The present invention provides a yellow ink composition suitable for inkjet recording, which has good printing quality and good colorant fixability to a recorded matter. The hue and ozone resistance of the yellow ink composition can be adjusted, while maintaining high light resistance. Also disclosed are an ink set and an ink cartridge each using the yellow ink composition, an inkjet recording method using them, and a recorded matter. Specifically disclosed is a yellow ink composition containing a compound represented by the formula (I) below and a compound represented by the formula (II) below as a colorant. [chemical formula 1] (I) (In the formula, X1, X2, Y1 and Y2 independently represent a hydrogen atom or a cyano group; Z1 and Z2 independently represent a substituent having an aromatic ring;R1 and R2 independently represent an alkyl group; and M represents a metal atom.) [chemical formula 2] (II) (In the formula, R represents a methoxy group or a methyl group; and A represents 1,5-disulfonaphtho-3-yl or 1,5,7-trisulfonaphtho-2-yl).
