| 摘要 |
A polymeric particulate material suitable for use in an ink-jet receiver is prepared by generating an emulsion comprising a first phase having a first carrier fluid and a second phase having a second carrier fluid, said first and second carrier fluids being immiscible; carrying out a first treatment to at least one component of the first phase to form and/or maintain a skeletal structure of the treated at least one component of the first phase; carrying out a second treatment to the second phase to substantially remove the carrier fluid thereby generating a large capacity porous structure defined by the skeletal structure; and mechanically dividing (e.g. milling) the skeletal structure. A coating of the particles is capable of rapid uptake of large quantities of ink, especially when formed using a high internal phase water-in-oil emulsion.
