Coated substrates having an ultrathin, single-layer or multilayer coating, a process for their production and polyesters as intermediate products for the coated substrates A b s t r a c t Coated substrates having an ultrathin, single- layer or multilayer coating of organic polymer material have been found, in which coated substrates the polymer used is a polyester of the structure Image (I) wherein A is the skeleton of an aliphatic, araliphatic or aromatic diol, B is the skeleton of an aliphatic, araliphatic or aromatic dicarboxylic acid, n assumes values from 2 to 80 and at least one of the substituents R1 to R4 represents an aliphatic radical having an essentially normal chain and the other radicals in each case denote hydrogen or methyl, the aliphatic radical having at least 8 C atoms and it being possible for bonding of the aliphatic radical having an essentially normal chain to the skelet- on A or B also to take place via groups containing heteroatoms, and, where there are two aliphatic radicals having an essentially normal chain on one skeleton, these radicals are identical, and furthermore R1 and R2 together and R3 and R4 together may form an alkylene chain. Such coated substrates can be produced by the Langmuir-Blodgett technique. The stated polyesters are novel intermediate products for these coated substrates.
