Definitions
- the present invention relates to organic UV absorbers which are soluble in polar media, lacquer systems and coatings produced therefrom, which
- Absorber contain, and protected by such UV absorber-containing protective coatings finished parts.
- UV absorbers are biphenyl-substituted triazines (WO 2006/108520 A). This substance class shows an excellent absorption effect at 320-380 nm and at the same time a very high intrinsic UV stability (WO 2000/066675 A1, US Pat. No. 6,225,384). Because of their strong aromatic nature, the substances known to date in this class dissolve well only in non-polar and medium-polar media, which is sufficient for most UV-curable protective coatings based on purely organic base. It is known that such paint layers do not have sufficient scratch resistance. This restricts the applications of the outdoor systems, e.g. in the architectural field, and prevents some outdoor applications, e.g. as automobile glazing in the driver's field of view, all the way.
- Alkoxysilyl (alkyl) group modified UV absorbers for such resorcinol based paint systems have been disclosed in US-A 5,391,795 and US-A 5,679,820. The mono-modification described therein, however, can be transferred to biphenyl-substituted triazines neither in the synthesis path nor in effect.
- US-A-7,169,949 discloses triazine-based UV absorbers modified with a silane group. However, the mono-alkoxysilyl-substituted triazines described and shown there do not carry biphenyl substituents. The use of these triazines in organic coating compositions is described.
- organic-inorganic hybrid coatings in particular sol-gel coatings, are not mentioned.
- solubility of these mono-alkoxysilyl-substituted triazines in these paints is not given.
- the polar modified triazines shown here can not be prepared by the synthetic route presented in US Pat. No. 7,169,949.
- the UV-protective effect of the non-biphenyl-substituted triazines described therein is not optimal, especially for polycarbonate.
- Suitable polar-modified UV absorbers from the triazine substance class and their use in coating systems, such as hybrid paints, in particular sol-gel silicate paints, are therefore not yet known.
- the object of the present invention was therefore to provide U V absorbers of triazines which are substituted and modified such that they are soluble both in hybrid paints, in particular sol-gel paints, and have very good UV absorption quality.
- the object of the present invention was also the provision of polar coating systems which can be cured after application to a suitable substrate, such as a plastic, and show an effective and durable UV protection with high weather resistance.
- Coating compositions in the context of the present invention are defined as compositions comprising paints or coating materials which in combination form a common coating structure.
- Coating materials are all products of the paint and paint industry (see also: “paint from A to Z” Paolo Nanetto, Vinzentz, Hannover 2007.) Even if the term "paint” elsewhere often only on the outer, visible layer of In general, and also in the case of the present invention, the terms lacquer and coating materials are equated.
- the term "coating” is equated with one or more cured lacquer layer (s) or else dye and / or print layer (s) and / or further functional layers.
- Polar paints for the purposes of the present invention are paints whose coating materials are predominantly dissolved in polar solvents (mainly alcohols, such as, for example, methanol, ethanol, isopropanol, butanol).
- polar solvents mainly alcohols, such as, for example, methanol, ethanol, isopropanol, butanol.
- Sol-gel paints in the context of the present invention are paints which, according to the SoI
- the sol-gel process is a process for the synthesis of non-metallic inorganic or hybrid polymeric materials from colloidal dispersions, the so-called sols.
- Hybrid paints in the context of the present invention are based on the use of
- Hybrid polymers as binders.
- Hybrid polymers (hybrids: lat., "Of two origins") are polymeric materials that combine structural units of different classes of materials at the molecular level. The structure of these polymers allows hybrid polymers to exhibit completely novel combinations of properties, unlike composites (defined phase boundaries, weaker ones)
- Oligomer / polymer structures are produced.
- Surface-modified nanoparticle-containing acrylate coatings which form an organic / inorganic network after curing are also defined as a hybrid paint.
- Y 1 and Y 2 are independently substituents with the general
- X is a linear or branched linker, characterized in that between the O atom of group A and each T group is a chain of at least 4 atoms selected from carbon, oxygen, nitrogen, sulfur, phosphorus and / or silicon in the chain , For example, it may be an (optionally substituted)
- Hydrocarbon chain - (CR 2 ) - j where j is an integer greater than 3, or it may be interrupted by O, N, S, P and / or Si, optionally single or multiple, even different, substituted hydrocarbon chain
- the Rs independently of one another, preferably stand for H or alkyl radicals.
- P is a mono-, di- or trialkoxysilane group, alkoxy preferably being methoxy, ethoxy or (2-methoxy) ethoxy, and n is an integer between 1 and 5.
- alkoxy preferably being methoxy, ethoxy or (2-methoxy) ethoxy
- n is an integer between 1 and 5.

- the new silylated triazine-based UV absorbers can be incorporated into thermally curable sol-gel coating systems to provide scratch-resistant coatings with high UV protection.
- Sol-gel coating systems have no special requirements, they can be adjusted to acidic, basic or neutral. For example, such sol-gel coating solutions by

- the colloidal silica particles can also be formed in situ by precondensation starting from alkoxysilanes (see “The Chemistry of Silica”, Ralph K. Her, John Wiley & Sons, (1979), pp. 312-461).
- the hydrolysis of the sol-gel solution is carried out by adding solvents, preferably alcoholic solvents, e.g. Isopropanol, n-butanol, isobutanol or mixtures thereof, stopped or greatly slowed down. Subsequently, one or more UV absorbers of the invention, optionally in a
- Solvent are pre-dissolved, added to the sol-gel coating solution, after which an aging step of a few hours or several days / weeks occurs. Furthermore, it is also possible to add further additives and / or stabilizers, such as leveling agents, surface additives, thickeners, pigments, dyes, curing catalysts, IR absorbers, UV absorbers and / or adhesion promoters.

They can therefore be used wherever a UV-labile substrate is to be protected from UV radiation, primarily from sunlight or from an artificial radiation source. Many plastics, but also natural products such as wood, can be permanently protected from photochemical degradation by the coatings according to the invention.
