<P>PROBLEM TO BE SOLVED: To provide an aqueous ink set for inkjet recording which, even when an aqueous ink containing an acid dye is mixed with another aqueous ink containing a basic dye, does not cause clogging at a head delivery part by depositing to enable to jet stably. <P>SOLUTION: The aqueous ink set for inkjet recording comprises the aqueous ink containing the acid dye and the aqueous ink containing the basic dye. The aqueous ink has an average molecular weight of 3,000-20,000 and comprises a polymer represented by formula (1) [wherein X is H or COONa; Y is H, COONa, SO<SB>3</SB>Na, or CH<SB>2</SB>OR, (wherein R is a 1-5C substituent group having SO<SB>3</SB>Na), when the ink containing the acid dye is mixed with the ink containing the basic dye, clogging at the head delivery part is prevented to allow to jet stably]. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
