Abstract

Liquid composition polymerizable into organic glasses with a refractive index (nD20) ≥ 1.53 comprising: from 30 % to 90 % by weight of an allyl ester of an aromatic dicarboxylic or tricarboxylic acid having general formula (I): wherein R represents a radical of a dicarboxylic or tricarboxylic acid, and n is 2 or 3; from 10 % to 60 % by weight of bis(allyl carbonate) of an aliphatic or aromatic dihydroxylic alcohol, oligomeric or essentially oligomeric, having general formula (II), wherein R' represents a radical of an aliphatic or aromatic dihydroxylic alcohol a radical of an aliphatic or aromatic dihydroxylic alcohol and n is an integer or a fraction ranging from 2 to 10 extremes included, preferably from 2 to 5 extremes included; (C) from 0.5 % to 5 % by weight and preferably from 1 % to 3 % by weight of an organic peroxide belonging to the group of perketals; (D) from 0 ppm to 10 ppm of an organic dyes or a mixture of dye soluble in said liquid composition.
