Near-infrared absorptive dye-containing curable composition, ink composition and method of producing near-infrared absorptive filter

摘要

A curable composition, containing a near-infrared absorptive dye represented by formula (1):;wherein R1a and R1b may be the same or different, and each independently represent an alkyl group, an aryl group, or a heteroaryl group; R2 and R3 each independently represent a hydrogen atom or a substituent, and at least one of R2 and R3 is an electron withdrawing group; R2 and R3 may be bonded to each other to form a ring; and R4 represents a hydrogen atom, an alkyl group, an aryl group, a heteroaryl group, a substituted boron, or a metal atom, and R4 may be covalently bonded or coordinately bonded to at least one among R1a, R1b and R3.

1. A curable composition, comprising a polymerizable monomer, a polymerization initiator, and a near-infrared absorptive dye represented by formula (1): wherein R1a and R1b may be the same or different, and each independently represent an alkyl group, an aryl group, or a heteroaryl group, and when R1a and R1b represent an aryl or heteroaryl group, at least one of R1a and R1b has an alkoxy group whose alkyl moiety is a branched alkyl group; R2 and R3 each independently represent a hydrogen atom or a substituent, and at least one of R2 and R3 is an electron withdrawing group; R2 and R3 may be bonded to each other to form a ring; and R4 represents a hydrogen atom, an alkyl group, an aryl group, a heteroaryl group, a substituted boron, or a metal atom, and R4 may be covalently bonded or coordinately bonded to at least one among R1a, R1b and R3, wherein the polymerizable monomer is a (meth)acrylic monomer having three or more polymerizing groups.
