Near-infrared absorbing film composition

An object of the present invention is to provide a near-infrared absorbing film composition. A (i) one or more near-infrared-absorbing polymethine dyes, (ii) one or more crosslinkable polymers, and (iii) comprises one or more casting solvent, curability It provides compositions. The present invention further near infrared absorbing film of a solid comprising a crosslinked form of the curable composition is also of interest. The present invention further relates to a case where a microelectronic substrate comprising a coating of the near infrared absorbing film of the solid, and the near-infrared absorbing film is between the microelectronic substrate and the photoresist film, coated on a microelectronic substrate method of patterning a photoresist layer also of interest. .FIELD 1
