| abstract |
The present invention relates to a near infrared ray absorbing composition, a curable composition, a cured film, a near-infrared ray cut filter, a solid-state image sensor, an infrared sensor, a camera module, a process dye, and a method for producing a processed dye, which have high dispersibility of a near infrared ray absorbing dye and are small in thixotropy. to provide. The near infrared ray absorbing composition of the present invention comprises a processed pigment obtained by coating a near infrared ray absorbing dye with a resin having at least one selected from a dye structure, a heterocyclic structure and an acyclic hetero atom-containing group. Wherein the near infrared absorbing dye is selected from phthalocyanine dyes, perylene dyes, pyrrolopyrrole dyes, cyanine dyes, dithiol metal complex dyes, naphthoquinone dyes, dyimonium dyes, azo dyes and squarylium dyes More preferably one or more, and more preferably a pyrrolopyrrole dye. |
