Self-supporting and redetachable adhesive article

A self-supporting, shaped article having a first pressure-sensitively adhesive surface, a second pressure-sensitively adhesive surface, and a glass transition temperature of from about 0 to about −60° C., wherein:

• the shaped article is in web or sheet form having thickness of about 0.01 to about 10 mm;
• the shaped article is comprised of at least 90% by weight of a binder and from 0.05 to 0.8% by weight of at least one nonionic surfactant selected from the group consisting of one or more compounds of general formula (I)
• R1[—(O—CR2H—CH2)nO—CR2H—CH2—OH]y (I)
• wherein R1 represents an alkyl radical of 2 to 26 carbon atoms or a cycloalkyl radical of 4 to 26 carbon atoms, R2 in each case independently represents hydrogen or an alkyl radical of 1 to about 10 carbon atoms, n is a number form 0 to 200, and y is a number from 1 to 6;
• one or more alkyl polyglycosides of general formula (II)
• R3O—(Z)x (II)
• wherein R3 represents an alkyl radical of 2 to 24 carbon atoms, Z independently at each occurrence represents a monosaccharide or oligosaccharide of a sugar having 5 or 6 carbon atoms and X represents a number tom 1.1 to 5;
• and
• mixtures thereof;
• said binder comprises at least one polymer selected from the group consisting of addition polymers, addition copolymers and mixtures thereof, with at least one polymer being prepared by addition polymerization or copolymerization of at least one ester selected from the group consisting of esters of acrylic acid and esters of methacrylic acid and in the form of an aqueous emulsion or dispersion having a solids content of between about 20 and about 90% by weight;
• and
• said first and second pressure-sensitively adhesive surfaces having an essentially identical bond strength with respect to identical material surfaces, and
• wherein said first and second pressure-sensitively adhesive surfaces are redetachable from the same or different material surfaces.

A method of removably adhering an article to a surface, said method comprising (1) obtaining a self-supporting, shaped article having a first pressure-sensitively adhesive surface and a second pressure-sensitively adhesive surface and a glass transition temperature of less than 10° C., comprising

• (a) at least 90% by weight of a binder comprised of at least one polymer selected from the group consisting of addition polymers, addition copolymers, and mixtures thereof;
• and
• (b) from 0.01 to 1.44% by weight of at least one nonionic surfactant selected from the group consisting of aliphatic nonionic surfactants, cycloaliphatic nonionic surfactants and mixtures thereof,
• wherein said first and second pressure-sensitively adhesive surfaces have an essentially identical bond strength with respect to identical material surfaces, and wherein said first and second pressure-sensitively adhesive surfaces are redetachable from the same or different material surfaces;
• (b) adhering the first pressure-sensitively adhesive surface of the self-supporting, shaped article to said article and adhering the second pressure-sensitively adhesive surface of the self-supporting, shaped article to said surface or in the reverse order, and,
• (c) detaching either the self-supporting, shaped article from said surface or detaching the article from the self-supporting, shaped article.
