Abstract
A retroreflective article that includes a first layer that includes a copolyester ether composition, and a second layer that includes a retroreflective structure juxtaposed in at least a partially overlying relationship to the first layer is disclosed. Also disclosed is a method of forming a retroreflective article that includes providing at least a copolyester ether composition layer, and providing a retroreflective structure in a juxtaposed and at least partially overlying relationship to the composition layer.
Claims29
A retroreflective article comprising a first layer comprised of a copolyester ether composition, and a second layer comprised of a retroreflective structure juxtaposed in at least a partially overlying relationship to the first layer, wherein the retroreflective structure includes a microprismatic structure, and wherein the first layer is coupled to a viewing surface of the second layer, and wherein the first layer has temperature stability in a temperature range of between about −100° F. and 400° F.
A retroreflective article comprising a first layer comprised of a copolyester ether composition, and a second layer comprised of a retroreflective structure juxtaposed in at least a partially overlying relationship to the first layer, wherein the retroreflective structure includes a microprismatic structure, and wherein the first layer is coupled to a viewing surface of the second layer, and wherein the retroreflective article has a brightness that is equal to or exceeds a brightness standard set by European Standara EN 471 for High-visibility warning clothing for professional use.
A retroreflective article comprising a first layer comprised of a copolyester ether composition, and a second layer comprised of a retroreflective structure juxtaposed in at least a partially overlying relationship to the first layer, wherein the retroreflective structure includes a microprismatic structure, and wherein the first layer is coupled to a viewing surface of the second layer, and wherein the copolyester ether composition comprises a blend ratio comprising between about 95 to about 5 weight percent of copolyester ether and about 5 to about 95 weight percent of copolyester composition.
