Problems solved by technology

Filling particles are generally added to the coating to achieve the desired effect (such as optical effect, matte effect, slippery, anti-adhesive effect), and once the filling particles aggregate, defects will occur on the coating, such as through Voids are left in the extended coating or the surface of the coating is uneven, which is not conducive to the application of polyester film
In addition, polyester films are usually harvested in rolls and then pulled out to a certain length during use; however, during the process of pulling out the polyester film, the surface of the film is prone to sticking and damage
In addition, the polyester film also needs good adhesion in use, so as to avoid incomplete fit with the target and fail to exert the expected effect

Abstract

An aqueous surface coating solution composition and a polyester film structure are disclosed. The aqueous surface coating solution composition includes 5-20 wt % of a resin composition and 0.15-5 wt % of an inorganic particle dispersion liquid. The resin composition includes 0.01-10 wt % of a polyester resin, 2-19 wt % of an acrylate-grafted polyurethane resin, and 0.5-10 wt % of a cross-linking agent. The inorganic particle dispersion liquid includes a plurality of first inorganic filling particles and a plurality of second inorganic filling particles, and the first inorganic filling particles have a larger average particle diameter than the second inorganic filling particles. Therefore, the surface coating liquid composition can form a surface coating with specific surface roughness on a polyester film, so the applicability of the polyester film is improved.

Description

technical field [0001] The invention relates to a surface coating liquid composition, in particular to a surface coating liquid composition for improving the applicability of a polyester film, and a polyester film structure using the surface coating liquid composition. Background technique [0002] Optical films, such as reflective films, diffusion films, and brightness enhancement films, are widely used. For example, optical films can be configured in the backlight module of a liquid crystal display to enhance the display effect. Biaxially stretched polyester film can be used to make optical films because of its high transparency, excellent chemical resistance and dimensional stability, but the properties of polyester film itself are not enough to meet the application requirements of various optical films . [0003] In addition to being related to the crystallinity of the substrate (such as PET substrate) and the type and content of additives in the substrate, the properti...
