Problems solved by technology

[0006] The car light shown in the figure is effective in that bright colored light can sometimes be seen with the pattern of the vapor-deposited film due to movement of the line of sight, and sometimes it cannot be seen; 3D effect
Moreover, since the structure of the printed sheet is complicated, its manufacturing process becomes cumbersome, and this inevitably leads to an increase in manufacturing cost
For example, the process of forming a vapor-deposited film on a resin sheet to form a pattern requires a masking material having the same pattern as the printed film, and coating a relief printing layer with the same pattern on

Embodiment 1-15 and comparative example 1-3

[0107] A laminated film having the following layer configuration was produced.

[0108] Adhesive layer (clear acrylic adhesive, 35 microns thick) / metal coating (evaporated tin layer, 0.5 microns thick) / base layer (polyurethane film, 50 microns thick) / black coloring layer (polyurethane film, 5 microns thick) / Transparent layer (transparent polyurethane film, 20 microns thick)

[0109] As shown in the table, the laminated film was cut into pieces of different widths, and these pieces were arranged to have different pitches (circular values ​​in which transparent parts and light-shielding parts were repeated alternately) p, in this case Next, the sheets are integrated by a carrier tape with an adhesive. The obtained strip-shaped decorative film was pasted to a colorless and transparent acrylic sheet (2 mm thick), and pressed.

Abstract

A decorative structure that has a remarkably excellent three-dimensional effect, thus having an excellent design, and can be easily manufactured. The decorative structure comprises a underlayer member having a mirror-like appearance surface; and a decorative film disposed apart from the mirror-like appearance surface of the underlayer member, wherein: the decorative film is provided with at least one appearance-modifying layer and has a predetermined pattern originated from a combination of light-permeating portions and light-shielding portions; an opening percentage is 10 to 99 %; and the ratio (d/p) of a distance (d) between the decorative film and the mirror-like appearance surface to the pitch (p) of the light-permeating portions and the light-shielding portions in the decorative film is at least 1/40.

Description

field of invention [0001] The present invention relates to a decorative structure, and more particularly to a decorative structure, such as a lamp or a decorative article, which can provide an excellent three-dimensional effect and appearance, etc., to attract people's attention. The invention also relates to a decorative film for producing such a decorative structure. Background of the invention [0002] Various types of vehicles, including cars and trucks, have red brake lights and / or tail lights that illuminate simultaneously when the brakes are applied, amber turn signals that illuminate simultaneously when the turn indicator switch is applied, and simultaneous Lighted colorless reverse lights, etc. Various vehicle lamps generally include a housing having a light emitting opening in a front portion thereof, a plate-shaped or lens-shaped lampshade covering the lighting opening, and a light source disposed in a lamp cavity defined by the housing and the lampshade. The in...
