摘要:
Composition suitable for free radical, radiation curable coating comprising at least one polyester having unsaturated backbone and at least one compound having two to six propenyl ether groups, and optionally, a free radical photoinitiator. The equivalent ratio of propenyl ether groups to maleimide, maleate and/or fumarate groups in the polyester is preferably about 5:1 to about 1:5.The process for curing the composition includes exposing it to ionizing radiation and/or ultraviolet light. The resultant cured coatings and coated articles are similar in performance to their vinyl ether analogues, but the propenyl ethers are easier to prepare than the vinyl ether analogues.

Exemplary embodiments of the present invention comprise systems and method for providing information to an in-store customer. An embodiment of the system includes several radio frequency identification (RFID) tags placed in predetermined areas within the shopping area. A mobile device, carried by the customer, receives signals from the RFID tags. The signals are used to determine the location of the customer within the store. The determined location is used by an information server to return location-specific information and advertising to the mobile device. The mobile device displays the location-specific information and advertising to the customer.
