Patent ID: 7241472

Claim:
A process for producing a plastic lens with an antireflection film on a surface thereof, comprising: applying water or an aqueous solution comprising a radical scavenger to a plastic lens having an organosilicon compound-containing hard coat film formed on a surface thereof to form a liquid film of water or the aqueous solution on the surface of the hard coat film, allowing ozone gas to contact with the liquid film so as to treat the surface of the hard coat film with the ozone gas, and forming the antireflection film on the ozone gas treated surface of the hard coat film by vapor deposition wherein the organosilicon compound used to form the hard coat film is at least one compound selected from compounds of general formula (I): (R 1 ) a (R 3 ) b Si(OR 2 ) 4−(a+b) (I) wherein R 1 and R 3 each independently represent a monovalent hydrocarbon group having from 1 to 10 carbon atoms, with or without a functional group; R 2 represents an alkyl group having from 1 to 8 carbon atoms, an aryl group having from 6 to 10 carbon atoms, an aralkyl group having from 7 to 10 carbon atoms or an acyl group having from 1 to 8 carbon atoms; a and b each independently indicate 0 or 1; and a plurality of the OR 2 groups may be the same or different from each other, wherein the hard coat film comprises silicon oxide particles, and wherein the first layer of the vacuum evaporated antireflection film comprises SiO 2 .
