The anti-reflective acrylic sheet from Tru-vue about which Norman
Muller inquired will initially be made on 1/8" abrasion-resistant
stock in a roughly 40" X 50"  size. This will limit its usage
somewhat. For smaller paintings it should not be too flexible, but a
full sheet of material in this thickness would have to be spaced
well away from the painting to ensure that it does not touch the
painting surface if the frame is laid flat. As with any acrylic
sheet, it should not be used to make sealed packages that are going
to venues that have dry climates, lest the acrylic warp inward
toward the painting as it dries out on its outer surface. It will
not be a candidate for use with friable media, either, but should be
quite useful when properly spaced away from the painting for those
small and moderate size examples. If this material does find a
market, the makers might be convinced to make it in thicker, larger
sizes.
