Abstract
The present invention provides reflective films and other optical bodies which exhibit sharp bandedges on one or both sides of the main reflection bands. The optical bodies comprise multilayer stacks M.sub.1 and M.sub.2, each having first order reflections in a desired part of the spectrum and comprising optical repeating units R.sub.1 and R.sub.2, respectively. At least one of the optical repeating units R.sub.1 and R.sub.2 varies monotonically in optical thickness along the thickness of the associated multilayer stack.
