Aqueous fluid sets for inkjet printing methods

1. An aqueous particle-free fluid having a dynamic viscosity of less than or equal to 5 centipoise (5 mPa-sec) at 25° C., and comprising:

(b) a composition consisting of one or more compounds represented by the following structure (I):

HO—CH 2 —CH 2 —R   (I)

wherein R is a substituted or unsubstituted phenyl group or a substituted or unsubstituted phenoxy group, in a total amount of at least 0.5 weight % and up to and including 2 weight %; and

a solvo-surfactant in an amount of at least 0.1 weight % and up to and including 20 weight %,

all amounts being based on the total weight of the aqueous particle-free fluid.

2. The aqueous particle-free fluid of claim 1 , wherein the solvo-surfactant is an asymmetric polyhydric alcohol or mono-alkyl ether derived from a polyhydric alcohol.

3. The aqueous particle-free fluid of claim 1 , wherein the solvo-surfactant is a C 1 to C 4 mono-alkyl ethyl derived from a polyhydric alcohol.

4. The aqueous particle-free fluid of claim 1 , wherein the solvo-surfactant is present in an amount of at least 3 weight % and up to and including 6 weight %, based on the total weight of the aqueous particle-free fluid.

5. The aqueous particle-free fluid of claim 1 , which has a pH of at least 8 and up to and including 11, and further comprises an aliphatic amine.

6. The aqueous particle-free fluid of claim 1 , further comprising a surfactant different from the solvo-surfactant, which surfactant is present in an amount of at least 0.01 weight % and up to 10 weight %, based on the total weight of the aqueous particle-free fluid.

7. The aqueous particle-free fluid of claim 1 , further comprising a humectant or co-solvent that is different from the solvo-surfactant.
