Plastic product containing luminescent material and method for determining authenticity of same

Abstract

Disclosed is a plastic product for which authenticity can be determined comprising: a base material made of a plastic material; and a light emitting material which is included in the base material and emits emission light including a second wavelength with respect to incident light including a first wavelength, wherein the determination of authenticity is performed by detecting the emission light after irradiating the incident light. According to the present invention, the authenticity of the plastic product can easily be determined by a simple method of detecting an emission spectrum emitted from the plastic product.

Description

However, the number of cases of counterfeiting of plastic products made of unapproved materials has recently increased, which has become a problem

Plastic products have the following problems: After molding or processing, or final productization, it is difficult to determine whether they are genuine products made of approved materials, and when a part of the overall volume is made of an inexpensive substitute material, it is difficult to distinguish its authenticity. in fact impossible

For example, if it is faked to observe an approximate image, it may be difficult for consumers to distinguish the authenticity only through visual observation.

[0008] In addition, due to the fact that it is easy to confirm with the naked eye that a security element is applied to a specific position of a product, it may be relatively easy to carry out counterfeiting

[0009] In addition, such technology can basically only affect the visual appearance of plastic products and has limitations in the scope of application.
