The invention relates to a plastisol comprising the following in a mixture: I) one or more polymers and/or copolymers of (meth)acrylates obtained by polymerisation of compounds containing the following polymerisable constituents: A) 20 to 100 wt. % methylmethacrylate, B) 0 to 80 wt. % of a (meth)acrylate of formula (I) that is different from methylmethacrylate, R1 representing hydrogen or methyl and R2 representing a linear or branched alk yl radical with 1 to 18 carbon atoms, C) 0 to 40 wt. % of a vinylically unsaturated monomer that is different from A) and B), and D) 0 to 40 wt. % o f an adhesion-promoting monomer, A) to D) totalling 100 wt. % of the polymerisable constituent; II) plasticizers that are compatible with the polymers and/or copolymers from I) in quantities of 5 to 400 parts by weight for 100 parts by weight of said polymers and/or copolymers; III) inorganic fillers in quantities of 0 to 700 parts by weight for 100 parts by weight of the components from I). The inventive plastisol is characterized in that the polymers and/or copolymers of the (meth)acrylates are a) emulsion polymers with b) a bi- or multimodal size distribution of the primary particles. In addition to improvements in term of the mechanics of the resulting films, th e inventive plastisols themselves have improved resistance to storage and an excellent compatibility with economical plasticizers. The plastisols also permit a relatively high binder content.
