Abstract: Retroreflecting optical constructions are disclosed. A disclosed retroreflecting optical construction includes a retroreflecting layer that has a retroreflecting structured major surface, and an optical film that is disposed on the retroreflecting structured major surface of the retroreflecting layer. The optical film has an optical haze that is not less than about 30%. Substantial portions of each two neighboring major surfaces in the retroreflecting optical construction are in physical contact with each other.

Abstract: An apparatus for casting a patterned surface on both sides of an opaque web. The apparatus includes a first patterned roll, a second pattered roll, and a means for rotating the first and second patterned rolls such that their patterns are transferred to opposite sides of the opaque web while it is in continuous motion. During this process, their patterns are maintained in continuous registration to within at least 100 micrometers.
