Definitions

  • the present invention relates to a decorative material used to provide an aesthetic effect on the surface of the interior and/or exterior of a building, joinery, furniture, etc.
  • the present invention relates to a decorative material which provides a three-dimensional impression of recesses and protrusions by means of difference in the level of luster on the surface.
  • the above-mentioned method is implemented, for example, by forming a synthetic resin paint layer, from a transparent or semi-transparent synthetic resin paint layer having a lower level of luster, over the entire surface of a substrate whereon an appropriate design including a recess pattern is printed, then forming a transparent or semi-transparent synthetic resin paint having a higher level of luster on a portion of the surface of the synthetic resin paint layer except for the portion where the recess pattern is formed.
  • a synthetic resin paint layer from a transparent or semi-transparent synthetic resin paint layer having a lower level of luster
  • This method enables the rendering of a three-dimensional impression of recesses and protrusions to any substrate simply by preparing two kinds of paints having different luster levels, without using any special chemical.
  • the layers having different luster levels can be formed by a common printing method such as gravure printing after forming the design pattern, no special facility is required so that the process can be carried out with high productivity and matching with the design pattern can be easily achieved.
  • the paint layer can be far thinner than the height difference between the recesses and protrusions to be represented, consumption of the resin can be decreased and higher flexibility is achieved so that a decorative material having an excellent property on bending processing can be easily provided.
  • the decorative material does not have significant surface irregularities, there is such an advantage that stains do not accumulate in recesses.
  • a mechanical embossing method for example, is capable of representing the configuration of the recesses and protrusions such as vessels of natural wood accurately including the sectional configuration.
  • surface luster is provided in two levels and therefore recesses and protrusions that can be represented are also provided in two levels.
  • this method is not capable of representing the configuration of recesses and protrusions having slopes where depth (height) changes continuously as in the case of vessels of natural wood.
  • the present invention has been devised to solve the problems described above, with an obj ect of providing a decorative material that represents a three-dimensional expression of recesses and protrusions by means of difference in the state of luster of the surface, and also represents an improved three-dimensional impression at lower cost without requiring a complicated structure and a complicated manufacturing method.

  • the first luster control layer and the second luster control layer that are controlled to have different states of luster
  • stepwise gradation of the state of luster is provided by the gradation region. It becomes more effective by providing the gradation region at the surface side that exerts a large visual influence. Since gradation is not provided up to a location corresponding to 20% of the thickness of the second luster control layer from the interface of the first luster control layer side to the surface side, cost required to provide the gradation region can be reduced.
  • the decorative material has a surface pattern formed on the first luster control layer directly above the design pattern.
  • Forming the surface pattern on the decorative material of the present invention enables the provision of a design that is recognized as a color pattern, independent from the recesses and protrusions provided in the gradation region.
  • the gradation region of the second luster control layer is provided within a range from a location corresponding to 20% of the thickness of the second luster control layer to the surface side, from the interface of the first luster control layer side to the surface side, a three-dimensional impression can be further improved by exerting stepwise degradation of the state of luster at lower cost without requiring a complicated structure and a complicated manufacturing method.
