20080306222 | SURFACE TREATMENT SOLUTION WITH POLYMER MATERIAL, METHOD FOR PRODUCING SURFACE TREATMENT SOLUTION, LIQUID-CONTACTING SURFACE STRUCTURE, AND SURFACE TREATMENT METHOD USING LIQUID-PHASE POLYMER - A surface reforming method capable of efficiently carrying out a sustainable, even reforming treatment on a prescribed surface part of an element, a surface treatment liquid to be employed for the above-described method, and an element having a reformed surface treated by the above-described method. A part of the surface of an element is subjected to the reforming treatment by providing the object surface with a polymer, which is different from a constituent material of the object surface and comprises a first part having a functional group and a second part having an interfacial energy different from that of the functional group and approximately equal to the surface energy of the object surface and orienting the second part of the polymer toward the object surface and orienting the first part in a direction different from the object surface. | 12-11-2008 |
20090231388 | WASTE INK ABSORBENT MEMBER, AND WASTE INK CONTAINER AND INK JET RECORDING APPARATUS EQUIPPED WITH WASTE INK ABSORBENT MEMBER - To provide a waste ink absorbing tank, capable, even in the case of utilizing an ink of a high coagulating property, of causing a waste ink absorbent member to efficiently absorb such ink. A waste ink absorbent member has a hole portion corresponding to an introducing position of the waste ink, and the hole portion is opened on a lateral face of the absorbent member. The waste ink, introduced into the hole portion moves in one direction toward the waste ink absorbent member and absorbed therein. | 09-17-2009 |
20100075046 | AQUEOUS INK, AQUEOUS INK SET, INK CARTRIDGE, INK-JET RECORDING APPARATUS, INK-JET RECORDING METHOD, AND IMAGE-FORMING METHOD - An aqueous ink comprises water, a water-insoluble coloring material, and plurality of water-soluble organic solvents and the plurality of water-soluble organic solvents including a good medium or good mediums for the water-insoluble coloring material and a poor medium or poor mediums for the water-insoluble coloring material. The ratio of the content of the poor medium and the content of the good medium is in a specific range. A water-soluble organic solvent showing the maximum Ka value out of respective Ka values of the plurality of water-soluble organic solvents is the poor medium. When the aqueous ink is in contact with a specific reaction liquid, the dissolution state or dispersed state of the water-insoluble coloring material in the ink is made unstable. As a result, an image which has a sufficiently large area factor even with a small amount of ink droplets and is excellent in image density, bleeding resistance, and fixability can be obtained. In addition, the aqueous ink is excellent in storage stability. | 03-25-2010 |
20100101680 | METHOD FOR LOADING LIQUID, LIQUID CONTAINER AND HEAD CARTRIDGE - A liquid loading method, a liquid container and a head cartridge are provided, which allow the liquid container to be appropriately loaded with liquid such that a stirring member provided in the liquid container fully fulfills its function. For this end, an infusion needle is inserted from the outside of the ink cartridge into the ink storage chamber comprising a swinging member for stirring ink, so that the ink is loaded into the ink storage chamber through the infusion needle. | 04-29-2010 |
20100183828 | PIGMENT DISPERSION AND INKJET RECORDING MEDIUM USING THE SAME - The present invention relates to a pigment dispersion having an inorganic pigment dispersed therein, characterized in that a metal compound adheres to the inorganic pigment and a metal ion concentration of the metal compound in the pigment dispersion does not exceed 0.05 mol/L. | 07-22-2010 |
20110059298 | SURFACE-MODIFIED INORGANIC PIGMENT, COLORED SURFACE-MODIFIED INORGANIC PIGMENT, RECORDING MEDIUM AND PRODUCTION PROCESSES THEREOF, AND IMAGE FORMING METHOD AND RECORDED IMAGE - The invention relates to a surface-treated inorganic pigment which has an inorganic pigment having acid function and an amorphous body located on the surface of the inorganic pigment having acid function and formed by at least a divalent or higher-valent metal and an anion component in a state where the inorganic pigment and the amorphous body do not chemically bond to each other, and which does not exhibit acid function. | 03-10-2011 |
20120218345 | WASTE INK ABSORBENT MEMBER, AND WASTE INK CONTAINER AND INK JET RECORDING APPARATUS EQUIPPED WITH WASTE INK ABSORBENT MEMBER - To provide a waste ink absorbing tank, capable, even in the case of utilizing an ink of a high coagulating property, of causing a waste ink absorbent member to efficiently absorb such ink. A waste ink absorbent member has a hole portion corresponding to an introducing position of the waste ink, and the hole portion is opened on a lateral face of the absorbent member. The waste ink, introduced into the hole portion moves in one direction toward the waste ink absorbent member and absorbed therein. | 08-30-2012 |
