INK JET RECEIVING MATERIAL

摘要

PROBLEM TO BE SOLVED: To obtain a receiving material having photographic gloss and high transparency by forming an ink absorbing layer as a three-dimensionally crosslinked layer formed from an amphoteric water-soluble polymer containing both of an anionic monomer and a cationic monomer as constitutional units and an aziridine crosslinking agent. SOLUTION: In an ink jet receiving material wherein ink absorbing layer is provided on a support, the ink absorbing layer is formed as a three- dimensional crosslinked layer formed from at least one amphoteric water-soluble polymer containing both of an anionic monomer and a cationic monomer as constitutional units and an aziridine crosslinking agent reacting with the amphoteric water-soluble polymer. The amphoteric water-soluble polymer generates an ion bond between molecules and in molecules and film strength can be increased. Since anionic groups are reacted with the aziridine crosslinking agent to form a chemical bond, a polymer itself is made insoluble by three- idimensional crosslinking and water resistance can be provided to a film itself.
