an infrared absorber;
a photopolymerization initiator; and
a curable compound,
wherein the photopolymerization initiator is at least one of an oxime compound or an α-aminoketone compound;
wherein the infrared absorber includes at least one compound selected from the group consisting of a phthalocyanine compound, a squarylium compound, a croconium compound, a diimmonium compound, a perylene compound, a pyrrolopyrrole compound, a metal complex, and a compound semiconductor; and
wherein an absorbance X of the infrared absorber at a maximum absorption wavelength in a wavelength range of 400 nm to 1,300 nm and a maximum absorbance Y in a wavelength range of longer than 950 nm and 1,300 nm or shorter satisfy Expression 1,
