发明名称 Sheet for protecting paint films of automobiles
摘要 A sheet for protecting paint films of automobiles for adhering to the incompletely cured paint films of automobiles comprising two pack urethane paint, the sheet comprising a support and a pressure-sensitive adhesive layer formed thereon, wherein the sheet has a Young's modulus E of at least 75 N/mm<2> and a coefficient of flexural stress k represented by the formula k = Eh<3> wherein h is a thickness of the support, of 0.035 or less. The protective sheet can uniformly protect the paint films and easily be peeled and removed therefrom without causing environmental problems and adhesive remaining of the pressure-sensitive adhesive layer. Even when the sheet is adhered to incompletely cured paint films of automobiles and they are allowed to stand for a long period of time under an outside high temperature in summer, the sheet does not cause the deformation of the paint film and the microdeformations by the deformation of the paint film at the edge portion of the pressure-sensitive adhesive layer. The protective sheet can be reserved in a roll state without causing the change of form by, for example, a telescope phenomenon.
