|1. (WO2018180482) INFRARED LIGHT TRANSMITTING COMPOSITION|
|Applicants:||DNP FINE CHEMICALS CO., LTD.
|Title:||INFRARED LIGHT TRANSMITTING COMPOSITION|
The present invention addresses the problem of providing an infrared light transmitting composition which has improved transmittance for the near-infrared region, while transmitting almost no light in the visible light region. The problem is solved by an infrared light transmitting composition which contains a colorant, a dispersant and a solvent, and which is characterized in that: at least a red colorant, a blue colorant and a yellow colorant are contained as the colorant; and the dispersant contains a constituent unit that is represented by general formula (1). (In general formula (1), R1 represents a hydrogen atom or a methyl group; A represents a divalent linking group; each of R2 and R3 independently represents a hydrogen atom or a hydrocarbon group which may contain a heteroatom; and R2 and R3 may combine with each other to form a ring structure.)
