ルムに関するものである。DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention has the ability to suppress the fog generation phenomenon near the inner surface of the coating material (this ability is referred to as fog prevention property) for a long period of time. The present invention relates to an excellent vinyl chloride resin film for agricultural use.

テルなど。）を含んでいる。"Prior Art" In recent years, in order to efficiently cultivate existing plants, accelerated cultivation in greenhouses or tunnels has become popular. A vinyl chloride resin film is often used as a material for covering the house or tunnel because of its excellent weather resistance, transparency, heat retention, strength, etc. Most of the vinyl chloride resin films currently in use are designed to promote the flow of water droplets on the inner surface of the coating material (the surface facing the inside of a house or tunnel) and increase the amount of sunlight incident on it. It also contains an antifogging agent (mainly sorbitan fatty acid ester; glycerin fatty acid ester, etc.), which is a type of surfactant.

。Under a covering material containing such an antifogging agent, a phenomenon in which fog is generated near the inner surface of the covering material is often observed when the temperature difference between the inside and outside of the covering material becomes large.

とによるものと推定される。This fog phenomenon often occurs in late autumn or winter, which is the most important period for greenhouse cultivation, tunnel cultivation, and other facility cultivation. The causes of the fog generation phenomenon are not precisely known, but include the temperature and humidity inside the house or tunnel, the temperature and moisture content of the soil inside the house or tunnel, the amount of solar radiation to the house or tunnel, and the hydrophilicity of the wet surface of the covering material. The humidity inside the house or tunnel adheres smoothly to the surface of the sheathing material due to temperature changes, and some of the moisture becomes mist near the inner surface of the sheathing material. It is presumed that this is due to the following.

内の見通しが悪くなるため、農作業の能率が低下する等
の弊害もある。Such fog generation phenomenon wets the leaves, stems, flowers, fruits, etc. of useful crops grown in greenhouses or tunnels, causing disease outbreaks and also aiding in the spread of disease outbreaks. Also, if the cultivated crops become wet, the heat required to dry them is disadvantageous, such as the need for more fuel for heating the greenhouse or tunnel. Furthermore, since the visibility inside the greenhouse becomes poor, there are also disadvantages such as a decrease in the efficiency of agricultural work.

生現象を完全に抑えるには、有効なものではなかった。To overcome these disadvantages, conventional methods have been to use colored synthetic agricultural resin films or cover the soil inside greenhouses or tunnels with mulching films in order to soften temperature changes inside greenhouses or tunnels. The amount of evaporation of water can be reduced by
Measures have been taken to improve irrigation methods and equipment (e.g., adjusting the volume of water), irrigation methods, and equipment. However, none of these methods was effective in completely suppressing the fog generation phenomenon.

の低下が著しい。[Problems to be Solved by the Invention] However, according to experiments by the present inventors, when an antifogging agent is further combined with a fluorosurfactant or a copolymerized oligomer, agricultural vinyl chloride resin coatings It may have a negative effect on the anti-fog property, which is an essential performance for the material, and the anti-fog property will not deteriorate much even if used in the low temperature winter, but if you start using it in the high temperature summer or early autumn. It has been found that the deterioration of anti-fogging properties is accelerated and the durability of anti-fogging may be markedly inferior. By reducing the amount of fluorosurfactant or copolymerized oligomer blended, the negative effect on antifogging properties can be reduced, but the fog generation suppression effect is not satisfactory, especially when used for a long period of time. There is a significant decrease in fog resistance.

に至ったものである。``Means for Solving the Problems J'' Under such circumstances, the present inventors have developed an agricultural vinyl chloride resin coating material that does not reduce the anti-fog durability and exhibits anti-fog properties over a long period of time. As a result of intensive studies with the aim of providing a solution, we found that even when a small amount of fluorine-based surfactant or copolymerized oligomer is blended, the anti-fogging properties are impaired by co-blending benzoxazole derivatives and β-diketone compounds. The present invention was completed based on the discovery that the anti-fog property can be exhibited for a long period of time without any problems.

However, the deterioration in fog resistance is small. Its suppressive effect is extremely strong, and it can virtually completely suppress the occurrence of fog even in late autumn and winter, when it has traditionally been said that fog frequently occurs, and it has a remarkable effect on preventing the occurrence and spread of diseases on plants. There is. Therefore,
There is no need to pay close attention to irrigation, etc. as in the past.
