20140132661 | INKJET RECORDING METHOD AND INK SET FOR INKJET RECORDING - Provided is an inkjet recording method which minimizes blur and achieves excellent fixing to a recoding medium. This inkjet recording method is characterized by adhering a receiving solution (A) to at least areas on a recording medium (R) which are to be printed with an inkjet ink (I) or the whole surface of the medium (R) which is to be printed, said receiving solution (A) being a solution obtained by dissolving (inclusive of dispersing) one or more metal salts (S) selected from among at least divalent, calcium salts, magnesium salts, nickel salts, aluminum salts, boron salts, and zinc salts and one or more resins (B) having hydrophilic groups in an aqueous solvent in such amounts that the concentrations of the metal salts (S) and the resins (B) fall within the range of 0.005 to 2.0 mol/l and within the range of 0.5 to 20 mass % respectively, and then applying the inkjet ink (I) to areas where the metal salts are present in an adhered state to carry out printing. Said inkjet ink (I) is an ink which comprises a pigment (P), an anionic resin emulsion (E), and an aqueous solvent, and in which phosphorus-containing groups each having at least one P—O or P═O bond are bonded to the surface of the pigment (P) or the surface of the anionic resin emulsion (E). | 05-15-2014 |
20140065367 | STRUCTURE HAVING SPECIFIC SURFACE SHAPE AND METHOD FOR MANUFACTURING SAID STRUCTURE - There is provided a structure having convex parts with an average height of 100 nm or more and 1000 nm or less, or concave parts with an average depth of 100 nm or more and 1000 nm or less on a surface thereof.

The structure is obtained by polymerizing a polymerizable composition containing a (meth)acrylate compound by light irradiation, electron beam irradiation and/or heating, the (meth)acrylate compound contains 53% by mass or more polyethylene glycol di(meth)acrylate based on the whole (meth)acrylate compound. The structure has a storage elastic modulus at 25° C. of 2 GPa or less and/or a storage elastic modulus at 180° C. of less than 0.5 GPa. | 03-06-2014 |
20140055520 | INKJET RECORDING METHOD - An inkjet recording method which suppresses feathering and color bleeding and is excellent in fixability to a recording medium. The inkjet recording method includes the steps of applying an ink-receiving solution prepared by dissolving in an aqueous solvent at least one metal salt having a water solubility of 0.1 mol/l or more, selected from calcium salts, magnesium salts, nickel salts and zinc salts having a valence of 2 or more, to at least the surface to be printed by using an inkjet ink or the entire surface of a recording medium; and printing on the metal salt adhered part by using the inkjet ink comprising at least a pigment, a resin emulsion and an aqueous solvent containing a surfactant. Further, a phosphorus-containing group having at least one P—O or P═O bond is bound to the surface of the pigment. | 02-27-2014 |
