Document Type and Number:
WIPO Patent Application WO/2018/021567
Kind Code:
A1
Abstract:
Provided are a resin composition having a fine slightly-bluish color tone, an eyeglass lens including a base material comprising the resin composition, and a method for producing the resin composition. This resin composition is obtained by polymerization of a polymerizable composition containing a polyisocyanate compound and a polythiol compound, wherein the polymerizable composition contains a dye L having a maximum absorption wavelength within the range of 550-600 nm in a 20-ppm-by-mass toluene solution, and a dye S having a maximum absorption wavelength within the range of not less than 500 nm but less than 550 nm in a 20-ppm-by-mass toluene solution, and the mass ratio of the dye L to the dye S (mass of dye L / mass of dye S) is 5-500.
