Abstract
Description
Compound metals, compounds
[0001] The present invention relates to a compound-bearing metal and a compound.
[0002] Metal materials are used in a variety of applications, including touch panels, solar cells, and electroluminescence (EL) elements. For example, they are used in the above applications as conductive materials, such as metal films and conductive wiring (thin wire-like wiring that exhibits conductivity), and the environments in which they are used and the performance requirements are becoming more diverse. Metals may corrode depending on the environment in which they are used, and may no longer be able to perform their desired functions. For example, corrosion of metals used as conductive materials can cause defects such as increased resistance, discoloration, and migration, so it is necessary to impart corrosion-inhibiting properties to metal materials.
[0003] As an example of such conductive wiring, Patent Document 1 describes a transparent electrode including a conductive layer and an intermediate layer provided adjacent to the conductive layer, wherein the transparent electrode has a light transmittance of 50% or more at a wavelength of 550 nm and a sheet resistance of 20 Ω / □ or less, the intermediate layer contains an organic compound having both a covalent bonding moiety capable of covalently bonding with silver and a coordinate bonding moiety capable of coordinate bonding with silver within the molecule, and the conductive layer contains silver as a main component.

The compound-attached metal of the present invention comprises a metal and, attached to the metal, at least one specific compound selected from the group consisting of a compound represented by formula (1A) described below and a compound represented by formula (1B) described below.
[0018] Although the reason why the compound-attached metal having the above-described structure can solve the problems of the present invention is not entirely clear, the inventors speculate as follows. The following speculation does not limit the mechanism by which the effect is obtained. In other words, even if the effect is obtained by a mechanism other than the one described below, it is still within the scope of the present invention. The specific compound has a predetermined specific functional group that interacts with the metal. Furthermore, the specific compound has a predetermined triazine skeleton and one or more aromatic rings, and has numerous hydrogen bonding sites and π-π interaction sites. Due to the above structure, the specific compound easily adheres to the metal surface and is capable of stacking with other specific compounds. As a result, it is speculated that a dense corrosion-preventing film of the specific compound is formed on the metal, thereby inhibiting metal corrosion. Hereinafter, the fact that corrosion of the compound-attached metal is better inhibited will also be simply referred to as "the effect of the present invention being better."

[0128] <Copper Oxidation Test> Each specific compound or comparative compound was dissolved in a mixed solvent of ethylene glycol monoethyl ether / water = 50 / 50 (mass ratio) to prepare 30 ml of a solution at a concentration of 0.5 wt %. 2 SO 4 A 3 cm square copper foil, which had been immersed in an aqueous solution (liquid temperature: 30° C.) for 10 minutes to remove the oxide film from the surface, was prepared and immersed in the solution at room temperature for 60 seconds. After immersion, the copper foil was immersed in 30 ml of pure water for washing and then dried at 70° C. for 1 minute to obtain a compound-coated copper foil.
[0129] The obtained copper foil with the compound was placed in a thermostatic chamber at 60°C and 90% RH and heated. The foil was checked every half day for 5 days from the start of heating, and the number of days until the copper foil turned black was measured. The longer the time until the foil turned black, the more inhibited corrosion is, which is preferable.
