Light shielding lens for protective eyeglasses

Номер: US20130194658A1
Автор: Kanichi Tamura, Kenzo Wada, Shoichi Mitsuuchi
Принадлежит: Talex Optical Co Ltd

A light-shielding lens which can cut ultraviolet or visible radiation having wavelengths of 430 nm and shorter or of 500 nm and shorter and which can sufficiently satisfy users' demand for its color. The lens contains 0.01 to 2 parts by mass of an indole-based ultraviolet absorbing dye having a melting point of 140 to 150° C., based on 100 parts by mass of a synthetic resin forming the lens, and preferably further contains an oil-soluble dye, whereby the lens can cut ultraviolet and visible radiation having wavelengths of 430 nm and shorter. Since the predetermined amount of the indole-based ultraviolet absorbing dye is sufficiently dissolved in the synthetic resin, it efficiently reveals its expected function. The lens can thus cut ultraviolet and visible radiation having wavelengths of 430 nm and shorter, or even 500 nm and shorter, while keeping highly transparent light color.

A functional laminated spectacle lens is provided which includes, as constituent layers, an outer lens, a polarizing film, and an inner lens. A functional layer is formed on at least one of the constituent layers. Another constituent layer is laminated on and joined to the functional layer through an adhesive layer. The functional layer is formed using a spin coating material which is obtained by incorporating a functional pigment into an acrylic urethane resin containing, as a main component, an acrylic polyol containing 4-hydroxybutyl acrylate, and, as a curable component, a polyisocyanate. Once the spin coating material cures, the required functional pigment is reliably maintained in the functional layer by a three-dimensional network structure, the migration of the functional pigment into an adjacent resin monomer-containing layer is prevented, and the functional pigment is made less susceptible to the effect of an organic peroxide contained in the resin.
