Abstract
A near-infrared ray shielding paint capable of forming a coating that exhibits high light transmission coefficient in visible light region while having high shielding capability in near-infrared region and exhibits little chromaticity change even in harsh environment, which near-infrared ray shielding paint comprises a first near-infrared ray-absorption coloring matter containing a compound composed of a diimonium compound cation and an anion of the formula (1), a second near-infrared ray-absorbing coloring matter of different type and a transparent resin in which a compound of the formula (2) is polymerized in an amount of 30% by mass or more. A near-infrared ray shielding laminate having a near-infrared ray shielding layer is produced with the use of this paint.(CFSO)N  (1)
