Abstract
An aqueous pre-treatment liquid for use in ink jet printing includes water and magnesium-disulfamate. Such pre-treatment composition is non-yellowing and crystal-free and shows good jetting properties. These properties are retained even when a solid co-solvent is added to the composition for anti-curl improvement, thereby enabling to provide non-yellowing pre-treatment liquids with good jetting properties and anti-curl behavior.
