摘要:
Pre-treatment compositions include organic liquids and cross-linking initiators. Pre-treatment compositions are included in ink sets that also include oil-based ink compositions. Oil-based ink compositions include organic liquids, unsaturated fatty materials having terminal polar functional groups, colorants, and metal salts. Methods for ink-jet printing use pre-treatment compositions and oil-based ink compositions.
