Problems solved by technology

However, although the film formed by the coating composition has good characteristics such as impact resistance and low turbidity, it is easy to cause the film to peel off due to the poor match between the adhesiveness and the substrate used in the optical process. , and the corrosion resistance to organic solvents

Abstract

The laminated material with optical coating is prepared through providing one substrate, forming one pre-coating on the substrate and forming one film of light hardened composite on the pre-coating by means of light irradiation. The light hardened composite forms the coating with low birefraction rate, high transparency, low turbidity and other optical characteristics, as well as excellent adhesion, high chemical solvent resistance, high weather resistance, etc. and is suitable for making various optical assemblies.

Description

Technical field [0001] The present invention relates to an optical film layer and its manufacturing method, in particular to an optical coating laminate and its manufacturing method, in particular to an optical film with low birefringence, high transmittance and high solvent resistance Optical coating laminate and its manufacturing process. Background technique [0002] In recent years, with the rapid development of flat-panel display technology, the improvement of displays has also focused on the requirements of small size and light weight, such as liquid crystal display (LCD) and organic light emitting diode (organic light emitting diode). OLED) has attracted the most attention, especially for its advantages of low voltage drive, low power consumption, easy portability, little space, good quality and quality, and mass production. It has been widely used in mobile phones, PDAs, calculators, desks, etc. Large-scale or portable computers, digital cameras, car navigation systems an...
