I mentioned vinyl siding before - I happened to have a bunch on
hand.  It is of course UV resistant.  Since the signs are meant for a
working life measured in days I doubt that's much of a consideration
for them.  I wouldn't worry *too* much about that though, since these
things live in the shade.

Thin aluminum - chimney flashing might be thick enough to work
with.  Your local gutter contractor will have lovely stuff in huge
rolls, probably anodized on one side with epoxy paint on the other -
he sticks it into one end of a machine that he brings to the job, and
guttering comes out the other.
1/8" acrylic or <senior moment - the other stuff> sheet
GRP
1/8" Masonite with aluminum foil varnished on (e.g. dead clipboards)
Something thin and stiffish and waterproofy.

Yrs,
