Abstract

PURPOSE:To obtain such a lens having absorption at both of 555nm and 507nm at which the relative luminous efficiencies are high by compounding and polymerizing diethylene glycol-bisallyl carbonate monomer, specified oil-soluble dye, and acrylate with a specified compounding ratio. CONSTITUTION:The lens for glasses is obtd. by cast polymn. of diethylene glycol-bisallyl carbonate monomer with using a radical polymn. initiator. In this case, an oil-soluble dye having absorption near 560nm visible range is used by 0.0001-2.0 pts.wt. to 100 pts.wt. of the diethylene glycol-bisallyl carbonate monomer. Further, acrylate (methacryl) expressed by formula I is added by 2-30 pts.wt. to increase the solubility between the dye and the diethylene glycol- bisallyl carbonate monomer, and then casting copolymn. is effected. In formula, X is H or CH3 and R is an aliphatic alkyl group of 1-8 carbon number.

2. Description of the Related Art Originally, the purpose of eyeglass lenses is to correct visual acuity, but in addition to this, the effect of protecting the eyes from ultraviolet rays and strong light is also required. A glass lens can be used as an example of a spectacle lens for preventing the dazzling of strong sun rays and light of automobiles. This is a spectacle glass characterized by adding Nd 2 O 2 to a silicate or borosilicate glass or using Er 2 O 2 . (Japanese Patent Publication No. 48-8723,

However, it is the current situation that plastic lenses cannot easily and uniformly introduce Nd 2 O 2 or the like. Therefore, it has been desired to develop a plastic lens having an antiglare property similar to that of the glass lens. The most desirable anti-glare effect is the absorption of 555 nm, which shows the maximum relative luminous efficiency of the normal naked eye that adapts to bright outdoor conditions, and 507 nm, which indicates the maximum luminous efficiency that adapts to dark indoor conditions.

The present invention was obtained as a result of repeated studies for obtaining such a plastic spectacle lens. That is, 56 of oil-soluble dyes in diethylene glycol bisallyl carbonate resin monomer
A dye having an absorption in the visible region up to about 0 nm and an aliphatic acrylic ester for compatibilizing the dye with diethylene glycol bisallyl carbonate monomer are mixed by casting copolymerization to absorb in the wavelength region.

The present invention will be described in detail below. Plastic lenses made of diethylene glycol bisallyl carbonate resin are the most prevalent plastic eyeglass lenses at present. The allyl group, which is a polymerizable functional group of this monomer, has a lower radical polymerization activity than the methacryl group and the like, so that the polymerization initiator for carrying out the casting polymerization is limited and the peroxydicarbonate-based polymerization initiator is limited. Is used. However, this polymerization initiator has high activity,
Organic dyes usually decompose relatively early in the polymerization under this initiator. In this sense, it is difficult to obtain a dye suitable for the antiglare property which is the object of the present invention, and an effective diethylene glycol bisallyl carbonate-based antiglare lens cannot be obtained.

The present invention is a dye resistant to a peroxydicarbonate type polymerization initiator, has absorption having an antiglare effect, and has diethylene glycol bisallyl carbonate.
We searched for a method to make it compatible with resin.

However, these oil-soluble dyes have poor compatibility (solubility) with diethylene glycol bisallyl carbonate monomer and cannot improve antiglare properties. Therefore, in the present invention, an acrylic (methacrylic) ester represented by the following chemical structural formula (1) is used in order to improve the compatibility between this dye and diethylene glycol bisallyl carbonate monomer.

The reason why R is up to C 8 is related to the amount of acrylic (methacrylic) ester added when C exceeds 8 , but the copolymerizability with diethylene glycol bisallyl carbonate decreases. In addition, the copolymer resin becomes soft and the heat resistance decreases, and in the present invention, the size of R is up to C 8 .

The antiglare spectacle lens can be manufactured by a similar method except that the monomer is a mixture in the usual manufacturing process of the spectacle lens made of diethylene glycol bisallyl carbonate. That is, diethylene glycol bisallyl carbonate, an oil-soluble dye and an acrylic (methacrylic) ester are mixed within the scope of the present invention to form a monomer. 2-3 parts by weight of a peroxydicarbonate-based polymerization initiator was added to this, and the mixture was thoroughly stirred and degassed in vacuum. The desired antiglare spectacle lens can be obtained by injecting it into the mold and raising the temperature in the oven.
