1. A resin mixture comprising:
at least one compound that can be radically polymerized, at least one polymerization inhibitor, which is selected from stable N-oxyl-radicals or 4-hydroxy-3,5-di-tert-butyl toluene, and at least one reactive diluent, which is selected from 1,3-dicarbonyl compounds with the general formula (I) in which R1 represents a straight-chained or branched, optionally substituted C1-C6-alkyl group, preferably C1-C2-alkyl group; R3 represents hydrogen or a straight-chained or branched, optionally substituted C1-C6-alkyl group, a C1-C6-alkoxy group, or a methacryloyloxy group with the formula (II) in which X represents a methylene glycol, ethylene glycol, or propylene glycol group, and n an integer with a value from 1 up to including 6, R2 represents hydrogen, a straight-chained or branched, optionally substituted C1-C6-alkyl group or a C1-C6-alkoxy group, or together with R3 forms an optionally substituted five or six-membered aliphatic ring, which optionally comprises heteroatoms in or at the ring; or 1,3-dicarbonyl compounds with the general formula (Ill) in which R4 represents a bivalent or polyvalent alcohol, x represents an integer between 1 and 6, and R1 and R2 are the same as defined aboveWherein the ratio of at least one 1,3-dicarbonyl compound and the polymerization inhibitor ranges from 30:1 to 150:1. |
