PROBLEM TO BE SOLVED: To provide an anti-fouling agent excellent in anti-fouling capability of vehicle body of automobile or the like, that never allows water droplet to damage the painted surface, or never allows ring-shaped stain to occur.SOLUTION: The anti-fouling agent was invented by paying attention to making the body surface into a hydrophobic state in which the surface is more friendly to water than a water-repellent state, and by using a polyamine compound as a suitable anti-fouling agent that can make the surface into hydrophobic state, and efficiently making the vehicle body surface into hydrophobic. Furthermore, the anti-fouling agent preferably contains non-ionic surfactant, and also further preferably contains water. The anti-fouling agent preferably has a contact angle for water on the painted film surface of 80° or less.

    【課題】水滴により塗装表面を傷めたりリング状のシミが発生したりすることがない、自動車等の車両車体の防汚性に優れた防汚剤を提供する。【解決手段】車体表面を撥水状態よりも水になじみ易い、疎水状態にすることに着目し、疎水状態にし得る好適な防汚剤防汚剤としてポリアミン化合物を使用することで車体表面を効率的に疎水化した。更に、非イオン界面活性剤を含有することが好ましく、また、更に、水を含有することが好ましい。本発明の防汚剤は、塗膜表面の水に対する接触角が80?以下であることが好ましい。【選択図】なし
