A pressure sensitive reversible self-adhesive for coating one or both sides of flat substrates is new A pressure sensitive reversible self-adhesive for coating one or both sides of flat substrates contains (wt.%): (a) a copolymerizate obtained from ethylhexyl acrylate (8-95) and methyl methacrylate (on the copolymerizate); (b) a copolymerizate obtained from ethylhexyl acrylate (5-90), n-butyl acrylate (2-93), and a crosslinking agent based on N-methylol group containing amides (2-8); (c) a copolymerizate obtained from butyl acrylate (78-96.5), acrylonitrile (1-10), acrylic acid (1-4), N-methylolmethacrylic acid amide (1-4), and a crosslinking agent based on adipic acid hydrazide (0.5-4); (d) polyisobutylene (1-5); and (e) phthalic acid ester with a 4-12C alcohol component, and conventional additives. The wt.% contents of components (a) to (e) = 100 wt.% of the adhesive solids content.
