Embodiment 1

[0048] Preparation of primer coating solution (Ⅰ)

[0049]

[0050] Get 7.77g water-based UV-curable polyurethane resin UCECOAT7655 (solid content is 35%, allnex resin Co., Ltd.), 8g water-based polyester resin MD-1200 (solid content is 34%, Toyobo Co., Ltd.), 1.37g water-based epoxy Resin EX-810 (solid content is 99%, Nagase Sangyo Co., Ltd.), dispersion emulsion ST-MP of 0.5 g of silicon dioxide (solid content is 40%, Nissan Chemical Co., Ltd.), 10 g of isopropyl alcohol, 82.36 g Deionized water was uniformly dispersed by a high-shear emulsifier to obtain a primer coating solution with a solid content of 7%.

[0051] The preparation of optical polyester film is the polyethylene terephthalate polyester chip (middle layer b layer) that intrinsic viscosity is 0.65dL / g respectively; Alcohol ester polyester chips and masterbatch chips (outer layer a) containing 400 ppm of silica particles with an average particle size of 2.5 μm are melted at 280 ° C, stacked in the three-laye...

Embodiment 2

[0055] In Example 1, the undercoat coating liquid (I) was changed to other than the undercoat coating liquid (II), and an optical polyester film and a laminated polyester film for optics were obtained in the same manner as in Example 1, Measure its performance (see Table 1).

[0056] Preparation of primer coating solution (Ⅱ)

[0057]

Embodiment 3

[0059] The undercoat coating solution (I) in embodiment 1 is changed to undercoat coating solution (Ⅲ), and the single-sided coating undercoat is changed to the double-sided coating bottom layer, to be the same as in embodiment 1 The method obtains optical polyester film and optical laminated polyester film, and measures its performance (see Table 1).

[0060] Preparation of primer coating solution (Ⅲ)

Abstract

The invention discloses an optical polyester film and an optical laminated polyester film.At least one face of a biaxially oriented base film of the optical polyester film is coated with a bottom coating containing an adhesive and anti-adhesion particles, and the adhesive is prepared from, by weight, waterborne ultraviolet light cured polyurethane resin 40-90%, waterborne polyester resin 9-40% and epoxy resin 1-20%.The polyester film layer has excellent initial adhesion to an optical functional layer, also has good adhesion under the conditions of high temperature and high humidity, meanwhile has high transparency and excellent adhesion resistance and is suitable for the fields of LCD, PDP and other display devices.

Description

technical field [0001] The present invention relates to an optical polyester film with excellent initial adhesion and heat-and-moisture resistance, and to an optical laminated polyester film used in display devices such as liquid crystal televisions and plasma televisions. Background technique [0002] Biaxially oriented optical polyester film is widely used in the deep processing of various optical polyester film materials due to its good dimensional stability, chemical resistance, high transparency and good processability compared to other plastic films. It is used as base film for hard coat film, anti-reflection film, light diffusion film, lens film, transparent conductive film, etc. of liquid crystal TV (LCD), plasma TV (PDP), etc., and has market potential in the field of display devices such as LCD and PDP. huge. [0003] When the optical polyester film is used in LCD, PDP and other display devices, not only the high transparency of the film is required, but also the ...
