UV-Crosslinkable pressure-sensitive adhesives containing a benzophenone-based unsaturated photoinitiator
A soln. of 2-ethylhexyl and Bu acrylates and CH2=CHCOOH in AcOEt was photo polymerized in presence of a com. thermal photoinitiator (benzophenyl methacrylate in CH2=CHMeCOOMe) and azoisobisbutyronitrile (0.1 and 0.2-1% by mass, resp.) for 3 h, dild. with i-PrOH and used for covering a polyester film. After vaporization of the solvent at 110 degrees C for 10 min, the adhesives were irradiated with UV (dose 5-50 mJ/cm(2)).
