Adhesive compounds and methods contain at least one reactive resin, at least one elastomer, at least one polar photoinitiator and, optionally, a non-aqueous solvent. The adhesive compounds and method further containing a non-ionic surfactant for reducing the yellowness index of the cured adhesive compound, having a reduced yellowing tendency after the crosslinking step. The adhesive compound may be preferably a pressure-sensitive adhesive compound and the elastomer may be preferably a non-polar elastomer.
