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: Retroreflective article having tailored optical properties and method for making the same. Retroreflective articles according to the present application comprise deformed cube corner elements having reduced optically active volume and reduced active volume height. Exemplary retroreflective articles have at least one of minimized contrast caused by seam welds, tiling lines or defects under retroreflective conditions, markings discernible at different viewing conditions and reduced overall retroreflectivity.
