Publication number: 20240003787Abstract: The method of staining a biological sample includes: a first liquid application step of applying a first liquid onto one of a biological sample or a substrate on which the biological sample is placed, the first liquid containing a water-repellent component and being aqueous; a second liquid application step of applying a second liquid onto one of the biological sample or the substrate, the second liquid containing a thickening component and being aqueous; and a staining solution application step of applying a staining solution for staining the biological sample. The first liquid and the second liquid are applied so as to overlap each other at least partially, to thereby produce a mixed liquid. The first liquid application step and the second liquid application step include applying the first liquid and the second liquid so that the mixed liquid surrounds a region for holding the staining solution.Type: ApplicationFiled: June 27, 2023Publication date: January 4, 2024Inventors: AKIKO TOMINAGA, TOSHIKAZU ONISHI, MAMIKO KAJI, YOSHIYUKI KANEKO

Patent number: 10870770Abstract: An aqueous ink that enables recording of an image with suppressed feathering and has high ejection stability can be provided. An aqueous ink for ink jet contains a pigment, a polyhydric alcohol derivative and a water-soluble organic solvent. The polyhydric alcohol derivative is a compound in which a proportion of {Y/(X+Y)}×100 (%) where X mole(s) of ethylene oxide group(s) and Y mole(s) of propylene oxide group(s) are added to polyhydric alcohol having three or more hydroxy groups is 55% or more to 95% or less. The water-soluble organic solvent includes a first water-soluble organic solvent having a relative dielectric constant of 10.0 or more to 40.0 or less.Type: GrantFiled: July 5, 2018Date of Patent: December 22, 2020Assignee: Canon Kabushiki KaishaInventors: Junichi Sakai, Tsuyoshi Kanke, Akiko Tominaga, Mamiko Kaji, Takashi Imai

Patent number: 10525754Abstract: Provided is an ink jet recording method for recording an image on a recording medium by making use of an aqueous reaction liquid containing a reactant and first and second inks which are aqueous inks containing a coloring material. This method has a step of applying the reaction liquid to a first recording medium, a step of applying the first and second inks, in order of mention, to the first recording medium to form a first image and a step of bringing a porous layer of a liquid absorption member into contact with the first image and thereby absorbing a liquid component therefrom. The second image has brightness higher than that of the first ink.Type: GrantFiled: June 29, 2018Date of Patent: January 7, 2020Assignee: Canon Kabushiki KaishaInventors: Akiko Tominaga, Tsuyoshi Kanke, Satoshi Takebayashi, Junichi Sakai
