Abstract: Provided is a near-infrared ray absorbing article. A near-infrared ray absorbing article of the present invention is capable of preventing a decrease in visible transmittance and near-infrared absorption due to the interaction between a plurality of organic materials forming light-absorbing layers. In addition, the near-infrared ray absorbing article of the present invention has the advantage of being able to be thinner. In addition, the near-infrared ray absorbing article of the present invention has the advantage of excellent mechanical properties such as strength and heat resistance
