## Abstract

Provided is an adhesive tape which sequentially comprises a first adhesive layer, a polyurethane foamed layer having a density of about 0.1 g/cm3 to about 0.5 g/cm3, and a second adhesive layer.

## Claims

### Claim 1

An adhesive tape for use in bonding of a TV bezel, sequentially comprising:
a first adhesive layer;
an inner polyurethane foamed layer, having a density of 0.1 g/cm3 to 0.5 g/cm3; and
a second adhesive layer,
wherein the polyurethane foamed layer has pores with an average diameter of 50 microns to 200 microns,
wherein the polyurethane foamed layer has a thickness of 0.2 mm to less than 5.0 mm; and
wherein the adhesive tape has a width of 1 mm to 7 mm,
wherein the polyurethane foamed layer has a compressive strength of 100 gf/in2 to 2000 gf/in2,
wherein the polyurethane foamed layer has a tensile strength of 2 kgf/in2 to 20 kgf/in2, and
wherein the adhesive layers comprise at least one of acrylic adhesives, rubber adhesives, silicone adhesives, or combinations thereof.

### Claim 2 (depends on 1)

The adhesive tape for use in bonding of a TV bezel according to claim 1, wherein the adhesive tape has a shear strength of 0.3 kg/cm2 to 1.0 kg/cm2 at 80° C.
