Abstract

Provided is a coloring composition with which a film capable of allowing transmission of infrared light in a state where noise generated from visible light is small can be formed. In addition, also provided are a film, a color filter, a pattern forming method, a method for manufacturing a color filter, a solid image pickup element, and an infrared sensor in which the coloring composition is used. The coloring composition includes a coloring material that shields light in a visible range; and an infrared absorber. It is preferable that the coloring material that shields light in the visible range includes two or more chromatic colorants and that a combination of the two or more chromatic colorants forms black. Alternatively, it is preferable that the coloring material that shields light in the visible range includes an organic black colorant. It is preferable that the organic black colorant is at least one selected from the group consisting of a perylene compound and a bisbenzofuranone compound.
