Embodiment 1

[0043] First, a PET base material layer is provided, and the shrinkage rate of the PET base material layer in the machine direction is 0.5%, and the shrinkage rate perpendicular to the stretching direction is 0.05%.

[0044] Carry out the preparation of the second hard coat layer then, join hardening solution (Arakawa, Japan: FZ001) in the methyl isobutyl ketone solvent and stir for 1 hour, control the solid content (active ingredient content) of hardening solution to be 30%, by coating process, forming a second hard coat layer with a thickness of 2.0 μm on one surface of the PET substrate layer.

[0045] Next, a first hard coat layer was provided on the surface of the PET substrate layer away from the second hard coat layer.

[0046] Mix silicon dioxide particles with a particle size of 50nm and a hardening solution (Arakawa, Japan: FZ001), and add the mixed solution into a methyl isobutyl ketone solvent and stir for 1 hour, and control the solid content of the mixed solution...

Embodiment 2

[0049] The same process as in Example 1 was used to form the double-sided cured film of Example 2. The specific structural parameters of the double-sided cured film are shown in Table 1, and the three-dimensional pattern effect and haze are shown in Table 2.

Embodiment 3

[0051] The double-sided cured film was formed by the same process as in Example 1. The specific structural parameters of the double-sided cured film are shown in Table 1, and the three-dimensional pattern effect and haze are shown in Table 2.

Abstract

The invention provides a double-face hardened film and a capacitance touch screen with the double-face hardened film. The double-face hardened film comprises a first hard coating, a PET base material layer and a second hard coating. The PET base material layer is arranged on the surface of the first hard coating, the second hard coating is arranged on the surface, away from the first hard coating, of the PET base material layer, and the thickness of the second hard coating ranges from 1.5 micrometers to 2.5 micrometers. The thickness of the second hard coating of the double-face hardened film is small, deformation of the second hard coating at high temperature can be effectively reduced, the deformation degree of etched and baked ITO conducting layer patterns is reduced, the chromatic aberration of an etched pit and an ITO conducting layer is prevented from being obvious, stereoscopic patterns of the capacitance touch screen are effectively improved, and the requirements of clients are met.

Description

technical field [0001] The invention relates to the field of touch screens, in particular to a double-sided cured film and a capacitive touch screen comprising the double-sided cured film. Background technique [0002] The capacitive touch screen is a four-layer composite glass screen, which generally includes from top to bottom: a substrate, a sensing layer, an OCA adhesive layer and a display screen. layer. [0003] At present, the above-mentioned substrates are double-sided hardened films, such as figure 1 As shown, the film includes: a first hard coat layer 10', a PET substrate layer 20', a second hard coat layer 30' and a protective film 40', and the PET substrate layer 20' is arranged on the second hard coat layer 30' On the surface of the first hard coat layer 10' is arranged on the surface of the PET substrate layer 20' far away from the second hard coat layer 30', and the protective film 40' is arranged on the surface of the second hard coat layer 30' away from th...
