- NEAR-INFRARED ABSORPTIVE COLORING MATTER AND NEAR-INFRARED ABSORPTIVE COMPOSITION
-
An object of the present invention is to provide a near infrared absorbent dye capable of providing a near infrared shielding filter with excellent transparency as well as high heat resistance and hygrothermal resistance. The near infrared absorbent dye is characterized in that it is made of the amorphous form of diimmonium salt represented by formula (1).

- NEAR-INFRARED ABSORBING FILM COMPOSITIONS
-
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.
