Claim 0:
1. A structural adhesive bond formed with a pressure-sensitive adhesive, the pressure-sensitive adhesive comprising:
at least one kind of an at least partly hydrogenated tackifier resin primarily compatible with at least one styrene block copolymer;
a first constituent forming a first phase having a differential scanning calorimetry softening temperature of less than 23° C., the first phase comprising:
vinylaromatic block copolymers, and
at least one of the at least one styrene block copolymer, the at least one of the at least one styrene block copolymer comprising an elastomer block comprised of unsaturated, partly, or fully hydrogenated polydiene; and
a second constituent forming a second phase that is formed from a crosslinking buildup reaction, the second phase having a differential scanning calorimetry softening temperature greater than 23° C. and a morphology of a connected nanoparticle network, the second phase comprising epoxide reactive components,

wherein
the crosslinking buildup reaction forms an interpenetrating network comprising the first phase and the second phase,
a mass ratio of the first phase to the second phase is between 85:15 and 50:50, and
the pressure-sensitive adhesive is transparent in the visible light range of the spectrum.
