Inkjet color ink

摘要

An inkjet color ink comprising: an aqueous medium; at least one yellow dye having a lambdamax of from 390 nm to 470 nm and an [I(lambdamax+70 nm)/I(lambdamax)] ratio of an absorbance I(lambdamax+70 nm) at lambdamax+70 nm to an absorbance I(lambdamax) at lambdamax of not more than 0.4; and at least one dye having a lambdamax of longer than 470 am and not longer than 750 nm, the at least one yellow dye and the at least one dye being at least dissolved or dispersed in the aqueous medium, wherein both of the rate constants defined herein are not more than 5.0x10<-2 >hour<-1>.
