PROBLEM TO BE SOLVED : To provide re-releasable colored adhesive film usable as surface-protective film, carrier film or the like, good in identifiableness for its presence in use and retainable in re-releasability even if exposed to heating conditions.
SOLUTION : The re-releasable colored adhesive film is such that when a colorant layer is to be provided in between a base film and an adhesive layer, the amount of a curing agent to be added to the adhesive layer is increased at e.g. 1.1-3.0 times an appropriate amount in the case of being provided with no colorant layer.
