SOLUTION: The curable composition comprises (a) a (meth)acrylate comprising (a-1) an alkyl (meth)acrylate and (a-2) a hydroxyalkyl (meth)acrylate, (b) an organic peroxide, and (c) a thiourea derivative. The curable composition may further contain (d) an acidic phosphoric acid compound. In the curable composition, (c) the thiourea derivative comprises ethylene thiourea and/or acetylthiourea. An adhesive composition comprises the curable composition. A speaker is manufactured by gluing a three-part point comprising a cone, a voice coil, and a damper using the adhesive composition. A motor and a housing are manufactured by using the adhesive composition. COPYRIGHT: (C)2011,JPO&INPIT |
