Abstract

The present invention is a transparent conductor containing electrically conductive particles, a binder, and an ultraviolet absorber. The transparent conductor of the present invention is so arranged that the ultraviolet absorber in the transparent conductor absorbs ultraviolet light even during irradiation of the transparent conductor with ultraviolet light, and is thus able to suppress influence of ultraviolet light on the electrically conductive particles.

Claims

1. A transparent conductor comprising an electrically conductive particle, a binder, and an ultraviolet absorber.

2. The transparent conductor according to claim 1, comprising:

an electrically conductive layer containing the electrically conductive particle and the binder; and

an ultraviolet absorbing layer containing the ultraviolet absorber.

3. The transparent conductor according to claim 1, wherein the ultraviolet absorber has at least one derivative selected from the group consisting of a triazine ring, benzotriazole, benzophenone, benzoyl methane, and hydroxybenzoate, or an azo group in a molecule.

4. The transparent conductor according to claim 2, wherein the ultraviolet absorber has at least one derivative selected from the group consisting of a triazine ring, benzotriazole, benzophenone, benzoyl methane, and hydroxybenzoate, or an azo group in a molecule.

5. The transparent conductor according to claim 1, wherein the ultraviolet absorber has at least one selected from the group consisting of titanium oxide, zinc oxide, iron oxide, aluminum oxide, cerium oxide, zirconium oxide, mica, kaolin, and sericite.

6. The transparent conductor according to claim 2, wherein the ultraviolet absorber has at least one selected from the group consisting of titanium oxide, zinc oxide, iron oxide, aluminum oxide, cerium oxide, zirconium oxide, mica, kaolin, and sericite.

7. The transparent conductor according to claim 1, wherein the binder is an acrylic resin.

8. The transparent conductor according to claim 2, wherein the binder is an acrylic resin.

9. The transparent conductor according to claim 3 wherein the binder is an acrylic resin.

10. The transparent conductor according to claim 4, wherein the binder is an acrylic resin.

11. The transparent conductor according to claim 5, wherein the binder is an acrylic resin.

12. The transparent conductor according to claim 6, wherein the binder is an acrylic resin.

13. A transparent conductor comprising an electrically conductive particle and an ultraviolet absorbing binder.

14. The transparent conductor according to claim 13, comprising:

an electrically conductive layer containing the electrically conductive particle and a binder; and

an ultraviolet absorbing layer containing the ultraviolet absorbing binder.

15. The transparent conductor according to claim 13, wherein the ultraviolet absorbing binder has at least one derivative selected from the group consisting of a triazine ring, benzotriazole, benzophenone, benzoyl methane, and hydroxybenzoate, or an azo group in a molecule.

16. The transparent conductor according to claim 14, wherein the ultraviolet absorbing binder has at least one derivative selected from the group consisting of a triazine ring, benzotriazole, benzophenone, benzoyl methane, and hydroxybenzoate, or an azo group in a molecule.
