[0002] AZIRIDINYL-FUNCTIONAL ORGANIC COMPOUNDS

[0003] FIELD OF THE INVENTION

[0004] The invention lies in the field of aziridinyl-functional organic compounds.

[0005] BACKGROUND

[0006] There is an increasing demand for coatings having enhanced ethanol resistance (abbreviated in the specification as ‘ER’), preferably combined with one or more of coating properties such as enhanced red wine resistance (abbreviated in the specification as ‘RWR’), and water resistance (abbreviated in the specification as ‘WR’).

[0007] Enhanced ER is desirable because it relates to the resistance of a coating towards ethanol which is a very particular aggressive organic solvent. However, enhancing the ER of a coating is a major challenge because ER relates to a coating performance which is such as to resist degradation when exposed to ethanol; coatings exhibiting enhanced ER are highly desirable and enhancing the ER of coatings is a challenging technical task. This challenge becomes more significant if one wishes to also combine enhanced ER with one or both of RWR and WR.

[0008] The WO 2021 / 148563 A1 provided for a multi-aziridine crosslinker composition characterized in that the multi-aziridine crosslinker composition is an aqueous dispersion having a pH ranging from 8 to 14 and comprises a multi-aziridine compound in dispersed form. The WO 2021 / 148563 A1 did not -at least- disclose aziridinyl-functional organic compounds as the latter is disclosed in the specification. The WO 2021 / 148563 A1 dealt with the provision of multi-aziridine crosslinkers which can be delivered and stored in water with a longer shelf life while maintaining sufficient reactivity towards carboxylic acid functional polymers (cf. WO 2021 / 148563 A1 , p. 2, II. 8-10). In addition, the WO 2021 / 148563 A1 did not disclose on how to improve the ER of coatings prepared from aziridinyl-functional organic compounds suitable as crosslinkers in coating compositions, let alone on how an improved ER would be combined with one or both of RWR and WR.

[0009] Therefore, there is a desire for coatings having enhanced ER preferably combined with one or both of RWR and WR, and thus, a technical solution to this challenge is required.

[0010] Such a desired technical solution still represents an unmet need since the solution to such a problem, is particularly challenging and complex. 2024PF30083 FC

[0011] The discussion of documents, acts, materials, devices, articles and the like are included in this specification solely for the purpose of providing a context for the present invention. It is not suggested or represented that any or all these matters formed part of the prior art base or were common general knowledge in the field relevant to the present invention as it existed before the priority date of the present invention.

[0012] SUMMARY OF THE INVENTION

[0013] The invention relates to an aziridinyl-functional organic component. The invention further relates to particles comprising an aziridinyl-functional organic component. The invention further relates to a composition comprising the aziridinyl- functional organic compound of the invention and / or the particles of the invention, and another ingredient. The invention further relates to a kit-of-parts, a cured form of the aziridinyl-functional organic component of the invention, a cured form of the particles of the invention, a cured form of a composition of the invention, and an article.

[0014] The goal of the invention is to provide for coatings having enhanced ethanol resistance, preferably combined with one or both of coating properties such as enhanced red wine resistance and water resistance.

[0015] This goal was surprisingly achieved by the aziridinyl-functional organic component, as described in the specification.

[0016] More particularly, it has surprisingly been found that when the aziridinyl-functional organic component of the invention was used in coating compositions, the coatings derived from said compositions had enhanced ethanol resistance combined with one or both of enhanced red wine resistance and enhanced water resistance.

[0017] The aziridinyl-functional organic component of the invention constitutes a major technological advancement for the paints and coatings industries since the coatings derived from coating compositions containing the aziridinyl-functional organic component of the invention had enhanced ethanol resistance preferably combined with one or both of enhanced red wine resistance and enhanced water resistance when compared with comparable coatings derived from the state-of-the-art. 2024PF30083 FC

[0101] R4 is selected from the group consisting of hydrogen, methyl, and C2-C4 saturated aliphatic hydrocarbyl. with one or more monoepoxides at a temperature in the range of 70 to 80 °C for about 20- 24 h under inert atmosphere, e.g. nitrogen, helium. This reaction (the terms refers to and encompasses any and all of the reactions mentioned just above in this section) takes places at any temperature from 20 to 110 °C, more preferably from 50 to 95 °C, and most preferably from 70 to 90 °C and its progress can be monitored via1H-NMR spectroscopy, and it is carried out till all epoxy groups are consumed; this is monitored and verified by1H-NMR spectroscopy where the characteristic1H-NMR chemical shift of the epoxy protons (2.5 - 3.0 ppm) is disappeared; preferably this reaction is carried out without solvent; however, if desired (for instance to reduce the viscosity), one or more organic solvents, e.g. toluene, 2-methyl-tetrahydrofurane can be used during or after the reaction. If a solvent is used, it is often convenient to first dissolve the monoepoxide in the solvent (or mixture of solvents) before adding the A-P1 to the reaction mixture. The molar ratio of the mol of the aziridine groups of the A-P1 to the mol of the epoxy group of the monoepoxide is at least 1 and at most 8, more preferably at least 1 and at most 4, 2024PF30083 FC even more preferably at least 1.1 and at most 3 and most preferably at least 1.2 and at most 2.2. Once the reaction is completed, the residual A-P1 is distilled off, preferably at a temperature from 60 to 90 °C, more preferably from 65 to 80 °C, and at reduced pressure, for example from 20 to 50 mbar (1 bar= 100000 Pa; 1 mbar= 100 Pa), preferably from 30-45 mbar. Preferably once the reaction is completed, the residual A- P1 is distilled off at reduced pressure from 20 to 50 mbar at 70 °C, more preferably from 30 to 45 mbar at 70 °C. Subsequently, a further distillation step for the removal of any unreacted A-P1 and any other volatiles is carried out at 25 to 40 °C at 2 to 4 mbar, until no A-P1 could be detected by1H-NMR spectroscopy. It is often useful to add an additional solvent to the reaction mixture prior to or during distillation, to facilitate the removal of the excess of A-P1. If desired, a base can be used during the reaction, to reduce possible sources of acid. Bases include both organic bases, like tertiary amines or inorganic bases like sodium or potassium carbonate or for instance calcium hydroxide. The inorganic bases can be filtered off after the reaction is completed.

[0172] 1.3. Determination of the aziridine content

[0173] The aziridine content of the examples and comparative examples was calculated by summing up the amount (in mol) of all AZIROH components in the recipe multiplied by the number of aziridine groups in an AZIROH molecule, and then divided by the total amount (in g) of i) and ii), wherein i) additives (e.g. catalysts) which do not evaporate upon the determination of the solids content, as described in 1.6, and ii) the reactants which react to form the aziridine-functional components; in the specification, and for the purpose of the determination of the aziridine content, the i) and ii) mentioned in this paragraph, are collectively mentioned as ‘entity F’. The aziridine content is given in equivalents aziridine / g entity F (abbreviated as eq aziridine / g entity F).

[0174] For instance, Inventive Example 1 contains 68.32 g of AZIROH-1 (0.3648 mol). Amount aziridine groups is 0.3648 mol. The total amount of entity F is equal to 201.66 g [=69.0 g (Desmodur® W) + 41.22 g (polyTHF®650) + 0.12 g (bismuth(lll) neodecanoate) + 68.32 g (AZIROH-1) and 23.0 g (Ymer™ N-90). The calculated aziridine content of inventive example 1 is: 0.3648 / 201.66 = 0.00181 eq aziridine / g entity F (= 1.81 meq aziridine / g entity F).

[0175] For instance, Comparative Example 1 contains 18.73 g of AZIROH-1 (0.100 mol) and 31.74 g of AZIROH-4 (0.0698 mol). Amount aziridine groups is 0.100 + 2*0.0698 = 0.2396 mol. The total amount of entity F is equal to 100.02 g [=35.14 g (Desmodur® W) + 31.74 g (AZIROH-4) + 0.02 g [bismuth(lll) neodecanoate] + 18.73 g (AZIROH-1) and 14.39 g (Ymer™ N-120). The calculated aziridine content of Comparative example 1 is: 0.2396 / 100.02 = 0.00240 eq aziridine / g entity F (= 2.40 meq aziridine / g entity F). 2024PF30083 FC

[0176] 1.4. Determination of the acid value of a polymer

[0177] The acid value of a polymer is determined according to the ASTM D1639-90(1996)e1. According to the procedure, the sample was dissolved in a good solvent, was titrated with alcoholic potassium hydroxide solution of a known concentration (KOH). The difference in titration volume between the sample and a blank is the measure of the acid value on solids, according to the following equation 1 :

[0178] AV=[(Vblank - Vsample) * NKOH * 56.1] / (W * S / 100)

[0179] (equation 1) wherein

[0180] AV is the acid value (in mg KOH / g solids), biank (in ml) is the volume of KOH solution used in the blank,SamPie (in ml) is the volume of KOH solution used in the sample, NKOH is the normality (in mol / l) of the KOH solution, W is the sample weight in g and S is the solids content of the sample in %. Measurements are performed in duplicate using a potentiometric endpoint on a Metrohm 702SM Titrino titrator (accepting the measurement if the difference between duplicates is < 0.1 mg KOH / g solids).

[0181] 1.5. Determination of the acid content of a polymer

[0182] The acid content (in meq / g solids) of a polymer is calculated from the acid value (in mg KOH / g solids) -determined as described in §1.4- of the polymer, by dividing the acid value by 56.1.

[0183] For instance, the polymer of carboxylic acid functional polyacrylic of example 1.10.1 has an acid value of 31.6 mg KOH / g solids. The acid content of this polymer is : 31.6 / 56.1 = 0.564 meq / g solids.

[0184] 1.6. Determination of the pH

[0185] The pH of a sample was determined according to the ISO 976:2013. Samples were measured at room temperature using a Metrohm 691 pH-meter equipped with a combined glass electrode and a PT-1000 temperature sensor. The pH-meter was calibrated using buffer solutions of pH 7.00 and 9.21 prior to use.

[0186] 1.7. Determination of solids content

[0187] The solids content (wt%) of a composition was determined via method ISO 3251-2019. 1 g of a composition was weighed into an aluminum dish with a diameter of 75 mm. The weight loss of the dispersion was subsequently determined upon drying in an air-circulated oven (the FD 115 air-circulated oven was used and it was obtained from Binder GmbH) at 130 °C for 60 min. 2024PF30083 FC

[0188] 1.8. Determination of the scatter intensity-based average hydrodynamic diameter of the particles (‘Dynamic light scattering- DLS’)

[0189] The scatter intensity-based average hydrodynamic diameter (DH) of the particles was determined using a method derived from the ISO 22412:2017 standard with a Malvern Zetasizer Nano S90 DLS instrument that was operated under the following settings. As material, a polystyrene latex was defined with a Rl 1.590 and absorption of 0.10 with a continuous of a medium of demineralized water with an apparent viscosity of 0.8812 cP and a Rl of 1.332 at 25 °C. Measurements were performed in DTS0012 disposable cuvettes, obtained from Malvern Instruments (Malvern, Worcestershire, United Kingdom). The measurements were performed under a 173 °C back-scatter angle as an average of 3 measurements after 120 seconds equilibration, consisting of 10-15 sub-runs optimized by the machine itself. The focus point of the laser was at a fixed position of 4,65 cm, and data were analyzed using a general-purpose data fitting process. Samples were prepared by diluting 0.05 g sample (aqueous dispersion) in approximately 5 ml of demineralized water. If the sample still looks hazy, it is further diluted with distilled water until it becomes almost transparent.

[0190] 1.9. Determination of the apparent viscosity

[0191] The apparent viscosity was measured at room temperature at 60 rpm, according to ISO 2555-2018 on a Brookfield DVE-LV viscometer (single-cylinder geometry). The spindle was selected from the spindles S61 , S62, S63 or S64, using the lowest-numbered spindle (i.e. the largest spindle) that yields a reading between 10% and 100% torque.

[0192] 1.10. Preparation and assessment of the properties of the coatings

[0193] 1.10.1. Preparation of the aqueous dispersion of a carboxylic acid functional polyacrylic

[0194] An aqueous dispersion of a carboxylic acid functional polyacrylic was synthesized as follows: a 2-L four-necked flask equipped with a dosing funnel, thermometer and overhead stirrer was charged with sodium lauryl sulphate (30 wt% solids in water, 18.6 g of solution) and demineralized water (711 g). The reactor phase was placed under N2 atmosphere and heated to 82 °C. A mixture of demineralized water (112 g), sodium lauryl sulphate (30 wt% solids in water, 37.2 g of solution), methyl methacrylate (325.1 g), n-butyl acrylate (337.7 g) and methacrylic acid (34.88 g) was placed in a large feeding funnel and emulsified with an overhead stirrer (monomer feed). Ammonium persulphate (1.75 g) was dissolved in demineralized water (89.61 g) and 2024PF30083 FC placed in a small feeding funnel (initiator feed). Ammonium persulphate (1.75 g) was dissolved in demineralized water (10.5 g), and this solution was added to the reactor phase. Immediately afterwards, 5% by volume of the monomer feed was added to the reactor phase. The reaction mixture then exothermed to 85 °C and was kept at 85 °C for 5 min. Then, the residual monomer feed and the initiator feed were fed to the reaction mixture over 90 min, maintaining a temperature of 85 °C. After completion of the feeds, the monomer feed funnel was rinsed with demineralized water (18.9 g) and reaction temperature maintained at 85 °C for 45 min. Subsequently, the mixture was cooled to room temperature and brought to pH = 7.2 with AM-solution-6.25 and brought to 39.4 wt% solids with further demineralized water. The carboxylic acid functional polyacrylic has an acid value of 31 .6 mg KOH / g solids and an acid content of 0.564 meq / g solids.

[0197] An amount of 1 ) an aqueous dispersion of an example or a comparative example and an amount 2) of the aqueous dispersion X1 were mixed together under continuous stirring with an upper stirrer; the amounts were calculated such as to correspond to a molar ratio of 0.6 which molar ratio is calculated according to the following equation 2: molar ratio = (M1 * S1 * aziridine content) I (M2 * S2 * acid content) (equation 2) wherein:

[0198] M1 is the weight amount (in g) of a sample to be used of either an AZ-component (as to inventive examples), or of a comparative component to an AZ-component (as to comparative examples);

[0199] M2 is the weight amount (in g) of X1.

[0200] 51 is the solids content (in %) of a sample to be used of either an AZ-component (as to inventive examples), or of a comparative component to an AZ-component (as to comparative examples);

[0201] 52 is the solids content of X1 (in %).

[0202] Upon completion of the mixing, the resulting mixture was stirred for additional 10 min after which it was allowed to settle for 10 min to allow air bubbles to escape, thus obtaining an aqueous coating composition. 2024PF30083 FC

[0203] A 100-micron wet layer of the above prepared aqueous coating composition was applied to a Leneta Form 2C Opacity Chart (obtained from Leneta Company, Inc.) by use of a WC-52 Leneta Wire-Cator™ wire rod (obtained from Leneta Company, Inc.), and dried at 16 °C at 50% air humidity for 1 week to afford the film.
