用合成樹脂フィルムに関するものである。Detailed Description of the Invention [Object of the Invention] (Industrial Field of Application) The present invention relates to a synthetic resin film for agricultural use, and more specifically, a polyfluoroalkyl film having 1 to 20 carbon atoms is added to a synthetic resin film base. The present invention relates to a fog-proof agricultural synthetic resin film comprising a fluorine-containing polyester oligomer obtained by condensing a lactone compound with a fluorine-containing alcohol compound having a group and a hydroxyl group.

めのハウス栽培用のフィルムとして使用されている。(Prior art) Vinyl chloride resins and polyolefin resins are relatively inexpensive and have excellent transparency, weather resistance, mechanical strength, etc., so they can be used for stimulated, semi-forced or suppressed cultivation of agricultural crops such as vegetables and fruit trees. It is used as a film for greenhouse cultivation.

テル等）がフィルム基材に配合されている。The films used in these agricultural greenhouses tend to become cloudy when fog generated inside the greenhouse condenses on the inner surface of the film, that is, water droplets adhere to the inner surface of the film. This results in a decrease in sunlight transmittance, which adversely affects the growth of agricultural crops. In order to prevent this dew condensation, a surfactant (for example, sorbitan fatty acid ester, glycerin fatty acid ester, etc.), which is generally called an antifogging agent, is blended into the film base material.

っている。However, although it is effective in preventing dew condensation in agricultural greenhouses spread with synthetic resin films containing such antifogging agents, it is difficult to remove the film during the mornings and evenings from autumn to winter when the temperature difference between the inside and outside of the film is large. A lot of fog is generated near the inner surface, and the problem is how to prevent it.

題となっている。This phenomenon of fog formation not only reduces the transmittance of sunlight and deteriorates the working environment for agricultural work, but also causes the occurrence of various diseases by wetting the crops grown in greenhouses, which has become a serious problem.

提案されているが、十分なものとはいえない。In order to prevent such fog generation, a method of kneading a small amount of fluorine-based surfactant into a synthetic resin film has been proposed, for example, in Japanese Patent Publication No. 59-35573 and Japanese Patent Application Laid-open No. 57-192445. It cannot be called a thing.

Furthermore, fluorine-based surfactants have poor compatibility with synthetic resins such as vinyl chloride resin, so adding them may reduce the transparency of the film.
There is a problem that it bleeds and falls off the resin surface, so that the anti-fog effect does not last.

た。In view of the above circumstances, the present inventors have conducted intensive research to develop a fluorine-based fog-proofing agent that has superior fog-proofing properties than fluorine-based surfactants and is also more compatible with synthetic resins. The present inventors have discovered that a fluorine-containing polyester oligomer satisfies these requirements, and have completed the present invention.
