2. Description of the Related Art In recent years, interest in environmental preservation and environmental hygiene has increased, and many products for deodorizing harmful bacteria and the like have been developed. Many of these use chemicals, so that the toxicity and side effects of those chemicals are a problem, antibacterial agents migrate to the support surface, and the impact on the environment can not be ignored And so on. In order to solve the above-mentioned problems, many products using inorganic substances have been proposed, but the method of using the same is difficult, and when used as it is, there is a problem in durability due to separation from the product and the like. When kneading into a polymer to increase the use of the antibacterial agent, if there is a problem such as a decrease in the effect, or if the effect of the antibacterial agent is enhanced, the transparency of the antibacterial layer decreases. Often there was a problem.

[0008] The metal-deposited thin film layer provided on at least one side of the substrate film of the present invention is made of aluminum, silver, tin,
It consists of one or more metals selected as appropriate from metals such as indium, gold, chromium, zinc, titanium, copper and their alloys and mixtures. Its thickness is 1
When the thickness is less than 1 nm, the effect of providing the metal-deposited thin film layer is extremely small. When the thickness exceeds 200 nm, the layer is cracked or the effect of the metal-deposited thin film layer is not further improved. Often, it is not economically feasible. The antibacterial layer provided on at least one surface of the base film of the present invention has an effective antibacterial property,
An anti-microbial agent that is extremely thin, highly transparent and contains an anti-microbial agent at a very low concentration. The anti-microbial agent is contained in the binder component and formed on the film by coating (printing). The antibacterial agent as the material has a sustained release property, the haze value of the antibacterial layer is 10% or less, and an antibacterial layer sufficient for antibacterial property can be imparted to the film. It is not particularly limited as long as it is an antibacterial agent having a film of aluminosilicate impregnated, and the antibacterial metal is silver, copper, at least one metal selected from zinc, for example, Bactenone manufactured by JEOL Ltd. can be used very preferably. An antibacterial agent having an aluminosilicate film in which antibacterial metal ions are added to the silica gel and having an average particle size of 0.5 to 3 μm is excellent in miscibility with a binder resin and a solvent, and The antibacterial property can be sufficiently imparted to the film without extremely lowering the haze value of the antibacterial layer, and can be preferably applied. Thus, when a metal-deposited thin film layer and an antimicrobial layer are sequentially provided on a film, antimicrobial properties can be imparted without significantly reducing the glitter of the metal-deposited thin film layer.

The binder resin is not particularly limited as long as the haze value does not exceed 10% when formed on the film as an antibacterial layer. Examples of the binder resin include polyurethane resins, polyacrylic resins and polyester resins. They can be appropriately selected and used. If the haze value exceeds 10%, the opacity is increased, and the luster of the metal-deposited thin film layer provided thereunder is often impaired. Therefore, there are many problems in decorativeness when the film is formed into a slit yarn. In a preferred embodiment, the 45 ° reflectance on the metal-deposited thin film layer side is preferably 70% or more, and more preferably 90% or more. The thickness of the antibacterial layer is not particularly limited, but is 0.05 μm.
When the thickness is less than 0.05 μm, the haze value is preferably low, but the durability of the antibacterial property is not sufficient. ,
In many cases, the slit yarn is not preferable in terms of flexibility, and is disadvantageous in terms of economy. The antimicrobial layer may be formed on the entire surface of the film or may be partially provided in a pattern.

* Evaluation Evaluation of antibacterial property "Film adhesion method" Each film obtained in Examples and Comparative Examples was 5 cm x 5 cm.
A sample cut into a square was used as a sample. Each sample was subjected to the following antibacterial test. << Antibacterial Test >> Test bacteria: Escherichia coil IFO 3972 was cultured in NB medium (peptone 1%, meat extract 0.5%, salt 0.5%) diluted 500-fold with sterile purified water to determine the number of bacteria. One drop (approximately 0.5
ml) dropped covered with a sterile film on thereon, and measuring the number of initial bacteria immediately after dropping and (N 0), further 35 ° C.,
The number of bacteria after standing at RH 90% for 24 hours was measured (N 24
), And antibacterial properties were evaluated. The result is the initial number of bacteria N
0 is 4.35 × 10 5 for each sample, and the average value (average of 5 points) of the number of bacteria N 24 after standing for 24 hours is 2.5 × 10 7 in Comparative Example 1; Were 10 or less.
