Problems solved by technology

[0007] Regarding the retroreflector disclosed in Patent Document 2, once the retroreflective sheeting etc. attached to the case etc. is peeled off, the glass bead layer will be destroyed, so it cannot be reused.
However, if an organic solvent such as alcohol is used or heated during peeling, the adhesive force of the adhesive layer of the retroreflector will be weakened, and the peeling can be performed without damaging the glass bead layer and the reflective layer, and it may be reused.

no. 1 Embodiment approach

[0044] Such as figure 1 As shown, the retroreflective label sheet 1 of the first embodiment includes: a base material layer 10; The detection light is retroreflected in the same direction; the adhesive layer 30 is laminated on the other side of the base layer 10 and is bonded to the article; the easily destructible layer 40 is arranged on the surface of the retroreflective layer 20 at least a part; and background information 50 composed of patterns, characters, etc. formed by printing on the surface of the substrate layer 10 on the side of the adhesive layer 30 . In this embodiment, the background information 50 is configured so that it can be seen from the front side of the retroreflective label sheet 1 . That is, the retroreflective layer 20, the fragile layer 40, and the base layer 10 are transparent. In addition, the background information 50 may be provided on the surface of the base material layer 10 on the retroreflective layer 20 side. To make the retroreflective la...

no. 2 Embodiment approach

[0071] Such as figure 2 As shown, the retroreflective label sheet 1A of the second embodiment includes: a base layer 10; a retroreflective layer 20A, which is laminated on one surface of the base layer 10, is transparent, and when the detection light is incident from a predetermined direction The detection light can be retroreflected in the same direction; the adhesive layer 30 is laminated on the other side of the base material layer 10 and bonded to the article; a part on the surface; and background information 50 formed of a pattern or characters on the surface of the base material layer 10 on the side of the adhesive layer 30 .

[0072] The retroreflective layer 20 includes a photorefractor layer 21 covered with glass beads, a holding layer 22 for maintaining the photorefractor layer 21 in a state where its surface is exposed, and a layer laminated on the surface of the photorefractor layer 21. The reflective layer 23A is laminated on the surface on the side opposite to ...

no. 3 Embodiment approach

[0076] Such as image 3 As shown, the retroreflective label sheet 1B of the third embodiment includes: a base layer 10; a retroreflective layer 20, which is laminated on one surface of the base layer 10, is transparent, and when the detection light is incident from a predetermined direction The detection light can be retroreflected in the same direction; the adhesive layer 30 is laminated on the other side of the base layer 10 and is bonded to the article; the peeling damage layer 60 is formed on the base layer 10 and between the adhesive layers 30; the fragile layer 40, which is provided on a part of the surface of the retroreflective layer 20; form. The retroreflective layer 20 has the same structure as that of the first embodiment, and includes a photorefractor layer 21 covered with glass beads, a holding layer 22 that keeps the photorefractor layer 21 in a state where its surface is exposed, and The reflective layer 23 is laminated on the surface of the light refractor l...

Abstract

Provided is a retroreflector label sheet and an article to which a retroreflector label sheet is boded wherein a judgment can be made whether a label sheet has been re-stuck or not by observing the conditions on the surface, unsealing can be confirmed, and forgery and camouflage can be inspected. The retroreflector label sheet (1) consists of a base layer (10), a retroreflective layer (20) that is laminated on one surface of the base layer (10) and can retroreflect a detection light, that has entered from a fixed direction, in the same direction, an adhesive layer (30) laminated on the other surface of the base layer (10) and adhering to an article, an easy-to-destroy layer (40) provided at least partially on the front surface of the retroreflective layer (20), and background information (50) consisting of designs or characters formed on the front surface of the base layer (10) on the side of the adhesive layer (30) by printing.

Description

technical field [0001] The present invention relates to a retroreflective label sheet, such as an open type retroreflective label sheet in which glass beads (hereinafter collectively referred to as light refractors) are exposed, and articles fixedly pasted with the retroreflective label sheet. Background technique [0002] A retroreflector utilizes a reflection phenomenon in which light incident on glass beads as a reflector returns to the incident direction again, and is composed of a glass bead layer as a light refractor and a reflective layer provided therebelow. The retroreflector includes a closed type in which a colorless and transparent resin coating is formed on glass beads, and an open type in which the glass beads are exposed. [0003] Patent Document 1 discloses a technique of combining a retroreflector and a hologram to enhance anti-counterfeiting. The retroreflector is often used in traffic signs, armbands, work clothes, etc. by virtue of the following properti...
