Abstract:
Provided is a composition with which a film having excellent temporal stability and excellent adhesiveness with a support or the like can be formed. In addition, provided are a film, a near infrared cut filter, a solid image pickup element, an image display device, and an infrared sensor. The composition includes: a near infrared absorbing compound that includes a π-conjugated plane having a monocyclic or fused aromatic ring; and a compound A having a weight-average molecular weight of 3000 or higher that has a radically polymerizable ethylenically unsaturated group, in which the compound A includes a repeating unit having a graft chain.
