PURPOSE:To obtain the titled plastic lens having excellent resistance to abrasion, high-temp. water, and weather and excellent dyeability by applying an antifogging coated film consisting essentially of a specified organic silicon compd. CONSTITUTION:An antifogging coated film to be applied consists essentially of (A) one or >=2 kinds of organic silicon compds. shown by the general formula (where, R<1> is 1-6C hydrocarbonic group, vinyl group, methacryloxy group, or an organic group having an epoxy group, R<2> is 1-4C hydrocarbonic group, R<3> is 1-5C hydrocarbonic group, alkoxylalkyl group or hydrogen atom, and (l) shows 0 or 1), (B) colloidal silica having 1-100mum particle diameter, (C) polyhydric alcohol or polyhydric alcohol having an ethylene oxide group, and (D) magnesium perchlorate. Dew is not deposited on the surface of a lens due to the water vapor in air, even when the surface temp. becomes lower than the dew point in the environment. The plastic lens whose transparency is not lost can be obtained in this way. |
