SolarFast dyes are light-sensitive and only develop color and become permanent upon exposure to sunlight (UV). This unique property means SolarFast may be used to create remarkably detailed photographs, photograms and shadow-prints on paper or fabric by harnessing the power of the sun! Anything you place on the painted surface to block the light will create a print in a matter of minutes, whether that’s a solid object (toys, tools, plants, lace, etc.), a photographic negative (an image digitally printed onto a transparency) or shadow (from folds in the fabric or a 3D object).
