Abstract: A curable liquid formulation containing at least (i) one or more near-infrared absorbing triphenylamine -based dyes, and (ii) one or more casting solvents. The invention is also directed to solid near- infrared absorbing films composed of crosslinked forms of the curable liquid formulation. The invention is also directed to a microelectronic substrate containing a coating of the solid near-infrared absorbing film as well as a method for patterning a photoresist layer coated on a microelectronic substrate in the case where the near-infrared absorbing film is between the microelectronic substrate and a photoresist film.
