Claim:
1. A process comprising: applying with an extrusion method a coating material to paper to form a coated paper, said coating material comprising an aliphatic-aromatic polyester comprising: i) from 40 to 70 mol %, based on the total of components i to ii, of a sebacic acid derivative or sebacic acid; ii) from 60 to 30 mol %, based on the total of components i to ii, of a terephthalic acid derivative; iii) from 98 to 102 mol %, based on the total of components i ii, of a C iv) from 0.01 to 2% by weight, based on the total weight of components i to iii, of a chain extender and/or crosslinking agent selected from the group consisting of: a di-functional isocyanate, polyfunctional isocyanate, isocyanurate, oxazoline, epoxide, carboxylic anhydride, an at least trifunctional alcohol, and an at least trifunctional carboxylic acid; v) from 0 to 50% by weight, based on the total weight of the components i to iv, of an organic filler selected from the group consisting of: native starch, plasticized starch, natural fiber, wood meal, and an inorganic filler, wherein said inorganic filler is selected from the group consisting of: chalk, precipitated calcium carbonate, graphite, gypsum, conductive carbon black, iron oxide, calcium chloride, dolomite, kaolin, silicon dioxide, sodium carbonate, titanium dioxide, silicate, wollastonite, mica, montmorillonite, talc, glass fibers and mineral fibers and vi) from 0 to 2% by weight, based on the total weight of the components i to iv, of at least one stabilizer, nucleating agent, lubricant and release agent, surfactant, wax, antistatic agent, antifogging agent, dye, pigment, UV absorber, UV stabilizer or other plastics additive;
