- X is oxygen or --NH--,
- R.sup.1 and R.sup.2 are identical or different and each is hydrogen, alkyl, alkenyl, cycloalkyl, cycloalkyl, cycloalkenyl, aryl, aralkyl or alkaryl group which has 1 to 11 carbon atoms and which is unsubstituted or substituted by one or more hydroxyl amino, epoxy, urethane, urea, ester or ether groups,
- or R.sup.1 and R.sup.2 together form a 3-membered to 6-membered ring, which is carbocyclic or contains a nitrogen, oxygen or sulphur hetero-atoms,
- R.sup.3 has the meaning of R.sup.1 or is ##STR12## or R.sup.2 and R.sup.3, together with the adjacent ##STR13## form a 5-membered or 6-membered ring, which contains only the nitrogen atom as a heterocyclic ring member or which additionally is oxygen as a further heteroatom, and
- R.sup.4 and R.sup.5 are identical or different and each is hydrogen, halogen, alkyl or alkenyl having 1 to 10 carbon atoms which is unsubstituted or substituted by halogen.
- 2. Composition according to claims 1, characterised in that the radical R.sup.1 represents hydrogen.
- 3. Composition according to claim 1 or 2, characterised in that R.sup.2 represents hydrogen or methyl.
- 4. Composition according to claim 1 or 2, characterised in that R.sup.3 represents methyl or ethyl.
- 5. Composition according to claim 1 or 2, characterised in that R.sup.4 represents hydrogen or methyl.
- 6. Composition according to claim 5, characterised in that both R.sup.4 and R.sup.5 represent hydrogen.
- 7. Composition according to claims 1 or 2 which contains the accelerator compound in an amount such that the content of tertiary nitrogen is 0.01 to 4% by weight, based on the total composition.
- 8. Composition according to claim 1 or 2, characterised in that it contains 20 to 75% by weight (based on the total resin) of .alpha.,.beta.-ethylenically unsaturated polyesters and 80 to 25% by weight of monomers which can be copolymerised with these polyesters.
- 9. Composition according to claim 8, characterised in that the copolymerisable monomer is styrene.
- 10. In an improved process of hardening an unsaturated polyester resin-containing composition by reaction with a polymerization accelerator,
- the improvement comprises said composition being reacted with a polymerization accelerating amount of compound of the formula ##STR14## wherein R is hydrogen or methyl,
- Y.sup.1 is a branched or straight chain alkyl with 1 to 6 carbon atoms,
- Y.sup.2 is a branched or straight chain alkylene with 2 to 8 carbon atoms,
- X is oxygen or --NH--,
- R.sup.1 and R.sup.2 are identical or different and each is hydrogen, alkyl, alkenyl, cycloalkyl, cycloalkyl, cycloalkenyl, aryl, aralkyl or alkaryl group which has 1 to 11 carbon atoms and which is unsubstituted or substituted by one or more hydroxyl, amono, epoxy, urethane, urea, ester or ether groups,
- or R.sup.1 and R.sup.2 together form a 3-membered to 6-membered ring, which is carbocyclic or contains a nitrogen, oxygen or sulphur hetero-atoms,
- R.sup.3 has the meaning of R.sup.1 or is ##STR15## or R.sup.2 and R.sup.3 together with the adjacent ##STR16## form a 5-membered or 6-membered ring, which contains only the nitrogen atom as a heterocyclic ring member or which additionally is oxygen as a further heteroatom, and
- R.sup.4 and R.sup.5 are identical or different and each is hydrogen, halogen, alkyl or alkenyl having 1 to 10 carbon atoms which is unsubstituted or substituted by halogen.
