Title:
DOUBLE-SIDED PRESSURE-SENSITIVE ADHESIVE TAPE
Document Type and Number:
WIPO Patent Application WO/2017/109883
Kind Code:
A1
Abstract:
Disclosed is a double-sided pressure-sensitive adhesive tape which comprises: a multilayer substrate that comprises a resin film 1, a black print layer 3, and at least one light-color print layer 2 disposed therebetween; and pressure-sensitive adhesive layers 4 disposed on both surfaces of the multilayer substrate. The pressure-sensitive adhesive tape is characterized in that the black print layer 3 includes a structure attributable to an aromatic isocyanate-based hardener. The multilayer substrate is less apt to suffer blocking or wrinkling, and the pressure-sensitive adhesive layer 4 on the light reflection layer side is less apt to yellow. The lightness (reflectance) of the light reflection layer is easy to regulate. This pressure-sensitive adhesive tape is useful for fixing a liquid-crystal display panel to a backlight unit.
