摘要： A near-infrared absorptive liquid dispersion, which contains a near-infrared absorptive compound represented by formula (1) that is dispersed in a form of fine particles in a dispersing medium: wherein R 1a and R 1b may be the same or different, and each independently represent an alkyl group, an aryl group, or a heteroaryl group; R 2 and R 3 each independently represent a hydrogen atom or a substituent, and at least one of R 2 and R 3 is an electron withdrawing group; R 2 may be bonded to R 3 to form a ring; and R 4 represents a hydrogen atom, an alkyl group, an aryl group, a heteroaryl group, a substituted boron, or a metal atom, and R 4 may be covalently bonded or coordinately bonded to at least one among R 1a , R 1b and R 3 .
