Used by positioning in front of the screen of a display device such as a computer or word processor
Front plates for CRTs are used to reduce eye strain for display equipment operators. As such a front plate, for example, a light-transmitting plate in which a methacrylic resin plate and a polarizing plate are bonded is used. However, conventional light-transmitting plates of this type have poor heat resistance and have the disadvantage that they tend to peel off from the adhesive layer between the polarizing plate and the methacrylic resin plate during the vapor deposition process of a metal compound onto the light-transmitting plate.

According to the present invention, these objects are achieved by a transparent plate having polarizing properties, which is characterized by having a polyurethane adhesive layer 2 between a lead-containing methacrylic resin layer 1 and a polarizing layer 3. This is achieved by the light transmitting plate having polarizing properties as set forth in claim 1 of the utility model registration, which further has a vapor deposited film 4 of a metal compound on the surface of the lead methacrylic resin layer 1.

前面板として好ましい。 When a lead-containing methacrylic resin board is used as the methacrylic resin board, it has greater adhesive strength with polyurethane adhesive than a normal methacrylic resin board,
Furthermore, since it can block minute amounts of X-rays emitted from cathode ray tubes, transparent plates made of lead-containing methacrylic resin plates, polarizing plates, and polyurethane adhesive layers can be used with CRTs.

わせた板である。 A linear polarizing plate that shows linearly polarized light is a polymeric dichroic polarizing film made by adsorbing iodine molecules onto a polyvinyl alcohol film, or a polyvinylene polarizing film with cellulose acetate as a support.
This is a board made by pasting together cellulose-based films such as cellulose triacetate and cellulose acetate butyrate, acrylic films, and vinyl chloride films.

る。 A circularly polarizing plate is a single plate made by combining a linearly polarizing plate and a 1/4λ plate at an angle of 45° with the linear polarization axis. The 1/4λ plate is a colorless and transparent birefringent plate that optically produces a path difference of 1473 Å, which corresponds to 1/4λ of the D-line of Na. A laminate of a circularly polarizing plate and a lead-containing methacrylic resin plate blocks reflected light from a cathode ray tube, and is therefore particularly suitable as a front plate for a CRT.

ての性能を付与することができる。 2 is a polyurethane adhesive layer. As the polyurethane adhesive, isocyanate-modified polymers may be used. Isocyanate-modified polymers are made by subjecting bifunctional or higher-functional polyesters and polyethers to a chain extension reaction with isocyanate compounds such as tolylene diisocyanate to form polymers with active hydrogen groups such as hydroxyl groups at the ends. When mixed with isocyanate or its adduct, a compound having an isocyanate group, it reacts further to form a polymer having a network structure. Isocyanate-modified polymers are characterized by high initial adhesive strength. The vapor deposited film 4 can be provided by vacuum vapor depositing a metal compound on the surface of the transparent plate according to the present invention. When a thin film of zinc sulfide, cryolite, silicon oxide, magnesium fluoride, aluminum oxide, etc. is deposited on the surface of a light-transmitting plate, the light-transmitting plate exhibits polarizing properties and can also be used as an anti-reflection film, an interference filter, etc. performance can be imparted.
