Title:
【発明の名称】可撓性再帰反射シートを含む物品
Document Type and Number:
Japanese Patent JP2001508367
Kind Code:
A
Abstract:
An article comprising (a) a curved substrate having a surface energy below about 38 dynes/cm<2>; (b) flexible retroreflective sheeting; and (c) a crosslinked pressure-sensitive adhesive adhering the sheeting to the curved substrate. The adhesive contains sufficient polar monomer and tackifier, and is sufficiently crosslinked, to (i) have a glass transition temperature less than -15° C., (ii) permit the sheeting to remain firmly bonded to a low density polyethylene barrel without buckling when cooled from 49° C. to -1° C., and (iii) provide an adhesive bond to the barrel that exhibits increased energy absorption when tested for impact resistance at 0° C. according to ASTM D4272. The adhesive can be manufactured by partially polymerizing some of the ingredients in a pouch using UV radiation, dispersing the pouch and its contents in the other ingredients using an extruder, extrusion coating the adhesive and then UV crosslinking the coating.
