Document Type and Number:
Japanese Patent JP6905317
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an oxocarbonic compound showing a plurality of absorption peaks in a range of a wavelength of 600 nm or more and 1,100 nm or less in a resin cured product and a resin composition containing the same, and to provide a light selective transmission filter capable of cutting light rays having a plurality of wavelength regions at a wavelength of 600 nm or more and 1,100 nm or less.SOLUTION: A resin composition contains an oxocarbonic compound and a resin, where an uncured product of the resin composition has an absorption peak X at a wavelength of 600 nm or more and less than 800 nm, and a cured product of the resin composition has an absorption peak Y at a wavelength of 600 nm or more and less than 800 nm and an absorption peak Z at a wavelength of 800 nm or more and 1,100 nm or less. A light selective transmission filter has a light absorption layer containing an oxocarbonic compound and a resin, where the light absorption layer has an absorption peak Y at a wavelength of 600 nm or more and less than 800 nm, and an absorption peak Z at a wavelength of 800 nm or more and 1,100 nm or less.SELECTED DRAWING: Figure 1
