1. An adhesive composition, comprising:
0.1 to 1 part by weight of nano particles;
50 to 95 parts by weight of acrylate resin; and
5 to 50 parts by weight of a monomer or oligomer, of acrylate or acrylic acid, containing multi-functional groups,
wherein the acrylate resin and the monomer or oligomer, of acrylate or acrylic acid, containing multi-functional groups, have a total weight of 100 parts by weight,
wherein the acrylate resin has a weight average molecular weight of 100,000 to 1,500,000,
wherein each of the nano particles has a core, a shell, and acrylate groups, where the core is silicon oxide, the shell is gold, silver, copper, or a combination thereof, and where the shell covers parts of the surface of the core, and the acrylate groups are grafted to the surface of the core,
wherein the adhesive composition has an adhesive strength of 0.5 Kg/in to 1.5 Kg/in, when attached to a 10 cm by 10 cm stainless steel plate, as measured according to the standard JIS Z 0237 test method, without any further treatment and before exposure to a near IR radiation;
and an adhesive strength of 0 to 0.3 Kg/in after exposure to the near IR radiation, where the near IR radiation has a wavelength of 800 nm to 2,500 nm, a power of 2 kW, and an intensity of 1,500 mJ/cm2 to 2,500 mJ/cm2.
