Polyurethane materials exhibit excellent colorability; by incorporating dyes or pigment pastes, a wide range of colored polyurethane products can be produced, including colored polyurethane flexible foams, elastomers, and synthetic leathers.

Ink is a viscous, homogeneous liquid composed of a blend of various functional ingredients, which can be applied to substrates in a variety of ways—such as printing, spraying, or blade coating—to reproduce designed graphics and text. The formulation of ink is highly complex; in addition to the basic components—pigments, binders, and solvents—it also includes a range of functional additives that enhance ink performance and improve its printability and overall compatibility with the substrate.
