However, when the viewing angle changes, the deposition sheet with a deposition surface such as a mirror surface is dazzling and difficult to see at the angle where the reflected light from the light source directly enters the eyes, while most of the reflected light from the light source is from the eyes. At a deviating angle, no shine is felt, and the printed image on the surface becomes dark and difficult to see. Therefore, there is a problem that it is difficult to obtain a certain design and high-quality feeling.
By the way, for example, there is a vapor deposition sheet that has light scattering reflectivity that reflects light in a random direction by forming irregularities on the surface of the vapor deposition surface. It is used for purposes. And if it can be printed on the surface while maintaining light scattering reflectivity, the design by printing and the design by vapor deposition will be combined, and its application is expected to expand dramatically. It becomes.
However, since the conventional vapor deposition sheet having light scattering reflectivity has low surface activity, it has not been possible to perform printing in which printing ink is highly adhered to the surface while maintaining light scattering reflectivity.
Then, the present inventors make it a subject to propose the printable light-scattering reflection deposition sheet | seat which enables the printing in which printing ink adhered to the surface highly, maintaining a light-scattering reflectivity.

  The present invention has been proposed in view of the above, and is characterized in that a deposited film is laminated on one side of a substrate, an anchor layer is formed on the surface of the deposited film, and the deposited film has light scattering reflectivity. The present invention relates to a printable light scattering reflection deposition sheet.

  Further, the present invention is the printable light scattering reflection deposition sheet, wherein the anchor layer is any one of a vinyl acetate resin system, a urethane resin system, an epoxy resin system, an acrylate resin system, and a rubber system. A printable light-scattering / reflecting vapor-deposited sheet is also proposed, characterized in that it is 90/100 or more in a tape test in the later JIS standard.

  Furthermore, the present invention is the above printable light scattering reflection deposition sheet, wherein the deposition film is any one of PET, PEN, PVC and PO, and the deposited metal type is aluminum, silver, gold, zinc sulfide. Also proposed is a printable light-scattering / reflecting vapor-deposited sheet characterized by being any of titanium oxide.

  The present invention also proposes the printable light-scattering / reflecting vapor deposition sheet described above, wherein the printable light-scattering / reflection-deposited sheet is used as a card, a leaf document, or a catalog after printing on the surface.

  The printable light-scattering / reflective deposition sheet of the present invention can be printed on the surface while maintaining light-scattering / reflecting properties, and can be widely used for cards, leaf documents, catalogs, etc. it can.

  In particular, since it is light scattering and reflective, it has high visibility, and it is possible to relatively improve visibility by further printing.

  The substrate used in the present invention may be paper or film, or may have various types of printing applied on the surface thereof, and the configuration is not particularly limited. For example, it may be in the form of a roll or cut into a predetermined size in advance.

  Moreover, the vapor deposition film used in the present invention has light scattering reflectivity, and the film material is any one of PET, PEN, PVC, POs, and the vapor deposition metal type is aluminum, silver, gold, zinc sulfide. , Any of titanium oxide, and the deposition thickness is not particularly limited, but is preferably 200 to 800 mm. Such a deposited film is already commercially available, and a commercially available product (for example, “SR film” manufactured by Oike Kogyo Co., Ltd.) may be used.

Furthermore, the anchor layer used in the present invention is selected from those having excellent adhesion to each of the deposited film located on the lower side of the anchor layer and the printed layer located on the upper side of the anchor layer. Any of urethane resin, epoxy resin, acrylate resin, and rubber can be appropriately selected.
“Excellent adhesion” means that 90/100 or more (more preferably 100/100) that can withstand practical use in a tape test (using Nichiban's cello tape (registered trademark)) in JIS standards is good. did. If it is less than 90/100 empirically, peeling or the like may occur. In addition, the tape test in said JIS standard refers to the adhesion test in ink, a paint, etc .; what is called the cellophane tape peeling test of old JIS K 5400. Cuts are made in a grid pattern, and the cellophane tape is applied and then peeled off, and the number of peeled pieces out of 100 pieces is checked.

  The printing performed on the anchor layer may be performed using an ink that is in close contact with the selected anchor layer, and the adhesiveness may be determined as long as a good result can be obtained by the above-described adhesion test (tape test). For example, as shown in the examples described later, it has been confirmed that ultraviolet curable ink (“UV161” manufactured by T & K TOKA) has excellent adhesion.

  The printable light-scattering / reflecting vapor deposition sheet of the present invention thus configured has light-scattering reflectivity and can be printed on its surface, so it can be used as various cards, leaf documents and catalogs. Can do. And it is excellent in visibility and can be used suitably compared with a conventional product.

[Example 1]
On a coated paper having a basis weight of 200 g / m 2, a silver-deposited PET film (“SR film” manufactured by Oike Kogyo Co., Ltd.) having a silver deposition thickness of 350 mm with improved light scattering reflectivity was laminated with the film surface facing up. Polyvinyl chloride resin-based anchor agent (PET134 Anchor T manufactured by Toyo Ink Manufacturing Co., Ltd.) is uniformly coated with a thickness of 0.5 μm, and UV multicolor printing using ultraviolet curable ink (“UV161” manufactured by T & K TOKA) As a result of the evaluation, the evaluation of the tape test according to JIS standard showed that the printing ink had good adhesion to the substrate, and a printed sheet having light scattering reflectivity was obtained.
In addition, the method of the tape test in the JIS standard is to cut 10 pieces at 1 mm intervals vertically and horizontally with a cutter blade in accordance with the JIS standard, and paste Nichiban's cello tape (registered trademark) on it, Then, by peeling, it was judged by how many of 10 × 10 = 100 cocoons were peeled off. The results of this example were good at 100/100 (no peeling).

[Example 2]
The laminated product in production in Example 1 was coated with an acrylic ester resin-based anchor agent (“UV VP medium” manufactured by T & K TOKA) with a uniform thickness of 0.3 μm, and the same UV as in Example 1 As a result of multi-color printing, a tape test evaluation of JIS standard gave a 100/100 result, showing that the adhesion of the printing ink to the ground was good, and printing with light scattering reflectivity Possible vapor-deposited paper was obtained.

[Example 3]
The printed sheet obtained in Example 1 was cut into a card having a predetermined size to obtain a product.
When viewed from the surface, this card was excellent in visibility and high light scattering reflectivity.

Regarding the anchor layer, not only those described in the above-mentioned examples, but also urethane resin-based, epoxy resin-based, and rubber-based materials can be used as appropriate.
