Abstract: Provided are an image recorded material including a substrate and an image recorded on the substrate, in which the image includes a cholesteric liquid crystal layer, the cholesteric liquid crystal layer has a stripe pattern of a bright portion and a dark portion, observed by a scanning electron microscope, in a cross section along a thickness direction of the image, in a case where an angle between a continuous line which is the bright portion or the dark portion and a main surface of the substrate is defined as an alignment angle, at least two regions in which an absolute value of a difference of the alignment angles is 5° or more are provided, and both of the two regions have a length of width of 1 mm or more in an in-plane direction of the substrate; and applications thereof.

Abstract: A display control device controls a display screen for displaying a preview of a print image to be printed on a recording medium by using an ink. The print image is printed using, as the ink, a structural color ink, and a color of the print image changes depending on a background. The display control device includes: a processor. The processor is configured to display, on the display screen, a preview image which is subjected to color conversion processing corresponding to the structural color ink, the preview image having the print image and the background superimposed.

Abstract: A display control device controls a display screen for displaying a preview of a print image to be printed on a recording medium by using an ink. The print image is printed using, as the ink, a structural color ink of which a color changes due to an optical phenomenon caused by a structure, and a color of the print image changes depending on an angle of visual recognition. The display control device includes: a processor. In a case where the print image is visually recognized at different angles, the processor is configured to display, on the display screen, a plurality of preview images corresponding to the angles by performing color conversion processing corresponding to the structural color ink.

Abstract: A color management apparatus includes at least one processor. The processor performs conversion between a first signal value and a first chromaticity value through a color profile. The color profile is created using a second chromaticity value of a color chart formed of at least one ink composition containing a liquid crystal compound and a chiral compound, and a second signal value. Each of the second chromaticity value and the second signal value is associated with amounts of the liquid crystal compound and the chiral compound.

Abstract: Provided are a decorative film including a base material and a reflective layer having a convex structure, in which, in a cross section obtained by cutting the convex structure in a direction perpendicular to a plane direction of the decorative film, in a case where a direction in which an average ?AVE of positive tilt angles is a largest is defined as a first direction and a direction in which the average ?AVE of the positive tilt angles is a smallest is defined as a second direction, the decorative film has a region A in which ?AVE in the first direction is 3° or more and ?AVE in the second direction is less than 3°; and applications thereof.

Abstract: There are provided a blood examination kit with which the procedure carried out by an examination subject is simplified and a method of separating plasma or serum.

Abstract: A steel tube for an airbag which has a low alloy cost and a strength of at least 1000 MPa and vTrs100 of ?80° C. or below and a process for its manufacture which can minimize the number of times that softening annealing treatment is performed in a cold drawing step are provided. Stable properties are obtained even when quench hardening is carried out by high frequency induction heating on a large scale. The steel tube has a steel composition which comprises, in mass percent, C: 0.05-0.20%, Si: 0.10-0.50%, Mn: 0.10-1.00%, P: at most 0.025%, S: at most 0.005%, Al: 0.005-0.10%, Ca: 0.0005-0.0050%, Nb: 0.005-0.050%, Ti: 0.005-0.050%, Cu: 0.01-0.50%, Ni: 0.01-0.50%, Cr: 0.01-0.50%, B: 0.0005-0.0050%, N: 0.002-0.010%, and a remainder of Fe and unavoidable impurities.

Abstract: A seamless steel tube for air bag use is formed from a steel comprising, in mass percent, C: 0.04-0.20%, Si: 0.10-0.50%, Mn: 0.10-1.00%, P: at most 0.025%, S: at most 0.005%, Al: at most 0.10%, Cr: 0.01-0.50%, Cu: 0.01-0.50%, Ni: 0.01-0.50%, a remainder of Fe and unavoidable impurities. The tube is cold drawn at least one time with a working ratio so that reduction in area is greater than 40% to obtain predetermined dimensions. The tube is then quench hardened by heating to at least the Ac3 point at a temperature rate increase of at least 50° C. per second followed by cooling at a cooling rate of at least 50° C. per second at least in a temperature range of 850-500° C. Tempering is done at a temperature of at most the Ac1 point.
