Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of adhering and forming a diffusely reflective vapor deposited film on the surface of a member to be adhered.

Laminated processed paper has been put into practical use as a decoration or packaging material, in which a metal film such as aluminum is formed on one side of a transparent plastic film and then affixed to one side of a paper sheet.

In this case, the surface is beautiful, the printing effect is excellent, moisture-proof, waterproof,
Although it is airtight, the surface of the paper is mirrored,
The incident light is reflected only in a certain direction depending on the angle of incidence, and this reflected light may directly enter the customer's eyes.
It tends to be too flashy, and is easily scratched and scratched, making it unsuitable as a decorative paper.

This invention does not impair the barrier properties against gas, water vapor, and heat rays like the conventional packaging materials formed with metal vapor deposition films, and has a diffused reflection surface that has an unprecedented white and beautiful shine unique to this invention. The purpose is to eliminate the above-mentioned drawbacks, and its feature is that a resin mixed with extremely fine particles is coated on one side of the sheet or film material, making the surface extremely fine and rough. a first step of forming a resin film on the surface; and a second step of forming a metal vapor deposition layer on the ultrafine rough surface of the film material obtained in the first step using a metal vapor deposition means. and this second step, the surface of the metal vapor deposited film is made into a very finely rough surface corresponding to the above-mentioned assembled surface, and after forming a diffusely reflective metal vapor deposited surface, the metal vapor deposited film having the very fine rough surface is formed into a very finely rough surface corresponding to the assembled surface. To provide a method for forming a diffusely reflective vapor deposited film on the surface of a member to be adhered, which is characterized by comprising a third step of peeling off from an extremely fine rough surface and transferring and depositing it on one surface of the member to be adhered. It is something.

An embodiment of the present invention shown in the drawings will be described in detail below.

- In Figure 1, 1 is a transparent or opaque synthetic resin film made of polyolefins, polyester, etc., which has a fairly low critical surface tension and an extremely smooth surface to form a metal vapor deposited film on one surface. The water is wound around a supply drum 2, and is adapted to be taken up on a take-up drum 3.

4 is a resin coating roller whose surface is finished smoothly.

5 is a doctor tooth, 6 is a container containing a molten resin made by adding ultrafine particles such as pigment particles and a solvent to a soluble transparent plastic that has good affinity for the film, and 7 is the resin-coated roller. 4 is a pressure roller that presses the synthetic resin film 1; 8a to 8f are guide rollers; 9 is a drying device that dries the resin film applied to the film; 10 is a continuous vacuum evaporation system with two chambers each at the front and rear. Decompression chambers 11a to 11
d, and includes a vacuum deposition chamber 12 in the center, and a heater 3 whose heating temperature can be controlled from the outside in the deposition chamber.
Guide plates 15a and 15b are provided to guide the lupus 14 and the evaporated metal to the film surface.

The inside of the vacuum deposition chamber 12 is designed to maintain a degree of vacuum of, for example, about 10-4 tons, and the AI, Au, Ag, Cu, Sn, and Zn put into the rubbo 14 under the vacuum are
, simple metals such as Cr, Ni, Se, Ti, Ni-Cr,
Alloys such as Ni-Fe, Fe-Co, Au-Ag-Cu, Sj02, Ti02, ln02, Yama203, Fe20
Metal oxides such as No. 3 and other metal compounds such as AgBr and AgCI are heated by a heater 13 made of a heat-resistant nichrome wire to evaporate them. The evaporated metal is turned into extremely small particles containing atoms and molecules, and then travels straight through the vacuum evaporation chamber 12 along guide plates 15a and 15b. It collides with layer a and comes to rest, forming a metal vapor deposited film layer b on the resin film layer a having an extremely fine rough surface. The thickness of the metal vapor deposited film layer can be adjusted by controlling the film transport speed and the amount of metal vapor generated. During this time, the synthetic resin film is wound from the supply drum 2 onto the take-up drum 3 at a constant speed by the driving roller 6 and the pressure roller 17.

FIG. 2 is an enlarged cross-sectional view of the case where a metal vapor deposited film layer b is formed on one surface of the synthetic resin film 1 via a resin film layer a with an extremely fine rough surface using the first step described above. On one side, a resin film layer a and a metal vapor deposition film layer b overlap on it, and due to the extremely fine particles such as pigment particles mixed in the resin and the viscosity and flow characteristics of the resin, the surface of the resin film layer a has extremely fine particles. Small irregularities are formed, and extremely minute irregularities are formed only on the surface of the metal vapor deposited film layer b to follow these micro irregularities, so even in this state, the incident light on the surface of the metal vapor deposited film layer b is extremely small. Effectively reflects diffused light with a white, shining feel.

Next, although it is possible to commercialize a diffusely reflective vapor-deposited film using only the first step of applying the resin and the second step of forming the metal-plated film layer b, the resin film layer a has a rough surface on one side. The third step of peeling off the vapor-deposited film layer b from the resin layer a and adhering it to one surface of a member to be adhered, such as paper, from the synthetic resin film on which the metal vapor-deposited film layer b has been formed will be described.

FIG. 3 shows an apparatus for carrying out the above-mentioned process, in which the synthetic resin film on which the vapor-deposited film layer is wound around the take-up drum 3 is applied to a material to be adhered (such as paper, cloth, etc.) having a high critical surface tension.
Pressure and laminator cooling rollers 22 together with said members from the supply drum 21 wound with (glass, metal, etc.) 20
, 23 and separation rollers 24a, 24b, the synthetic resin film 1 is transferred to the supply drum 2 which was emptied in the previous process.
Two members to be adhered are wound around a take-up drum 25. A rotating force is applied to the supply and take-up drums 2 and 25 having the same drum diameter through a common drive source (not shown), and the synthetic resin film 1 and the adhered member 2 are transferred from the take-up drum 3 and the supply drum 21 to the supply and take-up drums 2 and 25 having the same drum diameter.
0 at a constant speed. In addition, in conjunction with this winding operation, the molten polyethylene film c is applied to one surface of the adhered member 20 by the extrusion method using, for example, an extruder 26, and the molten polyethylene film c is applied to the metal vapor deposited film layer b. The member 20 to be adhered is pressed and cooled by the laminator cooling rollers 22 and 23, thereby producing a so-called anchoring effect.

Therefore, when the synthetic resin film and the adhered member 20 are separated into the supply drum 2 and take-up drum 25 side after passing through the separation rollers 24a and 24b, the resin film layer a on the synthetic resin film is changed to the vapor-deposited metal film layer b. is peeled off from the surface of the resin film layer a by utilizing the difference in critical surface tension between the resin film layer a and the member to be adhered 20, adheres to the member to be adhered to 20 side, and is wound up on the take-up drum 25. , a resin film layer a from which the vapor-deposited film layer b has been peeled off, and a synthetic resin film 1
was taken by take-up drum 3. If the vapor-deposited film layer b is coated with an adhesion aid such as tetrabutyl titanate, strong adhesion can be achieved in combination with the molten polyethylene film c. FIG. 4 shows the adhered member 20 that has undergone this third step.
In this enlarged sectional view, a metal vapor deposited film layer b is attached on the adhered member via a polyethylene melt film layer c, but the metal vapor deposited film layer b is Due to the irregularities formed in the metal vapor deposited film layer b, the incident light is beautifully diffused and reflected with a white shining feeling.
A unique, fine-grained light diffused reflection packaging decorative paper, etc., which has never been seen before, can be obtained.

As described above, the present invention includes a first step of depositing a resin mixed with ultrafine particle substances on one surface of a sheet or film material to form a resin film with an ultrafine rough surface;
a second step of forming a metal vapor deposited film on the ultrafine rough resin film transfer surface of the film material obtained in the step using a metal vapor deposition means; After forming a diffusely reflective metal vapor deposited film on a very finely rough surface corresponding to the assembly surface, the deposited film on the very finely rough surface is peeled off from the very finely rough surface of the resin film and transferred to one surface of the adhered member. The third step is adhesion, so conventional methods that give a shiny white appearance to the surface of the adhered material made of organic or inorganic substances such as natural or synthetic paper, cloth, glass, metals, or synthetic resins are applied. Unique to the present invention, it is possible to easily form a metal vapor-deposited film that can reflect light rays in an extremely unpleasant way, and it also has the effect of being able to be processed at a low cost with physical properties that are equivalent to or better than conventional laminated paper. .
