Adhesive articles and methods of applying and activating adhesive articles to bond to substrates using a fluid application aid. Preferably, the substrates are traffic devices such as traffic cones and the adhesive articles are retroreflective cone collars or sleeves.

Fluid-activatable adhesive articles and methods

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.

Fluorescent red composition and articles made therefrom

A fluorescent red article comprising a polymer matrix; and a perylene dicarboximide dye, wherein the article has 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, and laminates, retroreflective materials, and methods of making thereof.

Fluorescent red article and retroreflective article made therefrom

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.
