Embodiment 1

[0057] 43 parts of an aqueous solution of PEDOT / PSS (non-volatile content 0.52% by weight), 46.3 parts of ion-exchanged water, 0.1 part of p-toluenesulfonic acid, and 0.6 part of triethylamine were added and mixed well. Then, 10 parts of an isopropanol solution of tetramethylolmethane-tris(1-aziridinylpropionate) (1.4% by weight of non-volatile matter) was mixed with the obtained aqueous solution to prepare a conductive composition 1 . Table 1 shows the types of raw materials of this composition 1 and their respective weight %. The value of component (D) is the total value of components derived from component (A) and component (C) and externally added components.

Embodiment 2～13、 comparative example 1～2

[0059] Conductive compositions 2 to 13 and comparative conductive compositions (i) to (□) were prepared in the same manner as in Example 1, except that the types of raw materials and weight % were changed as shown in Table 1.

Abstract

The invention provides a conductive composition for forming a conductive film with easily-adjusted conductivity-static resistance. The conductive composition comprises a polyfunctional aziridini derivative (A) comprising at least three aziridinyls of special structures, an aziridinyls open-loop catalyst (B), a Pi conjugated system conductive polymer (C) containing heteroatom and a solvent (D).

Description

technical field [0001] The present invention relates to a conductive composition, a conductive film, and a method for producing them, which use polyfunctional aziridine derivatives as main film-forming components. Background technique [0002] As a conductive composition, for example, a conductive composition in which a metal filler (copper powder, etc.) is dispersed in a synthetic resin vehicle such as an acrylic resin emulsion is known, but since a large amount of metal filler is required, the conductive film Transparency or adhesion to the substrate was insufficient. [0003] In addition, a conductive composition in which a conductive polymer such as poly(aniline) is dispersed in a synthetic resin vehicle is known (see Patent Documents 1 and 2), but from the viewpoint of compatibility, due to conductive polymerization The usage amount of the material is limited, so it is difficult to obtain a coating with high conductivity. In addition, in order to secure film propertie...
