AI Technical Summary
Technical Problem
Existing primer compositions prioritize adhesion but compromise blocking resistance, creating a trade-off that hinders simultaneous achievement of both properties.
Method used
An ink set comprising a primer composition with 80% or more of ether ring-containing and saturated hydrocarbon ring-containing polymerizable compounds, and an ink composition containing the same compounds, ensuring excellent adhesion and blocking resistance through a balanced composition.
Benefits of technology
The ink set achieves superior adhesion to recording media and prevents blocking, maintaining performance over time and at high temperatures.

Abstract
We can provide an ink set that achieves both excellent adhesion and resistance to blocking. [Solution] An ink set comprising a primer composition and an ink composition, wherein the primer composition contains one or more compounds (A) selected from ether ring-containing polymerizable compounds (A-1) and saturated hydrocarbon ring-containing polymerizable compounds (A-2), the content of compound (A) in the primer composition is 80% by mass or more of the total amount of polymerizable compounds, and the ink composition contains compound (A).
