The invention relates to a support-free pressure-sensitively adhesive shaped article having a glass transition temperature of less than 10° C. which comprises a binder and a nonionic surfactant or a mixture of two or more nonionic surfactants, the binder present comprising an addition polymer or addition copolymer. The invention further relates to a process for producing such support-free, pressure-sensitively adhesive shaped articles and to the use of nonionic surfactants for adjusting the bond strength of a pressure-sensitively adhesive shaped articles. A self-supporting and self-adhesive molded article is described having a glass transition temperature of less than 10° C. and containing a binder and an aliphatic or cyoaliphatic nonionic surfactant. The binder may contain at least one addition polymer or addition copolymer. The article is redetachable from the material surfaces to which it may be adhered. Thus, the article may be attached, detached and reattached to a wall or cabinet surface and may have paper or other light weight, decorative material attached, detached and reattached to it. The detachment and reattachment process maybe repeated numerous times, particularly with intervening cleaning of the surface of the self-supporting and self-adhesive molded article.
