化しない。同様な効果が３Ａ。When Zn or Sn is ion-irradiated, the contact angle of water to the irradiated surface of soda-lime glass increases significantly, indicating good water repellency. Furthermore, the water repellency remains unchanged even after the heat resistance test at 100°C. Similar effect is 3A.

合視認性が悪い。The water repellency of the irradiated surface is inferior to that in the case of ion irradiation with elements belonging to group (2) in Table 1, which are the elements described in the claims. If the contact angle is from 20° to less than 70°, it will be in a transitional state between water repellency and hydrophilicity, resulting in poor visibility when water droplets adhere.
上記比較例ではその範囲の接触角に近く、好ましい撥水

く変化する条件下においてもその作用は変らない。However, the surface energy of the inorganic glass irradiated with the elements of groups I, ■, ■, and ■ in Table 1 decreases. When water adheres to the surface under the above environment, the cohesive energy of the water is greater than the surface energy of the glass, and as a result, particles tend to gather and form large water droplets that flow downward and remain easy to see. Furthermore, its action remains unchanged even under conditions where the outdoor temperature changes significantly.
