Problems solved by technology

The surface dyne value of existing hardened film products on the market is mostly around 32Dyne to 36Dyne, and its dyne value will show different degrees of attenuation with time and different storage conditions, resulting in poor printing and coating effects and easy coating. Falling off, it is difficult to meet the requirements of downstream customers for a long time

Abstract

The invention discloses a hard coating film with a high dyne value, comprising a PET supporter, and a hard coating layer formed by solidifying after coating hard coating layer coating on at least one surface of the PET supporter, wherein the hard coating layer coating has the following components in parts by weight: 15-50 parts of matrix resin, 2-10 parts of oxide particles, 0.05-5.0 parts of surface additive, 0.05-7.0 parts of photoinitiator and 40-80 parts of solvent. The dyne value of the hard coating film provided by the invention can reach 38Dyne-46Dyne, thus being capable of meeting operating requirements of customers on subsequent ITO coating technology and ink printing technology.

Description

technical field [0001] The present invention relates to coating compositions, especially a hardened film having a high factor value. Background technique [0002] Hardened film is a film product obtained by surface hardening treatment on a PET support. The product has good optical properties, excellent scratch resistance, heat resistance and appearance quality. Mainly used in the touch screen industry, widely used in touch panels, liquid crystal displays, instrument panels, mobile phones, tablet computers, digital cameras, notebook computers and industrial displays, etc. At present, there are many kinds of hardened film products on the market, and the common hardness ranges from 1H to 4H, which are mass-produced. In the subsequent processing, in addition to the basic performance requirements, the surface hardened layer is also required to have good adhesion to the ink to ensure excellent printing. As a result, in the hardened film products for ITO coating, in order to achi...
