Abstract
A primer composition including a resin emulsion, an aggregation accelerator, a surfactant, and water, the surfactant containing one or more of acetylene-based surfactants and silicone-based surfactants, and a nonionic surfactant other than the surfactant, the nonionic surfactant having an HLB value of 10 or above and below 15.5 and having multiple polyoxyalkylene groups, and the proportion of the nonionic surfactant in the primer composition is 3 mass % or below. The primer composition has excellent storage stability and makes it possible to form a primer layer that has excellent transparency and that produces excellent bleeding resistance and printability when a solid image is printed by an aqueous inkjet ink composition.
