Description

  The present invention relates to a cracked pattern attaching method used for, for example, advertising, decoration, interior, exterior, and the like, and a cracked pattern attached body.

  Conventionally, as the above-described method for providing a crack pattern, for example, a cracked film forming polymer composition is directly applied to the surface of a supporting substrate to form a cracked film, or the film surface is covered with a substance different from the film forming component. There are emulsion compositions for film formation of Patent Document 1 that are cracked integrally with the coating film, coating films obtained from the composition, production methods thereof, and surface treatment methods using these.

However, the above-mentioned Patent Document 1 forms a cracked film by directly applying the film-forming polymer composition to the surface of the supporting substrate, but only forms a crack on the material covering the film surface of the film-forming polymer composition. There is no disclosure of structure and idea, and cracks cannot be formed only in the material covering the coating surface. In addition, when changing the size of cracks formed in the coating, the content of the component contained in the polymer composition for coating formation must be changed or the type of the component must be changed. Adjustment and selection of the type are difficult, and there is a problem that it takes time and effort to form a crack of a desired size on the film.

  In view of the above problems, the present invention forms an inner coating layer and an outer coating layer having different characteristics on the surface of the patterned body, so that a desired cracked pattern is formed on the outer side according to the characteristics of the inner coating layer and the outer coating layer. It is an object of the present invention to provide a cracked pattern attaching method that can appear in a coating layer and a cracked pattern attached body.

  According to the present invention, an inner coating layer that generates cracks only in the outer coating layer is formed on the surface of the patterned body, and an outer surface that generates cracks of a size corresponding to the inner coating layer is formed on the surface of the inner coating layer. It is a method for providing a crack pattern in which a coating layer is formed and a crack is generated only in the outer coating layer due to a difference in characteristics between the inner coating layer and the outer coating layer. Further, the inner coating layer is formed by forming an inner coating layer for generating cracks only on the outer coating layer and an outer coating layer for generating cracks of a size corresponding to the inner coating layer on the surface of the patterned body. And a structure with a crack pattern in which a crack is generated only in the outer coating layer due to a difference in characteristics between the outer coating layer and the outer coating layer.

  The above-mentioned patterned body can be made of a light-transmitting material such as plastic or glass, or a non-light-transmitting material such as ceramics, concrete, metal, wood, or fabric, but can recognize cracked patterns. If so, it can be made of a material that is translucent or opaque and colored in a desired color. Examples of the plastic include polyethylene terephthalate (PET), polyethylene, polypropylene, polyester, acrylic, nylon, vinyl chloride, and polycarbonate.

  Further, the inner coating layer and the outer coating layer can be formed of a coating forming liquid such as ink, paint, solvent, solution, or the like having such a characteristic that only the outer coating layer is cracked. Further, the inner coating layer can be composed of a coating forming liquid having the following characteristics that cause cracks only in the outer coating layer. Further, the outer coating layer can be composed of a coating forming liquid having the following characteristics that generate cracks due to the characteristics of the inner coating layer. Examples of the above characteristics include the viscosity and concentration of the film forming liquid, the volatilization rate of the volatile component (diluent), the drying rate, the curing rate, and the like.

  That is, an inner coating layer made of a film forming liquid (for example, ink or solvent) having a characteristic that causes cracks only in the outer coating layer is formed on the surface of the patterned structure by screen printing, or the inner coating layer On the surface, the outer coating layer consisting of a coating forming solution that generates cracks due to the properties of the inner coating layer is formed by screen printing, etc., so that the viscosity and concentration of the coating forming solution, the volatilization rate of volatile components, and drying Due to the difference in the properties of the inner and outer coating layers, such as the difference in speed, a crack of the desired size is generated only in the outer coating layer according to the characteristics of the inner and outer coating layers, and the outer coating layer A crack pattern appears on almost the whole (or part) of the layer.

  As an embodiment, the size of a crack generated in the outer coating layer can be provided so as to be changeable according to the thickness or the number of layers of at least one of the inner coating layer and the outer coating layer. That is, if the thickness of the inner coating layer is reduced or the number of layers is reduced, the cracks generated in the outer coating layer increase, and if the thickness of the inner coating layer is increased or the number of layers is increased, the cracks generated in the outer coating layer. Therefore, the roughness or density of the crack pattern appearing on the outer coating layer can be arbitrarily changed by merely changing the thickness or the number of layers of at least one of the inner coating layer and the outer coating layer.

  The inner coating layer and the outer coating layer can be formed on both the front and back surfaces of the patterned body. That is, cracks having a size corresponding to the thickness or number of layers of the inner coating layer are generated in the outer coating layers on both the front and back surfaces.

  Further, at least one of the patterned body, the inner coating layer, and the outer coating layer can be colored in a desired color. That is, through the cracks formed in the outer coating layer, for example, the patterned object and the inner coating layer colored in a desired color such as black, red, yellow, green, and blue are exposed to a visible state, and the color scheme thereof To reveal a colorful cracked pattern. Alternatively, only the surface of the patterned body may be colored in a desired color.

  According to the present invention, the inner coating layer and the outer coating layer having different characteristics are formed on the surface of the patterned mounting body constituting the cracked patterned mounting body, and desired depending on the characteristics of the inner coating layer and the outer coating layer. Since a crack of a size is generated in the outer coating layer, a desired crack pattern can be revealed in the outer coating layer. Also, by changing the thickness or number of layers of at least one of the inner coating layer and the outer coating layer, the roughness and density of the cracked pattern that appears on the outer coating layer can be changed according to the purpose, application, location, etc. Can be arbitrarily changed, and a cracked pattern having a desired roughness and density can be obtained.

  According to the present invention, a desired crack pattern can appear on the outer coating layer according to the characteristics of the inner coating layer and the outer coating layer. This was realized by forming an outer coating layer.

An embodiment of the present invention will be described below in detail with reference to the drawings.
The drawings show a crack pattern attaching method and a cracked pattern attaching body capable of revealing a desired crack pattern on the outer coating layer. In FIGS. 1 and 2, the crack pattern attaching method of the present invention is In the case where cracks 5 (or cracks) are attached only to the outer coating layer 4 constituting the cracked pattern attachment body 1 of one embodiment, for example, a synthetic resin plate having inflexible hardness and translucency, flexibility and transparency Formation of a film having such a characteristic that only the outer film layer 4 generates cracks 5 ... on substantially the entire surface (or a part) of the patterned structure 2 constituted by any one of the synthetic resin sheets having light properties, etc. A liquid (for example, ink or solvent) is screen-printed to a substantially uniform thickness, and the inner coating layer 3 is formed as a single layer so that the substantially entire surface of the patterned body 2 is covered.

  Next, the inner coating layer 3 is dried until the outer coating layer 4 is allowed to be screen-printed by the outer coating layer 4, or after the outer coating layer 4 is dried to a freshly dried state allowing the screen printing of the outer coating layer 4. A film-forming liquid (for example, ink or solvent) that generates cracks 5 due to the characteristics of the inner coating layer 3 is screen-printed on substantially the entire surface (or a part) of the plate 3 to a substantially uniform thickness. The outer coating layer 4 is formed as a single layer so that substantially the entire surface of the inner coating layer 3 is covered. Further, if the conditions or elements that cause the cracks 5 are satisfied, it is possible to form a plurality of outer coating layers 4.

  Next, in the drying process of the inner coating layer 3 and the outer coating layer 4 (for example, the diluting liquid contained in the coating forming solution volatilizes), the characteristics of the inner coating layer 3 and the outer coating layer 4 (for example, viscosity and concentration, Due to the difference in volatilization rate, drying rate, curing rate, etc. of the volatile components, nonuniform cracks 5 depending on the thickness or the number of layers of the inner coating layer 3 are substantially evenly distributed over almost the entire outer coating layer 4. The crack pattern 6A (or crack pattern) appears on substantially the entire surface (or part) of the outer coating layer 4. In this case, since the inner coating layer 3 is a single layer, the crack pattern 6A having the roughness and density also shown in FIG. 3 appears on substantially the entire outer coating layer 4.

  Further, after drying the inner coating layer 3 formed on the surface of the textured body 2 to a state in which screen printing of the coating forming solution constituting the outer coating layer 4 is allowed, the coating forming solution for the outer coating layer 4 Can be screen-printed on substantially the entire surface of the previously dried inner coating layer 3 to form the outer coating layer 4 in which cracks 5.

  As described above, the inner coating layer 3 and the outer coating layer 4 having different characteristics are formed on the surface of the patterned assembly 2 constituting the cracked patterned assembly 1, and the characteristics of the inner coating layer 3 and the outer coating layer 4, According to the thickness and the number of layers, cracks 5... Of a desired size are generated in the outer coating layer 4, so that the crack pattern 6 </ b> A can appear on substantially the whole (or a part) of the outer coating layer 4. . Further, the roughness and density of the cracked pattern 6A appearing on the outer coating layer 4 can be determined by simply changing the thickness or the number of layers of at least one of the inner coating layer 3 and the outer coating layer 4, and the purpose and use thereof. It can be arbitrarily changed according to the location and the like, and crack patterns 6A, 6B, 6C having a desired roughness and density can be obtained.

  Further, if at least one of the patterned body 2, the inner coating layer 3, and the outer coating layer 4 is colored in a desired color such as black, red, yellow, green, blue, etc., it is formed on the outer coating layer 4. Since the pattern-attached body 2 and the inner coating layer 3 colored in a desired color are exposed through the cracks 5... Are vividly colored by the color arrangement of the inner coating layer 3 and the outer coating layer 4. Cracked patterns 6A, 6B and 6C can be revealed. Alternatively, only the surface of the patterned body 2 may be colored in a desired color.

  Further, if a part or the whole of the patterned body 2 is formed of a transparent or translucent material having translucency, cracked patterns 6A, 6B, 6C appearing on the surface or both front and back surfaces of the patterned body 2 Can be seen through or seen from both the front and back surfaces of the patterned body 2.

  The cracked structure 1 according to the second embodiment shown in FIG. 4 shows an example in which the inner coating layer 3 is formed so that the number of layers of the inner coating layer 3 is larger than that of the inner coating layer 3 of the first embodiment, for example, the first embodiment. The inner coating layer 3 is formed in two layers, and a crack pattern 6B (see FIG. 9 or FIG. 10) smaller than the first embodiment corresponding to the thickness of the two inner coating layers 3 and 3 is formed on the outer coating layer. Since it appears only in 4, it is possible to achieve substantially the same operation and effect as the first embodiment.

  The cracked structure-attached body 1 of the third embodiment shown in FIG. 5 shows an example in which the inner coating layer 3 is formed so that the number of layers is larger than that of the inner coating layer 3 of the second embodiment. The inner coating layer 3 of the example is formed in three layers (or three or more layers), and a crack pattern 6C (see FIG. 10) smaller than the second embodiment corresponding to the thickness of the three inner coating layers 3. Since it appears only on the outer coating layer 4, it is possible to achieve substantially the same operations and effects as in the first embodiment.

  As described above, when the number of the inner coating layer 3 is reduced, the cracks 5 generated in the outer coating layer 4 are increased, and when the number of the inner coating layer 3 is increased, the cracks 5 generated in the outer coating layer 4 are increased. 9 and 10, the roughness and density of the cracked patterns 6A, 6B, and 6C appearing on the outer coating layer 5 can be arbitrarily set by simply changing the number of inner coating layers 3 as shown in FIGS. Can be changed.

  The cracked structure-attached body 1 of the fourth embodiment shown in FIG. 6 shows an example in which the thickness of the inner coating layer 3 is formed so as to be thinner than the inner coating layer 3 of the first embodiment. As the thickness of the inner coating layer 3 of the embodiment is made thinner, the cracks 5... Generated in the outer coating layer 4 become larger than those of the first embodiment, and the first embodiment according to the thickness of the inner coating layer 3. Since the larger cracked pattern 6A (see FIG. 9 or FIG. 10) appears only on the outer coating layer 4, it is possible to achieve substantially the same operations and effects as in the first embodiment.

  The cracked structure-attached body 1 of the fifth embodiment shown in FIG. 7 shows an example in which the thickness of the inner coating layer 3 is formed so as to be thicker than the inner coating layer 3 of the first embodiment. The inner coating layer 3 of the example is formed to be approximately equal to the thickness of the two inner coating layers 3 formed, and is substantially equivalent to the third embodiment according to the thickness of the inner coating layers 3 and 3 for two layers or more than the fourth embodiment. Since the small crack pattern 6B (see FIG. 10) appears only on the outer coating layer 4, it is possible to achieve substantially the same operations and effects as in the first embodiment.

  8 shows an example in which the inner coating layer 3 is formed such that the inner coating layer 3 is thicker than the inner coating layer 3 of the fifth embodiment. The inner coating layer 3 of the example is formed substantially equivalent to the thickness of the three layers (or three or more layers printed), and is substantially equivalent to the third embodiment according to the thickness of the inner coating layer 3 for three layers or Since the crack pattern 6C (see FIG. 10) smaller than that of the fifth embodiment appears only on the outer coating layer 4, it is possible to achieve substantially the same operations and effects as those of the first embodiment.

  As described above, when the inner coating layer 3 is thinned, the cracks 5 generated in the outer coating layer 4 increase, and when the inner coating layer 3 is thickened, the cracks 5 generated in the outer coating layer 4. 9 and 10, the roughness and density of the cracked patterns 6A, 6B, and 6C appearing on the outer coating layer 5 can be arbitrarily set by simply changing the thickness of the inner coating layer 3 as shown in FIGS. Can be changed.

  The cracked pattern-attached body 1 of the seventh embodiment shown in FIG. 11 shows an example in which cracks 5... Are formed on the outer coating layers 4, 4 formed on the entire front and back both surfaces (or a part) of the pattern-attached body 2. As shown in the first to sixth embodiments, crack patterns 6A, 6B, 6C (see FIG. 10) corresponding to the thickness or the number of layers of the inner coating layer 3 appear only on the outer coating layers 4, 4 on both sides. Since it is made to come out, there can exist an effect | action and effect substantially equivalent to 1st Example.

  In addition, this invention is not limited only to the structure of the above-mentioned Example. For example, the thickness or number of layers of the inner coating layer 3 is formed so that the thickness gradually increases from the rough region to the dense region of the cracked pattern 6A set on the surface of the textured structure 2 and the number of layers increases. The roughness or density of the crack pattern 6A appearing on the coating layer 4 is changed from the thin area or the small number of layers of the inner coating layer 3 corresponding to the rough area of the crack pattern 6A to the dense area of the crack pattern 6A. It can also appear in a gradation that gradually decreases toward a thicker area or a larger number of layers of the corresponding inner coating layer 3.

  As another method for revealing the above cracked patterns 6A, 6B, 6C, for example, when the viscosity of the film forming liquid constituting the outer coating layer 4 is higher than the viscosity of the film forming liquid constituting the inner coating layer 3, Crack patterns 6A, 6B, 6C are easy to appear and the pattern becomes large. Further, if the viscosity of the film forming liquid constituting the outer coating layer 4 is lowered, the cracked patterns 6A, 6B, 6C are difficult to appear and the pattern becomes smaller, so that at least one of the inner coating layer 3 and the outer coating layer 4 is coated. The appearance of the cracked patterns 6A, 6B, 6C can also be adjusted by changing the viscosity of the forming liquid.

  In addition, if the patterned body 2 is made of a material that can easily absorb at least one of the inner coating layer 3 and the outer coating layer 4 (solvent) (for example, vinyl chloride or polycarbonate), the crack pattern 6A, 6B. , 6C is easy to appear and the pattern becomes large. Further, if the film forming liquid (solvent) is difficult to absorb (for example, acrylic or PET), the cracked patterns 6A, 6B, and 6C are difficult to appear and the pattern becomes small. The appearance of the crack patterns 6A, 6B, 6C can also be adjusted.
