Abstract

An ink characterized by containing at least one compound selected from phthalocyanine compounds represented by the general formulae (I), (II), (III) and (IV) has an absorption characteristic superior in color reproducibility as dyes of three primary colors and has sufficient fastness to light, heat, humidity, and active gases in an environment, and hence, can give colored images or colored materials having superior46. The ink can be used for various coloring compositions such as ink compositions for inkjet printing, ink sheets in thermal transfer image-forming materials, coloring compositions for color filters in electrophotographic toners, LCD, PDP, and CCD, and dyeing baths for dyeing various fibers.

Claims

1. An ink, which is characterized by containing at least one compound selected from phthalocyanine compounds represented by the following general formulae (I), (II), (III) and (IV):

2. The ink according to claim 1, wherein the compounds represented by the foregoing general formulae (I), (II), (III) and (IV) are compounds represented by the following general formulae (V), (VI), (VII) and (VIII), respectively:

3. The ink according to claim 1, wherein the compounds represented by the foregoing general formulae (I), (II), (III) and (IV) are compounds represented by the following general formulae (IX), (X), (VI) and (XII), respectively:

4. The ink according to claim 1, wherein the compounds represented by the foregoing (I) to (IV) is contained in an amount of 0.2 parts by weight or more and 10 parts by weight or less in 100 parts by weight of the ink.

5. The ink according to claim 2, wherein the compounds represented by the foregoing (V) to (VIII) is contained in an amount of 0.2 parts by weight or more and 10 parts by weight or less in 100 parts by weight of the ink.

6. The ink according to claim 3, wherein the compounds represented by the foregoing (IX) to (XII) is contained in an amount of 0.2 parts by weight or more and 10 parts by weight or less in 100 parts by weight of the ink.

7. The ink according to claim 1, which is an ink for ink-jet recording.

8. The ink according to claim 2, which is an ink for ink-jet recording.

9. The ink according to claim 3, which is an ink for ink-jet recording.

10. An inkjet recording method, which comprises forming images on an image-receiving material having an ink-receiving layer containing white inorganic pigment particles on a support by using the ink for inkjet recording according to claim 7.

11. An inkjet recording method, which comprises forming images on an image-receiving material having an ink-receiving layer containing white inorganic pigment particles on a support by using the ink for inkjet recording according to claim 8.

12. An inkjet recording method, which comprises forming images on an image-receiving material having an ink-receiving layer containing white inorganic pigment particles on a support by using the ink for inkjet recording according to claim 9.

13. A method of improving ozone gas resistance by forming images using the ink for inkjet recording according to claim 9, thereby improving an ozone gas resistance of a colored image material.

14. A phthalocyanine compound, which is represented by any of the foregoing general formulae (IX), (X) and (XI).
