Abstract

PURPOSE:To obtain a vapor deposited film having superior decorativeness by treating the surface of a polyester film having a specified surface roughness by corona discharge and by forming a vapor deposited metallic layer on the treated surface by PVD and a colored layer on the metallic layer with an adhesive. CONSTITUTION:Inert and solid fine particles of 0.05-10mum average particle size are dispersed in biaxially stretchable polyester such as aromatic polyester by 0.003-1.5wt% so as to form a large number of fine projections and a stretched polyester film having 0.00-0.030mum surface roughness Ra is obtd. The surface of the polyester film is treated by corona discharge so that circular or elliptical treated parts of 2-50mm diameter or major axis size are distributed ununiformly and irregularly and account for 10-50% of the area of the whole surface. A vapor deposited metallic layer is then formed on the treated surface of the polyester film by PVD such as vacuum deposition and a colored layer of 1-3mum thickness is formed on the metallic layer with one or more kinds of colorants and an adhesive such as an epoxy resin adhesive.

Description

[Detailed description of the invention] The present invention relates to a vapor-deposited film, and more specifically, a spot corona treatment is applied to 6 times of an oriented polyester having a p-surface roughness (Ha) of 0.005 μm or more. Then gold cormorant#
A layered film suitable for decorative purposes is created by forming a layer of 4℃, which is suitable for decorative purposes. Conventional technology: Vapor deposition has been used to integrate light reflection into the film for applications such as gold and silver threads, immerses, and reflectors. A film is used. The fact that this A'E yN film is used for this purpose, and that it has excellent moxibustion properties, is covered with a lot of reflective paint is 15 (more than 101). First of all, the most important thing is not to cause water sores.
However, vapor-deposited films exclusively cause spotting, and many techniques have been proposed to address these problems.

However, in response to the diversification of lifestyles and tastes, vapor-deposited films have come to be used in various forms in a wide range of fields other than those mentioned above.

As one of the things that can meet this demand, there is a need for an ilm that does not have an artificial, character-like or regular feel (see #5, which irritates the abundance of natural decorative patterns). .

OBJECT OF THE INVENTION The present inventors have discovered that artificial, geometrical or irregular, and other (natural-looking)
As a result of our own research on the #gloss film, we found that by applying a non-uniform and irregular corona treatment to the surface of oriented polyester to achieve a specific surface roughness, we have created a film that has an extremely wide range of decorative patterns. We succeeded in obtaining a vapor-deposited film.

It is an object of the present invention to provide a 76-layer film with a highly natural-looking device tllij pattern gloss useful for decorative applications.

Structure and Effects of the Invention According to the present invention, an object of the present invention is to improve the surface roughness (Ra)
Corona treatment is applied to the surface of an oriented polyester film having a resistance of 0.005 μm or more so that the surface to be treated has a circular or oval shape with a diameter or major axis of 2 to 50 m, or a modified shape thereof, and occupies 10 to 50% of the surface area. This is achieved by a vapor-deposited film in which 1flJ of gold stripes are deposited after the process.

In the present invention, one base film is an oriented polyester film, the surface of which has a surface roughness of 0.005 μrn or more. This polyester is a polyester with a biaxial orientation ability of 7, and aromatic polyesters (eg, polyethylene prephthalate, polytetophmethylene terephthalate).

Polyethylene-2,6-naphthalene dicarphoquinate, etc.) are preferred from the viewpoint of thermal properties and moisture absorption properties. The polyester may contain a stabilizer, a coloring agent, an antioxidant, a dehydrator, and other additives, depending on safety.

The oriented polyester film has many fine protrusions on its surface. The large number of thin protrusions are derived from a large number of substantially inert solid particles that are normally dispersed and contained in the polyester upper.

Polynisal containing a large number of inert solid particles is usually prepared at any time during the reaction to form polynisal, for example, during the transesterification reaction using the ester parent exchange method or during the transesterification reaction, or directly by one method. It can be prepared by adding inert solid particulates (preferably as a slurry in glycol) into the reaction system at any time. Preferably, the inert isomeromimetic particles are added to the reaction system at the beginning of the melonization reaction, for example, until the intrinsic viscosity reaches about 0.3.

A) is important from the viewpoint of quality as a vapor-deposited film, but it is also important from the viewpoint of ease of handling in the film forming process or the Sanno process. Regarding ease of handling in the film forming process or processing process, the combination of surface roughness (Ra) and film thickness may be affected (for example, when the film thickness is about 50 μm or more, the stiffness of the film itself becomes effective). 1, for example, surface roughness (Ha)
Even if it is at a level of 0.01 μm or less, there is no particular problem with its handling. The thickness of the film becomes thinner (as the thickness becomes thinner)

5. Each surface to be treated may be circular or oval (but depending on the processing conditions, the oval may be transformed into an arcuate shape with the flesh side facing the flesh; III: January-shaped or horseshoe-shaped). It can also be shaped and shaped.

Here, the shape of each treated area can be determined by the Jtf+ of the treated area when powdered slaked lime is evenly sprinkled on the film surface after corona treatment. In terms of size, those that can correspond to a circle are measured by the diameter, and those that can correspond to an oval are measured by the major axis.Historically, shapes such as bows, crescents, or ganitetsu are formed by tying their two ends together. Each is expressed by the straight line distance that penetrates the shape the most.The size of this must be 21 or more and 50 or less.If this size is smaller than 2, it is for practical purposes and flow lines. If the film is larger than 50 mm, it is undesirable from the viewpoint of overall decorative balance. b
It is. Even if this percentage is less than 10%, it will still be 50%
Even if it is larger, the decorative effect is 11 points away.

In order to create a decorative seedling on the film surface by non-uniformly and randomly applying corona treatment, the combination of the morphology (size, shape) of the treated area is quite disappointing. Although the effect will not last for a long time,
It can be mentioned that the difference in the vapor deposition properties of the coat-treated part and the non-treated part has a large effect on the decorative properties of the vapor-deposited film.

Coupled with the morphological young pottery that makes it difficult to use, the style of @vermilion is mastered, and the C:h effect is exhibited.

In order to apply uneven and irregular T treatment to the film surface, the shape of the corona discharge electrode, the distance between the electrode and the film, and the running speed of the film k (corner processing speed) are important considerations. Can be mentioned.

The Ministry of the Invention has also discussed these causes of indignation in detail. 7=j
It is suitable that the width of L or I is in the range of 5 mm to 1 mm. It is good to know that if the distance between the electrode and the tool is 1.5m + mL'J or vc-;', the JP beam will be treated unevenly, the temperature used, and the above Wa is t. A series of electrodes are arranged irregularly in a range of about 5 u and the width of the electrodes is over 1.5 degrees Celsius and the distance between them and the running column is about 5 u.

Corona treatment 1c'C is preferably carried out using this section. At that time, for 7 films with a film thickness of 25 μm or less, especially less than 20 μm, it is necessary to provide unevenness on the treatment roll. It is also possible to increase the distance between the 'C electrode and the film by 1.Also, regarding the processing speed of the film (Kengyoren If), it is possible to increase the film processing speed (Kengyoren If) by increasing the distance between the film and the 'C electrode. There are no major restrictions on the ox other than the need to be careful not to cause trouble, but considering productivity, it is desirable to have a speed of 1 IJ Om/min or more. In order to achieve this effect, it is best to change the speed continuously or discontinuously to bring about mechanically small periodicity over 200m/"y and 300m/min. The applied voltage may be appropriately set in consideration of the film running speed.

In the present invention, a metal vapor deposition layer is provided on the film surface after the above-mentioned corona treatment, but as a method for forming four metal films on the film surface, the physical layer method, for example,
Vacuum deposition method, sputtering method, etc. are usually used.

In the case of the vacuum deposition method, the heat of the evaporation source is preferably generated by electron beam heating.
From the range of IJ' to lXIU-' Torr, the evaporation source temperature is appropriately selected from the range of 1,4 tiO to 1,800°C.
