<p><P>PROBLEM TO BE SOLVED: To provide a method for producing a double-sided adhesive sheet excellent in removability using an aqueous adhesive composition, and a double-sided adhesive sheet obtained by the method. <P>SOLUTION: The method for producing the double-sided adhesive sheet 200 having adhesive layers 1 and 2 on both sides 4A and 4B respectively of a nonwoven fabric substrate 4 is provided. The method includes a step of preparing an emulsion-type adhesive composition that satisfies both of the following conditions: a viscosity at 30°C of 0.1-3 Pa s; and a solid content of 50-70 mass%. Also there is included a step of forming an adhesive layer (for example, a second adhesive layer 2) by directly coating at least one side (for example, the second side 4B) of the nonwoven fabric 4 with the adhesive composition. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
