Field of the Invention The present invention relates to a luminescent transfer printing material which gives a clear pattern pattern having a retroreflective effect and a light emitting effect by live light on a transfer material by a transfer adhesion operation, and a method for producing the same. .

[0002]

2. Description of the Related Art It has been conventionally known to form a product that emits light at night by using a print product containing a light-saving material or a transfer material product containing the light-saving material.

Further, conventionally, a colored synthetic resin layer and a synthetic resin adhesive layer are provided by various printing means on a mount on which glass beads are temporarily adhered to obtain a retroreflective transfer printing material, and the retroreflective transfer printing is performed. It is known to perform retroprinting on various materials to be transferred by treatment such as heating and pressurizing the material to form a retroreflective product having a retroreflective pattern.

[0004]

[Problems to be Solved by the Invention] By the way, a product which is made to emit light at night by using a print product containing a light-saving material or a transfer material product containing the light-saving material is exposed to light from the outside when used at night. When the light is completely cut off after being exposed to light, the part equipped with the light storage material emits light, but when the light hits from the outside and becomes bright, the light absorbed in advance is gradually emitted, but the light is absorbed more than the light from the outside. Since the light emission from the material is much weaker, the light emission cannot be visually observed, and there is a drawback that the existence of a product that emits light cannot be known.

Further, a colored synthetic resin layer and a synthetic resin adhesive layer are provided by various printing means on a mount to which glass beads are temporarily adhered to obtain a retroreflective transfer printing material, and the retroreflective transfer printing material is heated. When a retroreflective product with a retroreflective pattern is formed by performing transfer printing on various materials to be transferred by applying pressure, etc., it is possible to see the reflected light when it is illuminated by light. However, there is a drawback that it is not possible to know the existence of a retroreflective product because it does not retroreflect unless it is exposed to light from the outside.

The present invention solves the above-mentioned problems, and a retroreflective pattern can be printed on a material to be transferred by a simple one-time transfer operation such as heating and pressurization. Design expression can be done by simple operation,
It is also excellent in color development, designability, retroreflectiveness, retroreflective designability, handleability, transfer processability, adhesiveness to transfer material, etc., and it is illuminated or illuminated by light in a dark night or in a dark place. In any case, it can show the presence of the transferred material regardless of whether it is transferred or not, and after transfer to the transferred material, the adhesiveness, washing resistance, abrasion resistance, heat resistance, light resistance, etc. It is intended to obtain a luminescent transfer printing material which is excellent in various fastness, easy to handle and easy to produce, and a method for producing the same.

As the glass beads 3, commercially available glass beads for retroreflection can be used.

The shape of the base sheet 4 is selected according to the processing means and application, such as a single sheet or a roll sheet.

The pattern layer 5 is formed by adhering to the glass beads 3 and forming a mixture of a light-saving material and a polymer resin, which is temporarily adhered or not adhered to the glass bead temporary adhesion layer 2, into a desired pattern shape.

As a material for the light-saving material, an expensive material having high brightness, long afterglow, and non-toxicity, which has been recently supplied,
Alternatively, inexpensive ones such as zinc sulfide are used depending on the application such as those not requiring flexibility and those not requiring hygienic safety.

As the polymer resin material, a polymer resin binder or the like which has been used to form a conventionally known retroreflective transfer printing material is used.

The colored pattern layer 6 is composed of a pigment and a polymer resin that adheres to the pattern layer 5 and does not adhere or adhere to the glass bead temporary adhesion layer 2 even if it is layered by protruding from the pattern layer 5. The mixture is formed into a desired shape or laminated.
