The present invention provides water-based ink and coating compositions having a high renewable resin content. The ink and coating compositions of the invention comprise equal to or greater than 65% (w/w) renewable resins, based on the total combined weight of the resins. Renewable resins derived from gum rosins are preferred. The ink and coating compositions of the present invention exhibit physical properties (e.g. adhesion and resistance) that are as good as, or better than, current commercially available inks (e.g. acrylic based inks not containing renewable material).

Provided are a textile printing ink set including a pretreatment liquid including a cationic compound having a molecular weight per cationic valence of 150 to 220, and an ink composition including a water-insoluble dye, a dispersing agent, and water, wherein the dispersing agent is at least one selected from the group consisting of a urethane resin, a urea resin, and a urethane-urea resin; and a textile printing method.

A liquid composition set is provided. The liquid composition set comprises: a liquid composition X comprising a polymerizable compound X and a solvent X; and a liquid composition Y comprising a solvent Y. The liquid composition X is to form a porous resin, and has a smaller surface tension than the liquid composition Y.
