摘要
PROBLEM TO BE SOLVED: To provide a method for finely dispersing a pigment capable of optimizing the quality of printing, and an inkjet recording body having an ink receiving layer formed by applying a finely dispersing liquid obtained by the method, and having a high printing density, being excellent in surface smoothness, the quality of printing and ink water resistance, being capable of outputting an image with a high resolution being equal to a silver salt photograph.;SOLUTION: The method for finely dispersing the inorganic particulate in the dispersion is characterized by finely dispersing the dispersion of the inorganic fine particle by facing and making the dispersion of the inorganic particulate collide at least at two or more sites in a flow path for the dispersion through an orifice with a minimum flow path area of ≥0.1 mm2 within a range of pressure 20-300 MPa.;COPYRIGHT: (C)2006,JPO&NCIPI
