Abstract: PURPOSE:To obtain a plastic lens having good transparency and color tones and a high refractive index by using a specific crosslinked structure formable org. compd. as an essential component, adding a dye having a complementary color relation with the lens color tone to said compd. and polymerizing the same. CONSTITUTION:The dye having the complementary color relation with the color tone of the high refractive index plastic lens having >=1.50 refractive index nd and essentially consisting of the crosslinked structure formable org. compd. is added to the compsn. for producing said lens and the compsn. is polymerized. A radically polymerizable multifunctional org. vinyl monomer contg. an arom. ring is effective as the compd. having such high refractive index and crosslinked structure characteristic and further such vinyl monomer is more preferable if said monomer contains halogen elements except fluorine. A disperse die is preferable as the dye to be added to the compsn. for the purpose of improving the color tone and is preferably used at about 0.01-100ppm. The color tone of the plastic lens having the particularly high refractive index is thereby improved and the resulted lens has the stable color tone effect even if the lens is left standing under heating or UV rays such as outdoor exposure.

Abstract: PURPOSE:To obtain a high refractive index, satisfactory formability and heat resistance by using a resin contg. specified two kinds of monomers as essential components and having a three-dimensional structure. CONSTITUTION:A plastic lens is made of a resin contg. a monomer represented by formula I (where X is halogen other than F and m=1-5) and a monomer represented by formula II (where R is H or methyl, X is halogen other than F, Y is a group represented by formula III, m=3-5 and n=0-5) as essential components and having a three-dimensional structure. A residue of a multifunctional vinyl compound represented by formula IV (where each of R1 and R2 is H or methyl, X is halogen other than F, A is -SO4- or the like, m=0-2 and n=0-1) or formula V is preferably used as a compound having a three-dimensional structure in the resin. It is preferable that the resin is composed essentially of 20-85pts.wt. monomer represented by the formula I, 5-70pts.wt. monomer represented by the formula II and 10-60pts.wt. units having a three-dimensional cross-linkable structure. Since the monomers represented by the formulae I, II are used by large amounts, a lens having a high refractive index of >=1.63 is obtd. and the thickness of the peripheral part of the lens can be reduced. Since the multifunctional monomer is used, the degree of cross-linking is increased and superior heat and shock resistances and workability are provided.

Abstract: PURPOSE:To obtain the titled composition having long-period preservation stability and heat stability, not inhibiting initiator activity of polymerization initiator, free from problem of bad smell, by adding a specific polymerization initiator to a radically polymerizable polyfunctional vinyl monomer. CONSTITUTION:An aromatic ring-containing radically polymerizable polyfunctional vinyl monomer is blended with usually 0.01-1,000ppm N- nitrosophenylhydroxylamine salt compound shown by formula I (n is 1-4; X is metal or 1-4 valance or NH4). A di(meth)acrylate shown by formula II (R is H or CH3; X is Cl, Br or F; n is 0-4; m is 0-6; A is -SO2-, etc.) or an isocyanate modified monomer shown shown by formula III (R1 and R2 are CH3 or H; X is Cl, Br or F; Z is polyfunctional isocyanate residue; A is SO2; m and n are 0-4 and m+n=0-4; p is 0-4; q is 2 or 3) is preferable as the monomer.

Abstract: PURPOSE:To obtain an optically uniform plastic lens having an excellent appearance, by covering the outer circumference of a space held with a gasket and two glass molds with a heat insulating material at the time when a liquid curable compound is poured into the space. CONSTITUTION:Only an outer circumferential zone may be insulated on the upper face of the outer circumferential part formed with a gasket 2 and two glass molds 1, but the bottom face and side face parts are preferably wholely covered for heat insulation. By covering and heat-insulating it, a whole lens can be uniformly heated to obtain a lenz free of striae. As the heat insulating material, an asbestos foam or 4a polypropylene foam may be preferably used. The liquid curable compound to be poured has a refractive index of 1.50 or more and is an organic compound being formable into a crosslinked structure and containing 5 wt.% or more of a polyfunctional organic vinyl monomer containing an aromatic ring and being radically-polymerizable.

Abstract: PURPOSE:To form a plastic lens having high refractive index and >=35 Abbe's number and >=1.60 refractive index by constituting the lens of specified recurrent structural units as principal component. CONSTITUTION:A plastic lens is constituted of recurrent structural units expressed by the formula I as principal component. In the formula I, -CHmHnXp is a halogen-contg. aliphatic and/or halogen-contg. alicyclic group; R is H or methyl; X is a halogen atom except F; l is 1-3; m is 1-12; n+p is an integer 1-25. Since the plastic lens has >=1.60 refractive index, the thickness of the external periphery of the lens can be made thin. Further, since the lens has >=35 Abbe's number, the chromatic aberration of the lens is made smaller than the chromatic aberration of conventional lenses having high refractive index.

CONSTITUTION:A composition contg. repeating units represented by formula I (where X is halogen other then F and m=1-5), formula II (where R is H or methyl, X is halogen other than F, Y is a unit represented by formula III, 3=3-5 and n=0-2) and formula IV [where R is H or methyl and A is a group represented by formula V (where R is H or methyl and n=1-10)] as essential components is copolymerized, and the resulting resin having a three- dimensional cross-linked structure is used to obtain a three-dimensional cross- linked structure is used to obtain a plastic lens. The preferred amount of the repeating units represented by the formulae I, II, IV are 20-85pts.wt., 5-70pts. wt. and 20-60pts.wt., respectively. The plastic lens has >=1.60 refractive index and >=35 Abbe's number and also has superior casting work efficiency, heat and shock resistances. The thickness of the peripheral part of the lens can be reduced and the lens has small chromatic aberration and superior post- workability.
