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.
