Phosphor-containing identification substance and method for producing the same
First Claim
1. A phosphor-containing identification substance comprising:
- a substrate comprising a main polymer component; and
a phosphor-containing silicone thin layer,wherein a whole or part of a surface of the substrate is covered with the phosphor-containing silicone thin layer,the main polymer component of the substrate is silicone, and the substrate and the phosphor-containing silicone thin layer are in an inseparable state,the phosphor-containing silicone thin layer is present on the surface of the substrate,a silicone composition that forms the phosphor-containing silicone thin layer does not have self-curing performance, but is cured in contact with the substrate, andthe phosphor-containing silicone thin layer has identification properties in which the phosphor-containing silicone thin layer emits visible light when irradiated with ultraviolet rays or black light, and does not emit visible light when irradiated with visible rays.

Abstract
A phosphor-containing identification substance of the present invention includes a substrate and a phosphor-containing silicone thin layer. The whole or part of the surface of the substrate is covered with the phosphor-containing silicone thin layer. The phosphor has identification properties that the phosphor emits light when irradiated with ultraviolet rays or black light, and does not emit light when irradiated with visible rays. A method for producing the phosphor-containing identification substance of the present invention includes bringing a silicone composition for forming a phosphor-containing thin layer into contact with the substrate after or simultaneously with the molding of the substrate, followed by heating. This provides the phosphor-containing identification substance that can be applied to a silicone thin film, has excellent adhesive properties with the substrate, and maintains the inherent properties of the substrate without being impaired by marking, and the method for producing the same.
