Abstract

PURPOSE: A hard coating agent which gives a film having good adhesion, hardness, resistance to warm water, resistance to oil or the like and is suitable for making plastic lens, by blending an organic silane compound and a Ta or Nb alcoholate as a polymerization initiator.
CONSTITUTION: A desired agent is prepared by blending about 20W90wt% organic silane compound (e.g. γ-glycidoxypropyltrimethoxysilane) of formulaI(where R is an organic group containing a glycidyl radical; R' is a 1W8C alkyl), about 2W50wt% organic silane compound (e.g. tetramethoxysilane) of formula II and about 1W20wt% metal alcoholate (e.g. pentaethoxytantalum) of formula III (where Me is Ta, Nb). The obtained coating agent is dissolved in an organic solvent, applied onto a plastic plate, and polymerized to give a uniform and rigid film.
