As dispersing agents,the effects of nonionic water-soluble surfactant such as Tween 80,OP-10,K30 and anionic water-soluble surfactant such as SN-6100 on performances of aqueous gel ink including stability,apparent viscosity,thixotropic value were studied for 24 mono surfactant formulations and 6 blend surfactant formulations.Results indicated that the stability of the aqueous gel ink as dispersing agents exclusively using SN-6100 or K30 is better than OP-10 or Tween 80,and when the ratio of SN-6100 to carbon black powder is 0.2,and the ratio of K30 to carbon black powder is 0.26,aqueous gel ink with good stability can be obtained.
