This application relates to the technical field of optical films, and discloses a micro-optical imaging film and an imaging apparatus. The micro-optical imaging film includes a body; focusing structures and pattern structures being formed on the body, the focusing structures and pattern structures being adapted to each other, so as to form an image; and e cover structures covering exterior surfaces of at least part of the focusing structures, wherein materials of the cover structures and the focusing structures are different, and a difference between a refractive index of the cover structures and a refractive index of the focusing structures is greater than or equal to 0.05. With the technical solution contained in the embodiments of this application, a capability of the imaging film to resist ambient environmental pollutions may be improved.

A resin molding is provided. The resin molding includes an optically transparent plate-shaped portion, which has a first surface having a smooth surface portion, and a second surface having plural sections, wherein each of the plural sections has a width and includes one or more convex portions which have one or more ridge lines extending in a ridge line direction. The ridge line direction of the one or more convex portions of at least one of the plural sections is different from the ridge line direction of the one or more convex portions of one or more of others of the plural sections. When the first surface of the resin molding is observed from outside, the resin molding has metallic appearance.

An embossed sheet configuring a decorative sheet includes a sheet-shaped base that has translucency, and a plurality of reflective portions provided on one surface of the base. Each of the plurality of reflective portions has a reflective main surface that reflects incident light, and connecting surfaces that are provided between the reflective main surface and the base. Each reflective main surface is rectilinear on a first cross-section and curvilinear on a second cross-section. A gradient of a straight line at a center position of the reflective main surface that is rectilinear on the first cross-section, in relation to the one surface of the base, varies within a range of ±40 degrees in each of the plurality of reflective portions. As a result, the reflective portion can reflect incident light at regular and non-regular angles.

A decoration method of a printed matter includes: forming a printed layer on a surface of a sheet or of a mounting paper with a transparent varnish, printing a predetermined pattern on the surface of the printed layer by an ink or by a resin which are capable of being adhered to the printed layer; and pressing a metal foil onto the pattern printed by the ink or the resin with an adhesive agent. The adhesive agent does not adhere to the printed layer but adheres to the pattern. As a result, the metal foil 6 is printed only to the pattern.

Provided are an electronic device housing, a preparation method therefor and an electronic device therewith. The electronic device housing comprises a housing body and a logo layer, wherein the housing body is provided with a first surface and a second surface which are opposite each other, the first surface is provided with a first area and a second area which are adjacent to each other, the second area is located on the periphery of the first area, and the surface roughness of the second area is greater than that of the first area; and the logo layer is arranged on the first surface, and an orthographic projection of the logo layer on the first surface coincides with the first area.

The present disclosure discloses an emblem structure in which an emblem is coupled to a part in an integral form, thereby minimizing the amount of protrusion and an image is implemented in a distorted form, and advancing the quality of a product. The emblem structure includes a base layer, an image layer disposed on an outer surface of the base layer or to be spaced apart from the outer surface, and a transparent layer deposited on the base layer to cover the image layer. The transparent layer is configured such that light is transmitted and refracted and that the light reflected by the base layer and the image layer is lost, thereby improving visual recognition of the image layer.

The printed article includes a medium having a specular reflective layer, a first line composed of a first color formed at the medium, a second line formed at the medium in a second color and formed parallel to the first line, and a prism layer formed onto at least the first line, wherein when the medium is divided into a first region, a second region, and a third region that are continuous in parallel, the first line is disposed in any one region of the first region, the second region, and the third region, the second line is disposed in any one region other than the region where the first line was formed, the prism layer is disposed across two contiguous regions including the region formed with the first line, and the section of the prism layer has a shape of a portion of the non-circular arc approximating the ellipse.
