The binding agent comprises a (meth)acrylate copolymer, an olefinically unsaturated monomer and a radical initiator. A binding agent (I) for road marking paint comprises: (A) 20-80 % a (meth)acrylate copolymer; (B) 20-80 % an olefinically unsaturated monomer; (C) a radical initiator. (A) is prepared from: (A1) 10-50 % of a 4-18C mono-epoxide, a lactone or lactam; (A2) 1-25 % of an olefinically unsaturated monomer containing a carboxylic, sulfonic or phosphonic acid group; (A3) 5-70 % of a methacrylic acid ester of a 1-20C alcohol; (A4) 2-84% of an acrylic acid ester of a 2-20C alcohol; and optionally (A5) up to 70% vinyl monomers. It is prepared by addition of monomers (A2)-(A5), and a radical initiator, to the compound (A1). Independent claims are also included for: (i) a process for the preparation of (I) by dissolving (A) in (B); (ii) a road marking paint containing (I), a filler mixture and a radical initiator (C). |
