Embodiment 1）

[0090] Use the following reagents to prepare a homogeneous aqueous dispersion: Baytron PH500 (H.C. Starck Co. Production) 100 parts (including 1.1 parts of the conductive polymer and 98.9 parts of ion-exchanged water. When the conductive polymer is 100 parts, the ion-exchanged water is 8991 parts), as a binder alkoxy 24 parts of silane oligomer MS-51 (produced by Mitsubishi Chemical Corporation) (2165 parts when the conductive polymer is 100 parts), N-methylformamide (NACALAI TESQUE company (NACALAI TESQUE company) ), reagent) 19 parts (1730 parts when the conductive polymer is 100 parts), ethanol (manufactured by NACALAI TESQUE, reagent) 514 parts (46727 parts when the conductive polymer is 100 parts), ion-exchanged water 48 parts (4364 parts for 100 parts of conductive polymer).

[0091] Next, the above-mentioned dispersion liquid was coated on an alkali-free glass plate, and heated in an oven at 130° C. for 30 minutes to form a film to obtain a test piece with an antistati...

Embodiment 2）

[0094] Instead of Baytron PH500 (manufactured by H.C. STARCK) in Example 1, Baytron PH1000 (manufactured by H.C. STARCK, D50 of 52 nm, containing 1.1 parts of the conductive polymer) was used to obtain a test piece similarly to Example 1.

Embodiment 3）

[0096] Instead of Baytron PH500 (manufactured by H.C. STARCK Company) in Example 1, Baytron P (manufactured by H.C. STARCK Company, D50 of 140 nm, containing 1.1 parts of the conductive polymer) was used to obtain a test piece similarly to Example 1.

Abstract

The invention provides a conductive coating composition and a laminate. The conductive coating composition can be used to form an anti-static membrane having advantages of conductivity, high transparence, good attachment to the base material, high rigidity and good chemical resistance. The conductive coating composition comprises the conductive polymer particle having particle diameter D50 under 200nm, adhesive composition ingredient containing the alkoxy silane oligomer. The conductive polymer particle has preferably the particle diameter under 60nm, more preferably 30nm. The conductive polymer particle preferably a composition of Poly (3,4-disubstituted thiophene) and polyanion. By using the conductive coating composition provided in the invention, the normal coating method can be used to coat the cloth base material in low temperature to form the anti-static membrane, and the technology from coating to film forming can be realized with low costs.

Description

technical field [0001] The present invention relates to a conductive paint composition capable of forming a conductive film, an antistatic film, and the like, and a laminate using the paint composition. Background technique [0002] If dust adheres to the surface of the optical film of a display such as a liquid crystal display due to static electricity, the clarity of the display will decrease. As a method of preventing this, a method of providing an antistatic film on the surface of an optical film is known. [0003] Conventionally, antimony-doped tin oxide (ATO), indium tin oxide (ITO) and other inorganic fine particles exhibiting conductivity have been used as conductive materials formulated for such antistatic films. Such inorganic fine particles have the advantage of being excellent in transparency and film strength. [0004] However, an antistatic film containing inorganic fine particles is usually formed by sputtering or vacuum deposition, and has disadvantages of ...
