Patent number: 6180318Abstract: A method of imaging an article comprising a metal/metal oxide imageable layer with a laser beam. In particular, the present invention relates to a method for imparting a color image on the article. The method includes: a) providing an article including a substrate and an imageable layer, the imageable layer comprising a metal/metal oxide layer; b) imagewise applying a laser beam to the article; and c) in the portion of the article having the laser applied thereto, imparting a color to the metal/metal oxide layer different from the color in the non-imaged portion. Preferably, the imageable layer comprises aluminum/aluminum oxide. Also presented are imageable articles, and the resulting imaged articles.Type: GrantFiled: May 19, 1999Date of Patent: January 30, 2001Assignee: 3M Innovative Properties CompanyInventors: Robert C. Fitzer, Haitao Huang, Pierre H. LePere, Theresa A. McCarthy-Pohl, Robert D. Waid

Patent number: 6180315Abstract: Novel compositions for making structured color images and application thereof Compositions for making structured color images comprising (a) a soluble pigment precursor which can be transformed to an insoluble pigment by means of chemical, thermal, photolytic or radiation-induced method, and (b) a binder polymer or prepolymer, or a positive or negative resist-type resin which can be structured by crosslinking, polymerization or depolymerization by applying heat or electromagnetic irradiation. The compositions can be applied to optical and thermal recording, printing, and the production of color filters for Liquid Crystal Displays, with high accuracy, high transparency and high stability.Type: GrantFiled: December 10, 1999Date of Patent: January 30, 2001Assignee: Ciba Specialty Chemcials CorporationInventors: Ulrich Sch{umlaut over (a)}deli, John S.

Patent number: 6177234Abstract: A monochromatic or polychromatic proof of a high resolution master and a process and means for its preparation are described. The graphic arts industry requires monochromatic or polychromatic proofs having high resolution and tonally correct reproduction of halftone masters having frequency modulated screen or line screens with more than 80 lines/cm. These proofs are obtained by using image carriers having image-side surfaces with an average roughness of 1.1 &mgr;m maximum. Such color proofs are necessary to check color separations in the graphic arts industry for whether subsequent printing results are a tonally correct reproduction of the master.Type: GrantFiled: November 24, 1997Date of Patent: January 23, 2001Assignee: E. I. du Pont de Nemours and CompanyInventor: Bernhard Metzger

Patent number: 6165687Abstract: Standard array, programmable image forming process. The process includes the steps of providing or forming a standardized array of pixel sites (16) on a surface of a substrate (12), each pixel site (16) including at least one color element (18, 20, 22) or colored sub-pixel at a predetermined location on the substrate (12), and providing or forming an opaque layer (24) over the pixel sites (16) obscuring the color elements (18,20,22) or sub-pixels thereof, the opaque layer (24) being changeable for rendering selected of the color elements (18,20,22) or sub-pixels visible for forming the image. The substrate (12) can include a paper material or a plastics film such as a transparent film, and the pixels sites (16) can be mass produced thereon by a suitable process, such as ink printing process, a thermal printing process, a laser printing process or the like.Type: GrantFiled: June 29, 1999Date of Patent: December 26, 2000Assignee: Eastman Kodak CompanyInventor: Samuel Reele

Patent number: 6126284Abstract: A printing device according to the present invention includes a dye tank for containing a powdered vaporizable dye, an entrance section for liquefying the powdered vaporizable dye and a vaporizing section for radiating a laser light beam onto the liquefied dye transported to it by the entrance section for vaporizing the liquefied dye for thermal transcription of the vaporized dye onto a photographic paper. In this manner, printing may be made without employing an ink ribbon or a thermal head and hence the saving in power and the reduction in size and costs of the printing device may be achieved. Besides, the printing time may be shortened, while the size of the printing paper, may be set freely.A photographic paper according to the present invention includes a light absorbing layer between a receptor layer and a photographic paper base.Type: GrantFiled: June 28, 1999Date of Patent: October 3, 2000Assignee: Sony CorporationInventors: Shuji Sato, Masanori Ogata, Kengo Ito, Hiroyuki Shiota
