Optical film with decorative effect and multilayer structure thereof

Abstract

The invention discloses an optical film with decorative effect and a multilayer structure thereof, and the optical film comprises a substrate and a structural layer, wherein the structural layer is combined with the substrate, and the structural layer comprises a plurality of optical geometries. Through the transmittance properties of the substrate and the plurality of optical geometries, the reflected light presents light streaks with a special visual effect because of the interference phenomenon, so that a product provided with the reflective optical film is provided except for the design effect of presenting appearance texture, and the product can present high intensity directional astigmatism reflection effect in the light, thereby improving the visibility of the optical film in a poor-light environment, and effectively improving the defect that the existing decorative materials can only increase the appearance and texture of the product, but fail to further provide the user of theproduct other practical effects.

Description

technical field [0001] The invention relates to an optical film, in particular to an optical film with a decorative effect. Background technique [0002] It is becoming more and more common for existing decorative materials to be placed on the surface of commodities such as 3C products, electrical products, suitcases and safety helmets. For example, existing decorative materials can be combined with a suitcase or a safety helmet The outer surface of the product can produce a unique visual effect through the visual characteristics of the existing decorative materials, and can present different patterns or colors on the surface of the product, increasing the texture and appearance of the product. [0003] However, the existing decorative materials can only increase the beauty and texture of the product, have a single function, and fail to provide other practical functions for the user of the product. For example, when walking in a dimly lit space, the user wears a modern Hard...

Problems solved by technology

[0004] In order to solve the shortcomings of the existing decorative materials that can only increase the beauty and texture of the product, have a single function, and fail to provide other practical functions for the user of the product, the present invention provides a reflective optical film, which has an optical reflection effect of astigmatism. The structure can provide the variability of the appearance texture of the reflective optical film. In addition to presenting the design effect of the appearance texture, it also provides products equipped with the reflective optical film. It can present high-intensity directional astigmatism reflection effect under the condition of light, and improve the The visibility of the reflective optical film in an environment with insufficient light, and provide users with an extra layer of security in a dark environment. The detailed structure of the reflective optical film is further explained as follows
