Self-adhesive protective film for painted surfaces comprising a single- or multi-layered, in particular polyolefinic support layer and a self-adhesive layer, characterized in that the self-adhesive layer is made up as follows: one or several elastomers based on block copolymers, comprising polymer blocks formed from vinyl aromatics (A blocks), preferably styrol and those formed by polymerisation of 1,3-dienes (B blocks), preferably butadiene and isoprene, or the hydrogenation products thereof, 30 to 180 parts of adhesive resin, based on 100 parts of the elastomer and 20 to 170 parts of polymeric softeners, coming from the group of polyethylene/propylene copolymers, polyisobutylene and polybutylene, with a softening temperature below 25° C. and the sum of the component parts of resin and polymeric softener does not exceed 200 parts.
