Abstract

An unsaturated polyester suitable as a binder which comprises a reaction product of PA0 (A) an acid component comprising one or a mixture of .alpha.,.beta.-mono-olefinically unsaturated dicarboxylic acids or polycarboxylic acids free from polymerizable carbon-carbon multiple bonds or functional derivatives thereof, PA0 (B) a polyhydric alcohol, PA0 (C) a polycyclic compound containing a norbornane ring system and having one or more identical substituents selected from carboxyl, hydroxy and amino groups, and PA0 (D) an acrylic compound which is capable of condensing with at least one of components (A) to (C), i.e. a hydroxyalkyl ester of acrylic or methacrylic acid having up to 3 carbon atoms in the hydroxyalkyl groups, or -alkylol-acryl- or methacrylamides containing up to 4 carbon atoms in the alkylol group or mixtures thereof and a process of their preparation.
