Description of the invention: [Technical field to which the invention pertains] ^The invention relates to a method for producing paper having high gloss surface characteristics (hlgh_gl〇ss surf characteristics), particularly suitable for metal fresh ship metal photo miscellaneous f. Metallization of the surface [Prior Art] Paper having high gloss surface characteristics has many uses. For example, it can be commercially used to manufacture a wrapper such as a metallic luster, or a decorative paper for decorative use, and the like. In order to produce a paper having high metallic reflection, it is common practice to carry out a metallization plating treatment on a substrate paper having high gloss ((10) such as vap〇rizat^ coatmg). However, in order to achieve a high reflection effect, the paper used for the ship itself needs a surface having a high flatness, and these high flatness surfaces visually exhibit high gloss properties. Conventional techniques are based on the surface of paper or other suitable substrates, and the use of paper-making drapes to improve the flatness of the woven fabric pursues high degrees of association. But such practices increase the cost of the paper itself. SUMMARY OF THE INVENTION The object of the present invention is to provide a high gloss which can be used for metallurgy, and a coating method which can utilize low cost and low surface flatness as a substrate to form two glosses. Flat surface for, for example, metal vaporization addition. The invention thus provides a method for producing high-gloss paper for metallizing, the steps comprising: (8) coating a coating solution on a paper substrate; 1273152 (9) providing a layer of pressure-gloss with the paper substrate Pressing together to form a temporary composite structure 'the towel is coated with the silky coating - covering the coating solution on the paper substrate; (C) the coated coating in the temporary composite layer The coating solution is dried and solidified, and (6) the gloss providing layer is peeled off from the temporary hybrid layer structure; ^ the cured gloss coating remains on the paper f substrate to form a metal-treatable metal A high gloss paper formed with a glossy surface having a corresponding high flatness surface property of the high flatness surface of the layer. The present invention also provides a method for producing a metal-steamed high-gloss paper, the steps comprising: (a) coating a coating solution on a paper substrate; (b) providing a gloss layer with pressure The paper substrate is pressed together to form a temporary composite layer structure, and the gloss provides a high flatness surface covering the coating solution on the paper substrate; (4) coating the temporary composite coating The solution is lyophilized (匕; and (d) the gloss-providing layer is peeled off from the temporary composite layer structure, and the cured gloss coating is suspended on the substrate to form the high-gloss paper. Forming a glossy surface having a corresponding high flatness surface property of the high flatness surface of the gloss providing layer; performing a metal evaporation treatment on the shiny side of the glossy paper to plate a metal on the glossy surface a layer to form the metal-evaporated high-gloss paper. [Embodiment] The present invention produces a method for producing high-gloss paper for metal evaporation, which will be described in the following paragraphs. Better of non-limiting nature BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a schematic view showing the flow of manufacturing 1273152 paper having a high degree of uniformity according to a preferred embodiment of the present invention. For example, the invention can be used for metal evaporation. The method of the southern gloss paper - the touch of the blue towel, as the base ^ winding form t, should be connected, . 'Λ long secret μ base 2G1P, or other base layer such as fabric, by the supply volume 201 is continuously provided. · As indicated by the direction of the arrow in the figure, the base of the paper f can be driven by the group of coatings 214, which is pushed from left to right in the figure. In the process, the coating solution supply is added. Apply the coating solution from the coating solution tank 2 to the surface below the paper substrate. The stomach is coated with the paper substrate coated with the coating solution, and then it is pressed onto the shiny surface to form a press. Fortunately, the 218' is provided here with the luster provided by the gloss supply layer supply 2〇2. Since the gloss provides the layer of the lion system from the downward direction of the paper base, the direction of the downward surface i should be Apply to the coating solution supply roller The coating/grain layer ' on the bottom surface of the substrate 2 (10) is now sandwiched between the paper substrate and the inner surface of the gloss providing layer 202F. The paper substrate 20.1P and the gloss providing layer 2G2F The latter temporary composite layer is marked with 201C in the figure, and then enters the drying and curing device 23〇 for drying and solidification treatment. The function of the dry curing device is to make the coating on the paper substrate p and the gloss providing layer. Move the F between the two to test the fast dry ship secret (four) punch. For this purpose 'dry curing device 230 can be used with any suitable equipment, such as hot air off the ot flow" 'ultraviolet light (uv), Or any device that is based on infrared (IR) to provide the energy required to dry and/or cure the coating solution. The temporary composite layer 2 lc of the coating solution material which has been dried and solidified is removed from the dry olefin curing device 230 and directly enters the cooling device 242 for cooling to facilitate the next step of the treatment. Cooling device 242 can be any suitable device, such as a cooling device that supplies a flow of cool air. The direct use of the cooling device 242 is to adjust the overall temperature of the temporary composite layer 201C to the two structural layers suitable for the composite layer 2〇1: the paper substrate 1273152 201P and the gloss & supply layer 202F, both Separate, but at the same time, the cured coating material layer is completely adhered to the lower surface of the paper substrate 201P. The paper substrate covered with the dry cured coating layer is removed from the figure. After the group 244 is indicated by the reference numeral 251P. The paper substrate 201P and the gloss providing layer 202F are respectively separated from the embossed structure of the temporary composite layer 201C, and the high gloss paper can be simply used: 251 and the gloss providing layer recovery roll 252 are obtained by dragging the respective rolls at an appropriate angle formed by an appropriate relative distance via the assistance of the peeling roller set 244. At this time, the roll is collected on the local glossy paper collecting roll 251. It is a glossy paper 251P whose surface has been covered with a layer of high flatness coating material. 'This high gloss paper 251p taken up by the sleek paper collection roll 251 can be subjected to surface metal such as metal* plating. The appropriate treatment can be used to form a paper having a surface metallic luster for various industrial and commercial uses. These treatments are not for the purpose of the present invention, and are not described in detail herein. In another aspect, the roll 252 is recovered from the gloss providing layer. The collected gloss providing layer 202F' can be reused because it does not have a coating substance remaining on its surface _ : as solved by those skilled in the art (4), the recycled silk provides a layered lion to utilize the whole roll Reinstalled on the gloss supply layer supply roll 2G2, or directly in the manner not shown in the figure, directly to the way the gloss supply layer is supplied to the roll, and reused. This gloss provides a layer for repeated use. There may be a significant benefit of reducing the cost. A partial enlarged view of Figures 2 and 3 shows the formation of a silky surface when a high gloss silk paper is produced in accordance with a preferred embodiment of the present invention. It shows the situation where the paper substrate coated with the coating solution is applied to the shiny surface to the 218-, and the gloss supply layer 2 (4) is combined.

As described in the related description of the process shown in Figure 1, it is sandwiched between the paper substrate 201P and the gloss providing layer. The coating material, that is, the original coating layer 22 which has not been dried and solidified in FIG. 2, can be separated from the shiny surface to form a pressing roller 218, and then enters the drying curing device (230, FIG. D is dried and solidified, and then _ Roller set (244 'where D is stripped) is shown in Figure 3 Show the situation. Fig. 3 is a partially enlarged schematic view showing the original coating layer which is originally sandwiched between the paper substrate 2〇ip and the gloss providing layer 2_ after being pressed in Fig. 2: This day π dry and non-curing treatment [Moxibustion, a cured gloss coating layer 222L has been formed before entering the peeling roller set 244 in the drawing. When the three-laminate structure on the left side of the peeling wheel set 244 in FIG. 3, as the direction indicated by the dotted arrow in the figure, advances from left to right and leaves the peeling roller set 244, they are peeled off each other to form no residual surface. The gloss of the coating material provides a layer 2G2F, and a high gloss paper 251p, which complements the structure. As clearly shown in the detail in Fig. 3, the high gloss paper 251p is based on the original paper substrate 201Ρ, and the lower surface is covered with the cured gloss coating layer 222l, and the glossy surface 251G has a high gloss, that is, The high flatness upper surface from the gloss providing layer 2〇2F. In other words, the high flat surface properties of the gloss providing layer 2〇2F are transferred to the surface of the cured gloss coating layer 222L to form a glossy surface 251G. As described above, the gloss providing layer 2〇2F is provided as a source of a glossy surface, and its surface should not leave any coating material after being peeled off from the cured gloss coating layer 222L. In contrast, the base material of the gloss coating layer 222L, that is, the original coating solution, which adheres to the gloss providing layer 202F after curing, should be selected to be relatively small. In the typical embodiment of the method for producing high-gloss paper for metal vapor deposition of the present invention, the original coating solution as the coating material is preferably used, but not limited to, water-based, solvent-based and uv-curable. Etc. Acrylic solution. Other polymers or copolymers such as styrene and acrylates (p〇iymers οχ* copolymers); methacrylates, vinyi acetate, maleic acid a polymer or copolymer of maleate, acrylonitrile, acryliamide and acrylates; and a thermoplastic or copolymer of methacrylate and ethylene Thermoplastic resins are also suitable.
