Patent ID: 8197896

Claim:
A method for producing a pressure-sensitive adhesive tape or sheet comprising: preparing a precursor of a pressure-sensitive adhesive agent which is an uniform mixture of 100 parts by weight of a polymer selected from the group consisting of the polymer represented by the formula (2) and the polymer represented by the formula (3), wherein Z is a polyoxyalkylene ether residue, R, R 2 , or R 3 is an alkyl group with 1 to 20 carbon atoms, X is a hydroxyl group or an alkoxy group, n =0, 1, or 2, and m is at least 2 wherein Z is a polyoxyalkylene ether residue, R, R 2 , or R 3 is an alkyl croup with 1 to 20 carbon atoms, X is a hydroxyl group or an alkoxy group, n =0, 1, or 2, and m is at least 2, 10 to 150 parts by weight of tackifying resin and 0.001 to 10 parts by weight of a fluorine-containing compound selected from the group consisting of boron trifluoride, complex of boron trifluoride, fluorinating agent and alkali metal salt of fluorine-containing inorganic acid; coating on the surface of a tape substrate or a sheet substrate with the precursor; and after that, forming the precursor into a pressure sensitive adhesive layer by curing the polymers.
