Abstract
Abstract An adhesive composition containing unsaturated polyesters or acrylates dissolved in organic solvents which include unsaturated carbon-to-carbon bonds; polymerizing agents, i.e., polymerization initiators or catalysts; a product of interaction of allyl alcohol with a diisocyanate derivative and benzoyl chloride; and a fluorinated alcohol of the general formula C n F 2n +1 OH, wherein n = 5 to 15.
