发明名称 MASKING LAYER FORMED BY APPLYING DEVELOPABLE PHOTOSENSITIVE RESIN COMPOSITIONS ON PANEL STRUCTURE
摘要 The invention relates to a masking layer. The masking layer produced by coating a white-color photosensitive resin composition on a peripheral region of a transparent substrate, developing the white-color photosensitive resin composition to obtain a patterned composition layer, coating a gray-color photosensitive resin composition on the cured composition layer and developing the gray-color photosensitive resin composition, so that the gray-color photosensitive resin composition is cured to obtain the masking layer having an optical density (O.D.) of ≧3.5. The masking layer is adapted for use on a touch panel or a flat panel display device. The masking layer shows a white color appearance when viewed from outside and serves as a white color decoration around the peripheral region of the device. The masking layer further comprises a gray colored sub-layer to mask the electrical circuitry disposed beneath the masking layer.

主权项 1. A masking layer produced by coating a white-color photosensitive resin composition on a peripheral region of a surface of a transparent substrate of a panel structure, developing the white-color photosensitive resin composition to obtain a cured and patterned composition layer, and then coating a gray-color photosensitive resin composition on the patterned composition layer and developing the gray-color photosensitive resin composition, so that the gray-color photosensitive resin composition is cured and patterned to obtain the masking layer having an optical density (O.D.) of ≧3.5, wherein: the white-color photosensitive resin composition comprises 5˜15 wt % of a resin ingredient, from more than 0 wt % to 2 wt % of a photo-initiator, 5˜15 wt % of a monomer ingredient, 40˜70 wt % of a solvent and 10˜30 wt % of a white pigment; and the gray-color photosensitive resin composition comprises 5˜15 wt % of a resin ingredient, from more than 0 wt % to 2 wt % of a photo-initiator, 5˜15 wt % of a monomer ingredient, 40˜70 wt % of a solvent, 10˜30 wt % of a white pigment and from more than 0 wt % to 3 wt % of a black pigment.
