PURPOSE: To provide an antifouling paint which has excellent adhesion and crack resistance and gives a dry film having a specified glass transition temp., by using a high-molecular organotin compd. as a vehicle.
CONSTITUTION: An antifouling paint which gives a dry film having a glass transition temp. of -15W35°C, pref. -5W25°C, is obtd. by using a high-molecular organotin compd. as a vehicle and optionally adding an antifouling agent. When the Tg of the film is higher than 35°C, the film is not flexible and cracked after immersed in seawater, thus causing the peeling or adhesion failure of the film. When Tg is lower than -15°C, the film is not dried and hence the paint cannot be put to practical use. The film can be softened by controlling the Tg of the high-molecular organotin compd. serving as a vechicle or adding a Tg modifier.
