preparation example Construction

[0123] The preparation method of the CNT dispersion liquid used in the present invention is not particularly limited, for example, it can be carried out in the following steps. Since the processing time at the time of dispersion can be shortened, it is preferable to prepare a dispersion containing CNT in a concentration range of 0.003 to 0.15% by mass in a dispersion medium, and then dilute it to a predetermined concentration. In the present invention, the mass ratio of the dispersion medium to the CNT (that is, the mass of the dispersion medium when the mass of the CNT is 1) is preferably 10 or less. If it is the above-mentioned preferable range, it will be easy to disperse uniformly, and on the other hand, there will be little influence of electroconductivity fall. The mass ratio of the dispersion medium to CNT is more preferably 0.5-9, still more preferably 1-6, particularly preferably 2-3.

[0124] As the dispersion means when preparing the CNT dispersion liquid, the use ...

[0186] Hereinafter, based on an Example, the manufacturing method of the electroconductive laminated body of this invention and the electroconductive laminated body of this invention is demonstrated concretely. However, the present invention is not limited to the following examples.

[0187]

[0188] (1) Light absorbance of the conductive laminate

[0189] About the electroconductive laminated body which sampled 5 cm x 10 cm, it measured using the ultraviolet-visible-infrared spectrophotometer UV-3150 by Shimadzu Corporation. Light was incident vertically from the side of the conductive laminate on which the conductive layer was formed, the total light transmittance and relative reflectance at 550 nm were measured, and the absorbance was calculated using the following formula to obtain the absorbance of the conductive laminate.

[0190] Absorbance (550nm) = 100 - total light transmittance (550nm) - relative reflectance (550nm).

(iii) The conductive layer (Y) contains carbon nanotubes (C) and a carbon nanotube dispersant (D). Provided is a conductive laminate which has excellent laser etching properties and low moisture dependence in addition to excellent transparency and conductivity.

Description

technical field [0001] The present invention relates to a conductive laminate, a method for manufacturing the conductive laminate, a touch panel, and a touch switch. More specifically, it is related with the manufacturing method of the electroconductive laminated body excellent in transparent electroconductivity, and an electroconductive laminated body. Background technique [0002] The conductive laminate is widely used in electronic display devices such as flat panel displays and touch panels. The conductive material used in the conductive laminate is represented by tin-doped indium oxide (hereinafter referred to as ITO), and the demand and usage of ITO continue to increase. However, since indium is a rare metal, a new conductive material that can replace indium is required. Alternatively, there is a demand for a new type of conductive material that can compensate for the specific shortcomings of conductive laminates using ITO (such as easy bending, difficulty in cost re...
