Removable adhesive sheet

A removable adhesive sheet comprising a laminate of a release liner, an adhesive layer and a surface stock, wherein the adhesive layer is formed between the release liner and surface stock by applying an adhesive to the release liner or to the surface stock, followed by drying,

• said adhesive comprising (i) an aqueous emulsion of a copolymer obtained by emulsion polymerization and (ii) a polyglycidyl compound having two or more epoxy groups within the molecule thereof,
• said copolymer comprising, on the whole copolymer weight basis,
• (a) 80-99% by weight of a (meth)acrylic acid C.sub.8 -C.sub.12 alkyl ester,
• (b) 0.3-10% by weight of (meth)acrylonitrile,
• (c) 0.1-5% by weight of an .alpha.,.beta.-unsaturated carboxylic acid and
• (d) 0-5% by weight of another monomer copolymerizable with the above-mentioned monomers (a), (b) and (c),
• said copolymer having a polystyrene-equivalent number average molecular weight of not less than 0.1.times.10.sup.4 but less than 5.0.times.10.sup.4, a polystyrene-equivalent weight average molecular weight (Mw)/ polystyrene-equivalent number average molecular weight (Mn) ratio (Mw/Mn) of 40-800, an average particle size of 100-500 nm and a glass transition temperature of not higher than -50.degree. C., and
• said polyglycidyl compound being used in an amount such that the epoxy groups amount to 0.5 to 2 equivalents relative to the carboxyl groups in said copolymer.
