Embodiment 1

[0269] Dissolve cesium carbonate (Cs 2 CO 3 )7.43kg to obtain a solution. This solution was added to tungstic acid (H 2 WO 4 ) 34.57kg, after fully stirring and mixing, dry while stirring (corresponding to the molar ratio of W and Cs 1:0.33). One side is supplied with N 2 The gas is 5 volume % H of the carrier gas 2 While heating the dried product, it was fired at 800°C for 5.5 hours. Then, replace this supply gas with only N 2 gas, cooled to room temperature to obtain cesium tungsten oxide particles.

[0270] 20% by mass of cesium tungsten oxide particles, 75 parts by weight of toluene, and 5 parts by weight of polyacrylate polymer resin (hereinafter referred to as "resin a" in this embodiment and comparative examples) were mixed to prepare 30kg slurry. This slurry was added to a media agitation mill together with balls, and pulverization and dispersion treatment was performed for 10 hours. In addition, the media agitation mill used the horizontal cylindrical ring t...

Embodiment 2、3

[0282] Except that polyethylene resin or acrylic resin was used instead of polypropylene resin, the same procedure as in Example 1 was carried out to obtain the infrared-absorbing particle dispersions, powders in which infrared-absorbing particles were dispersed, and infrared-absorbing particles containing Fine particle masterbatch pulverization, anti-counterfeiting ink, printing film for anti-counterfeiting.

[0283] The same evaluation as in Example 1 was performed on the infrared-absorbing fine particle dispersion liquid, the masterbatch pulverized product containing infrared-absorbing fine particles, and the anti-counterfeiting printed film of Examples 2 and 3.

[0284] The manufacturing conditions and evaluation results are shown in Tables 1 and 2.

Embodiment 4

[0286] When pulverizing the masterbatch containing infrared-absorbing microparticles, a jet-grinding pulverizer was used instead of a hammer mill. In the same manner as in Example 1, the powder in which infrared-absorbing microparticles were dispersed in Example 4, containing Crushed masterbatch of infrared absorbing particles, anti-counterfeiting inks, printing films for anti-counterfeiting.

[0287] The same evaluation as in Example 1 was performed on the infrared-absorbing fine particle dispersion liquid, the masterbatch pulverized product containing infrared-absorbing fine particles, and the anti-counterfeiting printing film of Example 4.

[0288] The manufacturing conditions and evaluation results are shown in Tables 1 and 2.
