    摘要: Curable compositions include a urethane (meth)acrylate oligomer having a number- average molecular weight of at least 6000 g/mol; at least one mono(meth)acrylate monomer; a multifunctional crosslinking monomer chosen from acrylate monomers, methacrylate monomers, or combinations thereof; and an ethylene–vinyl acetate grafted terpolymer. The mono(meth)acrylate monomers may include a first mono(meth)acrylate with Tg between 50 °C and 175 °C and a second mono(meth)acrylate with Tg between −50 °C and 30 °C. The curable compositions may be applied onto a surface of a substrate then cured to form a low-tack adhesive layer on the surface. The curable compositions may be cured by exposure to visible radiation, UV radiation, LED radiation, laser radiation, electron-beam radiation, peroxide, accelerator, or heat. Methods for bonding substrates include contacting a second substrate to a low-tack adhesive layer on a first substrate, then heating the low-tack adhesive layer to bond the substrates and form a laminate.
