INK FOR INKJET RECORDING, INK SET FOR INKJET RECORDING AND INKJET RECORDING METHOD

摘要

An object of the present invention is to provide a magenta ink for ink jet recording excellent in weathering resistance. An additional object of the present invention is to provide a magenta ink for ink jet recording which is preferably provided with a hue as magenta ink, exhibits a high stability in ejection and causes no defects in water resistance and image quality in addition to the aforesaid requirement. The objects of the present invention are accomplished with an ink for ink jet recording comprising a magenta dye selected from azo dyes dissolved or dispersed in an aqueous medium, characterized in that said magenta dye is a dye having a absorption maximum in a spectral range of from 500 to 580 nm in said aqueous medium and a more positive oxidation potential than 1.0 V (vs SCE), particularly with the aforesaid ink for ink jet recording wherein the azo dye has a specific structure having a 5-membered heterocyclic ring and a 4-amino-6-membered heterocyclic ring connected to the azo group.
