Embodiment 1

[0066] 6.7 parts by weight of phenoxy resin (manufactured by Mitsubishi Chemical Corporation, trade name "JER1256", bisphenol A type phenoxy resin, weight average molecular weight: 50000), 4.4 parts by weight of hexamethylene diisocyanate polyisocyanate compound ( Isocyanurate type, NCO%: 23.1% by weight) and butyl carbitol were mixed to prepare a varnish.

[0067] To the varnish (solid content: 11.1 parts by weight), add 100 parts by weight of flaky silver-coated copper powder (average particle size: 8 μm to 10 μm, silver coating amount: 15% by weight, aspect ratio: 45), 1 part by weight of Triethanolamine, 1 part by weight of phosphorus-containing organic titanate (bis(dictylpyrophosphate)oxyacetate titanate (bis(dioctylpyrophosphate)oxyacetate Titanate)), and defoamer, prepared Get conductive paste.

Embodiment 2

[0069] The addition amount of triethanolamine is 1.5 parts by weight, and the addition amount of phosphorus-containing organic titanate (bis(dioctylpyrophosphate)oxyacetate titanate) is Except 1.5 weight part, it carried out similarly to Example 1, and produced the electrically conductive paste.

Embodiment 3

[0071] Set the addition amount of triethanolamine to 2 parts by weight, the addition of phosphorus-containing organic titanate (bis(dioctylpyrophosphate)oxyacetate titanate) Except that the quantity was 2 parts by weight, it carried out similarly to Example 1, and produced the electrically conductive paste.

Abstract

Provided is a solderable conductive paste, which cures at low temperatures, has excellent adhesion with ITO layers, and is inexpensive. This conductive paste comprises: a flaky silver coated copper powder; a phenoxy resin; a hexamethylene diisocyanate-based polyisocyanate compound and / or a block isocyanate compound; a phosphorus-containing organic titanate; and an alkanolamine. The content ratio of the flaky silver coated copper powder is 88 parts by weight to 92 parts by weight, with respect to 100 parts by weight of the total amount of the flaky silver coated copper powder, the phenoxy resin, the hexamethylene diisocyanate-based polyisocyanate compound and the block isocyanate compound.

Description

【Technical field】 [0001] The invention relates to a conductive paste. 【Background technique】 [0002] In recent years, mobile devices such as mobile phones use transparent conductive films as electrodes of touch sensors. The commonly used transparent conductive film is a transparent conductive film obtained by forming a transparent conductive layer made of a metal oxide such as ITO (indium tin oxide) on a transparent resin film (substrate) such as a PET film. The transparent conductive layer made of ITO can be obtained by forming an ITO coating layer on a substrate by vapor deposition or sputtering, and then forming a circuit by etching the coating layer. [0003] Generally, various components are mounted on the transparent conductive layer. Since components cannot be mounted with solder on a transparent conductive layer made of ITO, a method of fixing components with a conductive adhesive is used. Alternatively, the following method may be used: arrange a circuit formed ...
