Document Type and Number:
WIPO Patent Application WO/2008/053776
Kind Code:
A1
Abstract:
The invention relates to water-soluble azo compounds represented by the general
formula (1) or salts thereof and ink compositions containing the same:
(1) (wherein R is hydrogen, alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon
atoms, or sulfo; n is 1 or 2; m is an integer of 1 to 3; x is an integer of 2 to 4; and y is
an integer of 1 to 3). The compounds or salts have high-clarity hues favorable
to ink-jet recording and can give prints having high fastnesses. Further, the
compounds are useful as yellow dyestuff capable of forming ink compositions
excellent in storage stability and therefore suitable for ink compositions,
particularly those for ink-jet recording.
