Document Type and Number:
Japanese Patent JP6767089
Kind Code:
B2
Abstract:
The electro-conductive paste has fine-line printability of 50μm or less, outstanding adhesion to an ITO film in an electro-conductive pattern formed by a low-temperature process at a temperature not exceeding 150°C, and achieves environmental reliability and high durability. The electro-conductive paste contains at least: a thermoplastic resin (A) and a thermoplastic resin (B), a hardener (C), an electro-conductive powder (D) and an organic solvent (E). The weight ratio of thermoplastic resin (A) to thermoplastic resin (B) does not exceed 4.0:1, and thermoplastic resin (A) is a polyurethane resin or a polyester resin having a weight-average molecular weight of at least 10,000 and a glass transition temperature of -10 to 150°C. Thermoplastic resin (B) is a polyester polyol and/or polyether polyol, having a number average molecular weight of 500 to 6,000.
