Description

  The present invention relates to a coating film structure, a method for producing the same, and a building board. More specifically, the present invention relates to a coating film structure in which a plurality of coating films are laminated, a manufacturing method thereof, and a building board provided with a coating film structure on the surface.

  Conventionally, a decorative building board having full-color ink jet printing on an uneven surface has been proposed, and various ideas have been made to express a sharp design (for example, see Patent Document 1).

  FIG. 4A and FIG. 4B show an example of a building board 100 that is decorated. In the building board 100, the surface of the base material 105 is formed on an uneven surface composed of a concave portion 106 and a convex portion 107. On the uneven surface of the base material 105, a coating film structure 104 composed of a coating film layer 101 and an ink layer 103 is formed. The coating layer 101 is white and is formed on the uneven surface of the substrate 105 over the entire surface. The ink layer 103 is formed on the entire surface of the coating layer 101 by inkjet printing. The ink layer 103 is formed of a low lightness ink layer 111 having a low lightness and a high lightness ink layer 110 having a high lightness. The low lightness ink layer 111 has a lightness lower than that of the high lightness ink layer 110. The low-lightness ink layer 111 is formed at the concave portion corresponding portions (the bottom surface and the side surface of the concave portion 106). The high-lightness ink layer 110 is formed at a portion corresponding to the convex portion (the top surface of the convex portion 107). Then, by forming the low-lightness ink layer 111 and the high-lightness ink layer 110, the darkness of the concave portion 106 and the convex portion 107 is made clear, and the unevenness on the surface of the building board 100 is given sharpness. Trying to improve the appearance.

  Here, the data for inkjet printing is created in accordance with the position of the unevenness of the base material 105 that is the printing object.

JP 2006-88502 A

  However, when a dimensional change occurs in the base material 105, for example, when the concave portion 106a shown in FIG. 5 is formed wider than the other concave portions 106, the low lightness ink layer 111 is formed only in the central portion of the concave portion 106a. Thus, the high brightness ink layer 110 is not formed at both ends of the recess 106a, but a part of the high brightness ink layer 110 covering the top surface of the projection 107 on both sides of the recess 106a also covers the end of the recess 106a. And the low-lightness ink layer 111 do not coincide with the boundary between the concave portion 106a and the top surface of the convex portion 107, and are liable to be displaced in the concave portion 106a. And the external appearance of the coating-film structure 104 was easy to fall by such printing misalignment.

  In addition, as shown in FIG. 6, an ink missing portion 108 may be formed such that the high brightness ink layer 110 is not printed and the coating film layer 101 is exposed, and the appearance of the coating film constituent 104 is likely to deteriorate. there were.

(First embodiment)
[Description of coating composition and building board]
The building board 10 of 1st embodiment is shown by FIG. 1A and 1B. The building board 10 includes a coating film structure 4 and a base material 5. The coating film construct 4 is laminated on the surface of the substrate 5.

  The base material 5 is formed in a plate shape. The base material 5 is formed of an arbitrary material such as a ceramic board (hardened material of a hydraulic material including cement), a plastic board, a wooden board, a metal board, and the like, and has been conventionally used as a building material. It is preferable to form with the material which is. Irregularities are formed on the surface of the substrate 5. The unevenness is formed by a plurality of concave portions 6 and a plurality of convex portions 7, and the concave portions 6 and the convex portions 7 are formed adjacent to each other.

  The coating film construct 4 includes an underlayer 1, a colored layer 2, and an ink layer 3.

  The underlayer 1 is provided in close contact with the entire surface of the substrate 5 on which the irregularities are formed.

  The colored layer 2 is provided in close contact with part of the surface of the underlayer 1. For example, the colored layer 2 is formed on a portion of the surface of the base layer 1 corresponding to the top surface of the convex portion 7 of the base material 5. The colored layer 2 may be formed on the surface of the base layer 1 at portions corresponding to the bottom surface and the side surface of the recess 6 of the base material 5. The colored layer 2 has a color different from that of the underlayer 1. The colored layer 2 preferably has a lighter color than the underlayer 1. In this case, even if the unevenness position of the substrate 5 and the printing pattern of the ink layer 3 are slightly misaligned, it may be difficult to stand out. it can. That is, when the concave portion 6 and the convex portion 7 are separately applied with different colors by ink jet printing or the like, the print data of the concave portion 6 and the print data of the convex portion 7 are separately produced and printed. The printing data of the concave portion 6 and the printing data of the convex portion 7 are created based on the design dimensions of the base material 5. In this method, when the dimension of the actually manufactured base material 5 changes with respect to the dimension of the base material 5 at the time of design, the area of the print data of the concave portion 6 and the convex portion 7 changes the size of the base material 5. Since the pattern boundary (the boundary between the concave portion 6 and the convex portion 7) and the boundary of the print data (the boundary between the print data of the concave portion 6 and the print data of the convex portion 7) do not coincide with each other. May stand out. On the other hand, in this embodiment, as shown in FIG. 1A, the underlayer 1 is formed on the entire surface of the base material 5 and the colored layer 2 is formed on the surface of the underlayer 1 corresponding to the convex portion 7. Thus, the boundary between the concave portion 6 and the convex portion 7 is formed as a boundary 20 with a different color between the underlayer 1 and the colored layer 2. Therefore, the positional deviation between the boundary between the print data of the concave portion 6 and the print data of the convex portion 7 and the boundary between the concave portion 6 and the convex portion 7 are less noticeable.

  The colored layer 2 can be white, for example. The underlayer 1 may be darker than the colored layer 2, for example, black.

  The ink layer 3 is formed including a boundary 20 between the base layer 1 and the colored layer 2. Here, including the boundary 20 between the underlayer 1 and the colored layer 2 means that the boundary 20 is covered with the ink layer 3. Accordingly, the ink layer 3 is formed so as to cover the surface of the underlayer 1 where the colored layer 2 is not formed and the surface of the colored layer 2. The ink layer 3 may be formed so as to cover the entire surface of the underlayer 1 where the colored layer 2 is not formed and the entire surface of the colored layer 2. The ink layer 3 is formed so that the boundary 20 is visible. Accordingly, the ink layer 3 is formed to be transparent or translucent so that the boundary 20 can be seen through. The ink layer 3 may be colored or colorless as long as the boundary 20 can be seen through. Thus, the ink layer 3 is formed including the boundary 20 between the base layer 1 and the colored layer 2, and the ink layer 3 is formed so that the boundary 20 can be visually recognized. Even if the printing pattern of the ink layer 3 is slightly misaligned, it can be made inconspicuous. That is, as described above, when the concave portion 6 and the convex portion 7 are separately applied with different colors by ink jet printing or the like, there is a possibility that the positional deviation of printing is conspicuous. On the other hand, in the present embodiment, as described above, the base layer 1 is formed on the entire surface of the base material 5, and the portion corresponding to the convex portion 7 (corresponding to the top surface of the convex portion 7) of the surface of the base layer 1. In this case, the boundary between the concave portion 6 and the convex portion 7 can be formed as a boundary 20 with a different color between the underlayer 1 and the colored layer 2. Even if it is formed, since the boundary 20 is visible from the outside, even if the boundary of the pattern formed on the ink layer 3 does not coincide with the boundary between the concave portion 6 and the convex portion 7, the base layer 1 and the colored layer 2. Is recognized as the boundary between the concave portion 6 and the convex portion 7, so that the positional deviation is less noticeable.

  Moreover, the coating film structure 4 can suppress the amount of ink used to form the ink layer 3. That is, since the recess 6 is colored before the ink layer 3 is formed, the amount of ink used to fill and color the recess 6 can be reduced, and the ink amount of the design to be colored Therefore, the amount of ink used can be suppressed. Furthermore, since the base of the ink layer 3 is formed with a plurality of colors of the base layer 1 and the colored layer 2 having different colors, the paint film construct 4 has a wider color gamut that can be expressed.

  In the present embodiment, the print pattern corresponding to the unevenness of the base material 5 as the ink layer 3, that is, the case where the concave portion 6 and the convex portion 7 are separately applied with different color patterns, is not limited to this. Even when print data created irrespective of the concave portion 6 and the convex portion 7 is used, the concave portion 6 and the convex portion 7 are formed by the visual recognition of the boundary 20 between the underlayer 1 and the colored layer 2 in different colors. Be recognized. In addition, since different colors of the underlayer 1 and the colored layer 2 and the color of the ink layer 3 appear to be mixed, an expressible color gamut is expanded. Further, the ink can be obtained by forming the base layer 1 having a color that approximates a color frequently used for the color pattern desired to be expressed by the concave portion 6 and the color layer 2 having a color approximate to a color frequently used for the color pattern desired to be expressed by the convex portion 7. Even when the amount of ink used is reduced, the color of the underlying layer 1 and the colored layer 2 itself complements the amount of ink reduced, so that the amount of expensive ink used can be suppressed.

[Description of Manufacturing Method of Coating Composition]
When manufacturing the coating-film structure 4 like 1st embodiment, it carries out as follows.

  First, the process of forming the base layer 1 on the surface of the base material 5 is performed. The underlayer 1 can be formed, for example, by applying an enamel paint by spraying and drying and curing. Next, the process of forming the colored layer 2 which exhibits a color different from the base layer 1 in a part of surface of the base layer 1 is performed.

  For example, the colored layer 2 is formed on a portion of the surface of the base layer 1 corresponding to the top surface of the convex portion 7 of the base material 5. The colored layer 2 may be formed on the surface of the base layer 1 at portions corresponding to the bottom surface and the side surface of the recess 6 of the base material 5. The colored layer 2 can be formed, for example, by applying an enamel paint with a roll and drying and curing it. Next, a step of forming an ink layer 3 that includes at least the boundary 20 between the base layer 1 and the colored layer 2 and is visible is possible. In this case, the ink layer 3 is formed so as to cover the surface of the base layer 1 where the colored layer 2 is not formed and the surface of the colored layer 2. Further, the ink layer 3 may be formed so as to cover the entire surface of the underlayer 1 where the colored layer 2 is not formed and the entire surface of the colored layer 2. The ink layer 3 is preferably formed by ink jet printing using CMYK ink (cyan ink, magenta ink, yellow ink, black ink), whereby the ink layer 3 can be easily formed.

  By forming the coating film structure 4 in this manner, the coating film structure 4 having the above effects can be easily created.

(Second embodiment)
[Description of coating composition and building board]
The building board 10 of 2nd embodiment is shown by FIG. 2A and 2B. The building board 10 includes a coating film structure 4 and a base material 5. The coating film construct 4 is laminated on the surface of the substrate 5.

  The base material 5 is formed in a plate shape. The base material 5 is formed of an arbitrary material such as a ceramic board (hardened material of a hydraulic material including cement), a plastic board, a wooden board, a metal board, and the like, and has been conventionally used as a building material. It is preferable to form with the material which is. Irregularities are formed on the surface of the substrate 5. The unevenness is formed by a plurality of concave portions 6 and a plurality of convex portions 7, and the concave portions 6 and the convex portions 7 are formed adjacent to each other.

  The coating film construct 4 includes an underlayer 1, a colored layer 2, and an ink layer 3.

  The underlayer 1 is provided in close contact with the entire surface of the substrate 5 on which the irregularities are formed.

  The colored layer 2 is provided in close contact with part of the surface of the underlayer 1. For example, the colored layer 2 is formed on the surface of the base layer 1 at portions corresponding to the bottom surface and the side surface of the recess 6 of the substrate 5. The colored layer 2 and the base layer 1 form a pattern corresponding to the unevenness. Further, the colored layer 2 may be formed on a portion of the surface of the base layer 1 corresponding to the top surface of the convex portion 7 of the base material 5. The colored layer 2 has a color different from that of the underlayer 1. As shown in FIG. 2, when the colored layer 2 is formed at locations corresponding to the bottom and side surfaces of the recess 6 of the substrate 5, the colored layer 2 preferably exhibits a darker color than the underlayer 1. . In this case, even if the uneven position of the base material 5 and the print pattern of the ink layer 3 are slightly misaligned, it can be made inconspicuous. That is, when the concave portion 6 and the convex portion 7 are separately applied with different colors by ink jet printing or the like, the print data of the concave portion 6 and the print data of the convex portion 7 are separately produced and printed. The printing data of the concave portion 6 and the printing data of the convex portion 7 are created based on the design dimensions of the base material 5. In this method, when the dimension of the actually manufactured base material 5 changes with respect to the dimension of the base material 5 at the time of design, the area of the print data of the concave portion 6 and the convex portion 7 changes the size of the base material 5. Since the pattern boundary (the boundary between the concave portion 6 and the convex portion 7) and the boundary of the print data (the boundary between the print data of the concave portion 6 and the print data of the convex portion 7) do not coincide with each other. May stand out. In contrast, in the present embodiment, as shown in FIG. 2A, the underlayer 1 is formed on the entire surface of the base material 5 and the corresponding portion of the surface of the underlayer 1 corresponding to the recess 6 (corresponding to the bottom surface and the side surface of the recess 6 When the colored layer 2 is formed at a location where the underlayer 1 and the colored layer 2 are formed, the boundary between the concave portion 6 and the convex portion 7 is formed as a boundary 20 with a different color. Therefore, the positional deviation between the boundary between the print data of the concave portion 6 and the print data of the convex portion 7 and the boundary between the concave portion 6 and the convex portion 7 are less noticeable. For example, when the colored layer 2 is formed at a location corresponding to the recess 6 as shown in FIG. 2A, the colored layer 2 can be black. The underlayer 1 may be lighter than the colored layer 2, for example, white.

  The ink layer 3 includes a first ink layer 31 and a second ink layer 32. The first ink layer 31 and the second ink layer 32 are formed on the pattern formed by the base layer 1 and the colored layer 2 to form a finer pattern of the pattern. The first ink layer 31 is formed on the non-colored surface 11 excluding the portion of the surface of the base layer 1 where the colored layer 2 is formed. The second ink layer 32 is formed on the surface of the colored layer 2. Note that the first ink layer 31 does not have to completely coincide with the non-colored surface 11, and a part of the first ink layer 31 may be formed to overlap the surface of the colored layer 2. Further, the second ink layer 32 does not need to be completely coincident with the colored layer 2, and a part of the second ink layer 32 may be formed on the non-colored surface 11. The ink layer 3 is more clearly visible than the boundary between the print data of the concave portion 6 and the print data of the convex portion 7 where the boundary 20 of the base layer 1 and the colored layer 2 in different colors is formed in the ink layer 3. It is formed so that it can be.

  Even if the coating layer structure 4 as described above causes printing misalignment between the unevenness position of the base material 5 and the first ink layer 31 and the second ink layer 32 due to the base layer 1 and the colored layer 2, It can be inconspicuous. That is, as described above, when the concave portion 6 and the convex portion 7 are separately applied with different colors by ink jet printing or the like, there is a possibility that the positional deviation of printing is conspicuous. On the other hand, in the present embodiment, as described above, by forming the base layer 1 on the entire surface of the base material 5 and forming the colored layer 2 in the portion corresponding to the recess 6 in the surface of the base layer 1, The boundary between the concave portion 6 and the convex portion 7 can be formed as a boundary 20 with a different color between the underlayer 1 and the colored layer 2, and even if the ink layer 3 is formed, the boundary 20 is the ink layer 3. Since the print data of the concave portion 6 and the print data of the convex portion 7 are visible more clearly than the boundary, the positional deviation of the pattern boundary formed in the ink layer 3 is less noticeable.

  Further, as shown in FIG. 2C, when the base material 5 is changed from the dimension at the time of design and some of the recesses 6 a are formed wider than the other recesses 6, the second ink layer 32 of the ink layer 3 is formed. The first ink layer 31 is formed only at the central portion of the recess 6a and at both ends of the recess 6a. However, even in this case, as shown in FIG. 2D, the boundary between the concave portion 6 and the convex portion 7 can be formed as a boundary 20 with a different color between the underlayer 1 and the colored layer 2, and the ink layer 3 is further formed. Even though the boundary 20 is visible more clearly than the boundary 21 between the print data of the concave portion 6 formed on the ink layer 3 and the print data of the convex portion 7, the boundary 20 of the concave portion 6 formed on the ink layer 3 is visible. The positional deviation of the boundary 21 between the print data and the print data of the convex portion 7 is less noticeable.

  Moreover, the coating-film structure body 4 can suppress the usage-amount of the ink which forms the ink layer 3, similarly to 1st embodiment. Furthermore, since the coating layer structure 4 is formed with a plurality of colors of the base layer 1 and the colored layer 2 having different colors as the base of the ink layer 3 as in the first embodiment, a color that can be expressed. The area expands.

[Description of Manufacturing Method of Coating Composition]
When manufacturing the coating-film structure 4 like 2nd embodiment, it carries out as follows.

  First, the process of forming the base layer 1 on the surface of the base material 5 is performed. The underlayer 1 can be formed, for example, by applying an enamel paint by spraying and drying and curing. Next, the process of forming the colored layer 2 which exhibits a color different from the base layer 1 in a part of surface of the base layer 1 is performed. The colored layer 2 is formed on portions of the surface of the base layer 1 corresponding to the recesses 6 of the substrate 5 (the bottom surface and side surfaces of the recesses 6). The colored layer 2 may be formed on a portion corresponding to the convex portion 7 of the base material 5 (the top surface of the convex portion 7) in the surface of the base layer 1 other than the portion corresponding to the concave portion 6. The colored layer 2 can be formed, for example, by applying an enamel paint by spraying and drying and curing. Here, when the colored layer 2 is formed on portions corresponding to the bottom surface and the side surface of the recess 6 of the base material 5, for example, a relatively fluid paint is applied to the surface of the base layer 1. Thereby, since the coating material applied to the portion corresponding to the top surface of the convex portion 7 on the surface of the base layer 1 flows into the concave portion 6, the colored layer 2 is formed at least on the portions corresponding to the bottom surface and the side surface of the concave portion 6. The Next, the first ink layer 31 is formed on the non-colored surface 11 excluding the portion of the surface of the underlayer 1 where the colored layer 2 is formed, and the second ink layer 32 is formed on the surface of the colored layer 2 The process to do is performed. The ink layer 3 composed of the first ink layer 31 and the second ink layer 32 is preferably formed by inkjet printing using CMYK ink (cyan ink, magenta ink, yellow ink, black ink). The ink layer 3 can be easily formed.

By forming the coating film structure 4 in this manner, the coating film structure 4 having the above effects can be easily created.
