Summary:An object of the present invention is to provide a liquid adhesive composition that, when cured, has a high degree of bond strength and exhibits a relatively constant storage modulus in a wide range of temperatures. A liquid adhesive composition containing (A) an acrylate-functional resin, (B) a hydroxyl-containing (meth)acrylate, and (C) a silicone resin, the acrylate-functional resin (A) having a weight average molecular weight (Mw) of 25,000 to 100,000 and a Mw/Mn ratio of 2 or less, and the silicone resin (C) having a weight average molecular weight (Mw) of 450 to 2,000 and a silanol content of 0.1 to 5 wt. %, based on the silicone resin (C).
