  • Fluorescent red composition and articles made therefrom
    Patent number: 6572977
    Abstract: A fluorescent red composition providing a coating having chromaticity coordinates (x, y) within the area defined by (0.648, 0.351), (0.735, 0.265), (0.629, 0.281) and (0.565, 0.346) in terms of the CIE 1931 Standard Colorimetric System and measured using 0/45 geometry and evaluated with CIE Standard Illuminant D65 and a fluorescence luminance factor of at least about 8; articles comprising the composition or coating, and methods of making.

  • Conformable embossable retroreflective sheeting
    Patent number: 5882771
    Abstract: The present invention provides a retroreflective sheeting including: optical elements arranged in substantially a monolayer; a spacing layer in which the optical elements are at least partially embedded; a specularly reflecting layer underlying the spacing layer; and a bead bond layer in which the optical elements are at least partially embedded. The bead bond layer includes an aminoplast-crosslinked polymer comprising urethane groups, wherein prior to crosslinking the polymer has a glass transition temperature (Tg) of less than about 0.degree. C.
