And like all acrylics, it dries quickly and permanently, with no smudging or bleeding when rewetted or layered.Keep it fluid with Liquitex Acrylic Ink, now with 20 new colors including a range of fluorescents. Made with fine art pigments, Acrylic Ink is perfect for layering washes of color, adding in detail with a fine brush, dropping pools of flowing color directly on paper, splatter brushing, and pen & ink drawing.
