PURPOSE: To simply obtain an acrylic adhesive double-coated tape having different stickiness properties on each side. CONSTITUTION: This tape is obtained by coating a releasing sheet with a composition consisting of (A) 100 pts.wt. of photopolymerizable monomer mixture of alkyl (meth)acrylates and vinyl monomers having a polar group, (B) 0.01-1 pts.wt. of monomer having at least two reactive double bonds, (C) 0.01-5 pts.wt. of photopolymerization initiator and (D) 0.05-1 pts.wt. of titanium oxide of 0.001-1μm average particle size, and photopolymering with ultraviolet rays on the coated side.
