneader, and obtained the conductive paste. In addition, after kneading, the viscosity was adjusted to 500 dPa·s with an organic solvent, and then evaluated.

[0065] [Table 1]

[0066]

[0067] The conductivity, printability, drying resistance, and tack value of the various conductive pastes thus obtained were evaluated. The evaluation method is as follows.

[0068] (1) Evaluation of electrical conductivity

[0069] The obtained various conductive paste patterns were printed on a glass substrate to form a 0.5 cm×10 cm pattern, and heat treatment was performed at 120° C. for 30 minutes to form a 0.5 cm×10 cm conductive pattern. The sheet resistance value of the conductive pattern was measured by a four-probe method using a milliohm high tester, and the resistivity value was calculated from the measured value of the thin layer and the film thickness to eval...

Abstract

The invention provides a conductive paste and light permeability conductive film and method of manufacturing the same. The present invention provides a polymer conductive paste which has both electromagnetic wave shielding (conductive) performance and printability, can easily and inexpensively manufacture electromagnetic wave shielding film. The inventive conductive paste for gravure printing is characterized in that the conductive paste contains organic binders, conductive powders, coloring agents and organic solvents, wherein the organic solvents have high boiling point solvent whose boiling point is in the range of 240 - 330 DEG C at 760mmHg.

Description

technical field [0001] The present invention relates to an electroconductive paste, a translucent electroconductive film, and a method for producing the same. More specifically, it relates to a conductive paste suitable for producing a light-transmitting conductive film used as a shield by CRT (cathode ray tube), PDP (plasma display panel), EL (electroluminescence) Electromagnetic wave shielding filters for displays are useful for electromagnetic waves generated in front of displays such as panels. Background technique [0002] In the past, when it comes to monitors, CRT monitors were typically used, but recently, instead, FPDs (Flat Panel Displays) have been popularized as thin TVs and the like. Among FPDs, LCD (Liquid Crystal Display) and PDP are the first to be popularized. In addition to these, FED (Field Emission Display), which is attracting attention as SED (Surface-conduction Electron-emitter Display), is expected to further develop in the future. universal.
