・In particular, interior materials for buildings, vehicles, ships, etc., stereos,
The surfaces of home appliances such as televisions, refrigerators, air-conditioning equipment, vending machines, furniture, fittings, tables, musical instruments, cabinets, etc. are beautifully decorated, and their surfaces are free from various pollutants during use. There is a strong desire for it to be protected and to maintain its beauty for a long period of time. For this purpose, methacrylic films mainly made of methyl methacrylate, which have good weather resistance, polyester films that are strong and have good surface gloss, and vinyl chloride films, which have good surface embossing properties, are laminated and used. However, it was not sufficient in terms of stain resistance and abrasion resistance. In particular, the above-mentioned items used at home or in public gathering places are mainly contaminated with oily dirt such as dust in the air, cigarette smoke, hand grime, volatile components during cooking, various foods, and household goods. The currently used film laminates described above have poor resistance to these contaminants, which over time penetrate the surface film layer and cause permanent contamination. The only exception is fluorine-based film laminated products, which have excellent resistance to this type of contamination, but are expensive and have poor adhesion during lamination and poor surface printability. This is considered a drawback. The present inventors have intensively researched economical surface lamination materials from the above viewpoint, and have found that a polyacrylonitrile film with a limited composition has extremely superior stain resistance compared to conventional synthetic resin films. Then, the film of limited thickness was strongly adhered and laminated with a different film having characteristics to overcome the defects of the film as described below.
5. We have found that the above object can be achieved by doing the following, and have completed the present invention. It is known that polyacrylonitrile films have excellent chemical resistance, dimensional stability, light resistance, abrasion resistance, etc., and are effective for surface decoration or lamination.

However, since such films generally have low elongation and poor thermoplasticity, cracks may occur during mechanical processing such as bending or drawing after lamination, especially when laminated onto metal surfaces, and cracks may occur during embossing. It has drawbacks such as lack of surface workability, and is not suitable for use as a single layer film for such purposes. The present inventors investigated these problems and found that (1) a film of an acrylonitrile polymer or copolymer with a high component ratio is used as thin as possible for the surface layer, and (2) ) By laminating a relatively thick film with high elongation and good heat processability such as embossing, between the surface layer and the bottom base material, it is possible to protect the underlying base material and improve machinability and surface workability. (3) Solve the processability problem of the surface layer by firmly bonding the above surface layer, intermediate layer, and base material with adhesive, resulting in improved stain resistance and processability. It was found that a surface decoration with excellent properties and design was possible.

Methods for producing films from these polymers are readily known, for example casting from a solution of the polymer in an organic solvent, or hot melt extrusion from a polymer plasticized with a plasticizer, a high-boiling solvent. A film formed by a molding method or the like and preferably biaxially stretched can be used. 5 weight for the film? Additives such as lubricants, plasticizers, antistatic agents, dyes, and pigments may also be included. Acrylonitrile unit 85 weight? A film formed from an acrylonitrile copolymer having a concentration of less than 10% is not suitable because the stain resistance, which is a feature of the present invention, is not as excellent as that of conventionally used polyester films. The acrylonitrile film is oriented in the range of 2.5 to 4 times in both the vertical and horizontal directions,
It is desirable that the material is then heat-treated and used in a state in which the heat shrinkage rate is suppressed to about 5% or less.

The thickness of the film is used for the purpose of protecting the surface layer of the laminate from contaminants, so a thin film is sufficient;
A thick film is undesirable because it is more likely to crack or crack during mechanical processing such as bending or drawing as a laminate, and its secondary processability such as embossing is reduced.

Since the film has excellent printability with various inks, extremely delicate printing is possible and a highly decorative surface decoration can be provided. The adhesive strength of the above two types of films is 18" peel strength 0.5 kg/
It is necessary to have adhesive strength equal to or higher than CTIl. If the adhesive strength is low, the acrylonitrile film forming the surface layer of the laminate will bend and peel because it cannot follow the deformation of the base during drawing, resulting in cracks or cracks. The thickness of the adhesive layer is not particularly limited in the present invention, but is suitably about 0.5 to 20 microns, preferably about 1 to 10 microns.

The film is produced by homogeneously mixing 100 parts by weight of the above copolymer, 24 parts by weight of ethylene carbonate, and 10 parts by weight of water, plasticizing it, forming it into a sheet by a conventional extrusion method, and then sequentially increasing the length by 3 times in each direction. The film was stretched, heat-set under tension, and dried, and the remaining ethylene carbonate was 1.5%. First, the adhesive surface of the film (thickness: 15.30μ) was subjected to corona discharge treatment, and then a two-component curing type urethane adhesive was applied and dried using a doctor knife, and 80μ of both sides were oxidized. It was laminated by passing it between a density polyethylene film and a heated nip roll. The amount of adhesive applied was 3.5 g/m'', and the 1800 peel strength of the laminated film was 0.75k9/CTIL. Next, an ethylene-vinyl acetate hot melt adhesive was applied to the polyethylene side of the laminated film. Application amount 12f1 using roller coating method
/wl and applied onto a mild steel plate preheated to 150℃ with a surface thickness of 10kg/C! They were bonded together at a pressure of 1. Table 1 shows the physical properties of the laminate. As comparative samples, a laminate product laminated in the same manner as above (Comparative Example 1) except that the above acrylonitrile copolymer film was not subjected to corona discharge treatment, and a 50μ acrylonitrile copolymer film in the same manner as above were used. A laminate product (Comparative Example 2), a laminate product in which films extruded by thermoforming from an acrylonitrile-methyl acrylate copolymer with an acrylonitrile composition ratio of 80% and biaxially stretched are laminated by the above method (Comparative Example 3) Table 1 shows the physical properties of a laminate (Comparative Example 4) in which a 25 μm polyester film was used in place of the acrylonitrile film described above. These results show that the laminate of the present invention has significantly higher surface hardness than conventional laminates made of polyester films, has excellent abrasion resistance and stain resistance, and has excellent bending processability. It can be seen that it also has embossability.

On the other hand, if the adhesive strength between the acrylonitrile film and the polyethylene film is low, or if the acrylonitrile film is thick, the above secondary processability will be poor, and if the acrylonitrile component ratio of the acrylonitrile film is low, the abrasion resistance and stain resistance will be poor. shows that it is inferior.

For convenience, all of the laminates shown in Table 2 were bonded to mild steel plates using a phenolic adhesive, but the method of bonding to such a substrate is not particularly limited in the present invention. Further, for reference, the physical properties of laminated products obtained by conventional lamination methods are shown in Comparative Examples 7 to 11. The results in Table 2 also show that while conventional laminate products have defects in any of the performance items shown in Table 2, the laminate product of the present invention has satisfactory performance in all of them. I understand.
