Definitions

  • the present invention relates to a decorative member used in an emblem and the like and a manufacturing method thereof.
  • a radio wave transmission cover for a vehicle is generally provided with a decorative layer for displaying various designs.
  • the decorative layer is a relative thin layer formed by metal deposition, film transfer and the like.
  • the radio wave transmission cover is mainly configured with a transparent resin layer of a front side and a base layer of a rear side while interposing the decorative layer between the transparent resin layer and the base layer.
  • the radio wave transmission cover is formed to have a uniform thickness such that transmission/reception of millimeter waves is not affected.
  • a rear surface of the transparent resin layer is employed as an uneven surface having a general part and a concave part recessed with respect to the general part, a blackened print layer is formed in the general part, and then an indium layer is formed on the entire of the uneven surface by a vacuum deposition method as disclosed in JP-A-2009-17125.
  • the indium layer covers the entire of the uneven surface of the transparent resin layer.
  • Indium has a radio wave transmission characteristic, but when the entire surface of the transparent resin layer is covered with the indium, since the attenuation and the phase difference of radio waves of the radio wave transmission cover become large, radio wave transmission performance is reduced.
  • indium printing method a screen printing method, a hot stamping method and the like are considered.
  • the screen printing method is a method in which ink is pushed out from a screen mesh and is printed.
  • the boundary of a print part is shifted from the boundary part of a concave part and a convex part. Since the boundary line of characters and figures of the concave part or the convex part is not clear, appearance becomes worse.
  • the hot stamping method is a method in which a transfer film having a sheet printed with the indium layer is arranged on the uneven surface of the transparent resin layer, and the transfer sheet is pressed to the uneven surface by using a hot stamp while heating it, so that the indium layer is transferred to the uneven surface.
  • a transfer error such as non-attachment of the indium layer on the sheet to the uneven surface.
  • the present invention has been made to solve the above-described problem, and an object of the present invention is to provide a decorative member capable of accurately forming a design on an uneven surface of a transparent resin layer and a manufacturing method thereof.
  • a manufacturing method of a decorative member including: preparing a transparent resin layer provided on a rear surface thereof with a general portion, a stepped portion recessed or protrudingly provided with respect to the general portion, and an inclination portion provided between the stepped portion and the general portion, an inclination angle of the inclination portion with respect to a normal line of the general portion being equal to or more than 25° and being equal to or less than 40° and a width of the inclination portion being large beyond 0.38 mm and being equal to or less than 1 mm; disposing a first layer on at least the stepped portion and the inclination portion of the rear surface of the transparent resin layer; allowing a part covering the stepped portion in the first layer to remain and separating an excess part, other than the covering the stepped portion, in the first layer by laser irradiation; and disposing a second layer on a part not covered with at least the first layer of the rear surface of the transparent resin layer.
  • a decorative member including: a transparent resin layer provided on a rear surface thereof with a general portion, a stepped portion recessed or protrudingly provided with respect to the general portion, and an inclination portion provided between the stepped portion and the general portion; and a decorative layer provided on the rear surface of the transparent resin layer, wherein: an inclination angle of the inclination portion with respect to a normal line of the general portion is equal to or more than 25° and is equal to or less than 40°; a width of the inclination portion is large beyond 0.38 mm and is equal to or less than 1 mm; and the decorative layer includes: a first layer that covers the stepped portion of the rear surface of the transparent resin layer; and a second layer that covers a part of the rear surface of the transparent resin layer, which is not covered by at least the first layer.
  • the first layer is disposed on at least the concave or convex stepped portion and the inclination portion on the rear surface of the transparent resin layer, and the part covering the stepped portion in the first layer is allowed to remain, and the excess part in the first layer, other than the part covering the stepped portion, is separated by the laser irradiation. Therefore, it is possible to accurately separate the excess part.
  • the first layer is viewed from the surface of the transparent resin layer, it is possible to view an accurate design.
  • the inclination angle of the inclination portion with respect to the normal line of the general portion is 25° to 40° and the width of the inclination portion is large beyond 0.38 mm and is equal to or less than 1 mm.
  • the width of the inclination portion is larger than separation tolerance when the first layer is separated by the laser irradiation. Therefore, even though a molding dimensional error or a positional shift at the time of installation of a laser irradiation jig occurs in the transparent resin layer, these errors are absorbed, so that the boundary line between the first layer and the separation part, from which the excess part has been separated, can be positioned on the inclination portion.
  • the boundary line between the first layer and the separation part is allowed to be positioned on the inclination portion, so that the boundary line is prevented from being shifted on the general portion or the stepped portion.
  • the inclination angle of the inclination portion is 25° to 40°, when the first layer is viewed from the surface side of the transparent resin layer, the first layer remaining on the inclination portion is difficult to be viewed.
  • the first layer is viewed as if it covers only the stepped portion, so that it is possible to three-dimensionally view the first layer with a good appearance.
  • the separation of the excess part of the first layer is performed by the laser irradiation. Since the laser has a high degree of accuracy of an irradiation position, it is possible to accurately separate the excess part of the first layer. Therefore, according to the invention, as compared with the case in which the first layer has been formed on the stepped portion by printing such as screen printing, it is possible to accurately form a design of the first layer.
  • the printing may not be performed depending on the rear surface shape of the transparent resin layer. That is, in the screen printing, since ink is pushed out from a screen mesh and is printed, the screen mesh need to be parallel to the rear surface of the transparent resin layer.
  • the protruding part which largely protrudes on the rear surface, since the protruding part causes flow mark or weld to the transparent resin layer at the time of molding, no design is established.
  • the general portion and the stepped portion of the rear surface of the transparent resin layer may be a concave portion or a convex portion.
  • the first layer is formed on the stepped portion.
  • the decorative member of the invention is manufactured by the aforementioned decorative member manufacturing method, so that it is possible to view a design accurately formed on the uneven surface of the transparent resin layer.
