About this product range
Paint fast or paint slow with Chroma Atelier Interactive Acrylics!
Formulated using a patented technology, Atelier Interactive Acrylics offer artists a versatile set of working properties unlike those of any other paint. In application, they perform like conventional acrylics, allowing for traditional painting and glazing techniques. Yet they also give you unique control over the drying process — plus the ability to reactivate the paint, even when dry.
Professional-quality Atelier Interactive Acrylics are lightfast and archival, with exceptional consistency, brushability, and color load. They dry to a velvety satin finish. When purchased in 80 ml tubes, they offer one-third more paint than standard 60 ml tubes — and often costs less.
