<p>PURPOSE:To prepare a sheet for protecting a coating film, having low glass transition point of coating layer, capable of preventing the thinning phenomenon of the coating layer, having excellent coating film protecting property and suitable e.g. for the surface-protection of automotive parts, etc., by applying a specific rubber-based tacky adhesive layer to a supporting substrate. CONSTITUTION:This coating film protection sheet is produced by applying (A) a rubber-based tacky adhesive layer containing (i) 100 pts.wt. of a rubber- based tacky adhesive such as polyisobutylene, (ii) <=25 pts.wt. of a fatty acid glycerol ester such as coconut oil and (iii) 0.01-5 pts.wt. of one or more mildew- proofing agents sel.ected from the compounds of formula I (X<1> is a hadogen; R<1> is a hydrocarbon group; (m) and (n) are each 1-3), formula II (R<2> is H or a 1-4C alkyl; X<2>, Y<1> and Z<1> each is H or a halogen) and formula III (R<3> and R<4> are a 1-4C alkyl; A is sulfonyl, sulfinyl, etc.; X<3>, Y<2> and Z<2> each is H or a halogen) to (B) a supporting substrate such as a plastic film.</p> |
