Zusammenfassung:	A transfer film configured for transferring optical beads to a substrate is disclosed. The transfer film typically contains optical beads (68), a temporary bead carrier layer (62) retaining the optical beads, and an optional adhesive layer (74) configured to permanently adhere the optical beads to a substrate. The temporary bead carrier layer contains a carrier backing (64) and a heat- resistant carrier coating (66) that temporarily holds the beads during application at elevated temperatures to a substrate. The carrier coating is formed such that it initially softens to retain the beads, but is then hardened or thermoset (such as by crosslinking) to prevent the carrier coating from softening during transfer of the beads to a substrate.
