Embodiment 1

[0029]Uniformly mix 4.86 parts by weight of EL-200 (alkali-soluble resin, manufactured by Yongguang Co.); 3.42 parts by weight of R551 (polymerizable compound having ethylenically unsaturated bonds, manufactured by Nippon Kayaku Co., Ltd.); photoinitiator In the agent, 1-hydroxyl-cyclohexyl-phenyl-ketone (I-184) accounts for 0.72 parts by weight, 2,4,6-trimethylbenzoyl diphenylphosphine oxide (TPO) accounts for 2.88 parts by weight; 1.94 Parts by weight of DPMP (manufactured by Sakai chemical Industry Co., Ltd); 32.56 parts by weight of propylene glycol methyl ether acetate (PGMEA, solvent); 32.50 parts by weight of ethyl lactate (solvent); 21 parts by weight of titanium dioxide (white pigment ); 0.08 parts by weight of I1010 (manufactured by Ciba-BASF); 0.03 parts by weight of S-386 (manufactured by Asahi Whistle Co., Ltd.); and 0.01 parts by weight of HQ (manufactured by Merck, Taiwan). Prepare 100 parts by weight of a white photosensitive resin composition, and then filter ...

Embodiment 2

[0031] The preparation method of the white photosensitive resin composition of Example 2 is substantially the same as that of Example 1, the only difference is that the content of I-184 and TPO constituting the photoinitiator is different. In Example 2, I-184 accounts for 0.97 parts by weight, and TPO accounts for 2.63 parts by weight.

Embodiment 3

[0033] The preparation method of the white photosensitive resin composition of Example 3 is substantially the same as that of Example 1, the only difference is that the content of I-184 and TPO constituting the photoinitiator are different. In Example 3, I-184 accounts for 1.46 parts by weight, and TPO accounts for 2.14 parts by weight.

Abstract

Provided is a white light sensitivity resin composition comprising alkali soluble resin, polymeric composition, photoinitiator, white pigment, and solvents, wherein the photoinitiator is formed by 2,4,6-trimethylbenzoyldiphenylphosphine oxide and 1-hydroxyl-cyclohexyl-phenyl-ketone. The white light sensitivity resin composition has characteristics of not turning yellow in high-temperature baking (about 250 DEG C) and being graphical. The invention also provides the purpose of the above white light sensitivity resin composition, the composition is used in touch panels and for forming a shielding layer at the periphery of a transmittance substrate.

Description

technical field [0001] The present invention relates to a white photosensitive resin composition and its application, especially to a white photosensitive resin composition used in a touch panel and its application. Background technique [0002] Liquid crystal displays are widely used in consumer electronics products, such as smart phones, tablet computers, satellite navigation devices, and digital cameras. In recent years, in order to improve the user interface and efficiency of use, the rise of touch panels allows users to directly Input operation information on the liquid crystal display panel. Due to the advantages of portability and easy operation of electronic products equipped with touch panels, it has gradually become an indispensable basic equipment for many consumer electronics products, and has also become a major development of many consumer electronics products. direction. [0003] Thinning has become the development trend of touch panels. In order to greatly r...
