    Abstract: [Problem]
    The performance required for conductive liquid compositions includes the ability for a single type of conductive liquid composition to be used in common for plastic substrates including flexible sheets and the like and conventional glass, and a conductive function that exhibits adequate performance for a given purpose even at a low film thickness, as well as a high leveling property (surface smoothness) to exhibit a uniform conductive function without fine irregularities even as a thin coated film, and the ability to adequately withstand rinsing with MEK and the like used for removal of trace contamination.
    [Solution Means]
    A conductive liquid composition comprising:
    (A) containing, for a binder resin, from 5 to 25 mass% of a hydroxyl-containing resin with a hydroxyl value from 3 to 100 and a weight-average molecular weight from 4000 to 20000,
    (B) containing, for a solvent, one or two more types of solvents with boiling points of not less than 170°C selected from among isophorone, dibasic acid esters, 3-methoxy-3-methylbutanol, 3-methoxy-3-methylbutyl acetate, ethyleneglycol monobutyl ether acetate, coal tar naphtha with a boiling point of more than 170°C, diethyleneglycol monoethyl ether, diethyleneglycol monoethyl ether acetate, diethyleneglycol monobutyl ether, diethyleneglycol monobutyl ether acetate, triethyleneglycol monobutyl ether, triethyleneglycol monobutyl ether acetate, polyethyleneglycol dimethyl ether, tetraethyleneglycol dimethyl ether and polyethyleneglycol monomethyl ether, at not less than 70 mass% of the total solvent,
    (C) containing, for a curing agent, from 1.5 to 10.0 mass% of polyisocyanate,
    (D) containing, for a curing accelerator, from 0.005 to 0.1 mass% of an organometallic compound,
    (E) containing, for an adhesion reinforcing agent, from 0.2 to 2.5 mass% of a coupling agent,
    (F) containing, for conducting materials:
    (f1) from 2.0 to 10.0 mass% of graphite,
    (f2) from 5.0 to 15.0 mass% of conductive carbon black, and
    (f3) from 20.0 to 50.0 mass% of silica particles with a mean particle size from 1.0 to 7.0 µm and surface-coated with silver, and

    (G) having a surface resistivity from 1 to 1000 Ω/sq. when the thickness of the cured film of the conductive liquid composition is 8 µm.
