Primer composition for process of inkjet printing

A primer composition for a process of inkjet printing, which is a primer composition containing a resin emulsion, a cohesion promoter for promoting cohesion of the primer composition, a surfactant, and water, the primer composition characterized in that:

• the resin emulsion includes at least one emulsion selected from polyolefin-based resin emulsions and urethane-based resin emulsions;
• the surfactant includes one or more surfactants (A) selected from the group consisting of acetylene-based surfactants and silicone-based surfactants, and nonionic surfactant(s) (B) other than the surfactant(s) (A);
• the nonionic surfactant(s) (B) is/are nonionic surfactants having a HLB value of 10.0 or greater but under 15.5 and also having multiple polyoxyalkylene groups in a molecule, and include(s) one or more nonionic surfactants selected from the group consisting of polyoxyalkylene group-containing fatty acid glyceryls, polyoxyalkylene group-containing aliphatic amines, and polyoxyalkylene group-containing sorbitan fatty acid esters;
• and
• a content percentage of the nonionic surfactant(s) (B) in the primer composition is more than 0% by mass and 3.0% by mass or lower.
