A pressure-sensitive adhesive product contains a substrate having formed
on at least one surface thereof a pressure-sensitive adhesive layer,
wherein the substrate is formed from a styrene-based resin composition
and the pressure-sensitive adhesive layer is formed from an acrylic
pressure-sensitive adhesive containing an acrylic polymer, a liquid
paraffin, and a rosin-based tackifying resin. In the acrylic
pressure-sensitive adhesive, the ratio of the liquid paraffin is
preferably 6 to 50 parts by weight based on 100 parts by weight of the
acrylic polymer and the ratio of the rosin-based tackifying resin is
preferably 1 to 30 parts by weight based on 100 parts by weight of the
acrylic polymer. The liquid paraffin may have a number-average molecular
weight of 300 to 500 and may have a dynamic viscosity at 37.8.degree. C.
of 6 to 80 mm.sup.2/second.
