Problems solved by technology

[0002] Although the existing protective film can play a protective role, its function is relatively single, and it does not have a unique visual effect. Therefore, it is necessary to design a protective film for continuous screen development, a preparation method and a method for continuous development of the continuous screen.

Embodiment 1

[0032] Example 1: as Figures 1~3 , an interest screen developing protective film, comprising a release film, a silica gel layer, an OCA adhesive layer and a protective film stacked in sequence; it is characterized in that a layer of developing ink is printed on the silica gel layer; the developing ink layer is located between the silica gel layer and the OCA layer. Between the adhesive layers, there is ink in some areas of the developing ink layer, and no ink exists in the rest. The area where the ink exists is the developing pattern area (used to form the developing pattern in the screen-off state).

[0033] The developed ink layer is white ink with a thickness of less than 1 u.

[0034] The developing ink layer is printed with transparent white ink below 3% (including 3%). 3% refers to 3% of white ink dots, and the white ink model is: T639B. 3% of white ink dots means that the area of ​​white ink dots accounts for 3% of the total area.

Abstract

A screen-off developing protective film, a preparing method thereof and a screen-off developing method are disclosed. The screen-off developing protective film includes a release film (1), a silica gel layer (2), an optically clear adhesive (OCA) layer (4) and a protective film (5) which are laminated in order. The screen-off developing protective film is characterized in that a developing printing ink layer (3) is printed on the silica gel layer and is between the silica gel layer and the OCA layer, some parts of the developing printing ink layer have printing ink, the rest part is free of printing ink, and zones having the printing ink are developing pattern zones. The screen-off developing protective film has unique screen-off developing effects and is easy to prepare.

Description

technical field [0001] The invention relates to a screen developing protective film, a preparation method and a screen developing method. Background technique [0002] Although the existing protective film can play a protective role, the function is relatively single, and it does not have a unique visual effect. Therefore, it is necessary to design a screen developing protective film, a preparation method and a screen developing method. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a screen developing protective film, a preparation method and a screen developing method. The screen developing protective film has a unique screen developing effect and is easy to prepare. [0004] The technical solution of the invention is as follows: [0005] A screen development protective film, comprising a release film (1), a silica gel layer (2), an OCA adhesive layer (4) and a protective film (5) stacked in sequence; characte...
