Patent leather is a type of coated leather that has a very glossy, shiny finish. The coating process was brought to the United States and improved by inventor Seth Boyden of Newark, New Jersey in 1818, with commercial manufacture beginning September 20, 1819. Boyden's process, which he did not patent, used a linseed oil–based lacquer coating. Modern patent leather usually has a plastic coating. ==History== In general, patent leather begins as a superior grade of fine grain leather that undergoes a process to achieve the glossy look. A member from the Baudry/Boudrie from Brussels Belgium invented patent leather in the late 1700s.〔Lives and times: my life - my family: Jessie Yvonne Boudrie-Allen / written by Christine Allen; dictated text by Jessie Yvonne Allen〕 An early reference to patent leather is in the 1793 British periodical, ''The Bee, or Literary Weekly Intelligencer'', which notes—in an article entitled "Hand's patent leather"—that "a gentleman of the name of Hand" in Birmingham, England obtained a patent for preparing flexible leather having a glaze and polish that renders it impervious to water and need only be wiped with a sponge to restore it to its original luster. In November 1799, inventor Edmund Prior of Holborn, London, England received a patent for a method of painting and colouring all kinds of leather, and in January 1805, inventor Charles Mollersten of Hackney Wick received a patent for applying a chemical composition in the preparation of hides, skins, and leather to give "a beautiful gloss." However, patent leather primarily owes its popularity to Seth Boyden. In 1818, Boyden received a piece of German manufactured patent leather (said to be a German military cap front) from a local carriage manufacturer and used that to investigate the possibility of creating a version of leather in the United States that was treated in such a way that the material would be decidedly more dressy than work boots and similar leather goods, but retained its desirable qualities of protection and durability. To reverse engineer the European patent leather, Boyden set up a shed at the Malleable Cast Iron Foundry of Condit & Bowles at 25 S Orange Avenue in Newark, New Jersey and ultimately discovered a way to produce his own patent leather.〔 Using a formula that was based on a series of treatments using layers of linseed oil-based coats, the new shiny leather began commercial production on 20 September 1819. Boyden’s efforts resulted in the production of glossy leather that quickly caught on as a complement for formal dress. Ironically, Boyden never patented his inventive process.〔 A subsequent European method of manufacture was described in 1906 as follows: The invention of plastics subsequently changed the methods for producing patent leather. Plastic finishes were able to produce effects similar to the application of several treatments with linseed oil, with the advantage of considerably less monetary investment on the part of the producer. Over time, the development of synthetic resins further simplified the process and cut production costs even further, making the mass production of patent leather possible. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「patent leather」の詳細全文を読む スポンサード リンク
