Most of them will have pictures to indicate seller information, content and other marketing information. Wherein when the disposable container is filled with hot drinks, the container preferably has a moderate heat insulation effect, and the side causes the material to be inspected (4) to cause discomfort or even burns. In order to improve the problem, the foamed layer is additionally formed on the surface of the cup of the disposable container, so as to moderately isolate the temperature conduction. For example, the applicant applies the application No. 94143974 and the %%% patent application, and the I7 discloses a heat insulating container which directly forms a foam layer on the surface of the grain. Further, as disclosed in U.S. Patent No. 5,952, 068, the adhesive is applied to the surface of the container, and then the cloth is composed of an insulating layer composed of hollow particles. In the previous patent, although these containers have a heat-insulating effect, how to use the container information becomes a new topic. For example, in the patents 94143974 # and 2,426, it is disclosed that a color bribe can be added to the composite coating to recoat the surface, or to re-color after the Wei. However, the straight 201202058 is connected to the uneven surface of the foamed shirt to print, and can not achieve the excellent printing quality, so that the printed graphics have unintended effects such as burrs or fogging, and if the graphic is only printed on When the foam layer is flat, the image can only produce a two-dimensional visual perception, and the advantages of the three-dimensional foam layer cannot be highlighted. In addition, in the lion's patent, it can also add impurities to the insulation layer or print on the surface to form the label (labeI _). However, the county reveals how to form a better printing effect on the fresh n surface. Taking _ will also have the problems that the above-mentioned objects are not sophisticated, and the advantages of the method are obvious. Again, please refer to Figures 6 and 7. When the technique is printed on the foam layer, the foam layer 3 has a significant difference in height from the surface of the substrate, which tends to cause the side edge 5 of the foam layer 3 to be affected. Correction, as shown in Figure 8, when the gap between the two adjacent foam layers is to be colored, the same as the above-mentioned foamed layer 3 has been expanded to cause a hindrance, resulting in the lack of precision coating of the hollowed out portion. . The printing of the surface does not achieve the desired effect, so it is the advantage of the image and highlights the information of the graphic, which is the primary point of the invention in view of how to directly exert the foam layer directly on the foam layer table. SUMMARY OF THE INVENTION [Coloration] In order to provide a precise form on a substrate, the manufacturing method provided for achieving the above object includes: Mixing: forming a liquid adhesive and a hot-cell polymer inner coating point solvent 201202058 The heat-expanded particle powder is stirred and mixed to form a composite coating; coating the composite coating · directly coating the composite coating on the outer surface of the substrate to form a composite coating · and the amount of coating is at least __ uncoated a hollow portion of the composite coating; coating a colorant. coating a colorant on at least a portion of the void portion to form a colorant layer, and

Before the coating layer is foamed, the coloring material is coated. At this time, the difference between the surface of the composite S coating layer and the surface of the substrate is not obvious, so the coloring material can be more accurately and purely coated on the surface of the crucible and the composite layer. Forming a continuous graphic to improve the (four) color and cloth process is prone to problems such as discontinuity of the image and difficulty in coating to the narrow hollow portion. [Embodiment] First, referring to Figure b, in the present invention, a substrate surface is formed. The method of the color layer and the foam layer comprises the following steps: a colorant mixture. The _ adhesive is mixed with the heat-polymer inner coating _·point solvent powder to form a composite coating; In the case of rare, esthetic, argon, and argon, the liquid binder may be aqueous or oily; coating the composite coating: directly coating the composite coating on the outer surface of the substrate to form 201202058 - a composite coating layer, a composite coating layer and a perimeter The hollow portion of the composite coating is not coated; wherein the substrate may be a material such as paper, guinea, styrofoam, etc. and the substrate may be used as a container or a container semi-finished product that has not been formed, for example, paper or Plastic cups, bowls, plates or other containers made of this material, and the above-mentioned semi-finished products are, for example, (iv) continuous paper cut into paper cups; and the above method of coating composite coatings Roller, spray, dipping, printing, airknife, extrusion, doctor blade or other suitable means; coating color: coating at least part of the hollow portion to form a color layer Preferably, the foam layer is also coated with a colorant layer. For example, as shown in Fig. 3A, a continuous color layer 20' is applied to the composite coating layer 1 and the hollow portion. The indicator is applied to the narrow coating layer of the two adjacent composite coating layers. Since the height difference between the composite coating layer 1G and the surface of the substrate is not obvious, the color layer 2Q can be easily and accurately Coated on the surface of the hollow and composite coating Foaming: at a foaming temperature higher than that of the heat-expanded particle powder, the composite coating layer is produced on the surface of the substrate. _, (10) into a foamed layer having a hollow portion, wherein the above is still hot The foaming temperature of the foamed particle powder varies with the material used, but the thickness of the hair ride formed at the Wei temperature should be at least twice the thickness of the original composite paint coating, and the multiple is larger. The better the heat insulation effect, the more obvious the three-dimensional effect produced by the combination. Referring to FIG. 2B and FIG. 3B, after the foam layer 30 is expanded, the toner layer 2 will be erected together, 6 201202058 The side edge 31 of the foamed layer 3G can still be covered by the color layer 2G, so that a continuous graphic can be presented; and FIG. 4B shows the color layer of the composite coating layer 1 of FIG. 4A after being foamed. 2G can still be precisely formed in the narrow gap between the foam layers. Wherein, between the step of coating the composite coating and the foaming step, it may further comprise a drying step of "drying" at a temperature lower than the foaming temperature of the heat-recording powder. The complex sigma paint is dry-bonded to the surface of the substrate, and forms a non-sticky surface of the surface of the substrate, which is used to make the inventory of the un-foamed half-filled mouth. For the consideration. More specifically, the drying step is between the coating color step foaming surface or between the coating of the composite coating step and the coating color step. According to the present invention, before the foaming of the composite coating layer, that is, the coloring material is pre-coated, the coloring material layer can be accurately applied to the surface of the substrate and the composite coating layer, and even after the composite coating layer is foamed, the foam is formed. The side of the layer can still be covered by the color material to form a continuous, shell-shaped graphic 'to improve the conventional skills directly printed on the foam layer, and the formation is not easy and the lack of graphic continuity. In addition, the reason why the invention directly prints the graphic on the hollow portion is that the partial pattern material is a temperature sensitive coating which can react to the temperature, and if the temperature sensitive paint is printed on the foam layer, the corresponding temperature is lost. However, if the sensation paint is printed in the hollow portion, the temperature in the container can be directly sensed to produce a corresponding color change, thereby indicating the temperature of the contents and avoiding the user's holding. The foaming layer has an insulating effect, and the temperature of the containing material is not noticed to cause problems such as the hot stamp 201202058. Also, as shown in FIG. 5, the cup is taken as an example, and includes a crotch portion 4 surrounded by a base material and a bottom plate disposed at the bottom end of the crotch portion 4, and the outer periphery of the same portion 4 in the month. The edge is formed with a foam layer 30, which further includes a hollow portion 2, in which the graphic is printed in the hollow portion 2, and the graphic and the outer portion of the hollow portion 2 correspond to each other, so that the hollow portion 2 can be The graphic is more conspicuous, reaching the goal of attracting attention.
