Description

Technical Field

[0001] The invention claimed herein relates to ultraviolet (UV) absorbing compounds and methods for their preparation. Background Technology

[0002] Ultraviolet (UV) light absorbers are an important class of organic compounds used to protect and stabilize organic materials such as plastics, polymers, and coatings from damage caused by light, heat, oxygen, or environmental forces. These stabilizers are also widely used in personal care products, fibers, paints, dyes, and more.

[0003] These stabilizers protect materials by converting absorbed ultraviolet light into low-impact heat and energy. Stabilizers are primarily used to reduce photodegradation (e.g., in plastics or polymers) by playing a key role in suppressing the generation of free radicals that lead to plastic degradation. While both UVA and UVB are known to induce material degradation, UVA is considered to contribute more to this degradation due to its greater abundance in sunlight. In this regard, two commonly used classes of UV stabilizers that provide significant protection against both UVA and UVB are substituted benzotriazoles (BTZ) and substituted triazines, such as hydroxyphenyltriazine (HPT).

[0004] There is a wealth of literature on the use of such triazine and benzotriazole-based stabilizers for UV stabilization. For example, WO 2019006750A1 describes the use of reactive benzotriazole based on mono-trimethylolpropane, primarily for stabilizing polyurethanes against UV degradation. More recently, US2017 / 0349730 A1 introduces compositions comprising hydroxyphenyltriazine and hindered amine stabilizers combined with antioxidants and phosphites into molded articles to achieve suitable thermal and UV stability.

[0005] However, several challenges have been identified in this field. For example, the low molecular weight of well-known stabilizers makes them highly incompatible with their use in plastics, leading to a high level of migration of these molecules toward the material boundaries, resulting in poor long-term stability of the material. This is offset in WO 2010130752 A1 by synthesizing a stabilizer moiety with multiple benzotriazole sections. It has also been noted that the compound exhibits improved integration within the polymer matrix, leading to improved stability.

[0006] However, despite the improvements mentioned above, other challenges remain related to this field. For example, typical stabilizer compounds may have poor solubility in common organic solvents such as xylene. This lack of sufficient solubility makes the compounds economically and environmentally unsuitable for industrial applications. Furthermore, the environmental impact associated with compound synthesis is a significant concern in today's world, amidst growing environmental problems. Therefore, there is a high demand for stabilizers that impose a limited burden on the environment.

[0007] Therefore, there is an unmet need for developing UV stabilizer compounds that are environmentally friendly while maintaining important performance parameters such as high solubility, processability, and stability. Summary of the Invention

[0008] Surprisingly, it was found that incorporating UV absorbers into polyether polyols obtained through the reaction of at least one sugar and polyol with epoxides and optionally fatty acids not only improves their long-term stability but also enhances their solubility in organic solvents such as xylene. Furthermore, the incorporation of bio-associated sugars mitigates the environmental impact of UV absorbers.

[0009] Therefore, the first aspect of the invention claimed herein relates to a product or a salt thereof, which is obtainable by a method comprising the following steps:

Preferred monosaccharides are 5-carbon (pentose) or 6-carbon (hexose) sugars. It is well known that such monosaccharides can be chemically bonded to each other via glycosidic bonds to produce short-chain or long-chain (disaccharide, oligosaccharide, or polysaccharide). Both monosaccharides and bonded chains of sugars (disaccharides, oligosaccharides, or polysaccharides) are considered relevant to this invention. Suitable polysaccharides can be as defined in WO 2006040335 A1 and WO 2006040333A1.

[0110] Further classification of sugars can be based on the availability of free aldose or ketose groups that allow participation in reduction reactions. Reducing sugars such as glucose and non-reducing sugars such as sucrose are considered part of the invention claimed herein.

[0111] In the context of this invention, sugar is selected from C5-C6 sugar alcohols, monosaccharides, oligosaccharides, polysaccharides, or mixtures thereof. C5-C6 sugar alcohols have at least 5 hydroxyl groups, preferably 5-6 hydroxyl groups.

Ethylene oxide, propylene oxide, 1,2-epoxybutane, 2,3-epoxybutane, isobutane, and pentane are more preferred, and propylene oxide and ethylene oxide are even more preferred.

[0115] Suitable polyether polyols can be prepared by methods described in the presence of fatty acids, fatty acid monoesters, or mixtures thereof. In the context of this invention, the term "fatty acids, fatty acid monoesters, or mixtures thereof" describes fatty acid glycerides, particularly fatty acid triglycerides, and / or fatty acid esters based on other monofunctional and polyfunctional alcohols. Suitable fatty acids or monoesters can be those listed in US 9284401B2 and US2014 / 0200327 A1. The fatty acid groups of the fatty acid esters can further carry hydroxyl groups, as in the case of castor oil. Of course, according to the invention, fatty acid esters whose fatty acid groups are subsequently modified with hydroxyl groups can also be used. Fatty acid groups modified in this way can be obtained, for example, by epoxidation of the olefinic double bond, followed by ring-opening of the ethylene oxide ring by means of a nucleophile or by hydroformylation / hydrogenation. For this purpose, unsaturated oils are also frequently treated with atmospheric oxygen at high temperatures.

Specific examples may be cottonseed oil, peanut oil, coconut oil, flaxseed oil, palm kernel oil, olive oil, corn oil, palm oil, castor oil, lesquerella oil, rapeseed oil, soybean oil, sunflower oil, herring oil, sardine oil, tallow, and lard. Of course, according to the invention, other fatty acid esters of monofunctional or polyfunctional alcohols and fatty acid glycerides having fewer than three fatty acid groups per glycerol molecule may also be used. Fatty acid triglycerides and other fatty acid esters of monofunctional and polyfunctional alcohols may also be used in mixtures.

[0254] Application testing:

[0255] The products of this invention can be used as UV stabilizers and have been tested in thermosetting acrylic clear coatings having the following compositions (as described in Examples 1-4 above):

[0256]

[0257] 1) Acrylic resin (60% solution in xylene / butanol 26:9); Allnex

[0258] 2) Acrylic resin (in Solvesso 150) 4) (75% solution); Zhanxin Company

[0259] 3) Melamine resin (55% solution in isobutanol); Ineosmelamines

[0261] 5) 1% of Solvesso 150 4) Borchers (China)

[0262] The solids content of the composition is 53%.

[0263] The products of the present invention to be tested (UV stabilizers) (Examples 1-4 described above) were added to the clear coating in the amounts shown in Table 5 based on the coating solids content. Different dosage levels were required due to the varying UV-absorbing chromophore content in the test compounds, and adjustments were necessary to evaluate the stabilizing effect. The coating formulation was additionally mixed with 1% by weight of a co-stabilizer (compound z) (Tinuvin 123) having the following formula, based on the coating solids content.

[0264]

[0265] A transparent coating is applied to a white roll-coated panel to produce a dry film thickness of approximately 40 μm after curing (at 130°C for 30 minutes).

[0266] The coated panels were subjected to artificial aging cycles in an Xe-WOM aging apparatus from Atlas Corp., according to SAE-J2527. After a certain exposure time, gloss was measured at 20°C, and then exposure was continued. The retained gloss is an indicator of the UV stabilizing effect of the tested UV absorber in the coating film; lower gloss indicates more surface degradation.

[0268]

[0269] *Not measured due to intense crack formation; #Amount relative to solids content in wt.-%

[0270] Blank samples (without any stabilizer) revealed severe degradation of the coating film due to insufficient stability. The UV stability characteristics, indicated by the gloss of the product of the claimed invention, are compared with standards. 1130 or 384-2 is comparable.
