摘要： PROBLEM TO BE SOLVED: To provide polyisobutylene based pressure-sensitive adhesives excellent in the balance of initial adhesion, its retention and weatherability and readily peelable again without leaving residual paste after long-term adhesion, and surface protective materials using the same. SOLUTION: Pressure-sensitive adhesives comprise, as the components, at least an isobutylene based polymer having been subjected to peptization treatment by a radical initiator in an organic solvent and 0.001-5 pts.wt., based on 100 pts.wt. isobutylene based polymer, peel controlling agent composed of an alcohol having a molecular weight of 90-300 and an oxygen atom content of not less than 8.5% or a derivative thereof or a carboxylic acid having a molecular weight of 70-400 and an oxygen atom content of not less than 11% or a derivative thereof, and surface protected materials have a pressure-sensitive layer made thereof on a support substrate. In the vicinity of the adhesion interface of the isobutylene based pressure-sensitive adhesion layer, the peel controlling agent is unevenly distributed to form a layer weak in cohesive force and thus, a pressure-sensitive adhesion layer excellent in initial adhesion, its retention and weatherability can be obtained.

摘要： PROBLEM TO BE SOLVED: To obtain a sheet which, even when it is applied to the surface of a coating film in a state containing water to protect it, does not cause the coating film to undergo denaturation or discoloration even after long-term continuos application and can allow the protective sheet to remain in an adhered state as such without peeling by forming a pressure-sensitive adhesive layer on the back of a multilayer substrate composed of a water-barrier layer being the face and a water-permeable layer being the back. SOLUTION: A water-barrier layer 11 made of a resin such as a polyolefin, a polyurethane, a polyester or an ethylene/vinyl acetate copolymer is laminated with a water-permeably layer 12 made of a porous material having a mean pore diameter of 10 μm or below, especially 0.0010-2 μm or a porous material having an apparent density of 0.85 g/cm or bellow and having a moisture permeability of 50 g/m .24 hr or above, especially 1,000-10,000 g/m .24 hr (as measured according to JIS K-0208) to obtain a multilayer substrate 1 having a thickness of 5-500 μm, especially 20-200 μm. A pressure-sensitive adhesive layer 2 made from at least one rubber pressure-sensitive adhesive selected among a polyisobutylene, a butyl rubber, and an A-B-A block copolymer is formed on the surface of the layer 12.
