Patent number: 7223512Abstract: The present invention relates to a process for increasing the level of safeguard in respect of forgery of paper documents. For that purpose, applied to the paper document is a transfer film or laminating film having a laser-sensitive layer. This multi-layer body is then treated with laser radiation. In that case, a laser-induced marking is produced in the laser-sensitive layer, for example, by laser-induced bleaching, laser-induced color change or laser-induced blackening. Respective individualization of the document can be effected by way of that laser-induced marking.Type: GrantFiled: May 8, 2002Date of Patent: May 29, 2007Assignee: ORGA Systems GmbHInventors: Norbert Lutz, Gerhard Zinner, Matthias Schumacher, Ulrich Knaack, Dirk Fischer

Patent number: 7223514Abstract: A method of fabricating a donor substrate and a method of fabricating an organic light emitting display (OLED) using the donor substrate. The method of fabricating the donor substrate includes preparing a base substrate that includes at least one transfer region and at least one non-transfer region, forming a light-to-heat conversion layer on the base substrate and depositing a transfer layer selectively on the light-to-heat conversion layer and in the at least one transfer region of the base substrate using a shadow mask. To then make the OLED, laser induced thermal imaging is used to transfer the patterned transfer layer from the donor substrate to display regions in an acceptor substrate.Type: GrantFiled: September 28, 2005Date of Patent: May 29, 2007Assignee: Samsung SDI Co., Ltd.Inventors: Tae-Min Kang, Jae-Ho Lee, Seong-Taek Lee, Jin-Soo Kim

Patent number: 7198879Abstract: A method for forming a resist pattern on a substrate (18) places a donor element (12) having a layer of thermoresist material proximate the substrate. A gap is maintained such that the surface of the layer of thermoresist material is spaced apart from the surface of the substrate by a number of spacing elements. Thermal energy is directed toward the donor element (12) according to the resist pattern, whereby a portion of thermoresist material is transferred from the donor element (12) across the gap by ablative transfer and is deposited onto the substrate (18) forming the resist pattern.Type: GrantFiled: September 30, 2005Date of Patent: April 3, 2007Assignee: Eastman Kodak CompanyInventors: Timothy J.
