<p>The invention is a radiation curable liquid resin that can be used to make a clear and colorless, three-dimensional article by a stereolithography process. The clear and colorless three-dimensional articles have a clarity and transmittance of greater than about 67% as measured by UV-Visible spectrophotometer in the 400-500 nm range; and a lack of color as measured by a b* value of between about minus 0.5 (-0.5) and about positive 2.5 (+2.5) in the CIELAB color space using a spectrophotometer in the visible wavelengths of 400-750 nm.</p> |
