    • A retroreflective applique is provided that includes a layer of optical lens elements partially embedded in and protruding from a transfer adhesive layer prepared from ingredients comprising a vinyl plastisol and a substantially nonhydrolyzed aminosilane adhesion promoter; wherein the aminosilane adhesion promoter is used in an amount effective to produce an applique capable of: (a) retaining at least about 60% of its initial retroreflectivity after being laminated to 65/35 polyester/cotton blend fabric (100 g/m.sup.2) at about 174.degree. C. and about 2.8 Kg/cm.sup.2 pressure for about 20 seconds and subjected to home laundering conditions five times; and (b) retaining at least about 40% of its initial retroreflectivity after being laminated to 65/35 polyester/cotton blend fabric (100 g/m.sup.2) at about 174.degree. C. and about 2.8 Kg/cm.sup.2 pressure for about 20 seconds and subjected to home laundering conditions twenty-five times.
