Description: BACKGROUND OF THE INVENTION The invention relates to thermosetting reactive resin mixtures and moulded articles and coatings made therefrom. Large numbers of thermosetting resin mixtures, which form cross-linked systems at raised temperature, are known. Paint binders, which contain carbamate groups - especially hydroxyalkyl carbamate derivatives - are likewise known and are relatively often used. In such cases the function of the carbamate compounds used is quite varied. Thus many binders for coatings, which contain low molecular weight hydroxyalkyl carbamates have been described. For example, such systems are the object of USP 4 520 167, EP 212 380, EP 302 222, WO 87/00851 and WO 88/02766. Similar thermosetting mixtures are described by W J Blank (J Coat. Technol. 60, (1988) No. 764, 43 and Proc. Water-Borne Higher Solids Coatings Symp. New Orleans, 1989, 332). All the stated publications concern paint binders which essentially harden by the reaction between hydroxy-functionalised polymers and amine resin or isocyanate cross-linkers; the low molecular weight hydroxyalkyl carbamates used are only used as reaction diluents and do not take part in the actual cross-linking reaction. Another group of carbamate-containing binders are the polyfunctional hydroxyalkyl carbamates, which also fall within the known state of technology. In such binders, the hydroxyalkyl urethane function is linked to a polymeric system. This chiefly relates to: a) Modified amine resins or mixtures with melamine resins (e.g. EP 152 820, EP 245 700, EP 245 701, EP 246 483, EP 257 848), b) Acrylic resins with at least two hydroxyalkyl carbamate groups (e.g. EP 152 820, USP 4 758 632), c) Polyfunctional hydroxyethyl carbamates based on amidoamines (e.g. USP 4 588 783), d) Modified epoxyresins (e.g. EP 119 769, DE-OS 3 311 517, DE-OS 3 311 518, USP 4 484 994). All the hydroxyalkyl carbamates of this group are used as activated hydroxy-functionalised polymers. At high temperature they cross-link with normal amine resin cross-linkers, e.g. with melamine resins. With suitable catalysis these resins are also capable of self-crosslinking. In hardening paint systems, similar functions are performed by hydroxyalkyl urethanes derived from low molecular weight di- or polyamines and ethylene or propylene carbonate (e.g. V V Mikheev et al., Lakokras. Mater. Ikyh Primenen. 1983, No. 6, 5; G G Parekh, Proc. Water-Borne Higher-Solids Coatings Symp. New Orleans, 1987, 492), which are also used for cross-linking with polyfunctional hydroxycompounds. It is also known that carbamates can react with epoxy groups. Y Iwakura and S Izawa describe reactions of N-aryl urethanes with arylglycidyl ethers (J Org. Chem. 29, (1964) 379; J Polym. Sci. A-14, (1966) 751). With the use of bifunctional starting compounds, linear polymers can be prepared. After a number of attempts, it had to be stated that N-alkyl carbamates do not undergo this reaction. Linear polymers from bifunctional epoxides and bifunctional carbamates were obtained by Z N Pazenko et al. (Sintez i fizikochimija polimerow 7, (1970) 42; 8, (1971) 45). In these cases also, N-aryl carbamates were used. The polymers obtained have low molecular weights, melt easily and dissolve well in most polar solvents. The same authors also state (Sintez i fizikochimija polimerow 6, (1970) 42), that under severe reaction conditions (ca. 1-2 hours at ca. 160°C) unsubstituted aliphatic carbamates can also be made to react with epoxides. In the process readily melting and easily soluble - therefore linear - polymers with low molecular weight are likewise obtained. Cross-linking systems from hydroxyethyl urethanes and epoxy resins were obtained by G Rokicki and R Lazinski (Angew. Makromol. Chem. 170 (1989) 211). Here epoxides were cross-linked with aliphatic polyamines (e.g. triethylenetetramine), which were partially modified with cyclic carbonates. The modified polyamines contain hydroxyethyl urethane groups, however also at the same time adequate amounts of reactive aliphatic H-N-functions, through which the actual cross-linking reaction proceeds - at room temperature. This case involves classical epoxide hardening by aliphatic polyamines: the hydroxyalkyl urethane groups serve only to improve the properties of the products obtained, without strictly speaking being involved in the cross-linking reaction. Attempts to prepare three-dimensional networks from polyfunctional epoxides (epoxyacrylates) and bifunctional hydroxyalkyl carbamates are described by V V Mikheev et al. (Lakokras. Mater. Ikh Primenen. (1987), No. 5, 13; (1987), No. 6, 26). It seems that here one is dealing with a reaction between the epoxy groups and the hydroxyurethane functions, since the resulting products are cross-linked. However, the cross-linking reaction - which is catalysed by organotin compounds - requires high temperatures of ca. 160 to 180°C and quite long reaction times (up to 2 hours or more). Under these very severe conditions, undesired decomposition processes of the polymeric system, e.g. a marked yellowing in the case of stoving enamels, are often observed. The known state of technology therefore offers no convenient possibility for the production of cross-linked systems from epoxide resins and carbamates, in particular hydroxyalkyl urethanes or derivatives thereof. SUMMARY OF THE INVENTION The purpose of the present invention is to eliminate this disadvantage of the state of technology and to develop a new kind of reactive resin mixture capable of cross-linking on heating, which consist of epoxides and carbamates, especially hydroxyalkyl carbamates, and can be used for production of moulded articles, or as organically dissolved or water dissolved or emulsified stoving enamels or powder enamels.

DETAILED DESCRIPTION OF THE INVENTION The organic compounds possessing at least two epoxide groups to be used according to the invention can on the one hand be low molecular weight polyfunctional epoxides, e.g. glycidyl ethers of mono- or polyfunctional alcohols or phenols, such as 1,2-ethylene glycol diglycidyl ether, 1,2- or 1,3-propylene glycol diglycidyl ether, 1,2-, 1,3- or 1,4-butanediol diglycidyl ether, neopentyl glycol diglycidyl ether, hexylene glycol diglycidyl ether, dimethylcyclohexanediol diglycidyl ether, glycerol triglycidyl ether, trimethylolpropane triglycidyl ether, pentaerythritol triglycidyl ether, pentaerythritol tetraglycidyl ether, dibromoneopentyl diglycidyl ether, sorbitol glycidyl ether, resorcinol diglycidyl ether, pyrocatechol diglycidyl ether, hydroquinone diglycidyl ether, bisphenol A diglycidyl ether, bisphenol F diglycidyl ether, bisphenol S diglycidyl ether, glycidyl esters of polyfunctional carboxylic acids such as diglycidyl adipate, diglycidyl sebacate, diglycidyl phthalate, aliphatic or cycloaliphatic epoxides such as butadiene diepoxide, vinylcyclohexene diepoxide, 3,4-epoxycyclohexylmethyl-(3,4-epoxy)-cyclohexane carboxylate (Degacure K 126, Degussa), homo- or copolymers of epoxide-containing monomers such as glycidyl acrylate, glycidyl methacrylate, diglycidyl itaconate, alkylmonoglycidyl itaconate, alkylmonoglycidyl maleate, glycidyl crotonate, butadiene monoepoxide, vinylcyclohexene epoxide, vinylstyrene epoxide, di- or triglycidyl ethers of oligomeric di- or triols such as polyoxypropylene diglycidyl ether, polyoxypropylene triglycidyl ether, polytetramethylene oxide diglycidyl ether, triglycidyl isocyanurate or polyglycidyl isocyanurate, aromatic glycidylamine derivatives such as diglycidylaniline, tetraglycidyldianiline. Polymeric substances with on average at least two epoxide groups per macromolecule can also preferably be used according to the present invention, e.g. usual condensation resins from epichlorhydrin and bisphenyl A, F or S, epoxyphenol novolaks, epoxybisphenol novolaks, polypropylene oxide diglycidyl ether, polytetramethylene oxide diglycidyl ether, polyoxypropylene triglycidyl ether, cycloaliphatic epoxide resin Degacure K 126 (Degussa). As carbamate compounds of the general formula I, according to the present invention reaction products of organic isocyanates with 1,2-glycols can be used. As isocyanates, substances with quite diverse structure can be used for this, e.g. isocyanic acid, monofunctional aliphatic isocyanates such as methyl isocyanate, ethyl isocyanate, propyl isocyanate, butyl isocyanate or cyclohexyl isocyanate, aromatic monoisocyanates such as phenyl isocyanate, naphthyl isocyanate or substituted phenyl or naphthyl isocyanates, aliphatic diisocyanates such as tetramethylene diisocyanate, hexamethylene diisocyanate, isophorone diisocyanate, 2,4,4-trimethylhexamethylene diisocyanate, cyclohexane diisocyanate or hydrogenated diphenylmethane diisocyanate, aromatic diisocyanates such as phenylene diisocyanate, toluylene diisocyanate, diphenylmethane diisocyanate, naphthalene diisocyanate or triphenylmethane triisocyanate. However conversion products of the polyfunctional isocyanates, which after the conversion still possess isocyanate groups, such as e.g. trimerised hexamethylene diisocyanate, di- or trimerised isophorone diisocyanate, biuret-modified hexamethylene diisocyanate, toluylene diisocyanate isocyanurate, toluylene diisocyanate trimethylolpropane adduct etc can also advantageously be used for the preparation of carbamate compounds of the general formula I. In the reaction of the said mono or polyfunctional isocyanates with glycols, during which carbamate compounds of the general formula I are produced, many 1,2-glycols can be used. The following can serve as examples of especially suitable compounds: ethylene glycol, 1,2-propylene glycol, 1,2-butylene glycol, 1,2-hexylene glycol, 3-chloro-1,2-propandiol, 1-phenoxy-2,3-propandiol, phenylethylene glycol, 1-allyloxy-2,3-propandiol, 1-butoxy-2,3-propandiol, glycerine monocarboxylates, such as 1-acetoxy-2,3-propandiol, 1-methacryloxy-2,3-propandiol etc. Particularly suitable in use according to the present invention as carbamate compounds of the general formula I are reaction products from ammonia, or mono-, di- or trifunctional aliphatic, aromatic or heterocyclic amines with 5-membered cyclic esters of carbonic acid. In this reaction the most diverse dioxolanones, such as e.g. ethylene carbonate, propylene carbonate, 1,2-, or 2,3-butylene carbonate, phenylethylene carbonate, can be used as cyclic carbonates. For this, it is particularly advantageous to use cyclic carbonates which can be made from the corresponding 1,2-epoxides by catalytic addition of carbon dioxide, e.g. butyloxymethylethylene carbonate, phenoxymethylethylene carbonate, allyloxymethylethylene carbonate, glycerine cyclocarbonate methacrylate, chloromethylethylene carbonate, cyclocarbonate derived from Cardura E 10 and CO 2 , etc. The selection of amines which on reaction with cyclic carbonates can give carbamate compounds of the general formula I is also really large. Particularly advantageously it is possible to use ammonia, aliphatic amines such as methylamine, ethylamine, propylamine, butylamine, cyclohexylamine, ethylenediamine, propylenediamine, butylenediamine, hexamethylenediamine, isophorone diamine, 2,2,4-trimethyl hexamethylenediamine, dodecane diamine, hydrogenated diphenylmethanediamine, phenylenediamine, toluylenediamine, diphenylmethane diamine, ethyl polyamines such as 4,9-dioxadodecan-1,12-diamine, 4,7,10-trioxatridecane-1,13-diamine, bis(3-aminopropyl)-polytetrahydrofuran, Jeffamine (proprietory product of Texaco Co.), amidoamines, such as bis-(2-aminoethyl)-adipamide, bis-(2-aminoethyl)-sebacamide etc. The use of mixtures of two or more carbamates, which are prepared according to the same or different methods, but all possess the general formula I, can be especially advantageous in the present invention. As carbamate compounds of the general formula I primary or secondary carbamates can preferably be used, e.g. HOCH 2 CH 2 -OCONH 2 , HOCH 2 -CH(CH 3 )-OCONH 2 , HOCH(CH 3 )-CH 2 -OCONH 2 , HOCH 2 CH 2 -OCONHC 2 H 5 , HOCH 2 CH 2 -OCONHCH 3 , C 6 H 5 OCH 2 -CH(OH)-CH 2 -OCONH 2 , HOCH(CH 3 )-CH 2 -OCONH-(CH 2 ) 6 -NHCOO-CH 2 CH(CH 3 )OH, C 6 H 5 OCH 2 -CH(OH)-CH 2 -OCONH-(CH 2 ) 4 -NHCOO-CH 2 CH(OH)-CH 2 OC 6 H 5 . As carbamate compounds of the general formula II, many esters or urethanes of the hydroxycarbamates of the formula HO-CH(R 1 )-CH(R 2 )-OCONHR 3 , i.e. carbamate compounds of the general formula I, where n = 1, to be regarded as alcohols, can be used. These may be derivatives of mono-, di- or tri-functional acids or isocyanates. Particularly well suited as esters (z = 0 in the general formula II) are formates, acetates, propionates, acrylates, methacrylates, crotonates, maleates, itaconates, benzoates, phenylacetates, phthalates, trimellitates, pyromellitates and cinnamates, e.g. HCOO-CH 2 CH 2 -OCONH 2 , CH 3 -COO-CH 2 CH 2 -OCONH 2 , CH 3 -COO-CH 2 CH 2 -OCONH-CH 3 , C 2 H 5 -COO-CH(CH 3 )-CH 2 -OCONH-CH 3 , CH 2 =C(CH 3 )-COO-CH 2 CH 2 -OCONH 2 , CH 2 =CH-COO-CH 2 -CH(CH 3 )-OCONH 2 , CH 3 -CH=CH-COO-CH(CH 3 )-CH 2 -OCONH 2 , CH 2 =C(COOH)CH 2 COO-CH 2 CH 2 -OCONH 2 , C 6 H 5 -COO-CH 2 CH 2 -OCONH-C 2 H 5 , HOOC-C 6 H 4 -COO-CH 2 CH 2 -OCONH 2 , C 6 H 5 -CH=CH-COO-CH(CH 3 )-CH 2 -OCONH 2 . Particularly well suited as urethanes (z = 1, p = 1 in the general formula II) are derivatives of monoisocyanates, such as methyl isocyanate, ethyl isocyanate, butyl isocyanate, hexyl isocyanate, cyclohexyl isocyanate, phenyl isocyanate, substituted phenyl isocyanates, benzyl isocyanate, naphthyl isocyanate, or even polyfunctional isocyanates, such as 1,4-tetramethylene diisocyanate, 1,6-hexamethylene diisocyanate, isophorone diisocyanate, 2,2,4-trimethylhexamethylene diisocyanate, 1,4-phenylene diisocyanate, toluylene diisocyanate, diphenylmethane diisocyanate or naphthalene diisocyanates, e.g. CH 3 -NHCOO-CH 2 CH 2 -OCONH 2 , C 4 H 9 -NHCOO-CH 2 CH 2 -OCONH-C 2 H 5 , C 6 H 11 -NHCOO-CH(CH 3 )-CH 2 -OCONH 2 , C 6 H 5 -NHCOO-CH 2 CH 2 -OCONH 2 , C 6 H 5 CH 2 -NHCOO-CH(CH 3 )-CH 2 -OCONH-CH 3 , H 2 NCOO-CH 2 CH 2 -OCONH-(CH 2 ) 4 -NHCOO-CH 2 CH 2 -OCONH 2 , CH 3 -NHCOO-CH(CH 3 )-CH 2 -OCONH-C 6 H 4 -NHCOO-CH 2 -CH(CH 3 )-OCONH-CH 3 , H 2 NCOOCH 2 CH 2 -OCONH-CH 2 C(CH 3 ) 2 CH 2 CH(CH 3 )CH 2 CH 2 -NHCOO-CH 2 CH 2 OCONH 2 . However conversion products of the polyfunctional isocyanates, which after conversion still possess free isocyanate groups, such as e.g. trimerised hexamethylene diisocyanate, di- or trimerised isophorone diisocyanate, biuret-modified hexamethylene diisocyanate, toluylene diisocyanate isocyanurate, toluylene diisocyanate-trimethylol propane adduct etc can advantageously be used for the preparation of carbamate compounds of the general formula II, e.g. The acrylate polymers according to the general formula III are copolymers of: a) at least one urethane-containing monomer, such as esters or amides of acrylic acid, methacrylic acid, itaconic acid, crotonic acid, maleic acid, e.g. CH 2 =CH-COO-CH 2 -CH(CH 3 )-OCONH 2 , CH 2 =C(CH 3 )-COO-CH 2 CH 2 -OCONH 2 , CH 3 -CH=CH-CONH-CH 2 CH 2 -NHCOO-CH 2 CH 2 -OH, CH 2 =C(COOH)CH 2 COO-CH(CH 3 )-CH 2 -OCONH-CH 3 , CH 2 =C(CH 3 )-CONH-CH 2 -O-CH 2 CH 2 -OCONH 2 , CH 2 =C(CH 3 )-COO-CH 2 CH 2 -NHCOO-CH 2 -CH(CH 3 )-OCONH 2 , CH 2 =C(CH 3 )-COO-CH 2 CH 2 -OCONH-(CH 2 ) 6 -NHCOO-CH 2 CH 2 -OCONH-CH 3 and/or at least one urethane-containing derivative of styrene or alpha-methylstyrene, e.g. CH 2 =C(CH 3 )-C 6 H 4 -C(CH 3 ) 2 -NHCOO-CH 2 CH 2 -OH, CH 2 =C(CH 3 )-C 6 H 4 -C(CH 3 ) 2 -NHCOO-CH(CH 3 )-CH 2 -OCONH-CH 3 b) at least one compound from the group of the usual monomers used in the preparation of acrylic resins, such as acrylic or methacrylic acid, optionally substituted acrylic or methacrylic esters, amides, nitriles, styrene, vinyltoluene and others, e.g. CH 2 =CH-C 6 H 5 , CH 2 =CH-COOH, CH 2 =C(CH 3 )-CONH 2 , CH 2 =CH-CN, CH 2 =C(CH 3 )-COOCH 3 , CH 2 =C(CH 3 )-COOCH 2 CH 2 -N(CH 3 ) 2 , CH 2 =CH-COOC 4 H 9 , CH 2 =C(COOC 2 H 5 )CH 2 COOC 2 H 5 . The copolymers according to general formula III are preferably prepared by radical copolymerisation. Especially well suited as initiators of the polymerisation are the known peroxide compounds, such as dialkyl peroxides, alkyl hydroperoxides, diacyl peroxides or esters of the peroxycarboxylic acids, the known azo initiators or the usual redox initiator systems. Several substances of the stated substance classes are well known as polymerisation initiators (e.g. F Runge and E Taeger "Introduction to the Chemistry and Technology of Plastics", Akademie-Verlag Berlin, 1976). The preparation of the copolymers of the general formula III can be carried out in various ways. Particularly suitable are the methods of substance or bulk polymerisation, solution, suspension or emulsion polymerisation. In the preparation of the acrylate copolymers of the general formula III by solution polymerisation, known substances are used as solvents. Especially suitable for this are such solvents as hydrocarbons (e.g. heptane, toluene, xylenes), esters (e.g. ethyl or butyl acetate, ethyl propionate), alcohols (e.g. butanol), ketones (e.g. methyl ethyl ketone, methyl isobutyl ketone), ethers (e.g. tetrahydrofuran, dioxan, ethylene glycol dimethyl, or diethyl ether, diethylene glycol dimethyl or diethyl ether), alkylglycols (e.g. methylglycol, ethylglycol, butylglycol, methyldiglycol) or glycol ether esters (e.g. ethylglycol acetate, butyldiglycol acetate, methoxypropyl acetate). Both the individual solvents and also mixtures thereof can advantageously be used in the polymerisation. The initiation of the polymerisation is effected with generally known radical generators. The polymerisation for the preparation of the copolymers of the general formula III can be performed over a broad temperature range, it being advantageous to work in the temperature range between 60°C and 180°C, and particularly beneficial in the temperature range between 80°C and 140°C. During the polymerisation the decomposition temperature of the particular carbamate used (generally ca. 140°C to 180°C) should not be exceeded. The preparation of the copolymers of the general formula III can also be effected by emulsion polymerisation. This mode of operation is especially preferred when it is desired to prepare thermosetting reactive resin mixtures according to the invention according to claim 12. Here, use is made of normal, generally known polymerisation additives frequently used in emulsion polymerisation, for example emulsifiers, water-soluble or water-insoluble polymerisation initiators, emulsion stabilisers, chain length regulators, buffer systems, cross-linking agents, defoamers or preservatives. The preparation of the copolymers of the general formula III by emulsion polymerisation can be effected either in the presence or the absence of emulsifiers. Suitable for this are many generally known emulsifiers (e.g. I Piirma (Ed.) Emulsion Polymerisation, Academic Press, 1982, 221-245), which can be either cationic, anionic or even non-ionic in nature. The quantities of the individual reaction components in the preparation of the copolymers of the general formula III by emulsion polymerisation can be varied over a wide range, so that the polymer content of the emulsions obtained lies between 5 and 85 wt %, advantageously between 30 and 60 wt %. The preparation of the copolymers of the general formula III by emulsion polymerisation can be effected over a wide temperature range. Depending on the activity of the initiator system used and of the emulsifier or emulsifier mixture used, the emulsion polymerisation can take place between 0°C and 100°C, preferably between 20°C and 80°C. Addition of small quantities of organic solvents can have an advantageous effect on the emulsion polymerisation for the preparation of the copolymers of the general formula III, especially during the subsequent use of the aqueous emulsions obtained for the preparation of the thermosetting reactive resin mixtures according to claim 3 and in the use of these reactive resin mixtures according to the invention in the coatings or paints sector. A variant of the preparation of copolymers of the general formula III of particular interest in relation to the subsequent use of the thermosetting reactive resin mixtures according to the invention is that whereby, together with one or more carbamate-containing monomers and other monomers normally useable in emulsion polymerisation in water, substances of basic or acidic character (e.g. substituted aminoalkyl acrylates, unsaturated acids, vinylpyridine, etc) are polymerised in. In this way storage-stable aqueous emulsions can be prepared, which contain copolymers of the general formula III and can be used for the preparation of the thermosetting reactive resin mixtures according to claim 3 of the invention in aqueous emulsion. The binders present in these emulsions - after complete or partial neutralisation - are electrically precipitable and can be used for the preparation of electrophoretic enamels. The molecular weight of the acrylic copolymers according to the general formula III can be regulated by known methods, especially by the use of regulators. Especially suitable are known regulators based on mercaptans, such as dodecylmercaptans, mercaptoethanol, and derivatives of mercaptoacetic or mercaptopropionic acid. The polymers of the general formula IV are reaction products from epoxy resins and reactive carbamate compounds, which in addition to the urethane groups also possess in addition a primary or secondary amine group or a carboxyl function. These carbamate compounds are readily accessible by the reaction of aliphatic polyamines with stoichiometric proportions or a lesser proportion of 2-oxo-1,3-dioxolanes, based on the primary amine groups. Examples are the following products H 2 N-CH 2 CH 2 NHCOO-CH 2 CH 2 -OH, HO-CH 2 CH 2 NH-CH 2 CH 2 -NHCOO-CH(CH 3 )CH 2 -OH, H 2 N-(CH 2 ) 6 -NHCOO-CH 2 -CH(CH 3 )-OH. Carbamates which as well as the urethane function carry a carboxyl group can very easily be synthesised by the reaction of hydroxyalkyl carbamates of the general formula I (where n = 1) with a cyclic dicarboxylic acid anhydride. In this way compounds such as the following are formed H 2 NCOO-CH 2 CH 2 -OCOCH 2 CH 2 -COOH, HOOC-C 6 H 4 -COOCH(CH 3 )CH 2 -OCONH 2 , HOOC-(CH 2 ) 3 -COO-CH 2 CH 2 -OCONH-CH 3 . These reactive carbamate compounds are linked to the epoxide groups of the epoxide resins via the amine or carboxyl function. The reaction of the amine groups with the oxirane function here proceeds readily at room temperature, while the reaction between carboxyl and epoxide groups requires an elevated temperature and the use of known catalysts (e.g. amines, quaternary ammonium salts, phosphines, Lewis acids etc). The polymers of the general formula IV formed in the reactions have for example the following structure: HO-CH 2 CH 2 OCONH-CH 2 CH 2 -N(CH 2 CH 2 OH)CH 2 CH(OH)CH 2 O-C 6 H 4 - -C(CH 3 ) 2 -C 6 H 4 -OCH 2 CH(OH)CH 2 N(CH 2 CH 2 OH)CH 2 CH 2 -NHCOO- -CH 2 CH 2 -OH [CH 3 -NHCOO-CH 2 CH 2 -OCOCH 2 CH 2 CH 2 COOCH 2 CH(OH)CH 2 O-C 6 H 4 -] 2 - -C(CH 3 ) 2 CH 3 -NHCOO-CH 2 CH 2 -OCOCH 2 CH 2 CH 2 COOCH 2 CH(OH)CH 2 -[O-C 6 H 4 - -C(CH 3 ) 2 -C 6 H 4 -OCH 2 CH(OH)CH 2 O-] 1-10 COCH 2 CH 2 CH 2 - -COOCH 2 CH 2 -OCONH-CH 3 A further group of polymers of the general formula IV is represented by the products of the reaction of polymers containing terminal dioxolanone groups (obtained from epoxide resins for example according to DE-OS 35 29 263, or DE-OS 37 23 782) with ammonia or amines. The polymers of the general formula IV thus formed have for example the following structure: H 2 NCOO-CH 2 CH(OH)CH 2 -[O-C 6 H 4 -C(CH 3 ) 2 -C 6 H 4 -OCH 2 CH(OH)- -CH 2 O-] 1-10 -CONH 2 CH 3 NHCOOCH 2 CH(OH)CH 2 -[O-C 6 H 4 C(CH 3 ) 2 -C 6 H 4 -OCH 2 CH(OH)- -CH 2 O-] 1-10 -CONHCH 3 For the preparation of thermosetting reactive resin mixtures according to the invention, the use of basic catalysts is necessary. Advantageously aliphatic amines can be used for this, such as for example ethylhexylamine, dibutylamine, triethylamine, tributylamine, triethanolamine, heterocyclic amines such as 1,4-diazabicyclo-(2,2,2)-octane, 4-(dimethylamino)-pyridine, imidazoles, such as 2-ethyl-4-methylimidazole, amidines, such as 1,5-diaza-bicyclo(4,3,0)-non-5-ene, 1,8-diazabicyclo(5,4,0)-undec-7-ene, guanidines, such as 1,1,3,3-tetramethylguanidine, quaternary ammonium compounds such as tetramethylammonium hydroxide, benzyltrimethylammonium hydroxide, tetraethylammonium fluoride, benzyl triethylammonium chloride, tetraethylammonium iodide, hydroxides and alcoholates of the alkali metals, such as sodium hydroxide, sodium methoxide, potassium tert.-butylate etc. It can also be advantageous to use mixtures of two or of several suitable catalysts. The cross-linking taking place in the thermosetting reactive resin mixtures according to the invention at increased temperature relies on a reaction between the oxirane groups of the epoxide compounds used and the urethane groups of the carbamates used of the general formulae I, II, III or IV. In order to cause this cross-linking reaction to occur in the thermosetting reactive resin mixtures, it is necessary that both reactive components - the epoxide and the carbamate compound(s) - are present in a defined quantity ratio. Here it is exclusively the mole ratio of the reacting groups which is important. The reactive resin mixtures according to the invention can easily be thermally set when the mole ratio of the carbamate/oxirane reactive groups is between 20:1 and 1:20, advantageously between 5:1 and 1:5, preferably between 3:1 and 1:3 and especially between 2:1 and 1:2. The thermosetting reactive resin mixtures according to the present invention essentially consist of: at least one organic compound possessing at least 2 epoxide groups at least one carbamate compound of the general formulae I, II, III or IV and at least one basic catalyst. The thermosetting reactive resin mixtures according to the invention are prepared by mixing of these three components, if necessary with heating to temperatures up to ca. 120°C. In many cases - particularly when low molecular weight epoxide compounds are used - no compatibility problems of any kind are observed, so that the said components can be mixed as such. In this way mixtures which are solvent-free are obtained. The mixtures obtained are clear and homogeneous; their viscosity mainly depends on the melting or softening temperatures of the components used. Above the softening temperature, the mixtures are in most cases of relatively low viscosity. A mixture of the said components in suitable quantity ratios also forms a thermosetting reactive resin mixture according to the present invention without the use of further additives. In relation to application technology considerations, it can however be advantageous to use processing aids and/or additives when using the reactive resin mixtures according to the invention. These can be such substances as solvents, reinforcing materials, levelling agents, light stabilisers, dyestuffs, pigments, pigment pastes, fillers, plasticisers, fragrances or flavourings, bactericides, fungicides, antioxidants, stabilisers, anticorrosion agents, propellants, surfactants, thickeners, reactive diluents and neutralising substances etc. These additives, which are for example very well-known and frequently used in the paint industry, can if necessary be added to the reactive resin mixtures of the invention directly before processing. Suitable fillers which may be mentioned are: chalk, talc, kaolin, powdered quartz, slate flour, silicic acids, aluminium oxides etc. Suitable plasticisers are for example dioctyl phthalate, dioctyl adipate, dibutyl sebacate, triphenyl phosphate etc. The simultaneous use of reinforcing materials during the processing of the reactive resins according to the invention is also possible. As examples of such materials, glass fibers or glass fabric may be cited. As dyestuffs or pigments, which can be of an inorganic or organic nature, the following are named for example: titanium dioxide, soot, zinc chromate, barium chromate, lead chromate, zinc oxide, iron oxide pigments, phthalocyanine pigments, ultramarine blue, naphthol red, etc. The thermosetting reactive resin mixtures according to the invention can be diluted with a solvent. In this way the compatibility problems occurring in some cases with the resin mixtures of to the invention can be overcome; secondly in this way the processing technology properties can be improved, e.g. the viscosity of a paint formulation can be decreased or the flow of the applied paint improved. Many solvents can be added to the thermosetting reactive resin mixtures according to the present invention. Particularly suitable for this are aliphatic or aromatic optionally halogen-substituted hydrocarbons such as methylene chloride, chloroform, carbon tetrachloride, dichloroethane, hexane, cyclohexane, benzene, toluene, xylenes, chlorobenzene, dichlorobenzenes, technical solvent mixtures such as petrol fractions, aromatics mixtures (Solvesso or Shellsol types), ethers such as diethyl ether, ethylene glycol dimethyl ether, ethylene glycol diethyl ether, diethylene glycol dimethyl ether, dipropylene glycol diethyl ether, tripropylene glycol dimethyl ether, tetrahydrofuran, dioxane, ketones, such as acetone, methylethyl ketone, methyl isobutyl ketone, diethyl ketone, cyclohexanone, alcohols, such as methanol, ethanol, propanols, butanols, ethylhexanol, ethylene glycol, propylene glycol, glycol monoalkyl ethers, such as methylglycol, ethylglycol, butylglycol, methoxypropanol, ethoxypropanol, methyldiglycol, ethyldiglycol, butyldiglycol, dipropylene glycol monomethyl ether, esters such as ethyl acetate, butyl acetate, ethyl propionate, methylglycol acetate, ethylglycol acetate, methoxypropyl acetate, ethyldiglycol acetate, amides, such as dimethylformamide, dimethylacetamide, dioxolanones, such as ethylene or propylene carbonate, N-methylpyrrolidone, dimethylsulphoxide and others. Here the solvents can be used alone or mixed, latter especially when the solvent power of the individual solvent is insufficient on account of too low a polarity. Depending on the proportion of the solvent used, solutions of thermosetting reactive resin mixtures with different solids contents can be prepared. In order to minimise environmental impace due to evaporation of the solvents, solutions are preferred which possess a solids content between 20 and 99 wt %, advantageously between 30 and 98 wt %, preferably between 50 and 97 wt % and especially between 60 and 95 wt %. Use of monofunctional reactive diluents, which are usual in the field of epoxy paints, can likewise result in elimination of the incompatibility which may arise with the thermosetting reactive resin mixtures. In such cases it is possible under some circumstances to dispense with the use of volatile solvents completely. As reactive diluents, the following compounds can for example be used (up to 10-15 wt % based on the solid resin): phenyl glycidyl ether, p-tert.-butylphenyl glycidyl ether, Cardura E10 (Shell) or ethylhexyl glycidyl ether. The pot lives of the solvent-containing or reactive diluent containing thermosetting reactive resin mixtures of the invention as a rule are several months. Thus these are typical one-component systems. From the point of view of environmental acceptability, aqueous systems containing thermosetting reactive resin mixtures are of particular interest. These can be prepared by mixing of an aqueous emulsion or an aqueous solution of at least one carbamate compound of the general formulae I, II, III or IV with an aqueous emulsion or an aqueous solution of at least one organic compound containing at least two epoxide groups and at least one suitable catalyst. If individual components of the thermosetting reactive resin mixtures of the invention are water-soluble, it is also possible to add such components as such (i.e. undissolved) to the aqueous emulsion or to the aqueous solution of other components. This applies above all for carbamate compounds of the general formula I or II, which are often water soluble, e.g. CH 3 COO-CH 2 -CH 2 -OCONH 2 , HO-CH 2 -CH 2 -OCONH 2 , HO-CH 2 -CH(CH 3 )-OCONH 2 , HO-CH(CH 3 )-CH 2 -OCONH 2 , CH 3 -NHCOO-CH 2 -CH 2 -OCONH 2 . However it can also be advantageous for processing technology if the aqueous systems of the thermosetting reactive resin mixtures of the invention also contain small quantities (up to ca. 10-15 wt % based on the solid resin) of organic solvents. In general these are additives which increase the emulsion stability, facilitate film formation after application of the thermosetting reactive resin mixtures, improve the flow of the coatings, improve the evaporative behaviour of the volatile components or are capable of favourably affecting other application-related properties. The processing of the liquid thermosetting reactive resin mixtures of the invention as coating materials can be effected by usual methods, such as by painting, doctor application, spraying, rolling, casting or stamping. Preferable is processing by paint spraying by the many known means, e.g. with air pressure pistols or on an electrostatic plant. With the appropriate structure of the thermosetting reactive resin mixtures of to the invention, electrophoretic enamelling can be the preferred processing method. The application of the electrophoretic enamels is effected by known methods. After application, the reactive resin mixtures are then hardened by stoving, to produce the coatings according to the invention. These are distinguished by outstanding water and chemicals resistance and great hardness with, at the same time, remarkable elasticity. The surface quality of the cross-linked coatings is very good, the paints are high-gloss and transparent and show outstanding adhesion on different substrates. The outstanding properties of the paints - in particular their excellent resistance to chemicals and weathering - make it possible to use the thermosetting reactive resin mixtures of the invention successfully for the production of automobile paints, preferably automobile coating paints. The hardening of the thermosetting reactive resin mixtures of the invention takes place at temperatures between 80°C and 240°C, preferably between 100°C and 180°C, especially between 120°C and 160°C. The stoving times are normally determined on the basis of the chosen hardening temperature and generally total 20 to 30 minutes at 120-140°C. However these times can be substantially reduced if one works at higher oven temperatures (e.g. 10 min at ca. 180°C). On the other hand it can be advantageous to harden the coatings at lower temperatures - in such cases it is necessary to reckon with longer stoving times (up to 2 hours). A further application variant, which it is preferable to use for the sake of environmental acceptability is the use of solid thermosetting reactive resin mixtures. If these are mixtures which have a softening temperature higher than 60°C, they can be dry-milled without difficulty. The powders so obtained can be prepared without addition of solvents and hence contain practically no volatile components. A preferred use field for such powder thermosetting reactive resin mixtures is powder coating. A further possible way of preparing thermosetting reactive resin mixtures useable as cross-linkable powder paints consists in completely removing the solvent from a solvent-containing mixture. This is preferably accomplished by vacuum distillation. The solid mixtures so obtained can - optionally after addition of other processing aids and additives, such as pigments, rheological processing aids, conductivity improvers etc - be melted and mixed at increased temperature, e.g. in an extruder. After subsequent cooling these mixtures can be ground. Suitable epoxide compounds for this are for example bisphenol-A-based epoxide resins solid at room temperature, such as Epotuf 001, 002 and 004 (Reichold Chemie) or glycidyl methacrylate copolymers with appropriately high glass transition temperature, such as for example Finedic A-224S (Dainippon Ink & Chemicals). The coating powders are applied in the known way by electrostatic powder spraying. The thermosetting reactive resin mixtures of the invention applied in this way are cross-linked by stoving, the stoving conditions for this being similar to those for conventionally applied lacquers. A further application variant for the coating powders involves a subsequent wet milling of the powder obtained in water. If this process is performed for long enough, stable powder suspensions are formed, which can be applied and hardened in a comparable way to the aqueous thermosetting reactive resin mixtures obtained by conventional methods - already described above. The thermosetting reactive resin mixtures of the invention represent a considerable advance compared with the epoxide resin systems which are known from the state of technology. The mixtures described in the present invention are stable at least for several months at room temperature, but cross-link at raised temperature considerably more quickly than other one-component systems. As regards environmental acceptability, the thermosetting reactive resin mixtures according to the invention also offer considerable advantages, compared with other epoxide-based resin systems which are known from the state of technology. Thus the carbamate compounds of the general formulae I, II, III or IV are practically non-volatile, and hence less environmentally harmful than for example the readily volatile aliphatic amines, which also often have a toxic action. The low volatility of the said carbamates, practically negligible during industrial use, also represents an advantage compared with acid anhydrides, which are also quite often used for the hardening of epoxide resins. It is well known that the low molecular weight carboxylic acid anhydrides tend to sublime during the stoving process. This leads to significant technological problems, but also causes injury to health. A further advantage of the thermosetting reactive resin mixtures of the invention compared with for example anhydride-setting epoxide resin systems is due to the resistance of the carbamate compounds of the general formulae I, II, III and IV to hydrolysis. Hence the resin mixtures of the invention can also be used in aqueous media. This represents firstly an extension of the application fields for the said thermosetting reactive resin mixtures, and secondly at the same time a significant decrease in environmental impact. The simplification of the storage of the non-moisture sensitive resins of the invention also contributes significantly to the superiority of the crosslinking system presented. An additional significant advantage of the thermosetting reactive resin mixtures compared with for example anhydride- or acid-setting epoxide resin systems is due to the very good compatibility of the carbamate compounds of the general formulae I, II, III and IV with commonly used epoxide resins. Consequently compatibility problems scarcely arise with the setting resin mixtures described in the present invention, so that the formulated - solvent-containing - paint systems often have solids contents of 80-90 wt % or even higher. A consequence of this is a remarkably low environmental impact due to evaporation of the solvent. The thermosetting reactive resin mixtures of the invention are therefore outstandingly suitable for the production of high-solids paint systems. The carbamate compounds of the general formulae I, II, III and IV, which are essential components of the mixtures, are often synthesised from the low priced alkaline carbonates, such as ethylene or propylene carbonate. Consequently the production costs of the resin mixtures described in the present invention are very low. Surprisingly it is then found that by the use of basic catalysts according to the invention a considerable decrease in the stoving temperature with a simultaneous shortening of the hardening times compared with described systems - e.g. V V Mikheev et al. (Lakokras. Mater. Ikh Primenen. (1987), No. 5, 13; (1987), No. 6, 26) - can be achieved. It is also surprising that the thermosetting reactive resin mixtures of the invention can be formulated using primary aliphatic carbamates. From the knowledge according to the state of technology (especially J. Org. Chem. 29, (1964) 379; J Polym. Sci. A-14, (1966) 751; Sintez i fiziko-chimija polimerow 7, (1970) 42; 8, (1971) 45) particular unreactivity is to be expected for just this class of substances. Thermosetting reactive resin mixtures according to the invention which contain monofunctional urethanes as carbamate compounds according to the general formulae I or II, such as e.g. HOCH 2 CH(CH 3 )OCONH 2 , HOCH 2 CH 2 OCONH 2 , HOCH(CH 3 )CH 2 OCONH 2 or CH 3 COOCH 2 CH 2 OCONH 2 , must be regarded as particularly surprising. Thus polyfunctionality of the carbamates is not an absolute requirement for the cross-linking of the thermosetting reactive resin mixtures. The outstanding properties of the moulded articles or coatings which can be produced from the thermosetting reactive resin mixtures of the invention are also very surprising. Even using short-chain carbamates of the general formulae I or II, such as e.g. CH 3 COOCH 2 CH 2 OCONH 2 or HOCH(CH 3 )CH 2 OCONH 2 , mixtures with bisphenol-A diglycidyl ether yield hard, and at the same time elastic, cross-linked coatings. The cross-linking systems based on bisphenol-A diglycidyl ether known from the state of technology display a marked brittleness, which has to be compensated by the use of special elasticising cross-linkers. The coatings obtained by stoving of the thermosetting reactive resin mixtures of the invention display a very good adhesion to different substrates. This is also the reason why the resin mixtures of the invention are outstandingly suitable for the production of thermosetting adhesives. The thermosetting reactive resin mixtures can further be used for the production of moulded articles. Typically, the hardening of the moulded articles takes place between 100°C and 240°C, preferably between 120°C and 200°C and especially between 140°C and 180°C. After the initial hardening phase of ca. 4-8 hours, which may possibly be sufficient, it is often advantageous to subject the moulded articles obtained to an additional afterhardening. This is performed between 140°C and 300°C, preferably between 160°C and 260°C and especially between 180°C and 240°C. The typical afterhardening times are ca. 6 to 24 hours, preferably 10 to 16 hours. The moulded articles obtained from the reactive resin mixtures of the present invention display very good mechanical and electrical properties. Consequently the thermosetting reactive resin mixtures of the invention can preferably be used as moulding compounds for the production of electrical components, such as printed circuits, and electronic equipment, such as pocket calculators, computers, clocks, cameras etc. The thermosetting reactive resin mixtures of the invention can also be used for the production of soaking and impregnating compounds for electrical insulators or laminated composites or for glass- or carbon fibre-reinforced laminates. In this way composite materials with outstanding electrical, mechanical and thermal properties are obtained. Insulating materials for electric motors or generators can advantageously also be produced using the thermosetting reactive resin mixtures of the invention, as can the production of highly thermally or mechanically stressed construction materials for aircraft components or space-ships. In addition, the thermosetting reactive resin mixtures can be used as moulding resins in the production of containers, tubes and sports equipment, such as skis, surfboards, boats etc. With the use of suitable propellants, the thermosetting reactive resins of the invention can also be used for the preparation of foamed materials. EXAMPLES The invention is illustrated in more detail by the following examples. Unless otherwise stated, all quantities given are based on parts by weight. The solvent resistance of the coatings obtained from the thermosetting reactive resin mixtures of the invention is tested by rubbing the coated surface with a wad soaked in methyl ethyl ketone. A hardened coating is described as solvent-resistant if practically no traces can be seen on the surface after 75 double strokes. The hardness of the stoved coatings is expressed as the pendulum hardness values measured (according to DIN 53175). The elasticity of the coatings obtained after stoving is qualitatively assessed by bending the coated plate to an angle of 180° and observing any white-break which may occur. Those coatings which show no white-break and no flaking are described as elastic. N-substituted or unsubstituted 2-hydroxyalkyl carbamates, such as e.g. HOCH 2 CH(CH 3 )OCONH 2 , HOCH 2 OCONH 2 , HOCH(CH 3 )CH 2 OCONH 2 , HOCH 2 CH 2 OCONHCH 3 , etc. are prepared by known methods (e.g. P Adams and F A Baron, Chem. Reviews 65 (1965) 567). By hydroxypropylcarbamate is meant HOCH 2 CH(CH 3 )OCONH 2 , HOCH(CH 3 )CH 2 OCONH 2 or a mixture of these two primary urethanes.
