Preferably, the PS pol5mier is a HIPS t)q)e. As curatives of photocatalysts, e.g., A/-methyl-4-picolinium hexafluorophosphate or thermal curing agents are used. Photocatalysts include two general t)q)es onium salts and cationic organometallic salts. Both are useful in the curing of the adhesive composition.
