Inkjet recording method
View Patent ↗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.
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 the ink comprises an acid precursor capable of releasing an acid by a chemical reaction, wherein the ink is a colorless ink that does not contain a coloring agent and has substantially no absorption in a visible light region, and 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 another ink.
2. The inkjet recording method according to claim 1 , 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.
3. 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 the ink is a colorless ink that does not contain a coloring agent and has substantially no absorption in a visible light region, and wherein at least one member selected from the group consisting of the acid precursor and a plurality of compounds that react with the acid precursor to release an acid is contained in the ink, at least one other member selected from the group is contained in another ink, and at least one still other member selected from the group is contained in the image-receiving material.
4. The inkjet recording method according to claim 3 , 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.
