ABSTRACT:
Retroreflective images are formed on garments and other substrates with a transfer sheet material that comprises a support sheet, a dense continuous monolayer of transparent microspheres partially embedded in the support sheet, and a thick transfer layer printed over a limited portion of the continuous layer of microspheres in an imagewise pattern. In use the transfer sheet material is laid against a substrate, the transfer layer adhered to the substrate, and the support sheet stripped away. The transfer layer remains in place and pulls the microspheres from the support sheet, leaving a sharply defined design that is retroreflective over the full area of the design.
