Acrylic

Synthetic paints, with pigments dispersed in a synthetic vehicle made from polymerized acrylic acid esters, the most important of which is polymethyl methacrylate. First used by artists in the late 1940s, their use has come to rival that of oil paints because of their versatility. They can be used on nearly any surface, in transparent washes or heavy impasto, with matte, semi-gloss, or glossy finishes. Acrylic paints dry quickly, do not yellow, are easily removed with mineral spirits or turpentine, and can clean up with soap and water.(Artlex.com)
