  • Patent number: 5879494
    Abstract: A method of forming apertures generally greater than about 0.05 square millimeters in a thin sheet material. The thin sheet material includes a first side and a second side at least one side of the thin sheet material is substantially coated with an adhesive. The method comprises the steps of (a) placing the adhesive-coated thin sheet material on a patterned anvil having a pattern of raised areas wherein the height of the raised areas is equal to or less than the thickness of the thin sheet material and the adhesive; and (b) subjecting the thin sheet material to a sufficient amount of sonic vibrations to aperture the thin sheet material and the adhesive; and whereby the thin sheet material and the adhesive is apertured in a pattern generally the same as the pattern of raised areas on the patterned anvil.

  • Patent number: 5837347
    Abstract: 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.
