Abstract

An ornament includes a base material; and a silver particle layer containing silver particles and disposed on the base material, wherein the silver particle layer has surface resistivity of 10 4 Ω/□ or more, and the silver particles are stacked in the silver particle layer in a thickness direction of the silver particle layer.

Claims (24)

1 . An ornament comprising:

a base material; and

a silver particle layer containing silver particles and disposed on the base material,

wherein the silver particle layer has surface resistivity of 10 4 Ω/□ or more,

the silver particles are stacked in the silver particle layer in a thickness direction of the silver particle layer, and

the ornament is silver-colored.

2 . The ornament according to claim 1 , wherein tin is present between the base material and the silver particles.

3 . The ornament according to claim 1 , wherein the silver particles account for 95% or less of the silver particle layer.

4 . The ornament according to claim 1 , wherein the silver particles contain precipitated silver particles.

5 . The ornament according to claim 1 , wherein the silver particle layer has a sea-island structure dotted with island-shaped silver particles.

6 . The ornament according to claim 1 , wherein an undercoat layer is disposed between the base material and the silver particle layer.

7 . The ornament according to claim 1 , wherein a topcoat layer is disposed on the silver particle layer.

8 . An ornament comprising:

a base material; and

a silver particle layer containing silver particles and disposed on the base material,

wherein the silver particle layer has surface resistivity of 10 7 Ω/□ or more,

the silver particles are stacked in the silver particle layer in a thickness direction of the silver particle layer, and

the silver particle layer has a thickness of from 30 nm to 200 nm.

9 . The ornament according to claim 8 , wherein tin is present between the base material and the silver particles.

10 . The ornament according to claim 8 , wherein the silver particles account for 95% or less of the silver particle layer.

11 . The ornament according to claim 8 , wherein the silver particles contain precipitated silver particles.

12 . The ornament according to claim 8 , wherein the silver particle layer has a sea-island structure dotted with island-shaped silver particles.

13 . The ornament according to claim 8 , wherein an undercoat layer is disposed between the base material and the silver particle layer.

14 . The ornament according to claim 8 , wherein a topcoat layer is disposed on the silver particle layer.
