Abstract
A pre-treatment composition for inkjet printing, comprising water, a water-soluble multi-valent metallic salt, a wax, a non-ionic dispersant and a resin particle, the resin particle is stabilized by a non-ionic group or non-ionic or amphiphilic compound. A fluid set comprising the pre-treatment composition and an aqueous inkjet ink is suitable for printing liners for corrugated packaging, folding boards or a corrugated card boards.
Claims20
