RECORDING FLUID AND RECORDING METHOD USING THE SAME

摘要

Disclosed is a recording liquid essentially composed of water, a coloring material, an organic solvent and a surfactant. The surfactant is composed of a specified ethylene oxide/ propylene oxide/ ethylene oxide block copolymer, a specified ethylene oxide/ butylene oxide/ ethylene oxide block copolymer or a specified propylene oxide/ ethylene oxide/ propylene oxide block copolymer. The recording liquid is superior in ejection stability and high in optical density even on multi-color recording letters/ characters or images on an ordinary paper sheet so that it allows for high quality recording free of boundary bleeding or all-over color unevennesses otherwise caused by color mixing.
