Inkjet recording method

1. An inkjet recording method comprising ejecting ink droplets on an image-receiving material according to recording signals to record an image on the image-receiving material, wherein at least one of the ink and the image-receiving material comprises an acid precursor capable of releasing an acid by a chemical reaction, wherein one of the acid precursor and a compound which reacts with the acid precursor to release an acid is contained in the ink, and another one of the acid precursor and the compound is contained in the image-receiving material, wherein the acid precursor is a compound comprising an atom which changes to a hard acid by the chemical reaction or an atomic group which changes to a hard acid by the chemical reaction, and the compound which reacts with the acid precursor to release an acid is a compound comprising a nucleophilic group.

2. The inkjet recording method according to claim 1 , wherein the compound which reacts with the acid precursor to release an acid is contained in the image-receiving material.

3. The inkjet recording method according to claim 2 , wherein the compound that reacts with the acid precursor to release an acid is contained in the image-receiving material in an amount of from 0.05 to 5 g/m 2 .

4. The inkjet recording method according to claim 1 , wherein at least the ink comprises an acid precursor.

5. The inkjet recording method according to claim 4 , wherein the ink comprises from 0.5 to 5% by weight of the acid precursor.

6. The inkjet recording method according to claim 1 , wherein the compound that reacts with the acid precursor to release an acid is contained in the ink.

7. The inkjet recording method according to claim 6 , wherein the compound that reacts with the acid precursor to release an acid is contained in the image-receiving material in an amount of from 0.05 to 5 g/m 2 .
