特に、耐汚染性を改善するためには、塗膜表面を親水性化するとよいことが認められているが、これは、汚染回復性（洗浄性）の向上を目的としてなされる処理であり、汚染物質の付着量に対して汚染回復性が上回った場合のみ、耐汚染性の効果が得られる。これに対し、塗膜に撥水・撥油性を持たせる方法によれば、汚染物質が親水性、親油性のいずれの物質であっても、塗膜への付着性を低減させたりすることができる。従来、塗膜への撥水・撥油性の付与は、オイルや界面活性剤の添加によって行われているが、このような方法では、長期にわたって耐汚染性を維持することは困難である。 In particular, in order to improve stain resistance, it is recognized that the surface of the coating film should be made hydrophilic, but this is a treatment performed for the purpose of improving stain recovery (cleanability). The effect of stain resistance can be obtained only when the stain recovery exceeds the amount of contaminants attached. In contrast, according to the method of providing the water and oil repellency to the coating film, contaminants hydrophilic, be any lipophilic substances, be and have it reduce the adhesion to the coating film Can be done. Conventionally, water repellency and oil repellency are imparted to a coating film by adding an oil or a surfactant, but it is difficult to maintain stain resistance for a long period of time by such a method.
