The present invention provides an ink composition comprising at least water; at least one member selected from compounds represented by the following formula (1) and/or salts thereof; and at least one member selected from carboxyl group-containing aromatic compounds and/or salts thereof:
1
wherein A represents an alkylene group, a phenylene group-containing alkylene group or
2
(R means hydrogen or alkyl)
and X represents NH
2
, OH or Cl.
The present invention provides a method of forming an inkjet image, the method comprising: providing an inkjet recording ink comprising a colorless water-soluble planar compound having ten or more delocalized pi-electrons in one molecule; impacting a first droplet of the inkjet recording ink on a surface of an image receiving material; impacting a second droplet of the inkjet recording ink, within 50 milliseconds after the first droplet on the recording ink impacts on the surface of the image receiving material, on a surface of the image receiving material at a location where the second and the first droplet contact each other.

An efficient method for synthesis of anthranilic acids by Pd-catalyzed ortho-CâH amidation of benzoic acids is disclosed. The amidation is proposed to proceed by carboxylate-assisted ortho-CâH palladation to form an arylpalladium(II) complex, followed by nitrene insertion to the PdâC bond.
