Pigments dispersed with acrylic resin (synthetic resins made by polymerization of acrylic acid ester
A relatively new water soluble pigment made from plastic. It dries faster than oils, and when dissolved, they can be used as water colors.
Resins resulting from the polymerization of derivatives of acrylic acids including esters of acrylic acid, methacrylic acid, acrylonitrite, and their copolymers. They can be carried in a water or solvent solution and they are film-forming materials.
