SYNTHETIC RESIN LENS AND PROCESS FOR PRODUCING THE SAME
A synthetic resin lens which has a high refractive index, a low specific gravity, and excellent transparency, is reduced in the dispersion of light, and is easily molded through cast polymerization without causing the sealing material to dissolve away or be damaged. The synthetic resin lens is chara...

| description | A synthetic resin lens which has a high refractive index, a low specific gravity, and excellent transparency, is reduced in the dispersion of light, and is easily molded through cast polymerization without causing the sealing material to dissolve away or be damaged. The synthetic resin lens is characterized by being obtained by polymerizing a monomer mixture comprising [A] a polyfunctional (meth)acrylate having a urethane bond, [B] divinylbenzene, and [C] a polythiol compound using a radical polymerization initiator.
La présente invention concerne une lentille en résine synthétique présentant un indice de réfraction élevé, une faible densité, une excellente transparence, une dispersion de lumière réduite, et qui peut facilement être moulée par polymérisation du produit de coulée sans que le matériau de scellement se dissolve ou s'abîme. La lentille en résine synthétique de la présente invention est caractérisée en ce qu'on l'obtient en polymérisant, à l'aide d'un radical initiateur de polymérisation, un mélange monomère comprenant (a) un (méth)acrylate polyfonctionnel à liaison uréthane, (b) un divinylbenzène, et (c) un composé polythiol. |
