Problems solved by technology

The advantage of this technique is that it can form a conductor pattern without going through a complicated process, but when it is used to form a high-precision pattern with a small gap between electrode lines, migration is induced and long-term reliability cannot be obtained

Embodiment

[0068] The present invention is described in detail below by examples, however, the present invention is not limited to the following examples. In addition, the following "parts" all mean parts by weight unless otherwise specified.

[0069] (Synthesis example of organic binder)

[0070] In a flask equipped with a thermometer, a stirrer, a dropping funnel and a reflux cooler, add the solvent diethylene glycol monoethyl ether acetate, the catalyst azobisisobutyronitrile, and heat to 80°C under a nitrogen atmosphere. Within 2 hours, methacrylic acid and methyl methacrylate were added dropwise at a molar ratio of 0.4 mol:0.6 mol, and after stirring for 1 hour, the temperature was raised to 115° C. to inactivate it to obtain a resin solution.

[0071] After cooling the resin solution, use the catalyst tetrabutylammonium bromide to add 0.4 mol of butyl glycidyl ether to the carboxyl group of the obtained resin under the condition of 95-105°C for 30 hours. ,cool down.

Abstract

The invention provides a glass composition for an electric conductive paste capable of preventing the induction of electrode migration even if used for the highly fine electric conductor pattern, a photosensitive silver paste using the same capable of providing a highly fine electric conductor pattern excellent in long term reliability with low migration. The glass composition for a silver paste contains boron of 10 mass% or less in terms of B2O3 and silica as essential components. The following equation (I) or (II) relating to a compositional ratio in terms of oxides is approved to the glass composition for the silver paste and the photosensitive silver paste involving the glass composition: B2O3 mass% <=SiO2 mass% (I), B2O3 mass%+ZnO mass% <=SiO2mass% (II).

Description

technical field [0001] The invention relates to a glass composition for silver paste and a photosensitive silver paste using the glass composition, in particular to a glass composition for silver paste suitable as an electrode material and a glass composition using the glass composition. Photosensitive silver paste, in which the electrode material is obtained by firing a graphic coating film formed by screen printing or photolithography. Background technique [0002] Conventionally, electrodes on non-alkaline glass and other various glass substrates have been formed by vapor deposition in components such as plasma display panels, CCD sensors, and image sensors. However, this vapor deposition method deposits the electrode forming material in a vacuum container and deposits the metal film, which has the disadvantages of large equipment, high cost, troublesome parts in and out, and poor operability, such as time required for vacuum introduction. In addition, it is difficult to...
