Document Type and Number:

Japanese Patent JP2003506499

Kind Code:

A

Abstract:

Polymerizable compositions for making transparent polymeric substrates, resulting transparent polymeric substrates and the applications thereof in optics. The composition comprises: from 35 to 70 parts by weight of one or more monomers (I) of formula: wherein R₁and R₂represent H or CH₃, A is a divalent moiety of formula: m1 and m2 each are an integer in the range of 4 to 20, from 5 to 50 parts by weight of a monomer (II) comprising at least a urethane unit and at least two (meth)acrylate functions, and from 5 to 40 parts by weight of a monomer (III) with a high Abbe number and comprising one or more methacrylate functions, the total of the monomers (I), (II) and (III) representing 100 parts by weight.
