     The invention relates to novel derivatives of α-aminoacetophenone which have an allyl or aralkyl group in the α-position, and to their use as photoinitiators for the photopolymerization of ethylenically unsaturated compounds, in particular for photocuring pigmented systems, such as printing inks or white lacquer. 
     Derivatives of α-aminoacetophenone are known from EP-A-3,002 as photoinitiators for ethylenically unsaturated compounds. If these compounds have in their 4-position of the phenyl radical substituents containing sulfur or oxygen, the compounds are particularly suitable as photoinitiators for pigmented photocurable systems (EP-A-88,050 and 117,233), for example for UV-curable printing inks. 
     Derivatives of α-aminoacetophenone which have an amino group in the 4-position of the phenyl radical are described in EP-A-138,754. These compounds are used in combination with photosensitizers from the aromatic carbonyl compound class. 
     It has now been found that of this general class of α-aminoacetophenones, those which contain at least one alkenyl or aralkyl group in the α-position have a particularly high activity as photoinitiators. These compounds are especially suitable for use in printing inks.

     In most of these compounds, R 1  --or R 1  and R 2  --is a substituent of the allyl or benzyl type. The synthesis of such compounds usually includes C-allylation or C-benzylation. The amino group --NR 3  R 4  is preferably introduced before the allylation/benzylation. The synthesis is then carried out in the following sequence of reaction steps: ##STR15## 
     The starting ketones are known compounds which can be prepared, for example, by a Friedel-Crafts reaction. Reaction steps 1 and 2 are known reactions which are described in more detail, for example, in EP-A-3,002. The two reactions can be carried out one after the other without isolating the bromoketone. 
     Reaction 3 is described in detail below. In the case of C-allylation, it can proceed via the enol allyl ether as an intermediate in the sense of Claisen rearrangement. In the case of C-benzylation or C-allylation, this can proceed via a quaternary benzylammonium salt or allylammonium salt as an intermediate in the sense of a Stevens rearrangement. In both cases, however, the intermediate is not isolated. If both R 1  and R 2  are allyl or benzyl groups, the above reaction sequence is started with an aryl methyl ketone Ar 1  --CO--CH 3  and reaction 3 is carried out twice, using R 1  Hal once and R 2  Hal once. 
     If the aromatic radical Ar 1  carries substituents which are not inert towards reactions 1, 2 or 3, the synthesis is carried out with an auxiliary substituent which is converted into the desired substituent in a subsequent step 4. For example, the syntheses can be carried out with a nitroaryl compound and this can then be reduced to the corresponding amino compound. Alternatively, the synthesis is started with a halogenoaryl compound and the halogen is then replaced by --OR 18 , --SR 19  or --NR 20  R 21  in a nucleophilic replacement reaction. A group --SR 19  can then be oxidized to --SO--R 19  or --SO 2  --R 19 . 
     For synthesis of compounds of the formula II, a primary amine R 11  NH 2  or a secondary diamine R 11  --NH--R 12  --NH--R 11  or piperazine is used in reaction stage 2 and reaction 3) and if appropriate 4) are subsequently carried out. 
     For synthesis of compounds of the formula III, a bis-aryl ketone of the formula 
     
         Ar.sup.1 --CO--CH.sub.2 --Y--CH.sub.2 --CO--Ar.sup.1 
    
     is used as the starting substance and is subjected to reactions 1, 2 and 3. 
     If R 1  is a substituent of the vinyl type, such compounds can be prepared from the corresponding allyl compounds by a catalyzed double bond isomerization. If R 1  is a substituent of the formula ##STR16## this is introduced in the same way as an allyl radical using a halogen compound of the formula ##STR17## 
     Another possibility for the synthesis of compounds of the formula I is reaction of an α-aminonitrile with an aryl-lithium compound and subsequent hydrolysis: ##STR18## 
     Such reactions have been described, for example, by Cromwell and Hess in J. Am. Chem. Soc. 83, 1237 (1961). The α-aminonitriles are accessible directly by Strecker synthesis from R 1  --CO--R 2 , or can be prepared by allylation or benzylation of an α-aminonitrile NC--CHR 2  --NR 3  R 4 . The allylation of α-aminonitriles is described, for example, by T. S. Stevens in J. Chem. Soc. 1930, 2119. 
     Compounds of the formula I in which R 1  and R 2  together with the C atom to which they are bonded form a cycloalkene ring can be prepared analogously by reaction of aryl-lithium compounds with the corresponding cyclic nitriles. The cyclic nitriles can be obtained by cyclo-addition of α-aminoacrylonitriles onto 1,3-dienes, such as has been described, for example, by Brucher and Stella in Tetrahedron 41, 875 (1985): ##STR19## 
     Finally, there is also the possibility of reacting the α-bromoketones with a tertiary allyl- or benzylamine and subjecting the quaternary salt formed to a Stevens rearrangement: ##STR20## 
     According to the invention, the compounds of the formula I, II and III can be used as photoinitiators for photopolymerization of ethylenically unsaturated compounds or mixtures containing such compounds. The unsaturated compounds can contain one or more olefinic double bonds. They can be of low molecular weight (monomeric) or of higher molecular weight (oligomeric). Examples of monomers with a double bond are alkyl acrylates or methacrylates or hydroxyalkyl acrylates or methacrylates, for example methyl, ethyl, butyl, 2-ethylhexyl or 2-hydroxyethyl acrylate, isobornyl acrylate and methyl or ethyl methacrylate. Further examples of these are acrylonitrile, acrylamide, methacrylamide, N-substituted (meth)acrylamides, vinyl esters, such as vinyl acetate, vinyl ethers, such as isobutyl vinyl ether, styrene, alkyl- and halogenostyrenes, N-vinylpyrrolidone, vinyl chloride or vinylidene chloride. 
     Examples of monomers with several double bonds are the diacrylates of ethylene glycol, propylene glycol, neopentylglycol, hexamethylene glycol or bisphenol A, 4,4&#39;-bis(2-acryloyloxyethoxy)diphenylpropane, trimethylolpropane triacrylate, pentaerythritol triacrylate or tetra-acrylate, vinyl acrylate, divinylbenzene, divinyl succinate, diallyl phthalate, triallyl phosphate, triallyl isocyanurate and tris-(2-acryloyloxyethyl)isocyanurate. 
     Examples of higher molecular weight (oligomeric) polyunsaturated compounds are acrylated epoxy resins, acrylated polyethers, acrylated polyurethanes and acrylated polyesters. Further examples of unsaturated oligomers are unsaturated polyester resins, which are usually prepared from maleic acid, phthalic acid and one or more diols and have molecular weights of about 500 to 3000. Such unsaturated oligomers can also be called prepolymers. 
     Two-component mixtures of a prepolymer with a polyunsaturated monomer or three-component mixtures which additionally also contain a mono-unsaturated monomer are frequently used. The prepolymer here is primarily decisive for the properties of the lacquer film, and by varying It the expert can influence the properties of the cured film. The polyunsaturated monomer functions as crosslinking agents which render the lacquer film insoluble. The monounsaturated monomer functions as reactive diluents, with the aid of which the viscosity is reduced without having to use a solvent. 
     Such two- and three-component systems based on a prepolymer are used both for printing inks and for lacquers, photoresists or other photocurable compositions. One-component systems based on photocurable prepolymers are frequently also used as binders for printing inks. 
     Unsaturated polyester resins are usually used in two-component systems together with a monounsaturated monomer, preferably with styrene. Specific one-component systems, for example polymaleimides, polychalcones or polyimides, such as are described in DE-OS 2,308,830, are often used for photoresists. 
     The unsaturated compounds can also be used as a mixture with non-photo-polymerizable film-forming components. These can be, for example, polymers which dry by physical means and solutions thereof in organic solvents, for example nitrocellulose or cellulose acetobutyrate. They can also be, however, resins which can be cured chemically or thermosetting resins, for example polyisocyanates, polyepoxides or melamine resins. The joint use of thermosetting resins is of importance for use in so-called hybrid systems which are photopolymerized in a first stage and crosslinked by thermal after-treatment in a second stage. 
     The photopolymerizable mixtures can contain various additives in addition to the photoinitiator. Examples of these are thermal inhibitors for the purpose of preventing premature polymerization, for example hydroquinone or sterically hindered phenols. Copper compounds, phosphorus compounds, quaternary ammonium compounds or hydroxylamine derivatives, for example, can be used to increase the storage stability in the dark. Paraffin or similar waxy substances which migrate to the surface at the start of polymerization can be added for the purpose of excluding atmospheric oxygen during the polymerization. UV absorbers, for example those of the benzotriazole, benzophenone or oxalanilide type, can be added in a small amount as light stabilizers. The addition of light stabilizers which do not absorb UV light, for example sterically hindered amines (HALS), is even better. 
     In certain cases, it may be advantageous to use mixtures of two or more of the photoinitiators according to the invention. Mixtures with known photoinitiators can, of course, also be used, for example mixtures with benzophenone, acetophenone derivatives, benzoin ethers or benzil ketals. 
     Amines, for example triethanolamine, N-methyl-diethanolamine, ethyl p-dimethylaminobenzoate or Michler&#39;s ketone, can be added to accelerate the photopolymerization. The effect of the amines can be intensified by addition of aromatic ketones of the benzophenone type. 
     Acceleration of the photopolymerization can furthermore be effected by addition of photosensitizers which shift or extend the spectral sensitivity. These are, in particular, aromatic carbonyl compounds, for example derivatives of benzophenone, thioxanthone, anthraquinone and 3-acylcoumarin, and 3-(aroylmethylene)-thiazolines. 
     The effectiveness of the photoinitiators according to the invention can be increased by addition of titanocene derivatives with fluoro-organic radicals, such as are described in EP-A-122,223 and 186,626, for example in an amount of 1-20%. Examples of such titanocenes are bis(methylcyclopentadienyl)-bis(2,3,6-trifluorophenyl)-titanium, bis-(cyclopentadienyl)-bis-(4-dibutylamino-2,3,5,6-tetrafluorophenyl)-titanium, bis(methylcyclopentadienyl)-2-(trifluoromethyl)phenyltitanium isocyanate, bis(cyclopentadienyl)-2-(trifluoromethyl)phenyltitanium trifluoroacetate and bis-(methylcyclopentadienyl)-bis(4-decyloxy-2,3,5,6-tetrafluorophenyl)-titanium. Liquid α-aminoketones are especially suitable for these mixtures. 
     The photocurable compositions according to the invention can be used for various purposes. Their use in pigmented or coloured systems, for example for printing inks, for photographic reproduction processes, for image recording processes and for producing relief forms, is of particular importance. 
     Another important field of use are paints, which can be pigmented or non-pigmented. The mixtures are particularly useful in white lacquers, by which is understood paints pigmented with TiO 2 . Other fields of use are radiation-curing of photoresists, photocrosslinking of silver-free films and production of printing plates. Another use is for external paint films which subsequently harden on their surface in daylight. 
     The photoinitiators are advantageously used in amounts of 0.1 to 20% by weight, preferably about 0.5 to 5% by weight, based on the photopolymerizable composition, for the fields of use listed. 
     The polymerization is carried out by the known methods of photopolymerization by irradiation with light rich in short-wavelength radiation. Suitable light sources are, for example, medium-pressure, high-pressure and low-pressure mercury lamps, superactinic tubular lamps and metal halide lamps or lasers with emission maxima in the range between 250 and 450 nm. In the case of combination with photosensitizers or ferrocene derivatives, light of longer wavelengths or laser beams up to 600 nm can also be used. 
     The preparation and use of the photoinitiators according to the invention are described in more detail in the following examples. In these, parts are parts by weight, percentages are percentages by weight and the temperature is given in degrees Celsius.

Neutralization of the reaction mixture is carried out with 160 ml of 30% NaOH (1.2 mol). The crude product is likewise isolated as in F). The reaction product is a yellowish oil which can be used without further purification for the next stage (amination of the nucleus). 
     NMR (CDCl 3 ): 8.53-8.1 m (2H, H B ), 7.2-6.7 m (2H, H A ), 6.1-4.7 m (6H, H olefin ), 2.8-2.5 m (4H, H allyl ), 2.4s (6H, N--CH 3 ). 
     EXAMPLE 5: Synthesis of 3,6-Dibutyryl-9-butyl-9H-carbazole 
     H) Synthesis of N-butylcarbazole 
     A suspension of 100 g (0.6 mol) of carbazole in 200 ml of toluene is heated under reflux, with stirring. After cooling to 95°, first 6.8 g (0.12 mol) of triethylbenzylammonium chloride and then a solution of 169.8 g of KOH in 180 ml of water are added. The temperature thereby drops to 65°. 205.6 g (1.5 mol) of butyl bromide are now added in the course of 5 minutes, with vigorous stirring, whereupon the temperature rises to 92°. The mixture is kept under reflux for a further 10 minutes, all the carbazole dissolving. The aqueous phase is then removed. The toluene phase is washed with a little water, dried over Na 2  CO 3  and evaporated in vacuo. The oily residue is dissolved in 300 ml of warm hexane and the solution is clarified. On cooling, the product crystallizes in beige-coloured crystals of melting point 50°-52°. 
     I) Friedel-Crafts Reaction 
     46.9 g (0.44 mol) of butyryl chloride are added dropwise to a suspension of 93.3 g (0.7 mol) of AlCl 3  in 100 ml of methylene chloride in the course of 30 minutes, while stirring and cooling to -10° to -5°. A solution of 22.3 g (0.1 mol) of N-butylcarbazole in 50 ml of CH 2  Cl 2  is then added dropwise at -10° to -5° in the course of 2 hours. The suspension is stirred at 0° to 20° for 16 hours and then poured onto ice. The emulsion formed is extracted twice with CHCl 3  and the extract is washed with water:, dried over MgSO 4  and evaporated. The crude 3,6-dibutyryl-9-butyl-9H-carbazole is re-crystallized from 80 ml of ethanol. The resulting crystals have a melting point of 107°-109°. 
     3,6-Dipropionyl-9-butyl-9H-carbazole, which has a melting point of 142°-144°, is obtained in an analogous manner from 81.4 g of propionyl chloride and 44.7 g of N-butylcarbazole. 
     The products listed in the following tables are prepared analogously to the general Preparation Examples A-I.

     EXAMPLE 5: Photocuring of a Blue Printing Ink 
     A blue printing ink is prepared in accordance with the following formulation: 
     62 parts of Setalin® AP 565 (urethane acrylate resin from Synthese, Holland), 
     15 parts of 4,4&#39;-di-(β-acryloyloxyethoxy)-2,2-diphenylpropane (Ebecryl® 150, UCB, Belgium) and 
     23 parts of Irgalithblau® GLSM (Ciba-Geigy AG, Basle). 
     The mixture is homogenized on a 3-roll mill and ground down to a particle size of &lt;5 μm. 
     In each case 5 g of this printing ink are mixed homogeneously with the desired amount of photoinitiator on a plate grinding machine under a pressure of 180 kg/m 2 , while cooling with water. Samples with 3% and 6% of photoinitiator--based on the printing ink--are prepared. 
     Offset prints are made from these printing inks on 4×20 cm strips of art printing paper using a specimen printing apparatus (Pr ufbau, FR Germany). The printing conditions are: amount of printing ink applied: 1-5 g/m 2 , pressing pressure (line pressure): 25 kp/cm, printing speed: 1 m/second. 
     A printing roller with a metallic surface (aluminium) is used here. 
     The printed samples are cured in a UV irradiation apparatus from PPG using two lamps of 80 W/cm each. The irradiation time is varied by varying the rate of transportation of the sample. 
     The surface drying of the printing ink is tested by the so-called transfer test immediately after the irradiation. White paper is thereby pressed onto the printed sample under a line pressure of 25 kp/cm. If the paper remains colourless, the test has been passed. If visible amounts of colour are transferred to the test strips, this is an indication that the surface of the sample has not cured sufficiently. 
     The maximum rate of transportation at which the transfer test was still passed is shown in Table 5. 
     To test for complete curing of the printing ink, offset prints are likewise produced as described above, but printing rollers with a rubber surface are used and the metallic side of aluminum-coated strips of paper are printed. 
     The irradiation is carried out as described above. Complete curing is tested in a REL complete curing tester immediately after the irradiation. In this, an aluminium cylinder over which fabric is stretched is placed on the printed sample and rotated once around its own axis under a pressure of 220 g/cm 2  in the course of 10 seconds. If visible damage is thereby caused to the sample, the printing ink has not completely cured sufficiently. The maximum rate of transportation at which the REL test was still passed is given in the tables.

     EXAMPLE 6: Photocuring of a White Lacquer 
     A white lacquer is prepared in accordance with the following formulation: 
     17.6 g of Ebecryl® 593 (polyester acrylate resin from UCB, Belgium), 
     11.8 g of N-vinylpyrrolidone, 
     19.6 g of titanium dioxide RTC-2 (titanium dioxide from Tioxide, England), 
     19.6 g of Sachtolith® HDS (lithopone from Sachtleben Chemie, FRG), 
     11.8 g of trimethylolpropane trisacrylate and 
     19.6 g of Setalux® UV 2276 (acrylated epoxy resin based on bisphenol A, Kunstharzfabrik Synthese, Holland). 
     The above components are ground down to a particle size of not more than 5 μm together with 125 g of glass beads (diameter 4 mm) in a 250 ml glass bottle for at least 24 hours. 
     The stock paste thus obtained is divided into portions, each portion is mixed with in each case 2% of the photoinitiators shown in Table 6 by stirring at 60° C. and the mixtures are ground again with glass beads for 16 hours. 
     The white lacquers thus prepared are applied in a thickness of 70 μm to glass plates using a doctor blade. The samples are exposed on the one hand in a PPG irradiation apparatus with a 80 W/cm lamp and on the other hand in an irradiation apparatus from Fusion Systems (USA) using a D lamp, in each case in one passage. The rate of passage of the samples through the irradiation apparatus is thereby increased continuously until adequate curing no longer occurs. The maximum rate at which a lacquer film which is still wipe-proof forms is shown in Table 6 as &#34;curing rate&#34;.

     EXAMPLE 7: Sensitized Photocuring of a White Lacquer 
     The procedure is as in Example 6. However, in addition to the 2% of photoinitiator, 0.5% (based on the lacquer) of isopropylthioxanthone is also added as a sensitizer. A noticeable increase in the curing rate thereby occurs. The results are shown in Table 7.

     EXAMPLE 8: Photocuring of a Black Offset Printing Ink 
     A photocurable black offset printing ink is mixed with in each case 3% of the photoinitiators shown in Table 8 and paper laminated with aluminium foil is printed with the ink in an application amount of 1.5 g/m 2 , the procedure being as in Example 5. Curing is also carried out as described in Example 5 in the PPG apparatus with two lamps of 80 Watt. The curing is checked by the transfer test--as described in Example 5. Table 8 indicates the maximum rate of transportation in the irradiation apparatus at which the transfer test is still just passed.

     is dissolved in a mixture of 319 g methylene chloride and 30 g methanol. To this solution are added 0.5 g Irgalithgreen® GLN (Ciba-Geigy AG) and compound 10 as photoinitiator in the amounts indicated in table 9. 
     The viscous solution is applied to aluminium sheets in a thickness of 200 μm. After drying for 15 minutes at 60° the thickness is about 45 μm. The sample is covered with a polyester sheet (76 μm). An optical 21 step wedge (Stouffer wedge) is placed on the sheet and fixed by vacuum. The sample is irradiated for 20 seconds through the wedge with a 5 kW lamp at a distance of 30 cm. Afterwards the sheet is removed and the sample is developed in an ultrasonics bath. The developer employed is a solution of 15 g of Na 2  SiO 3 .9H 2  O, 0.16 g of KOH, 3 g of polyethylene glycol 6000 and 0.5 g of levulinic acid in 1000 g of water. After being briefly dried at room temperature, the samples are assessed. Table 9 indicates the highest step which is completely reproduced and has a non tacky surface. The higher the step, the more sensitive is the system.

     EXAMPLE 10: Preparation of a Printing Plate 
     88.6 parts of a butadiene/styrene copolymer (Cariflex® TR 1107, Shell Chemie) are plastisized on a calander at 140°. Then 11 parts of hexanediol diacrylate, 0.3 part of a phenolic antioxidant (Topanol® OC, ICI Comp.), 0.01 part of Sudan Black B and 0.4 part of compound 10 are admixed at 100° and the mixture is homogenized at this temperature. 
     Plates of 2 mm thickness are pressed from this mixture between two polyester sheets. The back of the plates is irradiated through the sheet in a BASF-Nyloprint irradiation device with 40 W lamps. The sheet on the face of the plate is replaced by a test negative and this side is exposed for 6 minutes through this negative. 
     The exposed sample is developed in a brushing bath with a mixture of 4 parts of tetrachloroethylene and 1 part of butanol, while washing out the soluble parts. After drying for 60 minutes at 80° the second sheet is removed and the printing plate is immersed successively in a 0.4 % aqueous bromine solution and a 1.5 % solution of Na 2  S 2  O 3  /Na 2  CO 3  followed by rinsing with water. 
     Finally, each side is irradiated for a further 6 minutes. All parts of the test negative are reproduced clearly. The depth of the indentations is 34 μm, the hight of the relief is 450 μm.
