The present invention relates to a composition based on a latent curing catalyst acid-curable resin, containing this latent curing catalyst, and to a method for curing this resin by irradiation with short wave light and subsequent heating. Acid-curing resins are used as binders in varnishes, printing inks and coatings, especially when high temperature baking is to be avoided. Such acid-curable resins include amino resins such as etherified, esterified or otherwise modified melamine resins, urea/formaldehyde resins,
Examples include phenol/formaldehyde resins and mixtures thereof with alkyd resins, polyester resins or acrylic resins. Furthermore, acid-curing resins include resins containing methylol compounds, methylol ethers of polycarboxylic acid imides, derivatives of polyacrylic acid or polymethacrylic acid, urethane alkyds and carboxylic esters of N-methylolimide.
Acid curing catalysts include primarily organic acids, such as sulfonic acids, especially p-toluenesulfonic acid. However, since these acids exhibit a gradual curing effect even at room temperature, they must be added to the resin immediately before use, which poses the problem that a certain working time must be strictly observed. The use of latent curing catalysts, in which the acid is liberated at elevated temperatures, has already been proposed to make one component systems possible. Examples of such catalysts are amine salts of aromatic sulfonic acids,
For example, pyridine salts as proposed in US Pat. No. 3,474,054. However, such salts have the disadvantage of slowly curing during storage, and in addition, there is the problem of odor. Furthermore, it has been proposed to use latent curing catalysts in which the actual curing catalyst is formed by ultraviolet irradiation. Examples of these are aromatic sulfonium salts of complex anions as described in US Pat. No. 4,102,687. However, this type of sulfonium salt is difficult to produce, difficult to obtain as a pure product, has low reactivity, and tends to cause yellowing of the resin. Photochemically changing sulfonic acid esters, such as those described in DE 1919678,
Sulfonic acid esters of α-hydroxymethylbenzoin have already been proposed which act according to the above principle. However, these compounds have, for example, excellent storage stability, complete solubility in acid-cured resin compositions, resistance to yellowing of the resin after curing, and no negative effect on varnishes after electrophoretic painting. does not satisfy all of the requests. The present inventors have discovered that certain types of sulfonic acid esters of β-hydroxycarbonyl compounds, which can be easily produced industrially, can be stored in the dark for an unlimited period of time, but when irradiated with short wavelength light, they decompose rapidly and It has been found that the above-mentioned requirements can be satisfied in that the resin can be cured by an acid catalyst at a low temperature and does not have a tendency to yellow. The present invention uses the acid-curing resin and the latent curing catalyst as follows: (In the formula, n represents the number 1 or 2, R 1 is an unsubstituted phenyl group or naphthyl group,

Among the intermediates represented by the formulas, , , , or, the interfering ones are known compounds, while the other intermediates represented by the formulas are new. The invention therefore also relates to these compounds. These can be produced according to known compounds. A sufficient amount of a curing catalyst of the formula is added to the resin for curing. The amount required depends not only on the type of resin but also on the intended curing temperature and curing time. It is generally used in an amount of 0.1 to 10% by weight, preferably 0.5 to 5% by weight, based on the solvent-free resin. Mixtures of curing catalysts of the formula can also be used. Regarding acid-curing resins, all resins whose curing can be accelerated by acid catalysts can be used. These include in particular varnishes based on acrylic resins, polyester resins, alkyd resins, melamine resins, urea resins and phenolic resins, in particular mixtures of acrylic resins, polyester resins or alkyd resins with each other or with melamine resins. is suitable for use. Also modified varnish rubber,

It is described on pages 613-628. Acid catalysts are particularly important for the curing of varnishes containing etherified amino resins, such as methylated or butylated melamine resins (N-methoxymethyl or N -butoxymethyl-melamine or methylated/butylated glycolurils and similar), e.g. The following can be mentioned. Other resin compositions include polyfunctional alcohols, or acrylic or polyester resins containing hydroxyl groups, or partially hydrolyzed polyvinyl acetate or polyvinyl alcohol and polyfunctional dihydropyranyl ethers, such as 3,4-dihydro-
It is a mixture with 2H-pyran-2-carboxylic acid. For certain purposes, resin compositions containing monomeric or oligomeric components having polymerizable unsaturated groups can also be used. Resin compositions of this type can also be cured according to the method of the invention. In this case, free radical polymerization initiators or photopolymerization initiators, such as aromatic ketones, benzoyl compounds, benzyl ketals or derivatives of α-hydroxyacetophenones or compounds of the formula, may additionally be used. Can be done. The former initiates polymerization of unsaturated groups during heat treatment, and the latter initiates polymerization upon UV irradiation.
Resin compositions of this type containing unsaturated components can also be polymerized by electron beam. However, the polymerization of the unsaturated components must necessarily be accompanied by acid-catalyzed Chinese formation (by baking, if necessary). The varnish may be in the form of a solution or dispersion of varnish gum in an organic vehicle or water, or may be solvent-free. Varnishes containing small amounts of solvent are of particular interest, so-called "high solids varnishes." The varnish may be a lightening varnish, such as is used, for example, as a topcoat in multilayer coating paints in the automotive industry. The varnishes can be formulated with inorganic or organic pigments and can also contain metal powders for varnishes with a metallic effect. Furthermore, the varnishes can also be loaded with relatively small amounts of special additives commonly used in the varnishing industry, such as flow control agents, thixotropic agents, light stabilizers or antioxidants or photoinitiators. and so on. Examples of light stabilizers include hydroxyphenyl-
Examples include benzotriazoles, hydroxybenzophenones, cyanoacrylates, hydroxyphenyl-triazines, oxalanilides, organic nickel compounds, and polyalkylpiperidine derivatives. Note that UV-absorbing light stabilizers may inhibit the UV irradiation of the present invention, so in such cases, this type of light stabilizer can be added to the adjacent varnish layer. The light stabilizer can be gradually dispersed into the stoving varnish layer to be protected from within the adjacent varnish layer. This adjacent varnish layer may be a brimer varnish below the stoving varnish or a top coat varnish on top of the stoving varnish. As a further method of avoiding the inhibitory effect of UV absorbers, it is also possible to use so-called "latent UV absorbers", such as those described in DE 26 48 367 A1. Fries: Substances capable of producing ultraviolet absorbers through photorearrangement reactions;
For example resorcinol monobenzoate may also be applied. Also preferred is a polymethylpiperidine derivative or a combination thereof with a (latent) ultraviolet absorber. Particularly preferred specific examples of the composition of the present invention are described below. (a) A composition containing an amino resin or a mixture of an amino resin and another acid-curable resin as the acid-curable resin. (b) A composition containing a phenolic resin or a mixture of these resins and other acid-curable resins as the acid-curable resin. (c) containing as resin a mixture of at least one polymerizable compound having one or more polymerizable ethylenically unsaturated bonds and at least one aminoplast such as a melamine or urea/aldehyde resin; , also containing a free radical polymerization initiator and, if appropriate, a photoinitiator. Examples of polymerizable compounds having one or more ethylenically unsaturated bonds are acrylates and methacrylates and hydroxyethyl acrylates and methacrylates of glycols and polyols, diacrylates and polyacrylates and dimethacrylates and polymethacrylates, aromatic vinyl and divinyl derivatives, N-methylol derivatives of acrylamide or methacrylamide, vinyl alkyl ethers, trimethylolpropane, diallyl ether mono(meth)-acrylates, reaction products of glycidyl (meth)acrylate with mono- or dicarboxylic acids, These are polyester resins of saturated dicarboxylic acids or their anhydrides and diols, urethane acrylates, and polyepoxy polyacrylates. Preferred compositions include (A) 80 to 99% by weight of a polymerizable compound having one or more ethylenically unsaturated bonds; (B) 1 to 20% by weight of a melamine or urea/formaldehyde resin. At least one aminoplast (C) contains from 0.1 to 10% by weight of a curing catalyst of the formula based on the sum of A and B. The invention further relates to a method for curing acid-curable resins by irradiation with short wavelength light and subsequent heating in the presence of a curing catalyst of the general formula. Irradiation of the resin with short wavelength light is preferably carried out with ultraviolet light, and a wide variety of industrial equipment is available today for this purpose. Such objects include medium pressure, with a maximum irradiation wavelength of 200 to 400 nm;
Includes high or low pressure mercury lamps and fluorescent tubes. The irradiation time varies depending on the thickness of the resin layer, the pigment, the luminous intensity of the lamp, and the irradiation distance. If the varnish does not contain pigments and has a normal thickness, it can be applied in a few seconds in a conventional ultraviolet irradiation device. During this irradiation, the latent catalyst is photochemically converted to free sulfonic acid.
Irradiation can also be carried out with a daylight lamp if a photosensitizer is added to the resin. Known photosensitizers include fused aromatics such as perylene, aromatic amines (e.g. U.S. Pat. No. 4,069,054
and cationic dyes and basic dyes (such as those described in US Pat. No. 4,026,705). Since acid curing proceeds very slowly at room temperature, heat treatment is required following irradiation industrially. However, compared to other methods using curing catalysts that are split by heating, this heat treatment can be performed at relatively low temperatures. about 30
A stoving temperature of 70 to 80° C. is sufficient when using a stoving time of 50 minutes and about 2% catalyst. When using 1% catalyst, a temperature of about 80 to 100°C is required, and when using a catalyst amount of 0.5%, the temperature is about
Must be between 100 and 120°C. Preferably, the catalyzed resin in the present invention is cured by baking at 130°C or less after irradiation.
On the other hand, when curing using a known sulfonic acid amine salt (without irradiation), the baking temperature is 130°C.
It needs to be above â. The relatively low baking temperature in the method of the invention
Temperature sensitive substrates such as wood products, cardboard products,
It is of great importance in particular for the painting or varnishing of products containing plastic or rubber parts, such as electrical appliances, vehicles or machines of all types. Other one-component systems (one-
A further advantage of the component compositions of the present invention compared to component system resins is that they are not subject to any limitations on shelf life at room temperature. This is because an active catalyst is only formed by irradiation. The method of the invention is suitable for all types of industrial painting and varnishing, for example for varnishing machines, vehicles, ships or structural elements. Of particular interest is automotive varnishing, in which case it can be used for single-layer varnishing or for multi-layer varnishing. It is also of particular interest to apply the method of the invention for the continuous coating of metal plates, for example steel plates or aluminum plates, in the so-called coil coating method. In addition, the method of the invention can be applied to the curing of acid-curable printing inks, which are particularly suitable for printing on tinplate boards due to their excellent compatibility. When applying the method of the invention to compression molding materials, casting resins and laminating resins, these resins are first irradiated in a thin layer, followed by thermoforming and curing to obtain the desired article. be able to. However, if these articles have a relatively small thickness, the resin may be shaped first, followed by irradiation and heating. When the resin is irradiated, the thickness of the resin layer may be several millimeters, depending on its transparency. This method can also be used for relief imaging, for example for the production of printing plates. In this case, a solid or liquid acid-curable resin composition (which composition may also contain unsaturated monomers or prepolymers) is first exposed through a negative film. Subsequently, post-treatment by heating is performed to crosslink the exposed portions. Finally, development is carried out by washing away the non-crosslinked portions of the printing plate. The method of the present invention will be explained in more detail using specific compositions in Examples below. In the examples, "parts" and "%" are expressed by weight, and pressure is expressed in "bar" or "millibar". Production Example Example 1 Equipped with a stirrer, thermometer and nitrogen gas passage
126 parts (0.75 moles) of α-chloropropiophenone and 24 parts (0.8
mol) and then 95 parts (0.85 mol) of solid potassium tert-butyrate are added in small portions over 1 hour each time. During the addition, the temperature rises to about 40° C. and a reddish-brown suspension forms, which is stirred for a further 5 hours. The reaction mixture is then poured into 1 liter of ice/water and the resulting solution is extracted with two 750 ml portions of diethyl ether. Combine organic phase

This corresponds to a yield of 70% of theory, based on the α-chloropropiophenone used. 81 parts (0.5 mol) of the above epoxy compound and p-toluenesulfonic anhydride (by azeotropic dehydration from the corresponding monohydrate according to Hauben-Weell, Methods of Organic Chemistry, Vol. 9, p. 436) Add 86 parts (0.5 mole) to 500 ml of toluene in a 1 liter round bottom flask, stir at 60°C for 16 hours while excluding water, and confirm the end of the reaction by thin-phase chromatography. . Pour the reaction solution into 1 liter of ice-cooled aqueous sodium bicarbonate solution.
After separating the aqueous phase, the organic phase is dried with Na 2 SO 4 and kept at a bath temperature of 40°C or 40°C while suctioning with an aspirator.
