摘要： An optically transparent adhesive compound, a process for producing it and an adhesive transfer tape comprising the adhesive compound. The present invention also relates to the use of the adhesive compound. The optically transparent adhesive compound is for bonding displays, holographic optical elements, lenses and glasses, including: 80 to 100% by weight of at least one (meth)acrylate-containing copolymer A, the copolymer A composed of 15 to 95% by weight of linear alkyl (meth)acrylate monomers, wherein the number of carbon atoms of the alkyl radicals of the linear alkyl (meth)acrylate monomers is 6 to 10, and 5 to 30% by weight of hydroxy group-containing (meth)acrylate monomers. Further, the adhesive compound has a haze value of less than 5% and a transmission at 400 nm to 800 nm of more than 90%, each measured according to ASTM D1003-13.
