Abstract: Devices and methods, in particular computer-implemented methods, for the communication of participants in a traffic infrastructure. A state channel, associated with a distributed ledger technology system, to a second participant is set up at a first participant, and a channel, associated with the state channel, to a third participant is set up at the first participant. A first instruction is sent to the third participant via the channel, such that if a second instruction of the third participant is received via the channel, and if the second instruction fulfills a condition that is a function of the first instruction, the first participant and/or the third participant are controlled as a function of the first instruction or as a function of the second instruction.

Abstract: Radiation-curable, polyester acrylate-containing compositions (I) obtainable by reacting 0.5 to 20 mol % of a polyester polyol (A) and 0.5 to 30 mol % of a polyester diol (B) with 1 to 10 mol % of phthalic anhydride (C) and 65 to 75 mol % of (meth)acrylic acid (D) in the presence of an acidic esterification catalyst, a hydrocarbon (L), and a polymerization inhibitor. Reaction temperatures range from 60 to 140° C. The hydrocarbon (L) functions as solvent, forms an azeotropic mixture with water, and is removed distillatively after esterification. Water formed in the reaction is removed azeotropically. After neutralization of the esterification catalyst, free (meth)acrylic acid is reacted with an epoxide compound (E) in an amount equivalent to the acid number of the reaction mixture. The compound (E) has at least two epoxide groups per molecule. The compositions are suitable for coating the surfaces of solid substrates.
