<p><P>PROBLEM TO BE SOLVED: To provide a sheet for protecting a coated film capable of exhibiting excellent adhesiveness even to the coated film readily causing defective adhesion by bleeding of a leveling agent etc., without carrying out a cleaning treatment etc., and sustaining a good adhesion state over a long period of time and easily peelable during peeling of the sheet after application over the long period of time. <P>SOLUTION: The sheet for protecting the coated film is a pressure-sensitive adhesive sheet comprising a pressure-sensitive adhesive layer containing a rubber-based polymer and an aliphatic (meth)acrylic oligomer having 30-100°C glass transition temperature and 1,000-20,000 weight-average molecular weight on at least one side of a support base. The sheet for protecting the coated film is characterized in that the amount of the compounded (meth)acrylic oligomer is 0.02-1 pt.wt. based on 100 pts.wt. of the rubber-based polymer. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
