Description

USE OF DERIVATIVES OF 4-CYANO-NAFTALEN-1, 8-DICARBOXAMIDE AND RELATED COMPOUNDS TO PROTECT ORGANIC MATERIAL A STARTING FROM HARMFUL EFFECTS OF LIGHT DESCRIPTION OF THE INVENTION The present invention relates to the use of naphthalene-1, 8-dicarboxylic monoimides to protect organic material against the damaging effects of light, to compositions which comprise at least one organic material and at least one monoimide naphthalene-1 , 8-dicarboxylic of the formula I in an amount that provides protection from the damaging effects of light, and new monoimides naphthalene-1, 8-dicarboxylic. Living and inanimate organic material such as human or animal skin, human or animal hair, paper, food, perfumes, cosmetics, plastics, polymer dispersions, paints, photographic emulsions, photographic layers, etc., is often sensitive to the damaging effects of light, and particularly to the fraction of ultraviolet (UV) radiation which occurs in daylight. The damage may be due to the UVA fraction of the UV radiation, that is, the region of approximately 320 to 400 nm, the UVB fraction of the UV radiation, ie the region from 280 to 320 nm, and the fractions even shorter wavelength of UV radiation. There is therefore a substantial and constant demand for new substances which provide effective protection against such harmful effects. In this application, the substances employed have to comply increasingly with a complex profile of requirements designed for the specific nature of the organic material that is protected, the circumstances under which protection is required and the desired protective effect. It is known that the mechanical, chemical and / or aesthetic properties of organic material, particularly plastics, can deteriorate under the effect of light. This deterioration usually manifests as yellowing, discoloration, cracking or cracking in the material. An important field of use for light stabilizers is therefore the protection of plastics. Plastic containers and plastic films find widespread use as packaging materials, for example. For aesthetic reasons, plastics that exhibit light intensity transmission in the visible wavelength range from 400 to 750 nm are increasingly gaining importance as packaging materials. Clear plastics with or without light coloration, however, are generally transparent to the UV fractions of daylight, with the consequence that, under light, both the packaging material and the packaged products suffer from aging.

Depending on the specific packaged contents, the adverse alteration to the contents may be manifested, for example, in a change of appearance, such as yellowing and discoloration, in a change in taste and / or odor, and / or in the decomposition of ingredients . In the case of food, perfumes and cosmetics, shelf life and preservation properties can be abruptly reduced. The stabilizers that are added to the plastic for packaging must therefore provide satisfactory protection both in the plastic itself and in the packaged product with respect to aging processes induced by light. Plastics are also in widespread use in combination with glass in composite materials which are transparent in the visible wavelength range. Composite systems of this kind find use in automotive or architectural varnishing, for example. The windows of cars of this class increasingly require absorbing radiation in the wavelength range below 400 nm, in order to protect the interior of the car and its occupants from UV radiation, for example. GB 1,003,083 describes 4-alkoxynaphthalene-1, 8-dicarboxylic monoimides and their use as optical brighteners for fabrics. The fabrics may consist of natural or synthetic fibers, including polyamides, polyesters, polyurethanes, polyvinyl chloride, polyvinylidene chloride, polyacrylonitrile or polyvinyl alcohols. EP 0682145 describes a method for improving the sun protection factor in fabrics, wherein the woven fiber is treated with a composition comprising at least one optical brightener which is absorbed in the wavelength range of 280-400 nm. In addition to a host of the additional compounds, the suitable optical brighteners specified include (by way of a formula) naphthalene-1, 8-dicarboxylic monoimides which carry in the 4 or 5 position a C 4 -C 4 alkoxy , S03M (wherein the definitions of M include H, Na, K, Ca, Mg, ammonium or mono-, di-, tri- or tetra-alkylammonium of C? -C) or an NHCO-C-alkyl group? C4 The only specific substituted 4 compound described is the 4-methoxy compound. There are no usable examples for this class of compound. EP 0263705 discloses the use of naphthaletracarboxylic acid or its derivatives as light stabilizers in thermoplastic polyester resin compositions, wherein additional components that may be used include naphthalene monoimides. The imide group of the monoimides may be in positions 1,8, 2,3 or 3,4 of the naphthalene ring. Additionally, the naphthalene ring is not substituted or can transport up to 6 additional substituents, selected from halo, hydroxyl, amino, nitro, cyano, sulfonic acid or metal salts thereof, optionally substituted alkyl, optionally substituted alkenyl, optionally aralkyl substituted and optionally substituted alkylaryl. Preferably, the naphthalene ring of naphthalen monoimides does not carry any of the additional substituents. EP 0335595 discloses thermoplastic polyester compositions comprising as UV absorbers a diimide compound, more so if desired, a naphthalene monoimide. The imide group of the monoimide can be located in positions 1,2, 1,8 or 2,3 of the naphthalene ring. The naphthalene ring can carry up to 6 additional substituents, selected from halo, carboxyl or an ester thereof, hydroxyl, -0-C (= 0)) CH3, amino, nitro, cyano, sulfonic acid or a metal salt thereof , optionally substituted alkoxy, optionally substituted aliphatic groups and optionally substituted aromatic groups. JP1024852 describes the use of substituted or unsubstituted naphthalenedicarboxylic and tetracarboxylic acids or their esters, imides and anhydrides as light stabilizers for polyamide resins. The polyamide resins can be used as packaging material for food. JP-7247978 describes rinsing compositions for synthetic fibers, comprising a mixture of 4-substituted naphthalene-1, 8-dicarboxylic monoimides and, if desired, alkylnaphthalenesulfonates. The mixture comprises naphthalenecarboxylic monoimides wherein the substituent at the 4-position is an unsubstituted lower alkoxy or phenoxy or a benzyloxy group and compounds wherein the substituent at the 4-position is an alkylthio, phenylthio or benzylthio group. The imide nitrogen atom can in each case be replaced by a hydrogen atom or by an alkyl or hydroxyl group. A significant disadvantage of the naphthalene-1, 8-dicarboxylic monoimides substituted and unsubstituted with phenoxy and / or substituted with lower alkoxy described is their low compatibility with plastics. The light stabilizers of the prior art have a number of disadvantages. A substantial disadvantage is the period of the protective effect, which is often too short, since the known light stabilizers often have inadequate UV stability. Another disadvantage is that many known light stabilizers have an intrinsic color clearly discernible in the visible wavelength range, with the consequence that a plastic stabilized with these light stabilizers appears to have a pale yellow coloration. further, many light stabilizers are unable to filter the long wave fraction of UVA radiation. Many light stabilizers exhibit low solubility in the application medium. The resulting crystallization of the light stabilizer may render the polymer opaque. Additional advantages are the often deficient synthetic availability of light stabilizers, their inadequate formulation properties, their low resistance to sublimation and / or their low migration strength. There is therefore still a need for stabilizers and stabilizer compositions which have improved performance properties and / or are easier to prepare. It is an object of the present invention, therefore, to provide stabilizers which are suitable as UV absorbers for protecting organic material such as plastics, polymer dispersions, paints, photographic emulsions, photographic layers, paper, human or animal skin, human hair or animal, food, etc., for a relatively long period of time. The stabilizers should preferably be absorbed with high extinction in the UVA region, and particularly also in the long wave UVA region above 360 nm, they should be photostable and / or thermally stable, and they should have little or no intrinsic color in the range of visible wavelength. Surprisingly, it has now been found that the use of naphthalene-1, 8-dicarboxylic monoimides of the formula I wherein R1 is hydrogen, alkyl, alkenyl, cycloalkyl, cycloalkenyl, heterocycloalkyl, aryl or heteroaryl and R2 is a radical containing at least one electron system p containing a carbon atom and at least one further atom selected from carbon, oxygen and nitrogen, with the proviso that the radical contains at least one atom other than carbon to protect the organic material against the damaging effects of light. The present invention consequently provides the use of naphthalene-1, 8-dicarboxylic monoimides of the formula I to protect organic material against the damaging effects of light. The present invention further provides a composition comprising at least one organic material and at least one naphthalene-1, 8-dicarboxylic monoimide of the formula I in an amount that provides protection against the detrimental effects of light.

The present invention further provides a method for protecting the organic material against the deleterious effects of light, which involves adding to the material at least one naphthalene-1, 8-dicarboxylic monoimide of the formula I.

In order to remove the copper salts, particularly the copper (I) salts, it can be advantageous to convert the salts within the copper (II) salts by oxidation in aqueous solution, with acid peroxide or salts of the product, from the product. Iron (III), for example, and then isolate the product by extraction with a water-immiscible, organic solvent. In addition, the copper salts can be removed by treatment with aqueous solutions of compound reagents, such as ammonia, monoamines or organic diamines, and soluble cyanide salts. An alternative option is to extract the product with organic solvents, for example, chlorinated hydrocarbons such as dichloromethane or 1,2-dichloroethane or ketones such as acetone, with the aid, for example, of a Soxhlet apparatus, from the unpurified product. The 4-halonaphthalen-1,8-dicarboximides II can be prepared, for example, by reacting anhydrides III 4-halonaphthalen-1,8-dicarboxylic acids with a primary IV amine according to the reaction sequence described in scheme 2.

In general, the reaction takes place at a temperature between room temperature and the boiling temperature of the solvent, preferably at elevated temperature, and in particular at the boiling temperature of the solvent. It is normal to use compound III and amine IV in approximately equimolar amounts. It can, however, be advantageous to use one of the two reagents in excess. It may be advantageous to remove the water formed during the reaction from the reaction mixture, using a water separator, for example. The reaction mixture is developed by cooling it, diluting it with water when appropriate, and isolating the product by filtration. The product can, if desired, be purified in a customary manner, by crystallization or chromatography, for example. The anhydrides III 4-halonaphthalen-1, 8-dicarboxylic anhydrides are known from the literature or can be prepared by known methods.

GmbH, Hamburg) and the concentration of compound I set forth in Table 3 in a Berstorff twin-screw extruder (melting temperature: 275 ° C) and then granulated. The resulting granules were subsequently extruded in a Weber single screw extruder through a fluted die (melting temperature: 225 ° C) and pressed to a thickness of 300 μm through a roller graft. The results are summarized in Table 3. The parameters reported are the wavelengths below which less than 10% or 20% of the radiation passes through the film. A value below and preferably close to 400 nm means that the material under the film is effectively protected against UV radiation.

Table 3: maximum wavelength with a transmission of less than 10% maximum wavelength with a transmission of less than 20%. The examples show that the naphthalene-1, 8-dicarboxylic monoimide I used according to the invention can be effectively incorporated into PET films. The monoamino I naph alen-1, 8-dicarboxylic monoimides used according to the invention filter out most of the harmful UV radiation from the spectrum and are therefore suitable as effective UV filters.

Example 22: Exposure of an addition PET film The PET film was exposed from Example 17 (containing 0.4% of compound IA.l) for 1000 hours in accordance with DIN 54004. The transmission profile of the film was measured at regular intervals and is shown in Table 4.

Examples 22 and 23 show that naphthalene-1, 8-dicarboxylic monoimides I are photostable, ie they do not spoil. Accordingly, the naphthalene-1, 8-dicarboxylic monoimides I are suitable long-term UV filtering substances. Examples 24 to 30: Production of PET moldings (thickness: 1 mm) As described in Examples 17 to 20, in Examples 24 to 28, PET granules and the concentration of compound I indicated in Table 6, and in Examples 29 and 30 (comparative), PET pellets were produced and the concentration indicated in Table 6 of a commercially conventional UV absorber (2- (2H-benzotriazol-2-yl) -4,6-bis ( 1-methyl-1-phenylethyl) phenol (CAS number 70321-86-7), commercially available for example under the name Tinuvin® 234 from Ciba Specialty Chemicals). Subsequently, injection moldings with a thickness of 1 mm were produced in an Arburg 220M injection molding machine. In Example 24 (control) the PET molding does not contain a UV absorber. In Example 28, PET molding contains an additional 0.1% by weight of an additional UV absorber, i.e. 1,3-bis [(2'-cyano-3 ', 3'-diphenylacryloyl) oxy] -2 , 2-bis. { [2'-cyano-3 '3' -diphenylacryloyl) oxy] methyl} propane [CAS No. 178671-58-4], commercially available for example under the name Uvinul® 3030 from BASF AG, Ludwigshafen. The yellowing indices (Yl, according to DIN 6167) of the injection moldings of Examples 24 to 30 are reported in Table 6. A zeroing index of zero means that the specimen is pure white. Negative YI values mean that the specimen is bluish (the more negative Yl, the more blue). Positive Yl values indicate that the specimen is yellowish. The more positive Yl, the more yellow the specimen looks to the viewer. The addition of a UV absorber to a plastic generally implies an increase in Yl.

Example 31: Protection of Vitamin A An ethanolic solution of vitamin A (c = 10-5 moles / 1) in a tube was exposed to a xenon lamp. The PET plates of Examples 24-26 were placed in the beam path of the xenon lamp. During irradiation, the remaining concentration of vitamin A was measured from its absorbance at 323 nm. Figure 1 shows the effect of the filter of the compounds I used according to the invention, as a graph. Since the emission spectrum of a xenon lamp is similar to that of the sun, Figure 1 strongly demonstrates the filter effect of the naphthalen-1, 8-dicarboxylic monoimides I used in accordance with the invention. Without the protection of the naphthalene-1, 8-dicarboxylic monoimides a solution of vitamin A rapidly disintegrates by light. In contrast, there is only slight disintegration of the vitamin A solution under the effect of light if the vitamin A solution is protected by a naphthalene-1, 8-dicarboxylic monoimide used in accordance with the invention.
