Abstract

PURPOSE: The title composition usable for plastic lenses, having improved resistance to scuffing, flexibility, and transparency, comprising a specific hydrolyzate, an epoxy compound, finely divided silica, and an aluminum chelate compound.
CONSTITUTION: A composition comprising (A) a hydrolyzate of formula I (n is 0 or 1; R is 1W4C alkyl or alkoxyalkyl group), e.g. γ-glycidoxypropylmethyldiethoxysilame, (B) an epoxy compound of formula II (R1, R2, and R3 are H or CH3; n is an integer ≥0), having an epoxy equivalent ≤400, e.g. a condensate of bisphenol A with epichlorohydrin, (C) finely divided silica, preferably silica sol having a particle size of about 1W100mμ, and (D) an aluminum chelate compound of formula III. The preferred weight ratios are as follows: (B) is 10W80% based on (A); (C) is 10W200% based on the total (A) and (B); (D) being 0.1W20% based on the total (A), (B), and (C).
