本考案は装飾用、印刷用とくにラベルに適する金属光沢
紙に関する。[Detailed Description of the Invention] The present invention relates to metallic glossy paper suitable for decoration, printing, and especially labels.
従来この種の金属化紙は基紙に接着剤層を介してアルミ

ったが、最近は省資源の観点から上記アルミニウム箔（
厚さは通常７〜１５μ）をアルミニウム真空蒸着層（厚
さは概七〇、０２５〜０．１２５μ）に代替えしようと
いう試みが進行中である。Traditionally, this type of metallized paper was mainly aluminum foil paper, in which aluminum foil was bonded to a base paper via an adhesive layer, but recently, from the perspective of resource conservation, aluminum foil (
Efforts are underway to replace the aluminum vacuum deposited layer (typically 7-15 microns thick) with a vacuum-deposited layer of aluminum (approximately 70,025-0.125 microns thick).

アルミニウム自身の溶解によって無制限に浪費されると
いう悩みがあり、この点からも前記アルミニウム箔をこ
れよりも遥かに負担の軽いアルミニウム真空蒸着層に置
換えたいという願望が強い。Furthermore, for labels, there is a problem that the amount of alkali required when collecting and cleaning pins, which is mainly applied, is wasted indefinitely by melting the aluminum itself in addition to the original label removal. There is a strong desire to replace this with an aluminum vacuum-deposited layer, which is a much lighter burden.

は公知である。A coating layer mainly composed of fine powder such as clay and adhesive is provided on the base paper to cover the unevenness and porosity of the paper, and then a heat-resistant resin layer that accepts metal vapor and has good adhesion is applied to the coating layer. It is known that metallized paper with a metallic luster comparable to that of aluminum foil paper can be obtained by vacuum evaporating lacquer and finally applying a layer of colorless or colored lacquer as a metal protective layer.
但しこれを更にラベルを適するものとするには、上記樹

せるため、上記樹脂層は低温のアルカリ液浸透を遮断し
て極めて薄いアルミニウム真空蒸着層の白化ないしは腐
蝕を防止する必要もある。However, in order to make the label even more suitable, the resin layer needs to be easily penetrated by the high-temperature alkaline solution commonly used when collecting and cleaning pins. Since a glue dissolved in alkali, such as casein glue, is applied to the entire back side of the base paper and left to dry naturally, the resin layer blocks the penetration of low-temperature alkaline liquid and prevents whitening or corrosion of the extremely thin vacuum-deposited aluminum layer. There is also a need to do so.
このような微妙な機能を具備し、かつ高度の金属真空蒸

ではない。A metallized paper that has such delicate functions and has a resin layer interposed therebetween that has a high level of metal vacuum deposition function is not yet known.

上述べた要点のすべてを満足する金属化紙が得られるこ
とを発見し提案するものである。This invention has been commercialized in recent years, and it was proposed after discovering that by applying a UV-curable solvent-free acrylic resin paint, a metallized paper that satisfies all of the above-mentioned points can be obtained. It is something to do.

ル系樹脂層３および３′の存在にある。That is, the present invention is shown in the drawings in which coated layers 2 and 2' mainly composed of fine powder and adhesive are provided on both sides of a base paper 1, and a solvent-free type coated layer 2 is cured with ultraviolet rays on one coated layer 2. The gist of this paper is the structure of a metallic glossy paper formed by sequentially forming an acrylic resin layer 3, an aluminum vacuum-deposited layer 4, and a colorless residue cured by ultraviolet rays or a colored solvent-free acrylic resin layer 3'. The novelty of the invention lies in the presence of solvent-free acrylic resin layers 3 and 3' cured by ultraviolet light.

である。UV-curable solvent-free acrylic resin paint is a substantially solvent-free paint that is made by adding a UV polymerization initiator to a mixture of acrylic monomers, oligomers, or resins that have functional groups. The coating layer can be completely cured by UV irradiation for only 1 to 5 seconds.

ある。The above-mentioned paint is applied as a temporary protective layer for rust prevention to a steel plate before being worked, and after processing, it is washed off at the same time as degreasing with a high-temperature alkaline solution, so it is the most suitable for this invention. It is.

光沢紙を得た。As an example of the present invention, Ubicoat Clear manufactured by Nippon Paint, which is a type of the above-mentioned paint, was coated on one coated surface of double-sided coated printing paper (mainly consisting of fine powder such as clay and adhesive) using a reverse roll coater. - After coating to a thickness of about 4μ, immediately apply 617L/cm under the focused light of an 80W/cm high-pressure mercury lamp.
After forming a mirror-hardened resin layer by irradiating with ultraviolet light at a rate of 10 minutes, pre-drying and vacuum degassing are performed, and then vacuum evaporating aluminum at a vacuum level of 10"Hg to form a 0.1μ thick deposited layer. Finally, a colorless case or gold-dyed Ubicoat clear was applied again under the above conditions and cured to obtain metallic gloss paper.

剥離することを確認した。The metallic gloss paper according to the above embodiment of the present invention is labeled with appropriate printing, coated with casein glue dissolved in various alkalis on the entire back side, pasted on a glass plate, and air-dried to whiten the Kahe aluminum vacuum deposited layer. No corrosion was observed at all, and when this was immersed in a 4% strength soda solution heated to about 70°C, it was confirmed that the label was easily peeled off in about 10 minutes.
