Claim 0:
1. An inkjet ink and primer fluid set comprising:
a) an aqueous primer composition comprising a multivalent cation salt and a polymeric binder, wherein said composition forms a coating with a dry thickness of from 0.4 to 5.0 micron upon application onto a non-porous plastic substrate, and said coating results in a haze increase of less than 10 on said substrate, said multivalent cation salt is present at an amount less than 20 wt %, based on the total weight of the primer composition, and said polymeric binder is not soluble in water, is stable in the presence of said multivalent cation, and is selected from the group consisting of urethane polymer, acrylic polymer and vinyl polymer;
b) an aqueous white inkjet ink comprising a titanium oxide pigment dispersion, and a polyurethane binder or an acrylic binder, wherein said titanium oxide pigment dispersion having a particle size with D50 in the range of 200 to 350 nm; and
c) one or more aqueous non-white colored inkjet inks, wherein at least one of the inks comprising a pigment dispersion, and a second polyurethane binder or a second acrylic binder.
