ABSTRACT:
This invention relates to a thermosetting, substrate-free, storage-resistant synthetic resin foil which is hard, scratch- and abrasion-proof in the hardened state, comprising: (a) about 60 to 95% by weight of a hardenable polyester resin, (b) about 1 to 15% by weight of a cross-linking agent for the polyester resin, (c) about 5 to 40% by weight of a thermoplastic containing predominantly linear, high-molecular weight reactive groups, (d) about 1 to 15% by weight of a monomer with at least one polymerizable double bond and at least one group reactable with the reactive group of the thermoplastic under the conditions of reaction, (e) and at least one hardening catalyst, and optionally dyestuffs, pigments and/or fillers. The invention also relates to a process for preparing the novel foil of the invention.
