【発明の詳細な説明】 〔産業上の利用分野〕 本発明は農業用フィルムに関する。[Detailed description of the invention] [Industrial application field] FIELD OF THE INVENTION The present invention relates to agricultural films.

破損する。これの改良のため各種の耐候性安定剤（劣化
防止剤）が開発され、フィルム中に添加利用されている
。これを大別すると以下の２種類がある。Required for agricultural films made of thermoplastic resin. The most important property is durability. The film deteriorates due to ultraviolet rays in sunlight in the presence of oxygen in the air, resulting in a decrease in strength and elongation and breakage. To improve this, various weather-resistant stabilizers (deterioration inhibitors) have been developed and are used as additives in films. This can be broadly classified into the following two types.
■′紫外線吸収剤： 紫外線を吸収しカントすることに
より劣化の開始を抑え耐候性を改良する。■'Ultraviolet absorber: By absorbing and canting ultraviolet rays, it suppresses the onset of deterioration and improves weather resistance.
農業用フィルムは薄いため（約２０〜１５０μ程度が多

効果が低い。もしも十分なカットレベルまで吸収剤を添
加するとフィルム表面へのブリード白化とコストアップ
が問題である。Because agricultural films are thin (often about 20 to 150 microns), it is difficult to sufficiently cut and remove ultraviolet rays, and the improvement effect is low. If the absorbent is added to a sufficient cutting level, there will be problems such as whitening due to bleeding on the film surface and increased cost.

約５μｍ以下が望ましい。The desirable shape of these fine powders is that in order to fully demonstrate the performance of preventing pesticide damage, a larger surface area is better for the same amount added, and the particle size should be as small as possible within the range where secondary aggregation does not become a problem. The surface area should be as large as possible. There is no particular limitation, as long as it does not adversely affect the film appearance, elongation, moldability, etc. However, from the viewpoint of film transparency and appearance, the particle size is desirably about 5 μm or less.

A range of B=about 0.1 to 1.0% is preferred. The general method of adding the hydrotalcium +-a compound is to uniformly disperse and mix it together with the hindered amine stabilizer a in the film 1 as shown in the first diagram. Another method is to use hydrotalcite compounds in Figure 2 (A) (E
l) It can be used by concentrating NLa on one side of the film as shown, or on both sides as shown in the third figure, with a hindered amine stabilizer, etc., and dispersing and mixing. This way,
It can more effectively prevent the effects of external pesticides, and is effective even if the total amount added is small.
