Embodiment 1

[0121] As the aqueous dispersion of a composite of poly(3,4-ethylenedioxythiophene) and polystyrenesulfonic acid, Baytron PH500 manufactured by H.C. Starck (hereinafter referred to as aqueous dispersion (A)) was used. The electrical conductivity of this complex was measured and found to be 0.79 S / cm. In water dispersion (A) 10.4 parts (convert by solid content), add polyester resin aqueous dispersion (manufactured by Nagase Chemtex company, Gabsen ES-210) 3.0 parts (convert by solid content), melamine series cross-linking agent (Sumitomo Chemical production, Sumitex ResinM-3) 1.0 parts (converted by solid content), 20 parts of N-methylformamide, a small amount of surfactant, a small amount of leveling agent, an appropriate amount of water and modified methanol, stirred for 1 hour, Then, it filtered using the 400-mesh SUS sieve, and obtained the coating agent.

Embodiment 2

[0124] Except that the amount of the aqueous dispersion (A) is changed to 10.7 parts (converted by solid content), and the amount of the polyester resin aqueous dispersion is changed to 9.0 parts (converted by solid content), the same operation as in Example 1 , to prepare the coating agent.

Embodiment 3

[0126] As the aqueous dispersion of a complex of poly(3,4-ethylenedioxythiophene) and polystyrenesulfonic acid, Baytron PH510 manufactured by H.C. Starck (hereinafter referred to as aqueous dispersion (B)) was used. The electrical conductivity of this complex was measured and found to be 0.67 S / cm. A coating agent was obtained in the same manner as in Example 1, except that this water dispersion was used and the amount of the melamine-based crosslinking agent was changed to 3.0 parts.

Abstract

A conductive resin composition which contains a composite of a poly(3,4-dialkoxythiophene) and a polyanion, wherein the composite has a conductivity of 0.30 S / cm or higher. This composition is suitable for use in producing a conductive film comprising a conductive layer made of the composition. The conductive film is suitable for use in a resistive-film switch.

Description

technical field [0001] The present invention relates to a conductive resin composition applicable to a resistive film switch, a conductive film formed using the conductive resin composition, and a resistive film switch using the conductive film. Background technique [0002] The most common example of a resistive film switch is a touch panel. [0003] The touch screen is used for displaying images of display devices such as liquid crystal displays, cathode ray picture tubes, and electroluminescence (EL) displays. The touch screen is a kind of two-dimensional information resistive film switch. The touch screen is designed so that, for example, when any position on the screen is pressed with a finger or the tip of a pen, etc., the gap between the pressed position (conduction part) and the position of an electrode (such as a silver electrode) formed on a predetermined position of the touch screen is used. The resistance value obtained from the distance can be used to calculat...
