ABSTRACT:
The present invention provides an ink composition for ink jet recording, including an azo dye, a humectant, water, and an amino-group-containing water-soluble compound that undergoes condensation polymerization in the absence of the water (e.g., an aminosilane compound), wherein a straight-chain or branched alkyl group whose carbon number is two or more, an alkoxyl group, a phenyl group or a derivative group thereof, a phenoxyl group, or a six-membered or larger cycloalkyl group is introduced to a carbon atom at an α-position of the amino group in the amino-group-containing water-soluble compound that undergoes condensation polymerization in the absence of water.
