Water transfer printing process, Bixian is sprayed with primer on the metal and ceramic surface of God, otherwise the transfer is not easy to use. After the transfer, it needs to be washed and dried, and finally sprayed with protective paint. 13 70% water transfer is suitable for pattern transfer with only the whole surface, but it is not suitable for text in the transferred pattern. It will be accepted and accepted. In addition, the drying temperature of the water transfer operation cannot be too high, and the drying time often takes 2 to 3 hours, which is not only consumes but also consumes energy. For heat transfer, you must first apply powder or paint on the surface of the metal or shouting, and then heat transfer it. The disadvantage is that if there is any difference between the thermal transfer paper and the transfer surface, the image resolution of the position will be conspicuous. In addition, the sublimation transfer color is extremely sensitive to the transfer temperature and time variation, and a slight second of the second, which causes a difference in color. . The thermal transfer method is currently applied to the surface of various halls, pp, plastic, wood 'coated metals, etc.'. The principle ^^ prints the color pattern on the film of the heat-generating substrate (by the release process), = the transfer device dedicated to t, and transfers it to the surface of the product by hot stamping. The quality of the thermal transfer process is reliable. Technically stable, well-matched material formulation and equipment. However, for thermal transfer applications on non-absorbent surfaces such as metal, glass, and taman, it is necessary to apply an interface agent, resin, or other coating in advance to stabilize the ink. The current thermal transfer film system is made of facts, and the ugly area is small. In clothes, cloth bags, hats, pillows, mugs, plates, monuments, watch cases, mouse pads, cups, hanging calendars. , medals, pennants, work cards, house cards, mirror boxes, metal jugs, etc. are acceptable, but if you want to make large pieces of building materials, 200846199 such as color waves, large glass plates or whole tiles, etc. The transfer, technical still has to be broken. SUMMARY OF THE INVENTION The object of the present invention is to break through the limitations of the prior art, and provide a thermal transfer film and a process capable of directly performing large-area and continuous thermal transfer on various metals, glass or ceramic articles, and the process is not limited. A printed pattern having a good strength of the film structure is formed directly on the surface of the flat or curved article. The process of the thermal transfer film is continuously printed on a continuous roll of continuous plastic film or _ paper on a roll surface with gravure printing or other printing equipment to produce a monochromatic or color color. The high temperature resistant pigment ink layer is coated with a heat resistant/heat-resistant hot melt adhesive layer on the surface of the high temperature resistant pigment ink layer. The steps of thermal transfer include: · a degreasing and dust removing steps for purifying the transferred surface of the article; b. a pseudo fixing step, using a high temperature resistant pigment ink and a heat resistant heat reaction The thermal transfer film of the sol layer is subjected to thermal transfer on the transfer surface of the article of step a. 'The high temperature resistant pigment ink layer and the high temperature resistant heat reaction type thermal enamel layer are first served on the transfer surface. The 'c baking step' allows the high temperature resistant pigment ink layer and the high temperature heat reactive type hot melt layer to be firmly bonded to the transfer surface of the article. • [Embodiment] ^ In order to make the above objects, features and advantages of the present invention more obvious and easy to understand, the following is a better description of the details, and with the accompanying drawings, a detailed description is as follows: The schematic diagram of the embodiment of the step of recording the 4G structure of the present invention comprises the following steps: 1. preparation step 'preparation _ high-temperature film 1 containing a release coating on the surface, so as to contain at least one high temperature resistant film 10 and a coating layer n; 8.2 printing step, using a printing device 2 to print a high temperature resistant ink layer 20 on the surface of the release layer 1; and ° 'Li 3. Coating step' utilization - coating reduction 3 coating-rich high-temperature heat-reactive type heat transfer on the high temperature ink layer 20, in order to form a high temperature heat-resistant hot melt adhesive layer on the high temperature resistant ink layer 2Q. u By the above steps, a large-area, unlimited-length enamel film can be quickly produced. The high temperature resistant film i containing the release agent coating in the step 1 may be a release paper or a release film, and the printing performed in the step 2 may be provided in a package manner.
步驟2的印刷設備2係可為-般的凸版印刷機、柔性板印刷機或凹版 印刷機之類的印刷設備，以耐高溫油墨連續印刷有限或無限長的文字、影 像或圖案，在離型繼層10的表面印出單色或彩色的耐高溫油墨層2〇。/ 遇印夏大、要求印刷品質精美時，可翻凹版印刷機，因為凹版印刷的油 墨表現力強，色調豐富，且所印出的油墨層也雜〜般凸版或平版為厚。 選用耐高溫顏料油墨的目地，係為使熱轉印的耐高溫油墨層2()不會經過高 溫烘烤而改贿色；較佳者，，用耐高溫兼可抗料制耐高溫油墨同 使轉印產品的顏色在光線較強的環境中亦能經久不视。 步驟3的耐高_反趟熱轉％可顧—耐高溫的高分子埶反應型 熱熔膠。_耐高溫熱反應義熔膠的目地，是為了讓縣與耐高溫轉 層 起、、二過同，皿烘烤、疋著於物品表面後，在-般常溫度溫中易於維梏 穩定的物理性質。 〃 tThe printing device 2 of step 2 can be a printing device such as a letterpress printing machine, a flexographic printing machine or a gravure printing machine, and continuously prints limited or infinitely long characters, images or patterns with high temperature resistant ink, in the form of release. A monochromatic or colored high temperature resistant ink layer 2 is printed on the surface of the layer 10. / When printing in the summer and demanding the printing quality, you can turn the gravure printing machine because the ink of the gravure printing is strong, the color is rich, and the ink layer printed is also thick or thick. The purpose of selecting high temperature resistant pigment ink is to make the heat transfer resistant high temperature ink layer 2 () not change the brittle color after high temperature baking; preferably, it is made of high temperature resistant and resistant high temperature resistant ink. The color of the transferred product can be ignored for a long time in a strong light environment. Step 3 is resistant to high _ 趟 趟 heat transfer % can be considered - high temperature resistant polymer 埶 reactive hot melt adhesive. _ The purpose of high temperature thermal reaction melting adhesive is to make the county and the high temperature resistant layer turn up, and the second is the same. After the dish is baked and squatted on the surface of the article, it is easy to maintain stability at normal temperature. Physical properties. 〃 t
