Laser-induced thermal dye transfer using black metal-coated substrates. |
摘要 |
<p>This invention relates to a laser imageable donor material that is capable of transferring pigment to a receiver, such as plain paper, polymeric film, metal and the like. The donor material is composed of at least a transparent film, an overlying layer of vapor coated black aluminum, and a dye coating or pigment coating dispersed on top of the black aluminum. A material which generates gas when irradiated may also be present as a separate layer under or in the dye or pigment layer and above the black aluminum layer. The construction can be addressed with diode lasers and diode-pumped solid state lasers. The invention can be used to produce large format digital halftone color proofs using high power air-cooled diode-pumped Nd:YAG and Nd:YLF lasers. Other materials could be transferred from the donor sheet in this process as well as the colorant (dye or pigment) layer.</p> |
