Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A primer composition comprising a resin emulsion, an aggregation accelerator, a surfactant, and water, wherein the surfactant contains one or more surfactants (A) selected from the group consisting of an acetylene-based surfactant and a silicone-based surfactant and a nonionic surfactant (B) other than the surfactant (A), the nonionic surfactant (B) has an HLB value of 10 or more and less than 15.5 and has a plurality of polyoxyalkylene groups, the nonionic surfactant (B) is one or more nonionic surfactants selected from the group consisting of a polyoxyalkylene group-containing fatty acid glyceryl, a polyoxyalkylene group-containing aliphatic amine, and a polyoxyalkylene group-containing sorbitan fatty acid ester, and a proportion of the nonionic surfactant (B) in the primer composition is 3% by mass or less. 2. The primer composition according to claim 1 , wherein a mass ratio of the surfactant (A) to the nonionic surfactant (B) (surfactant (A)/nonionic surfactant (B))) is 0.01 or more and 100 or less. 3. A primer layer formed from the primer composition according to claim 1 . 4. An ink set comprising the primer composition according to claim 1 and an aqueous inkjet ink composition. 5. A printed matter obtained by performing printing using the ink set according to claim 4 . 6. An image formation method using the ink set according to claim 4 .
