A decal (, , or ) or transfer is a plastic, cloth, paper or ceramic substrate that has printed on it a pattern or image that can be moved to another surface upon contact, usually with the aid of heat or water. The word is short for ''decalcomania'', which is the English version of the French word ''décalcomanie''. The technique was invented by Simon François Ravenet, an engraver from France who later moved to England and perfected the process he called "décalquer" (which means to copy by tracing); it became widespread during the decal craze of the late 19th century. ==Properties== Decal is composed of the following layers from top to bottom: #A paper or film face-stock makes up the top layer of the labelstock. The printing is done on the upper side of the facestock. #An adhesive layer is applied to the bottom of the face stock. #A silicone or release coating layer is applied to the upper side of the backing material. #A paper or film liner provides the bottom layer of the labelstock. #An RFID circuit (chip and antenna) can be included in the paper or film face stock. Different variations of decals include: ''water-slide'' or ''water-dip''; and vinyl ''peel-and-stick''. A water-slide (or water-dip) decal is screen-printed on a layer of water-soluble adhesive on a water-resistant paper, that must first be dipped in water prior to its application. Upon contact with water, the glue is loosened and the decal can be removed from its backing; overly long exposure, however, dissolves the glue completely causing the decal to fail to adhere. A ''peel-and-stick'' decal is actually not a decal as described above, but a vinyl sticker with adhesive backing, that can be transferred by peeling off its base. The sign industry calls these ''peel-and-stick'' vinyl stickers ''vinyl-cut-decals''. 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「decal」の詳細全文を読む スポンサード リンク
