Abstract
Official abstract text for this publication.
A curable composition includes: a near infrared absorbing colorant; a polymerizable compound; and a photopolymerization initiator, in which the near infrared absorbing colorant is a compound that includes a π-conjugated plane having a monocyclic or fused aromatic ring, and the photopolymerization initiator does not substantially include a compound having an oxime structure.
First claim
Opening claim text (preview).
What is claimed is: 1 . A curable composition comprising: a near infrared absorbing colorant; a polymerizable compound; and a photopolymerization initiator, wherein the near infrared absorbing colorant is a compound that includes a π-conjugated plane having a monocyclic or fused aromatic ring, a content of the near infrared absorbing colorant is 3 mass % or higher with respect to a total solid content of the curable composition, and the photopolymerization initiator does not substantially include a compound having an oxime structure. 2 . The curable composition according to claim 1 , wherein the photopolymerization initiator includes at least one selected from an alkylphenone compound, an acylphosphine oxide compound, a biimidazole compound, or a triazine compound. 3 . The curable composition according to claim 2 , wherein the photopolymerization initiator includes at least one selected from an alkylphenone compound or an acylphosphine oxide compound. 4 . The curable composition according to claim 1 , wherein the near infrared absorbing colorant includes at least one selected from a pyrrolopyrrole compound, a cyanine compound, or a squarylium compound. 5 . The curable composition according to claim 1 , wherein the near infrared absorbing colorant includes at least two compounds having different maximum absorption wavelengths. 6 . The curable composition according to claim 2 , wherein the near infrared absorbing colorant includes at least two compounds having different maximum absorption wavelengths. 7 . The curable composition according to claim 4 , wherein the near infrared absorbing colorant includes at least two compounds having different maximum absorption wavelengths. 8 . A cured film which is formed using the curable composition according to claim 1 . 9 . A near infrared cut filter comprising: the cured film according to claim 8 . 10 . A solid image pickup element comprising: the cured film according to claim 8 . 11 . An image display device comprising: the cured film according to claim 8 . 12 . An infrared sensor comprising: the cured film according to claim 8 .
