PURPOSE:The titled adhesive, obtained by blending either one of liquid polyisoprene and polyisobutylene as a plasticizer with a base polymer, etc., having little temperature dependence and improved mechanical adaptability without permeating into base materials, e.g. polyolefin, etc., and useful for labels, etc. CONSTITUTION:An adhesive obtained by blending (A) 20-45wt% base polymer with (B) 30-55wt% tackifier resin and (C) 15-50wt% at least one of liquid polyisoprene and polyisobutylene at <=3/1 blending ratio [(A)/(C)] of the components (A)-(C). The viscosity of the above-mentioned adhesive is preferably within the range of 100-30,000cP at 180 deg.C.
