Document Type and Number:
WIPO Patent Application WO/2017/047685
Kind Code:
A1
Abstract:
This polymerizable composition for an optical material contains an episulfide compound (A), an organic dye (B), a UV absorber (C), and a polymerization catalyst (D), the organic dye (B) having a main absorption peak (P) between 565 nm and 605 nm in a visible-light absorption spectrum measured in a chloroform or toluene solution of the organic dye (B), the absorption coefficient (mL/g∙cm) of the peak apex (Pmax) indicating the maximum absorption coefficient of the peak (P) being 0.5×105 or greater, the peak width at an absorbance 1/4 the absorbance of the peak apex (Pmax) of the peak (P) being in a range of 50 nm or less, the peak width at an absorbance 1/2 the absorbance of the peak apex (Pmax) of the peak (P) being in a range of 30 nm or less, and the peak width at an absorbance 2/3 the absorbance of the peak apex (Pmax) of the peak (P) being in a range of 20 nm or less.
