<p>PROBLEM TO BE SOLVED: To provide a method of producing an adhesive tape which allows production of an adhesive tape having excellent adhesion to a substrate (core) having a fine irregular surface, for example, a foam substrate, and excellent shear adhesive strength and adhesion retention in high-temperature environment even when an aqueous adhesive, instead of a solvent type adhesive, is used.SOLUTION: A method of producing an adhesive tape includes a step [1] of mixing an adhesive composition (a1) with a cross-linking agent (a2), a step [2] of keeping the mixture obtained by the step [1] at 0-80°C to obtain an aqueous adhesive (A) and a step [3] of forming an adhesive layer on both sides of a substrate (B) by using the aqueous adhesive (A), and the keeping period in the step [2] is within a week.</p> |
