<P>PROBLEM TO BE SOLVED: To provide an inkjet recording sheet of highly absorbency and chromogenic effect in ink. <P>SOLUTION: This inkjet recording sheet includes an ink receiving layer on at least one side of its base. The ink receiving layer mainly contains hydroxyapatite microparticles synthesized through two processes: the first process to synthesize tabular dicalcium phosphate dihydrate crystal, and the second process to make alkali treatment of the obtained dicalcium phosphate dihydrate crystal under the reactive condition of pH 12 or more and 50°C or more. <P>COPYRIGHT: (C)2013,JPO&INPIT |
