Nonaqueous inkjet ink and printed material of same Author篤美 白井 佐々木 寛 Year2021 SourcePatent application LanguageJapanese 2813LRXLUMiReader X-RayOne embodiment of the present invention relates to a nonaqueous inkjet ink which contains (A) an organic solvent 18 more (B) scale-like metal particles and (C) an additive for surface tension regulationwherein: the organic solvent (A) contains (a1-1) an alkylene glycol monoalkyl ether solvent represented by general formula 1 in an amount of from 10% by mass to 75% by mass relative to the total amount of the organic solvent (A); the scale-like metal particles (B) have an average thickness (t) of from 1 nm to 50 nm; and the content of the scale-like metal particles (B) relative to the total amount of the nonaqueous inkjet ink is from 0.1% by mass to 5% by mass.The settling distance can be measured usingfor examplea separation characteristic analyzer (LUMiReader X-Ray manufactured by MS Scientific Co.Ltd.). Specifically2 mL of well-mixed ink is encapsulated in a sample cell (a rectangular parallelepiped with internal dimensions of 10 mm in length × 10 mm in width × 80 mm in height)and the horizontal X-ray transmittance of the sample cell is measured immediately after encapsulation. To do. Nexta graph is created in which the measurement results are plottedwith the horizontal axis representing the measurement position of the sample cell (height of the sample cell (mm)) and the vertical axis representing the X-ray transmittance (%) at the measurement position. The X-ray transmittance is low on the bottom surface side of the sample cell (the height of the sample cell is 0 mm)and is high on the opening side of the sample cell (the height of the sample cell is 20 mm). When observing the change in X-ray transmittance from the bottom surface side to the opening side of the sample cellthe "position (height) A of the sample cell" when the X-ray transmittance changes by 10% / mm or more is set.The upper end (that isthe interface between the suspension phase and the supernatant phase) where the scaly metal particles (B) in the ink are present. In the graphthe position (height) of the sample cell at the point where the X-ray transmittance starts to change by 10% / mm or more can be defined as the “position (height) A of the sample cell”. Then24 hours laterthe same measurement is performed to obtain the "position (height) B of the sample cell". The distance at which the position of the upper end changes during 24 hours is defined as the settling distance (settling distance (mm / day) = A (mm) -B (mm)).

Physicochemical properties of MCS and MPS both containing ACN (MCS-ACN and MPS-ACN) are compared using native cassava and potato starchesas well as modified cassava and potato starches without ACNs. ACNs are trapped into the modified starches and the trapping efficiency value oscillates between 9.89% and 12.37%. The resulting MCS-ACN and MPS-ACN- powders display bimodal distributions with particle size lower than 900 nm and amorphous structure. Furthermorethe MCS-ACN and MPS-ACN powders show red color typical of ACNs and they are completely soluble in water and acidified water solutions at room temperature.
