PROBLEM TO BE SOLVED: To obtain a pressure sensitive adhesive composition, and to provide a method for producing the same, capable of simply grasping an amount of a curing agent to be added and its distribution, and thereby giving the pressure sensitive adhesive having high uniformity. SOLUTION: This two-part liquid system pressure sensitive adhesive composition comprises a solution containing a main component polymer as an essential component, and another solution containing a curing agent and a tackifier resin as essential components, wherein the tackifier resin has an observable absorbance and does not have reactivity with the curing agent. Pressure sensitive adhesive tapes are prepared using the pressure sensitive adhesive composition. The method for producing the pressure sensitive adhesive composition comprises selecting a compound, which has the observable absorbance and dose not have the reactivity with the curing agent, as the tackifier, then mixing the tackifier with the curing agent, and finally adding the mixture to the main component polymer.
