A tracking resistant pressure-sensitive adhesive tape comprising an electrically insulating film having a comparative tracking index by an tracking resistant test of the IEC method of at least 400 V, a modulus of elasticity of from 20 to 1,200 kg/mm.sup.2, and a thickness of from 5 to 150 .mu.m, and having formed on one side thereof a pressure-sensitive adhesive layer.

Tracking resistant pressure-sensitive adhesive tape

A method for coating a metal surface by forming a corrosion-protective layer on the metal surface or a defective area of a corrosion-protective layer formed on the metal surface, which comprises using a coating material selected from the group consisting of a tape-like, sheet-like and chip-like polymerizable coating material comprising a vinyl monomer and/or a vinyl group-containing oligomer and a liquid material comprising a vinyl monomer and/or a vinyl group-containing oligomer, wherein either the coating material or the liquid material contains a polymerization initiator and the material not containing the polymerization initiator contains a polymerization accelerator, and polymerizing the vinyl monomer and/or the vinyl monomer-containing oligomer in the state such that the metal surface or the defective area is covered with the coating material by interposing the liquid material therebetween, to form the corrosion-protective layer.
