First Claim
Patent Images
1. A unitary retroreflective composite preprinted sheeting material for use in sign-making, comprising:
- (a) a first resinous material having first and second oppositely facing surfaces;
(b) a second resinous material overlaying and laminated to said first surface of said first resinous material;
(c) a printed legend disposed between said laminated first and second resinous materials; and
(d) retroreflective optical elements provided in juxtaposition to said second surface of said first resinous material to form a preprinted retroreflective sheet material of unitary laminate for use in making signs.

Abstract
A retroreflective unitary laminate material having an acrylic layer on which a sign legend is printed and which is covered by an ultraviolet absorbent overlay that has poor affinity for paint and low surface tension thus protecting the printed sign from deterioration due to weathering and enabling the sign to be readily cleansed without damaging the printed signs, and minimizing water beading on the sign front face.

13. A reflective sign comprising:
-
a substrate forming the base layer of the sign; and a unitary laminate of retroreflective material adhesively attached to the substrate, the unitary laminate comprising; a resinous sheeting material; a legend printed on the forward facing surface of the resinous material; an ultraviolet absorbing overlay laminated to the forward surface of the resinous material having the printed legend thereon; a cube corner type optical pattern embossed upon the rear surface of the resinous sheeting material; a layer of hydrophobic granular silica material over at least a portion of the embossed pattern; a back coating applied to the silica material and to any exposed areas of the embossed rear surface to provide a flat, smooth surface; and an adhesive means for attaching the unitary laminate of retroreflective material to the substrate. - View Dependent Claims (15, 16, 17)

14. A backing means comprising:
-
a substrate forming the base layer of the sign; and a unitary laminate of retroreflective material adhesively attached to the substrate, the unitary laminate comprising; a resinous sheeting material; a legend printed on the forward facing surface of the resinous material; an ultraviolet absorbing overlay laminated to the forward surface of the resinous material having the printed legend thereon; a cube corner type optical pattern embossed upon the rear surface of the resinous sheeting material; a layer of backing material over at least a portion of the embossed pattern; an adhesive means for attaching the unitary laminate of retroreflective material to the substrate.
