Abstract

See full text

A method for producing a binder resin by a reaction of a cellulose derivative, a polyvinyl acetal, and a bonding agent that has in the molecule at least two functional groups that can react to hydroxyl groups in the polyvinyl acetal and the cellulose derivative. In the production method, the content of the bonding agent is at least double the molar quantity of whichever has the greater number of moles between the polyvinyl acetal and the cellulose derivative. The produced binder resin is favorable in a coating paste such as a conductive paste, and causes an improvement in film quality such as the smoothness and denseness of a coating film formed by the paste.
