Abstract:
The present invention is an oil-resistant adhesive composition including a hydroxy alkyl (meth)acrylate having an alkyl group containing 2 to 4 carbons, a short alkyl (meth)acrylate having an alkyl group containing 6 or less carbons, and a photo-initiator. After the adhesive composition is soaked in oleic acid at room temperature for 7 days, the adhesive composition has an expansion percent of less than about 10%.
