Abstract
Disclosed is a packaged element containing (a) a substrate that transmits less than about 0.5% of actinic radiation and has at least one recess, (b) a cover that transmits less than about 0.5% of actinic radiation and transmits at least part of the visible light spectrum, (c) a structure for maintaining the cover in contact with the substrate such that the cover filters incident radiation entering the recess, and (d) an element located in the recess and having a substance thereon that is curable by exposure to the actinic radiation. Also disclosed is an article containing (a) a substrate having at least one recess with an interior surface, (b) an element having a tacky substance on a surface thereof, and (c) a structure for positioning the element inside the recess such that the tacky substance does not separate from the element upon removal from the recess.
