Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a phosphorescent paper, and more particularly to an improved phosphorescent paper that can be used for more purposes.

[0002]

[Prior art]

 Luminescent paper is the paper itself or a special material applied to the surface of the paper that accumulates light energy such as sunlight and electric light, and emits light in the absence of light. A so-called luminescent agent as a luminescent material for that purpose is conventionally known, but the luminescent agent is a special substance and its particles are extremely coarse, and it does not dissolve in water or a general solvent at all. It was difficult to make a phosphorescent paper that can be uniformly coated on the surface to withstand general use, but a common phosphorescent paper was developed by the same inventor, and a patent application was filed as Japanese Patent Application No. 6-42997. Has been done.

[Problems to be solved by the device]

 However, in order to make the luminous effect of the luminous paper sufficient, the luminous agent layer is made thicker by double coating, so the overall thickness of the luminous agent becomes thicker, and when the luminous sheet is bent, the luminous agent layer has cracks. It had drawbacks such as inclusions and peeling, and its use was limited. In addition, since the phosphorescent agent layer substantially forms the surface layer, there was a concern that the phosphorescent agent layer would not have any adverse effects on the human body.

The present invention can be applied to a wide range of applications without cracking of the phosphorescent agent layer even when it is used for applications requiring extreme folding such as origami or wrapping paper, and has no adverse effect on the human body at all. The purpose is to provide phosphorescent paper.

[0004]

[Means for Solving the Problems]

Phosphorescent paper of the present invention comprises AC coat layer on one side of the pure white roll paper of ^40g / ^{m 2 ~70g} / m 2 as a base, a two-layer luminescent agent layer, a plastic sheet layer of 5~20μ thickness on the order , Provided with an anti-curl coating layer on the opposite surface. Polyester is most preferred as the plastic, but is not necessarily limited thereto. The phosphorescent paper of the present invention is made to be embossed from the surface of the plastic sheet layer, so that the phosphorescent paper has more flexibility and can withstand extreme bending. The embossing may be to emboss the entire thickness of the phosphorescent paper or may be to emboss the surface on the plastic sheet side. The AC coat layer is preferably made of nitrified cotton and thinner, the phosphorescent agent layer is made of luminous pigment, urethane clear, and thinner, and the curl prevention coat layer is preferably made of Rastergen FD and warm water. Parts, 3 parts by weight of clear nitrified cotton, and 2 parts by weight of thinner, the phosphorescent agent comprises 5 parts by weight of phosphorescent pigment, 5 parts by weight of urethane clear, and 2 parts by weight of thinner, and the curl-preventing coating agent comprises 1 part by weight of Rustergen FD and Suitably it comprises 50 parts by weight of warm water.

The AC coating agent has an adhesion amount of 12 gwet / m ² , the phosphorescent agent has an adhesion amount of 60 wetg / m ² (25.5 g / m ² after drying), and the curl prevention coating agent has an adhesion amount of about ²⁰ gwet / m ^2. It is preferable that the above configuration is adopted.

[0006]

[Action]

 An extremely thin base paper and a plastic sheet laminated on the outside of the phosphorescent agent layer protect the phosphorescent agent layer against bending and prevent cracking and peeling, and the plastic sheet adversely affects the human body due to the phosphorescent agent layer. Completely prevent. Furthermore, by embossing from the outside of the plastic sheet, it is possible to make it more resistant to bending.

【Example】

Using a 150-mesh (line) mesh roll gravure coater, one side of 40 g / m ² pure white roll paper 1 with a width of 1,090 mm was coated with an AC coating agent of the following composition, and then AC coated. Layer 2 was formed. Composition of AC Coating Agent 3 parts by weight of nitrified cotton white 3 parts by weight of clear 3 parts by weight of thinner (Sakueti: Toluol = 5: 5) 2 parts by weight The AC coating agent layer 2 was coated so as to have a weight of 12 gwet / m ² .

The coated pure white roll paper 1 was dried by a conventional method. A pure white roll paper 1 that had been dried was coated with a luminescent agent having the following composition on the AC coat layer 2 using a 40 mesh (line) mesh roll gravure coater to form a luminescent agent layer 3.

Composition of Luminescent Agent Luminescent Pigment 5 parts by weight Urethane Clear 5 parts by weight Thinner (Sequet: Toluol = 5: 5) 2 parts by weight For the gravure coater, the phosphorescent agent is sufficiently stirred and the phosphorescent agent is as uniform as possible. For the purpose of coating, a roller was added which was brought into contact with the surface of the mesh roll and rotated together with the mesh roll. The coated pure white roll paper 1 was dried in the same manner as above, changed to an 85 mesh (line) roll and further coated with a phosphorescent agent in the same manner as above, and dried. Luminescent agent is about 40gwet / ^{m 2} with a coating of the first round, about 20gwet / ^{m 2} by the second co computing total in 60gwet / ^{m 2} (attached amount of the phosphorescent pigment after drying of about 25.5 g / m ² ) was coated. A dry laminate composition having the following composition that functions as the adhesive layer 4 is applied to the dried product using a gravure coater with a 40-mesh (mesh) mesh roll so that the applied amount will be 45 g / m ² and a thickness of 9 μm. The polyester sheet 5 was laminated thereon, and heat-bonded onto the phosphorescent agent layer 3 with a heat roller and dried. Dry laminating composition Urethane clear 5 parts by weight Curing agent 1 part by weight Thinner (Sakueti) 2 parts by weight Then, on the back surface of the pure white roll paper 1, a curl-preventing coating agent 6 having the following composition is similarly used using a gravure coater. And coated so that the adhesion amount was 20 gwet / m ² .

Composition of anti-curl coating agent Rastergen FD 1 part by weight Hot water 50 parts by weight Pure white roll paper 1 coated with anti-curl coating agent is dried in the same manner as above. Furthermore, a satin embossing 7 was formed from the surface of the laminated polyester sheet by embossing. The satin embossing was formed on the entire thickness of the phosphorescent paper. The phosphorescent paper prepared in this way is a pure white roll paper 1 of 40 g / m ² , an AC coat layer 2 of 12 gwet / m ² , and a phosphorescent agent layer 3 of 60 gwet / m ² (25.5 g / m ² after drying). The anti-curl coating layer 6 has a composition of ²⁰ gwet / m ² , and even if it is used as origami or wrapping paper, for example, the phosphorescent agent layer does not crack or peel off when folded and is sufficient. It was durable to use.

[0008]

[Effect of device]

 In the phosphorescent paper of the present invention, a very thin pure white paper is used as a base, and a plastic sheet is laminated on the outer side of the phosphorescent agent layer, so that the phosphorescent agent layer can be easily peeled off even when the application requires extreme bending. It does not crack and can completely prevent any adverse effects on the human body. Particularly effective softness is obtained by embossing on the polyester sheet.
