Abstract

According to the present invention, a novel phthalocyanine compound having a specific structure is provided, and an ink, an inkjet recording ink, an inkjet recording method and a method for improving preservability of a formed image, each using the compound, are also provided.

The novel phthalocyanine compound of the present invention has a sufficiently high fastness to light, heat, humidity and active gases in the environment and by using an ink, particularly inkjet recording ink, containing the phthalocyanine compound, an image having high fastness to light and ozone gas in the environment can be formed.

Claims

1. An ink comprising at least one compound represented by the following formula (I) or (II):

2. The ink according to claim 1, wherein the compound represented by the formula (I) or (II) comprises at least one compound represented by the following formula (III) or (IV):

3. The ink according to claim 1, wherein the compound represented by the formula (I) or (II) comprises at least one compound represented by the following formula (V) or (IV):

4. The ink according to any one of claims 1 to 3, wherein a phthalocyanine compound represented by the formulae (I) to (VI) has at least two ionic hydrophilic groups selected from a carboxyl group, a sulfo group and a quaternary ammonium within one molecule.

5. The ink according to claim 4, wherein the ionic hydrophilic group is at least either a carboxyl group or a sulfo group.

6. The ink according to any one of claims 1 to 5, which is an inkjet recording ink.
