  • Patent number: 8153353
    Abstract: A method and a material for creating an antireflective coating on an integrated circuit. A preferred embodiment comprises applying a dark polymer material on a reflective surface, curing the dark polymer material, and roughening a top surface of the dark polymer material. The roughening can be achieved by ashing the dark polymer material in an ash chamber. The dark polymer material, preferably a black matrix resin or a polyimide black matrix resin, when ashed in an oxygen rich atmosphere for a short period of time, forms a surface that is capable of absorbing light as well as randomly refracting light it does not absorb. A protective cap layer may be formed on top of the ashed dark polymer material to provide protection for the dark polymer material.

The ionic latex polymer is present as latex particles that have been prepared in the presence of a stabilizer in an amount of at least 0.5% (by weight) that has an HLB value of 7 to 20. The stabilizer becomes associated with the latex polymer particles. Both thermographic and photothermographic materials can be prepared with such protective layers.

  • Patent number: 7018772
    Abstract: This invention relates to a method for transferring a protective overcoat for a thermal print wherein the protective overcoat is applied to a dye-donor element under predesigned conditions after thermal dye transfer, the dye-donor element comprising patches of dye for transfer to a thermal print to provide a protective layer thereon. In particular, the invention improves the process of providing an improved level of gloss to the transferred protective overcoat. The method involves a preselected duration between printing and peeling the transferable laminate patch, respectively, to and from the donor. The invention is particularly advantageous at lower line times, faster printing, for thermal prints with high gloss.
