。Conventionally, soft resin films such as vinyl chloride resin films and ethylene resin films have been frequently used as covering materials for greenhouse horticulture. The synthetic resin film usually contains a nonionic surfactant such as sorbitan or glycerin in order to prevent fogging caused by water droplets adhering to the film surface. In addition, in order to prevent the moisture in the air inside the greenhouse from liquefying due to temperature differences inside and outside the greenhouse and floating inside the greenhouse in the form of mist, we have developed a limb covering material containing a silicone surfactant (Japanese Patent Laid-Open Publication No. 1983-1992). No. 91663), a coating material kneaded with a fluorine-based surfactant containing a perfluoroalkyl group or a perfluoroalkenyl group (Japanese Patent Publication No. 1983,
An agricultural and horticultural film (Japanese Patent Publication No. 62-18579) has been proposed, which contains a copolymerized oligomer of acrylate or methacrylate-1 containing a terminal perfluoro group and a compound that can be copolymerized. ing.

由は明確でない。The inventor of the present invention found that the antifogging performance of the coating film added with the above-mentioned silicone-based and fluorine-based compounds is partially reduced when the temperature inside the greenhouse rises, causing droplets to form. There has been a problem in that a phenomenon in which the state changes (hereinafter this phenomenon may be referred to as high-temperature damage) occurs. Since greenhouses are facilities whose main purpose is to maintain heat, each crop is maintained within the maximum and minimum temperature ranges suitable for cultivation. Particularly during the daytime hours when the sun is shining, efforts are made to manage the temperature inside the greenhouse so that the temperature rises to the maximum temperature that is appropriate for the growth stage of the crop, in order to ensure the lowest nighttime temperature. . When the inside of the greenhouse is kept under high temperature control and the anti-fogging properties of the inner surface of the film are reduced due to the occurrence of high temperature damage, water droplets will fall from the part of the film where the high temperature damage has occurred, hitting the crops planted at the bottom of the drop, causing the crops to fall. It is susceptible to sclerotia, gray mold, etc., and may even die off, so the occurrence of high-temperature damage is a serious problem. However, the reason why an antifogging film provided with antifogging properties tends to lose its antifogging properties in a portion of the film under high temperature conditions and cause a dripping state to occur is not clear.

Per 100 parts by weight of synthetic resin, 0.5 to 5 parts by weight of a hydrocarbon nonionic surfactant and 0.01 to 5 parts by weight of a fluorine-containing compound containing a perfluoroalkoxy group having 2 to 6 carbon atoms.
The inventors have discovered that a synthetic resin film containing 0.5 parts by weight can solve these problems, leading to the present invention.

り0.5〜5重量部の範囲で用いる。The hydrocarbon-based nonionic surfactant must be able to prevent deterioration of the weather resistance of the film as much as possible and have excellent anti-fogging properties, such as sorbitan monopalmitate, sorbitan monostearate, and sorbitan monobehenate. , sorbitan surfactants such as sorbitane dipalmitate, sorbitane distearate, sorbitane dibehenate, glycerin surfactants such as glycerin monopalmitate, glycerin monostearate, diglycerin monostearate, diglycerin distearate, etc. polyethylene glycol surfactants such as polyethylene glycol monopalmitate and polyethylene glycol monostearate, and esters of sorbitan/glycerin condensates and organic acids. These surfactants can be used alone or in combination of two or more. The hydrocarbon nonionic surfactant is used in an amount of 0.5 to 5 parts by weight per 100 parts by weight of the synthetic resin.
0.5重量部より少ないと充分な防曇持続性が得られな

Moreover, it is unsuitable because it causes a bloom phenomenon on the film surface and promotes staining of the film.
