Abstract:
The present invention relates to projection films and methods of making the same. In particular, the present invention relates to a projection film whereby the microspheres exhibit improved alignment on the light exit surface and have alignment on the light entrance surface that varies according to the individual microsphere diameter. In another embodiment, the present invention relates to a projection film that has the attributes of variable gain within the single projection film. In another embodiment, the present invention relates to an exposed microsphere projection film construction that provides modification of the head-on and angular pattern of light transmission (gain).
