Abstract

The invention discloses a fingerprint pollution preventing transparent hardening film which comprises a transparent support body and a transparent hard coating coated on the support body, wherein the transparent hard coating comprises the following components in parts by weight: 10-55 parts of UV (Ultraviolet) acrylic resin low polymer, 5-45 parts of multi-functionality UV acrylic acid monomer, 1-15 parts of photoinitiator, 0.2-2.0 parts of modified perfluoropolyether, 0.05-0.5 part of flatting agent and 15-80 parts of solvent. The fingerprint pollution preventing transparent hardening film disclosed by the invention meets the expected scratch resistance and wear resistance of the transparent hardening film while ensuring the lasting fingerprint pollution resistance, and can be widely applied to the fields of surface protection and in-mould decoration of optical display devices.

Description

technical field [0001] The invention relates to a hardened film, in particular to a transparent hardened film for preventing fingerprint pollution, and belongs to the field of film materials. Background technique [0002] With the rapid development of consumer electronics, transparent hardened films are widely used in the display device industry and in-mold decoration (IMD) fields, such as various optical components in PCs, TVs, video games, mobile phones, aerospace and automotive industries. In-mold decorative nameplates such as display devices and membrane switches, the main purpose of the transparent hardened film is to prevent the surface of these devices from being scratched or form dust pollution marks on the device. Today, touch panels are more and more widely used in people's lives, such as Iphone touch mobile phones, Ipad touch computers, etc. In addition to the above problems, the biggest problem encountered during use is fingerprint pollution, and fingerprints are...
