HALOGEN-FREIES ACRYLURETHAN-FOLIENMATERIAL

摘要

A halogen-free acrylic urethane sheet material (10) is disclosed which can be marked by conventional printing methods and by radiation methods. The halogen-free acrylic urethane sheet material of the invention is manufactured from a polymer comprising components A, B and C wherein component A comprises a copolymer of (i) a monoester of acrylic or methacrylic acid and an aliphatic diol having 2 to 8 carbon atoms and (ii) an ester of acrylic or methacrylic acid and an aliphatic alcohol having 1 to 8 carbon atoms, and optionally a vinyl aromatic monomer as well as N-vinylpyrrolidone or N-vinylcaprolactame, said component A having a Tg of 30 DEG C to 100 DEG C, component B comprising an aliphatic polyester diol with a molecular weight less than 20,000 and component C comprising a polyfunctional isocyanate or blocked polyfunctional isocyanate.
