<P>PROBLEM TO BE SOLVED: To provide a surface protection sheet which has good adhesion to paintwork with a rough surface and by which not only remaining adhesives are visually observed but also self-cleaning properties on a surface of a painted plate are not diminished. <P>SOLUTION: The surface protection sheet includes a base material layer and an adhesive layer. The main component included in the adhesive which composes the adhesive layer is a polymer P obtained by crosslinking a polymer A. In the pulse NMR measurement of the polymer P at 30°C, the maximum spin-spin relaxation time T2<SB POS="POST">MAX</SB>of all the spin-spin relaxation time T2 of the proton measured is in the range of 300-800 μs, and the content ratio of the polymer component corresponding to the maximum spin-spin relaxation time T2<SB POS="POST">MAX</SB>in the polymer P is 60% or more. <P>COPYRIGHT: (C)2012,JPO&INPIT |
