The present invention provides black ink compositions for use in inkjet printing, which exhibit improved neutral color, light fastness, and gray scale properties. The black ink compositions generally include a mixture of two or more black dyes in balanced concentrations to obtain black ink having the improved properties while retaining good print-ability in an inkjet pen. In one aspect, a black ink composition may include a mixture of pacified Reactive Black 31 and Direct Black 168. |
