Abstract

A composition for forming a metallic luster film, includes: a thiophene polymer, in which a total content of an Fe atom, a Cu atom, an Mn atom, a Cr atom, and a Ce atom in the composition for forming a metallic luster film is 1500 ppm or less with respect to the thiophene polymer.

Claims (30)

1. A composition for forming a metallic luster film, the composition comprising:

an alkoxythiophene polymer,

wherein a total content of an Fe atom, a Cu atom, an Mn atom, a Cr atom, and a Ce atom in the composition for forming a metallic luster film is 15 ppm or more to 1500 ppm or less with respect to the alkoxythiophene polymer.

2. The composition for forming a metallic luster film according to claim 1 ,

wherein the total content of the Fe atom, the Cu atom, the Mn atom, the Cr atom, and the Ce atom in the composition for forming a metallic luster film is 15 ppm or more to 500 ppm or less with respect to the alkoxythiophene polymer.

3. The composition for forming a metallic luster film according to claim 2 ,

wherein the total content of the Fe atom, the Cu atom, the Mn atom, the Cr atom, and the Ce atom in the composition for forming a metallic luster film is 15 ppm or more to 100 ppm or less with respect to the alkoxythiophene polymer.

4. The composition for forming a metallic luster film according to claim 1 ,

wherein an alkoxy group of the alkoxythiophene has 1 or more and 6 or less carbon atoms.

5. The composition for forming a metallic luster film according to claim 1 ,

wherein the composition for forming a metallic luster film is a liquid composition.

6. The composition for forming a metallic luster film according to claim 1 ,

wherein the composition for forming a metallic luster film is a solid composition.

7. The composition for forming a metallic luster film according to claim 1 ,

wherein an alkoxy group of the alkoxythiophene has 1 or 2 carbon atoms.

8. A metallic luster film, comprising:

an alkoxythiophene polymer, wherein a total content of an Fe atom, a Cu atom, an Mn atom, a Cr atom, and a Ce atom in the metallic luster film is 15 ppm or more to 1500 ppm or less with respect to the alkoxythiophene polymer.

9. The metallic luster film according to claim 8 ,

wherein the total content of the Fe atom, the Cu atom, the Mn atom, the Cr atom, and the Ce atom in the metallic luster film is 15 ppm or more to 500 ppm or less with respect to the alkoxythiophene polymer.

10. The metallic luster film according to claim 9 ,

wherein the total content of the Fe atom, the Cu atom, the Mn atom, the Cr atom, and the Ce atom in the metallic luster film is 15 ppm or more to 100 ppm or less with respect to the alkoxythiophene polymer.

11. The metallic luster film according to claim 8 ,

wherein each of an alkoxy group of the alkoxythiophene has 1 or more and 6 or less carbon atoms.

12. The metallic luster film according to claim 8 ,

wherein an alkoxy group of the alkoxythiophene has 1 or 2 carbon atoms.

13. An article comprising:

a metallic luster film that comprises an alkoxythiophene polymer,
