Encapsulated-lens retroreflective sheeting is described which contains an improved binder layer. The binder layer is obtained from a film-forming mixture which comprises: (A) a vinyl chloride copolymer, (B) a thermoplastic polyurethane, and (C) an aminoplast resin. Such binder layer exhibits improved adhesion to metallized beads and …

Also in the encapsulated lens type retroreflective sheeting of above-described construction, at least one of the layers closer to the light-entering side (the side indicated by the arrow 40 in FIG. 3) than the sealed air layer (18), i.e., the surface-protective layer (1) and/or the printed layer(s) as shown in FIG. 3, may contain as blended ...

Retroreflective cool walls could improve upon diffusely reflecting cool walls by reflecting incoming beam radiation to the solar disc (if the retroreflection is three dimensional and ideal) or at least upwards (if the retroreflection is two dimensional and/or imperfect). ... [22] repeated this process for a Type 3 encapsulated lens glass bead ...

Encapsulated-lens retroreflective sheeting offers bright retroreflection and maintains that reflection even when wet with water. Such sheeting has been provided in flexible fabric supported forms for application to garments to make pedestrians wearing the garments more visible at night to drivers of approaching vehicles. Because the sheeting ...

This retroreflective sheeting can be encapsulated lens or prismatic. It is made of two layers: an outer translucent pigmented layer; and an inner reflective layer faced with glass beads or plastic prismatic lenses. The two layers are connected by a lattice, hence its distinctive 'honeycomb' appearance.

Retroreflective Sheeting Changes Moving from Encapsulated Lens Sheeting to Prismatic Lens Sheeting for Permanent Signs, what are the reasons, and is now the time? As Observed from an SUV, 100 Ft. away and looking straight towards the signs: On the top – Encapsulated Lens. On the bottom – Prismatic Lens

The retroreflective sheeting can be selected from the group consisting of an embedded-lens retroreflective sheeting and an encapsulated-lens retroreflective sheeting. Preferably, the retroreflective elements are substantially spherical in shape, ranging in a size from about 0.5 mm to about 1.2 mm.
