The compounds of the formula (1 ) according to the present invention are particularly suitable as UV filters, i.e. for protecting ultraviolet-sensitive organic materials, in particular the skin and hair of humans and animals, from the harmful effects of UV radiation. These compounds are therefore suitable as sunscreens in cosmetic, pharmaceutical and veterinary medical preparations. These compounds can be used both in dissolved form and in the micronized state.

The UV absorbers according to the present invention can be used either in the dissolved state (soluble organic filters, solubelized organic filters) or in the micronised state (nano- scalar organic filters, particulate organic filters, UV-absorber pigments).

Any known process suitable for the preparation of microparticles can be used for the pre¬ paration of the micronised UV absorbers, for example wet-milling,wet-kneading, spray- drying from a suitable solvent, by the expansion according to the RESS process (Rapid Expansion of Supercritical Solutions) by reprecipitation from suitable solvents.

Presentation forms

The final formulations listed may exist in a wide variety of presentation forms, for example:

in the form of liquid preparations as a W/O, OfSN, OfSNIO, W/O/W or PIT emulsion and all kinds of microemulsions, in the form of a gel, in the form of an oil, a cream, milk or lotion, in the form of a powder, a lacquer, a tablet or make-up, in the form of a stick, in the form of a spray (spray with propellent gas or pump-action spray) or an aerosol, in the form of a foam, or in the form of a paste.

Of special importance as cosmetic preparations for the skin are light-protective preparations, such as sun milks, lotions, creams, oils, sunblocks or tropicals, pretanning preparations or after-sun preparations, also skin-tanning preparations, for example self-tanning creams. Of particular interest are sun protection creams, sun protection lotions, sun protection milk and sun protection preparations in the form of a spray.

Of special importance as cosmetic preparations for the hair are the above-mentioned prepa¬ rations for hair treatment, especially hair-washing preparations in the form of shampoos, hair conditioners, hair-care preparations, e.g. pretreatment preparations, hair tonics, styling creams, styling gels, pomades, hair rinses, treatment packs, intensive hair treatments, hair- straightening preparations, liquid hair-setting preparations, hair foams and hairsprays. Of special interest are hair-washing preparations in the form of shampoos.

A shampoo has, for example, the following composition: from 0.01 to 5 % by weight of a UV absorber according to the invention, 12.0 % by weight of sodium laureth-2-sulfate, 4.0 % by weight of cocamidopropyl betaine, 3.0 % by weight of sodium chloride, and water ad 100%.

Other typical ingredients in such formulations are preservatives, bactericides and bacterio¬ static agents, perfumes, dyes, pigments, thickening agents, moisturizing agents, humectants, fats, oils, waxes or other typical ingredients of cosmetic and personal care formulations such as alcohols, poly-alcohols, polymers, electrolytes, organic solvents, silicon derivatives, emollients, emulsifiers or emulsifying surfactants, surfactants, dispersing agents, antioxi¬ dants, anti-irritants and anti-inflammatory agents etc.

The cosmetic preparation according to the invention is distinguished by excellent protection of human skin against the damaging effect of sunlight. Preparation Examples

Example 1: Preparation of the compound of formula

A mixture of 8,58 g of dehydroacetic acid with 7,63 g of N.N-Dimethylformamid-dimethyl- acetate in 100 ml of tert.-butylmethylether is stirred for 8 hours at room temperature. Then the product is filtered off, washed with minor amounts of tert.-butylmethylether and dried in vacuum at 40⁰C. The yield is nearly quantitative. Fp: 159-161 ⁰C.

Example 2: Preparation of compound of formula

A mixture of 1 g of 1-Ethoxycarbonyl-1-cyano-2-(N-dimethylaminomethylen)amino-4-di- methylaminobutadiene (prepared according to Chem. Heterocycl. Compd. (Engl. Transl.), 24, 8, 1988, 918) with 0,43 g of p-toluidine in 10 ml of dimethylformamide is boiled for 1 hour. The solvent is evaporated, the residue is ground in ether, filtered and dried in vacuum at 40 "C yielding 0,75 g of colorless crystals. Fp: 210-216 ⁰C.

Example 3: Preparation of the compound of formula

A mixture of 8.62 g pyrrolidine, 16.34 g malonic acid-cycl.-isopropylidene ester and 14.68 g acetylacetaldehyd dimethylacetal in 100 ml Toluene are stirred for 45 minutes at room temperture an kept under reflux for 67 hours.

The reactio mixture is sitrred for 4 h at 3°C and finally for 16 h at room temperture. The raw product is filtered off and washed with diethylether and finally 4 times with 10 ml methanol.

After drying in vacuo at 60 ⁰C 2.70 g of the product of formula (1) are obtained as bright- orange crystals. λmax ⁼ 396 nm. Example 4: Preparation of the compound: of formula

A mixture of 1,16 g of 1-Ethoxycarbonyl-1-cyano-2-(N-dimethylaminomethylen)amino-4- dimethylaminobutadiene (prepared according to Chem. Heterocycl. Compd. (Engl. Transl.), 24, 8, 1988, 918) with 0,47 g of aniline in 11 ml of acetic acid is boiled for 1 hour. After cooling to room temperature the product is filtered off, recrystallized from toluene/ethyl acetate (1:1) yielding yellow crystals which were dried in vacuum at 40⁰C. The yield is 25 %. I_m3x = 363 nm.

Preparation of the emulsion

Phase (A):

Firstly, the UV absorber is dissolved in sesame oil. The other components of (A) are added thereto and combined.

Phase (B):

Propylparaben and methylparaben are dissolved in propylene glycol. 60 ml of water are then added, heating to 70⁰C is carried out and then carbomer 934 is emulsified therein.

Emulsion:

(A) is slowly added to (B) with vigorous application of mechanical energy. The volume is adjusted to 100 ml by the addition of water.
