  • Publication number: 20240010849
    Abstract: A decorative laminate includes a metallic layer that has excellent metallic glossiness and can reduce or prevent appearance failure, and a method of producing the same, and a metallic coating composition that can form the metallic layer. A decorative laminate includes: at least one selected from the group consisting of a substrate and a release liner; and a metallic layer containing metal pigment particles and a binder, the metal pigment parciles having a particle diameter D50 of from approximately 5 to approximately micrometers and a particle diameter D90 of from approximately 10 to approximately 30 micrometers, the metallic layer having an L* value of approximately 85 or greater.

  • Publication number: 20230323144
    Abstract: Provided is a film that has high-quality low gloss appearance with a small change in appearance of texture as observed at various viewing angles and that has tactile texture. Solution means A film of an embodiment is a film including a surface layer embossed, wherein the surface layer includes a low gloss layer and a gloss printed pattern partially covering the low gloss layer, (1) 85-degree surface glossiness of the surface layer is less than or equal to 3.5 GU as an in-plane average value; (2) ?85-degree surface glossiness defined by a difference between an in-plane maximum value of the 85-degree surface glossiness and the in-plane average value of the 85-degree surface glossiness of the surface layer (= in-plane maximum value of 85-degree surface glossiness - in-plane average value of 85-degree surface glossiness) is from 0.2 to 2.5, and (3) surface roughness Ra of an embossed surface of the film is greater than or equal to 3.5 µm.

  • Publication number: 20220177011
    Abstract: A drive control device includes a self-excited generator to generate and output electric power by being driven by an internal combustion engine, and a separately excited generator to generate and output electric power by being driven by the internal combustion engine when the separately excited generator is in an excited state. The drive control device further includes a first power converter to convert electric power fed from the separately excited generator via primary terminals into DC power and output the DC power via secondary terminals or to convert DC power fed via the secondary terminals into electric power to be fed to the separately excited generator and output the electric power via the primary terminals, and a capacitor connected between the secondary terminals of the first power converter.
