摘要:
An intermediate media having a transferable UV stabilizer receives a printed image. A transferable UV absorber and/or free radical scavenger is present. The image, or dye layer, and UV stabilizer are transferred to a final substrate during subsequent heat transfer and activation. Alternatively, the UV stabilizer may be heat transferred from the intermediate transfer media onto a previously transferred image. The UV stabilizer is resistant to laundering at elevated temperatures after transfer and imparts no hand to the final substrate. The intermediate transfer media may comprise multiple layers including a layer containing one or more UV stabilizers. A release layer may be applied beneath the UV stabilizer layer. The release and UV stabilizer layers may sit beneath a dye screening layer. One layer may be a liquid permeable, gas impermeable membrane.
