ABSTRACT:
Laser-addressable thermal transfer donor elements for producing color proofs, printing plates, films, printed circuit boards, and other media are disclosed. The thermal transfer donor elements include a substrate with a gas-producing polymer layer thereon, and an array of discrete nanostructured elements embedded within the gas-producing polymer layer. The gas-producing polymer layer has a thermally available nitrogen content of greater than about 10 weight percent. Each of the nanostructured elements includes an elongated structure conformally coated with a radiation absorbing material. A thermal mass transfer material (e.g., a metal or colorant such as a dye or pigment) is included in or over the gas-producing polymer layer.
