Embodiment 1

[0070] Embodiment 1 (above-mentioned compound example No.1)

[0071] Add 3.0 parts of phthalic anhydride, 11.9 parts of naphthalic anhydride, 29 parts of urea, 0.40 parts of ammonium molybdate and 3.5 parts of vanadyl (V) chloride to 120 parts of sulfolane, and raise the temperature of the resulting composition to 200°C , reacted at this temperature for 11 hours. After the reaction was terminated, the reaction liquid was cooled to 65° C., 100 parts of N,N-dimethylformamide (DMF) was added, and a solid was separated and separated by filtration. The obtained solid was washed with 50 parts of DMF to obtain 20.3 parts of a wet cake. The obtained wet cake was added to 100 parts of DMF, the obtained composition was heated up to 80 degreeC, and it stirred at this temperature for 2 hours. The precipitated solid was separated by filtration and washed with 200 parts of water to obtain 18.9 parts of a wet cake. The obtained wet cake was added to 150 parts of water, the obtained compos...

Embodiment 2

[0072] Embodiment 2 (above-mentioned compound example No.2)

[0073] Except changing 3.0 parts of phthalic anhydrides in Example 1 to 5.9 parts, and changing 11.9 parts of naphthalic anhydrides to 7.9 parts, it carried out similarly to Example 1, and obtained 12.1 parts of said compound example No. 2. The maximum absorption wavelengths of this compound in concentrated sulfuric acid are 951nm, 882nm and 815nm.

Embodiment 3

[0074] Embodiment 3 (above-mentioned compound example No.9)

[0075]Add 3.3 parts of 3,4-pyridinedicarboxylic acid, 7.9 parts of naphthalene dicarboxylic anhydride, 29 parts of urea, 0.40 parts of ammonium molybdate, and 3.5 parts of vanadyl (V) chloride to 120 parts of sulfolane, and raise the temperature of the resulting composition to 200° C., and reacted at this temperature for 11 hours. After the reaction was terminated, the reaction liquid was cooled to 65° C., 100 parts of N,N-dimethylformamide (DMF) was added, and a solid was separated and separated by filtration. The obtained solid was washed with 200 parts of 80° C. DMF to obtain 20.3 parts of a wet cake. The obtained wet cake was added to 100 parts of DMF, the obtained composition was heated up to 80 degreeC, and it stirred at this temperature for 2 hours. The precipitated solid was separated by filtration and washed with 200 parts of water to obtain 40.1 parts of a wet cake. The obtained wet cake was added to 15...

Abstract

A porphyrazine dye represented by formula (1), and a dye dispersing composition containing the same. [In formula (1): M represents a metal atom, a metal oxide, a metal hydroxide, a metal halide, or a hydrogen atom; rings A, B, C and D each independently represent formulas (2)-(8) (except where A, B, and C are all (8)); X represents a lower alkyl group, a lower alkoxy group, an amino group, a nitro group, a halogen group, a hydroxy group, a carboxy group, a sulfonic acid group, or a sulfonamide group; Y represents a divalent crosslinking group; Z represents a sulfonic acid group, a carboxy group, a residue from which at least one hydrogen above a nitrogen atom on a primary-secondary amino group has been removed, or a residue from which at least one hydrogen above a nitrogen atom in a heterocyclic ring containing nitrogen has been removed; a and b are each average values; a and b are each 0-12; and the sum of a and b is 0-12].

Description

technical field [0001] The present invention relates to a novel porphyrazine pigment that exhibits excellent absorption in a specific near-infrared region, high transmittance in a visible light region, and does not impair aesthetics, and its use. Background technique [0002] In recent years, it has been demanded to reduce the load on air-conditioning equipment from the viewpoint of energy saving, global environmental problems, and the like. For example, in the fields of housing and automobiles, there is a heat-ray-shielding glass with a heat-ray-shielding material that can shield heat rays from sunlight on the window glass, which has a suppressing effect on the temperature rise in the room and inside the car. As the heat ray shielding material, a near-infrared absorbing dye is used. [0003] When attaching this heat ray shielding material to the window glass of a house or an automobile, it is desirable to have a high visible light transmittance from the viewpoint of ensuri...
