Description
57 Aqueous and coating compositions, coating, method of preserving an aqueous composition, and coated article. Field of Invention
[001] This application relates to the preservation of coatings and coating compositions by means of additives that exhibit multifunctional effects, including reduced susceptibility to microbial deterioration and improved or maintained paint or coating performance. Background
[002] Coating compositions, such as paints, typically contain four essential ingredients: carrier liquid, binder, pigment, and additives. Each of these ingredients may comprise a single component or several different items mixed into the paint.
[003] The carrier liquid is a fluid component of the coating composition that serves to transport all the other components of the composition. The carrier liquid is part of the wet coating composition and generally evaporates as the coating forms a film and dries on a surface. In latex paints, the carrier liquid is usually water. In oil-based or solvent-based paints, the carrier liquid is usually an organic solvent. The amount and type of carrier liquid are generally determined by the properties of the other paint components.
[004] The binder component of a coating composition enables the coating to form a film and adhere to a substrate, and provides durability to the cured coating, among other benefits. In a water-based coating composition, the binder comprises a polymeric binder, generally selected from (meth)acrylics, vinyl acrylics, styrene acrylics, water-based polyurethane dispersions (PUDs), binders Petition 870250091017, dated 06 / 10 / 2025, p. 15 / 82 / 57 water-based alkyds, water-based alkyd-PUD hybrids or combinations thereof. In the polymeric binder of a water-based coating composition, the polymeric binder is generally provided as an aqueous latex, with latex particles in an emulsion or dispersion in water as the carrier liquid. In a solvent-based paint or coating, the binder or film-forming agent comprises an acrylic-amino, alkyd, polyurethane or epoxy resin.
[005] Pigments give the coating both decorative and protective features, among other benefits. Pigments are dispersed solid particles used to impart various qualities to the paint, including, but not limited to, color, opacity, and durability. The coating may also include other organic or inorganic extenders, which can provide additional performance characteristics, including modifying the surface appearance (e.g., gloss / flatness and luster) of the coating.
[006] Other additives may be included in paints and coating compositions. Additives are typically used in relatively low concentrations in the paint or coating composition compared to the binder, but contribute to various properties of paints and coatings, including rheology, stability, paint performance, and application quality. Paints and coating compositions are complex formulations, and different additives can interact to have unpredictable, favorable, or unfavorable impacts on the various properties of the paint or coating.In the formulation of a paint or coating, the addition or modification of a paint or coating formula with different additives or other components must be carefully balanced so that important properties of the paint or coating, such as washability, abrasion resistance, heat and aging stability, and microbial preservation, to name just a few, are preserved. Petition 870250091017, dated 06 / 10 / 2025, page 16 / 82 / 57, that they be maintained, improved, or subjected only to minimal and tolerable decreases in quality.
[007] Biocides, which are also called antimicrobial agents, are additives that have microbiostatic or microbicidal properties. In coating composition formulations, biocides can have a preservative effect to prevent microbial deterioration in the can or wet state and ensure the stability of the paint or coating composition, and can also provide dry film preservation, whereby a biocide in a dry paint or coating film prevents or mitigates the growth of microbes, usually in the form of mold or fungi, on the coating surface. Deterioration of a coating composition due to microbial contamination or undesirable amounts of microbial growth in the container can cause putrefaction, reduced pH, gas formation, and changes in viscosity that can render the coating composition unusable or give it undesirable properties.As a result, paint and coating compositions must be properly preserved so that they remain usable throughout manufacturing, distribution, and storage.
[008] Several antimicrobial additives are well known and used for various purposes. Antimicrobial additives include organic biocides such as organic acids, phenols, alcohols, and quaternary ammonium compounds. Quaternary ammonium compounds, such as those disclosed in US Patent 9,131,683 B2, act as biocides by damaging cell membranes and killing bacteria. Organic antimicrobial additives additionally include conventional isothiazolinone additives including, but not limited to, benzisothiazolinone (BIT), methylisothiazolinone (MIT), and 2-methyl-4-isothiazolin-3-one (CMIT). While effective biocides for preserving paints, isothiazolinones such as BIT, MIT, and Petition 870250091017, dated 06 / 10 / 2025, page 17 / 82 / 57 CMITs are increasingly exposed to supply chain / manufacturing risks, including limited production sources, as well as potential emerging regulations. There are also inorganic antimicrobial additives, for example, those containing metal ions, such as silver-based, zinc-based (including zinc pyrithiones), and copper-based biocides. Other inorganic antimicrobial additives include phosphates, metal ions, metals, and zeolites or hydroxyapatites containing biocide. These conventional antimicrobial additives may present similar supply chain or regulatory risks, and thus there is a need to find ways to adequately preserve paints and coatings using fewer, or no, conventional biocides.
[009] Summary of the Invention
[0010] Aqueous compositions are disclosed including a carrier liquid, a film-forming polymeric binder, and a nitrogenous organic additive including at least one compound comprising four nitrogen centers, each nitrogen center being linked to at least one other nitrogen center by at least one saturated divalent hydrocarbon linking group. In some embodiments, the aqueous composition is a latex emulsion or polymeric dispersion, paint, coating composition, caulking compound, or sealant. Optionally, the nitrogenous organic additive is a post-addition component of the emulsion, dispersion, paint, coating composition, caulking compound, or sealant.
[0011] In some approaches, the coating compositions of the present disclosure provide maintained or enhanced coating performance characteristics, such as maintained or reduced susceptibility to microbial deterioration, maintained or enhanced washability, maintained or enhanced abrasion resistance, and maintained or enhanced aging or thermal aging stability compared to coating compositions that do not include the nitrogenous organic additive. In some Petition 870250091017, dated 06 / 10 / 2025, page 18 / 82 / 57 approaches, the aqueous compositions of the present disclosure maintain acceptable resistance to microbial growth, despite including reduced amounts of certain known antimicrobial additives.
[0012] The summary of this disclosure is not intended to describe every embodiment disclosed or every implementation of this disclosure. The following description exemplifies illustrative embodiments more particularly. Throughout this disclosure, guidance is provided by means of lists of examples, which may be used in various combinations. In each case, any lists mentioned serve only as a representative group and should not be construed as an exclusive or exhaustive list. Thus, the scope of this disclosure should not be limited to the specific illustrative structures described herein, but extends at least to the structures described by the language of the claims, and to equivalents of those structures. Any of the elements that are positively cited in this descriptive report as alternatives may be explicitly included in the claims or excluded from the claims, in any combination, as desired.Although various theories and possible mechanisms may have been discussed here, in no case should such discussions serve to limit the matter claimed. Definitions
[0013] Unless otherwise specified, the following terms, as used herein, have the following meanings.
[0014] As used herein, the term 1K or one component, when used with reference to a coating composition, means that the coating composition is applied to a substrate in only one part and can cure under ambient or baking conditions without the addition of a second part.
[0015] As used herein, the term 2K or two-component, when used with reference to a coating composition, means Petition 870250091017, dated 06 / 10 / 2025, p. 19 / 82 / 57, states that the coating composition comprises two parts that are kept separate until the time of application. Typically, 2K coating compositions are reactive, with one of said two parts serving to activate the other of said two parts when the parts are combined to initiate the curing or hardening of the 2K coating composition.
[0016] As used herein, the terms adequate preservation or adequately preserved, when used with reference to a composition, mean that the composition passes the microbial challenge test described below.
[0017] As used herein, the term binder resin refers to a polymeric resin that coalesces, cures, or otherwise assists in the formation of a film from a liquid or solid coating composition.
[0018] The term component refers to any compound that includes a specific feature or a specific structure in a composition. Examples of components include compounds, monomers, oligomers, polymers, and organic groups contained therein. One skilled in the art will recognize that this definition of component is distinct from the term used in the context of a one-component or two-component coating composition, as defined above.
[0019] The term double bond is not limiting and refers to any type of double bond between any suitable atoms (e.g., C, O, N, etc.). The term ethylenically unsaturated refers to compounds that include a carbon-carbon double bond (i.e., -C=C-).
[0020] The term film formation means that a composition includes a sufficient quantity of binder so that, when applied to a surface and cured, the composition forms a continuous coating film.
[0021] The term volatile organic compound (VOC - volatile organic Petition 870250091017, dated 10 / 06 / 2025, page 20 / 82 / 57, compound), as defined by the Environmental Protection Agency (EPA) in 40 CFR 51.100(s), refers to any carbon compound, excluding carbon monoxide, carbon dioxide, carbonic acid, metal carbides or carbonates, and ammonium carbonate, that participates in atmospheric photochemical reactions, except for certain exempt compounds identified by the EPA. As used herein, volatile organic compound content (VOC content) in an aqueous composition, such as a coating composition, aqueous polymer binder composition, or other composition, means the weight of VOC per volume of the coating solids. VOC may be recorded, for example, as grams of VOC per liter (g / L). With respect to a latex polymer described herein, VOC may also be recorded as grams of VOC per 100 grams of latex polymer (with reference to grams of solids in the latex).VOC content is measured using the ASTM D6886-18 method with methyl palmitate as a marker.
[0022] As used herein, the term glass transition temperature or Tg refers to the midpoint of the temperature range at which an amorphous solid material undergoes a reversible transition from a glass-like state to a rubber-like state. The glass transition temperature or Tg can be predicted using the Fox equation or measured by differential scanning calorimetry. Unless otherwise indicated, the Tg values described herein are theoretical values predicted using the Fox equation. The application of the Fox equation to estimate the Tg of polymers is well known in the art. Tg can be measured using differential scanning calorimetry. Composition samples for differential scanning calorimetry (DSC) testing are weighed in standard sample trays and analyzed using the standard DSC heat-cold-heat method. A sample is heated at 10 °C per minute from 50 °C to 150 °C, then cooled to Petition 870250091017, dated 06 / 10 / 2025, p. 21 / 82 / 57 -75 °C at 20 °C / min, then stabilized at -75 °C before reheating to 150 °C at 10 °C / min. Glass transition temperatures are calculated from the thermogram of the last heat cycle. The glass transition is measured at the inflection point of the transition.
[0023] Luster may sometimes be called gloss. In a coating, a glossy finish indicates that the surface that has a coating applied to it (i.e., is finished) is shiny or glass-like. The gloss of a surface is described as the reflection of light from the surface that is independent of color. The ASTM D523 method can be used to measure gloss or shine. The prescribed angle at which light is reflected off the surface may vary, but for the purposes of this disclosure, Luster 85 is measured at 85° relative to the light-reflecting surface. The ASTM D523 method can also be used to describe Gloss 60, which is measured at 60° relative to the light-reflecting surface. Gloss may also refer to the intensity of gloss measured at 20, 60, or 85 degrees and is determined according to ASTM D523. One skilled in the art is able to determine relative levels of gloss (low versus high) in the context of each coating.
[0024] The term substantially VOC-free means that the composition contains less than about 50 g / L of VOCs. Unless otherwise indicated, the terms low in VOC and substantially VOC-free are used interchangeably in the present invention. The term essentially VOC-free means that the composition contains less than 5 g / L of VOCs. The terms zero VOC and essentially VOC-free are used interchangeably in the present invention.
[0025] The term substantially free, when applied to components of a composition and not to the VOC content, means that the composition contains no more than about 1%, by weight, of a specific component, based on the total weight of solids in the composition. For example, Petition 870250091017, dated 06 / 10 / 2025, page 22 / 82 / 57: A composition that is substantially free of conventional biocide contains no more than about 1% by weight of conventional biocide as a percentage of the composition's solids weight. A composition that is essentially free when applied to components of a composition and not to VOC content means that the composition contains no more than about 0.04% by weight of the material. A composition that is completely free when applied to components of a composition and not to VOC content means that the composition contains no more than trace amounts of the material as a percentage of the composition's solids base.
[0026] As used herein, the term container means any vessel (with or without a lid or other type of closure system) used to store, mix, tint or color a paint formulation and includes the containers in which paints and coatings are typically marketed and sold. Suitable containers include paint cans, paint bottles, containers made of metal, containers made of plastic and / or other polymeric materials and the like.
[0027] The term abrasion resistance, as used herein, refers to the ability of the surface of a coating film or paint film to resist wear or to maintain its original appearance when rubbed with or against an abrasive surface, typically during cleaning. Abrasion resistance is measured according to ASTM D2486-96 (Standard Test Method for Abrasion Resistance of Wall Paints). As reported according to the standard test method, a higher number of exfoliants indicates greater abrasion resistance.
[0028] The term pigment includes both dispersible and colored solid particulate materials and dispersible or soluble colored coloring materials, the material imparting a visibly perceptible color to a paint or coating when 5% by weight (in the case of a dispersible and colored solid particulate material) or 0.05% by weight (in the case of a Petition 870250091017, dated 06 / 10 / 2025, page 23 / 82 / 57 dispersible or soluble colored dye) of the material is added to (e.g., dispensed in) the paint or coating. The presence or absence of visually perceptible color can be evaluated by preparing paint or coating pull samples with and without the pigment, molding such samples as coated films of 25 micrometers (µm) dry thickness onto the white portion of a BYKGardner paint pull opacity chart No. PA-2811 (available from BYK-Gardner USA) or comparable chart, and examining the coated films under normal interior ceiling light illumination. Pigments can also impart opacity to a coating without significant effect on color.
[0029] The term pigment volume concentration (PVC pigment volume concentration) when used in relation to a paint, dye or colorant means the total percentage of dry coating volume occupied by all inorganic species in the coating. The PVC of a coating composition is the ratio between the volume of pigments (including fillers and functional fillers) and the volume of total non-volatile material (i.e., binder solids) present in the coating.
[0030] The term post-addition component or post-additive refers to a component of a coating composition or aqueous polymer binder composition that may be added at any stage during the mixing of a coating composition or polymer binder composition before application or curing of the composition, but after polymerization of the polymer binder from monomers.
[0031] Unless otherwise indicated, a reference to a (meth)acrylate compound (where meth is in parentheses) is intended to include both acrylate and methacrylate compounds. For example, the term (meth)acrylate polymer independently includes each of the acrylate homopolymers, methacrylate homopolymers, and copolymers that include interpolymerized acrylate and methacrylate monomers. Petition 870250091017, dated 06 / 10 / 2025, page 24 / 82 / 57
[0032] The term multi-stage, as used here in relation to a latex, means that the latex polymer was made using isolated and sequential loads of two or more monomers or mixtures of monomers, or was made using a continuously varying load of two or more monomers. A multi-stage polymer is distinct from a single-stage polymer made using one type of monomer mixed with distinct polymeric starting particles.
[0033] The terms water-based or water-based refer to compositions that include a vehicle that has more than 50% water by weight as a percentage of the total weight of the vehicle.
[0034] The term "on," when used in the context of a coating applied over a surface or substrate, includes both coatings applied directly and indirectly to the surface or substrate, such that an intermediate layer is present between the coating and the surface or substrate. Thus, for example, a coating applied to a primer layer overlying a substrate constitutes a coating applied on the substrate.
[0035] Unless otherwise indicated, the term polymer includes both homopolymers and copolymers (that is, polymers of two or more different monomers).
[0036] The term coating composition encompasses paints and also aerosol coatings, caulking compounds, colorants and sealants. Coating compositions may be suitable for use on internal or external surfaces of buildings or constructions, for example, walls, finishes, floors, platforms, wooden or metal handrails, ceilings, roofs (including metal shingles, asphalt shingles and ceramic shingles), roads, sidewalks, etc.
[0037] The term paint means a coating composition including pigment and binder which, when applied so as to form a Petition 870250091017, dated 06 / 10 / 2025, page 25 / 82 / 57 A thin wet coating film (e.g., 100 pm) on a freshly sanded smooth wood surface will, upon drying, conceal both the grain and texture of the wood and present a new surface with its own appearance.
[0038] The term includes and its variations do not have a limiting meaning when these terms appear in the description and claims.
[0039] The terms preferred and preferred refer to embodiments that may produce certain benefits under certain circumstances. However, other embodiments may also be preferred under the same or other circumstances. Furthermore, mention of one or more preferred embodiments does not imply that other embodiments are not useful and is intended to exclude other embodiments from the scope of the invention or claims.
[0040] As used herein, the terms a, an, the, at least one, at least one, one or more, and one or more are used interchangeably. Thus, for example, a coating composition comprising an additive may be interpreted to mean that the coating composition includes one or more additives.
[0041] Here too, references to numerical ranges by test endpoints include all numbers contained within that range (e.g., 1 to 5 includes 1, 1.5, 2, 2.75, 3, 3.80, 4, 5, etc.). Furthermore, the revelation of a range includes the revelation of all sub-ranges included within the wider range (e.g., 1 to 5 reveals 1 to 4, 1.5 to 4.5, 1 to 2, etc.).
[0042] Reference throughout this descriptive report to aspects, an aspect, some aspects, approaches, an approach, some approaches, a (1) modality, a specific modality, certain modalities or some modalities etc., means that a specific resource, configuration, composition or specific property is described Petition 870250091017, dated 06 / 10 / 2025, p. 26 / 82 / 57, in connection with the modality, is included in at least one modality of disclosure. Therefore, the appearance of these phrases in various parts throughout this descriptive report does not necessarily refer to the same modality of disclosure, although in both cases the same term (e.g., aspect or approach) is present. Furthermore, particular features, configurations, compositions, or characteristics may be combined in any suitable manner in one or more modalities. Detailed description

The polymeric binder is present in the aqueous composition in sufficient quantity to form a continuous film when the aqueous composition is applied to a substrate and allowed to cure. In some embodiments, the aqueous composition may comprise, for example, at least about 17% by weight to about 60% by weight of polymeric solids based on the total weight of the components of the aqueous composition.
[0064] In some embodiments, the polymeric binder is completely free or essentially free of any functional monomeric units comprising reactive ketone moieties that crosslink the polymeric binder during film formation. In some embodiments, such reactive ketone moieties include diacetone acrylamide (DAAM) and acetoacetoxyethyl methacrylate (AAEM).
[0065] In certain preferred embodiments, the polymeric binder is a latex polymer. The latex polymers of the present invention may comprise a single-stage or multi-stage latex polymer. In some embodiments, the aqueous compositions of the present disclosure include a latex polymer that is a multi-stage latex polymer having at least a first stage and a second stage, or a single-stage latex polymer. Petition 870250091017, dated 06 / 10 / 2025, p. 34 / 82 / 57
[0066] A multi-stage latex does not necessarily exhibit two glass transition temperatures measured by differential scanning calorimetry (DSC). For example, a DSC curve for a multi-stage latex made using isolated loads of two or more monomers may exhibit two or more Tgs, but it may exhibit only one Tg. In cases where a DSC curve shows only a single Tg inflection point, or even no Tg inflection point, it can be difficult to determine whether the latex is single-stage or multi-stage, as the observation of a Tg inflection point depends on several factors, including the relative concentration of monomers in a specific stage.Thus, the presence or absence of Tg inflection points on a DSC curve is not decisive as to whether a specific latex polymer is single-stage or multi-stage, but the Tgs of a multi-stage latex can be described in terms of the theoretical Tg values for each monomer stage, as determined by the Fox equation.
[0067] Several methods can be used to prepare the multistage latex described herein, including, for example, sequential monomer feed flow and continuously variable monomer feed techniques. In a sequential monomer feed process, a first monomer or mixture of monomers is fed and polymerization is initiated, and a second monomer (i.e., a different monomer, or a mixture of monomers present in ratios different from those in the first monomer mixture) is fed during later stages of polymerization. In a variable monomer feed process, a first monomer composition is fed, followed by the addition of a second monomer at certain points in the polymerization process and at different rates. By controlling the type of monomers selected for the feed process, a multistage latex suitable for coating compositions or inks can be obtained. Petition 870250091017, dated 06 / 10 / 2025, page 35 / 82 / 57 low VOC can be formed and the latex preferably provides excellent performance characteristics, such as blocking resistance, abrasion resistance and the like, for such coating or paint formulations.
[0068] Preferred multistage latexes include at least two stages (e.g., two, three, or four or more stages) with different Tg values (not considering any Tg that may be associated with an optional starter particle). In some embodiments, each of the at least two stages constitutes at least 15 percent by weight (% by weight), at least 20 percent by weight, at least 25 percent by weight, at least 30 percent by weight, at least 35 percent by weight, or at least 40 percent by weight of the multistage latex, based on the total weight of monomers used to produce the latex (not including the weight of any optional starter particle used).
[0069] In some approaches, the multistage latex described herein is produced by a sequential monomer feed process. In one aspect, polymerization begins with a higher Tg monomer feed stream followed by a lower Tg monomer feed stream and vice versa. In a preferred aspect, polymerization begins with a higher Tg monomer feed stream followed by a lower Tg monomer feed stream.
[0070] In some approaches, the multistage latex described here is produced using different monomer feed streams. The resulting polymer will typically have a DSC curve that does not exhibit Tg inflection points and can be said to have an essentially infinite number of Tg stages. The resulting multistage latex will have a high-to-low Tg gradient, or vice versa, depending on the order in which the high-Tg monomers are fed into the reaction.
[0071] In a preferred approach, multi-stage latex Petition 870250091017, dated 06 / 10 / 2025, page 36 / 82 / 57 described herein is produced by a sequential monomer feed process using at least two distinct monomer feed streams. In one aspect, a high Tg stage (i.e., a hard stage) is fed first into a reactor vessel and a low Tg stage (i.e., a soft stage) is added at a later stage of the process. A multi-stage latex can be formed and, after coalescence, the composition will typically exhibit two distinct Tg values, or at least one Tg corresponding to the monomer stage present in the higher concentration. In some cases, no distinct Tg can be observed or detected by DSC for a monomer or monomer mixture at a specific stage that is present in very small quantities relative to the other monomer or monomer mixture.
[0072] In one approach, multistage latex optionally includes an initial particle phase, i.e., a relatively small monomer or polymer particle, but the initial particle is neither required nor essential for the preparation or for the optimal performance of the multistage latex when used in a coating composition or paint formulation.
[0073] In one approach, the relative positions of the first and second phases can be internal and external, respectively, or vice versa. In another aspect, the first and second phases can be neighbors or adjacent. Without adhering to theory, it is believed that the relative position of the stages of multi-stage latex is influenced by the method used to produce the latex.
[0074] In one approach, by controlling the monomers used for each stage of the sequential monomer feeding process, a multi-stage latex with a desired minimum film forming temperature (MFFT) is obtained. The MFFT is the minimum temperature at which the composition comprising a latex Petition 870250091017, dated 06 / 10 / 2025, page 37 / 82 / 57 of multi-stage will form a continuous film, that is, the temperature below which coalescence does not occur. The MFFT of the composition comprising a multi-stage latex, as described herein, is preferably less than about 30 °C, more preferably less than about 20 °C.
[0075] In some approaches, the latex polymer is a single-stage latex, derived by polymerization in a single-stage process of an emulsion including one or more ethylenically unsaturated monomers. By controlling the type of monomers used in the emulsion polymerization, a single-stage latex suitable for low-VOC coating compositions or paints can be formed.
[0076] In some approaches, by controlling the monomers used in the synthesis of single-stage latex, a single-stage latex composition with the desired MFFT is obtained. The MFFT of the single-stage film-forming binder, as described herein, is preferably less than about 30 °C, more preferably less than about 20 °C.
[0077] The monomers interpolymerized in single-stage latex or multi-stage latex stages separately and preferably include one or more ethylenically unsaturated monomers.
[0078] In some embodiments, the single-stage latex monomers or the first and second stages of multi-stage latex separately and preferably include one or more polymerization products of (i) ethylenically unsaturated monomers, such as, for example, alkyl and alkoxy (meth)acrylates, vinyl esters of saturated carboxylic acids, monoolefins, conjugated dienes, optionally with (ii) one or more monomers, such as, for example, styrene, methyl methacrylate, butyl acrylate, 2-ethylhexyl acrylate, vinyl acetate, acrylonitrile, vinyl chloride and the like. In one embodiment, the latex polymer monomers optionally include one or more polyfunctional (meth)acrylate monomers. In one embodiment, the monomers include Petition 870250091017, dated 06 / 10 / 2025, page 38 / 82 / 57 also one or more ethylenically unsaturated carboxy-functional amide monomers, for example, ureido-functional monomers, such as monomers formed as the product of the reaction between aminoalkyl alkylene urea (for example, aminoethylene urea, for example) with an ethylenically unsaturated carboxylic acid or anhydride (for example, maleic anhydride, for example).
[0079] Suitable ethylenically unsaturated monomers of single-stage latex or multi-stage latex include, for example, acrylic acid, methacrylic acid, methyl acrylate, ethyl acrylate, propyl acrylate, butyl acrylate, 2-ethylhexyl acrylate, methyl methacrylate, ethyl methacrylate, propyl methacrylate, butyl methacrylate, 2-ethylhexyl methacrylate, hydroxyethyl acrylate, hydroxyethyl methacrylate, hydroxybutyl acrylate, hydroxybutyl methacrylate, glycidyl methacrylate, 4-hydroxybutyl acrylate, glycidyl ether, or a dialkyl itaconate, such as dimethyl itaconate, diethyl itaconate, dipropyl itaconate, or dibutyl itaconate, methacrylate of 2-(acetoacetoxy)ethyl (AAEM), diacetone acrylamide (DAAM), acrylamide, methacrylamide, methylol (meth)acrylamide, styrene, α-methyl styrene, vinyl toluene, vinyl acetate, propionate, allyl methacrylate and mixtures thereof.Preferred monomers include styrene, methyl acrylate, methyl methacrylate, ethyl acrylate, methacrylic acid, DAAM, AAEM, n-butyl acrylate, tert-butyl acrylate, tert-butyl methacrylate, n-butyl methacrylate, itaconic acid esters, vinyl acetate, 2-ethylhexyl acrylate, biorenewable monomers and the like.
[0080] In some approaches, the latex polymer is completely free or essentially free of any functional monomeric units comprising reactive ketone moieties that crosslink the latex polymer during film formation. In some embodiments, such reactive ketone moieties include diacetone acrylamide (DAAM) or 2-(acetoacetoxy)ethyl methacrylate (AAEM). Petition 870250091017, dated 06 / 10 / 2025, page 39 / 82 / 57
[0081] Suitable polyfunctional (meth)acrylate monomers, such as, for example, di-, tri- and tetra-functional acrylates, such as dipropylene glycol diacrylate (DPGDA), glyceryl propoxylate triacrylate (GPTA), pentaerythritol tetraacrylate, dipentaerythritol tetraacrylate, mixtures thereof and the like. Preferred polyfunctional acrylate monomers include pentaerythritol tetraacrylate, dipentaerythritol tetraacrylate and the like.
[0082] In some approaches, the latex polymer is formed from at least 80%, by weight, of two or more monomers selected from methyl methacrylate, ethyl acrylate, vinyl acetate, tert-butyl methacrylate, n-butyl methacrylate, styrene, tert-butyl acrylate, n-butyl acrylate, 2-ethylhexyl acrylate, methyl acrylate and itaconic acid esters, based on the total weight of monomers used to form the latex copolymers (and not considering any optional starting particles used).
[0083] In some approaches, the latex polymer is formed from at least 90%, by weight, of three or more monomers selected from methyl methacrylate, ethyl acrylate, vinyl acetate, tert-butyl methacrylate, n-butyl methacrylate, styrene, tert-butyl acrylate, n-butyl acrylate, 2-ethylhexyl acrylate, methyl acrylate and itaconic acid esters, based on the total weight of monomers used to form the latex polymers (and not considering any optional starting particles used).
[0084] Suitable ureido-functional monomers include, for example, monomers with the functionality -NR—(C=O)—NH—, where R can be H, substituted or unsubstituted C1-C10 alkyl, cycloalkyl or substituted or unsubstituted C3-C6 heteroalkyl and the like. Without adhering to theory, it is believed that ureido-functional monomers promote the wet adhesion of the coating compositions and coating and dye systems described herein to a substrate.
[0085] In certain approaches, latex copolymers (either Tg of Petition 870250091017, dated 06 / 10 / 2025, page 40 / 82 / 57. Single-stage, multi-stage, or gradient polymerization (STP) is typically produced using starter particles as a nucleating agent for polymerization. Such starter particles may be in the form of particulate inorganic starter particles (e.g., clay or glass particles), pre-formed particulate polymer starter particles (latex or non-latex polymer starter particles), or locally formed particulate polymer starter particles. The polymer starter particle may be an emulsion polymerized starter particle, but does not encompass polymeric surfactant. In certain embodiments, the starter particles are used in an amount not greater than 10% by weight, or not greater than 5% by weight based on latex polymer solids in the final latex.
[0086] In the present invention, whether the inorganic particulate starter particle, the pre-formed particulate polymer starter particle, or the locally formed particulate starter polymer, such starter particles shall not be considered as providing a stage of a multi-stage polymer or as providing a basis for designating a single-stage polymer or gradient Tg polymer made using such starter particle polymer as a multi-stage polymer.
[0087] In certain approaches, the latex copolymers of the present invention may additionally include crosslinking monomers with the ability to further react with a polymer chain at some point after the initial formation of the latex copolymer (e.g., during coating curing). The crosslinking reaction may occur through the application of energy, for example, through heat or radiation. Or, dyeing may activate the crosslinking polymer through changes in pH, oxygen content, solvent or vehicle evaporation, or other changes that cause a reaction to occur. Several chemicals are known in the art to produce crosslinking in latex. When used, one or more such crosslinking monomers are typically included in the copolymer. Petition 870250091017, dated 06 / 10 / 2025, page 41 / 82 / 57 latex in an amount of at least about 0.1% by weight, at least about 1.0% by weight, at least about 2% by weight, at least about 2.5% by weight, at least about 3% by weight, at least about 4% by weight, or at least about 5% by weight, based on the weight of one or more crosslinking monomers relative to the total weight of monomers used to form the latex copolymer. Although the amount of one or more such crosslinking monomers may vary widely, typically one or more crosslinking monomers are present in the latex copolymer in an amount of about 10% by weight or less, about 9% by weight or less, about 8% by weight or less, about 7% by weight or less, about 6% by weight or less, or about 5% by weight or less, based on the weight of one or more crosslinking monomers relative to the total weight of monomers used to form the latex copolymer.
[0088] Suitable examples of crosslinking carbonyl-containing monomers include acrolein, metacrolein, diacetone acrylamide, diacetone methacrylamide, 2-butanone methacrylate, formyl styrol, diacetone acrylate, diacetone methacrylate, acetonitrile acrylate, acetoacetoxyethyl methacrylate, acetoacetoxyethyl acrylate, and vinylacetoacetate. These monomers do not normally affect crosslinking until during final film formation, for example, when the aqueous polymer emulsion simultaneously contains a suitable added amount of a polyamine compound as a crosslinker. Particularly suitable compounds of this type are the dihydrazides and trihydrazides of aliphatic and aromatic dicarboxylic acids with 2 to 20 carbon atoms. Polyamine compounds useful as crosslinkers for carboxyl functional groups include those that have an average of at least two carbonyl-reactive groups of the formula NH2 and carbonyl-reactive groups derived from such groups.Examples of useful amine functional groups include R-NH2, RO-NH2, RON=C<, R-NHC(=O)-O-NH2, where R is alkylene, alicyclic or aryl and can be. Petition 870250091017, dated 06 / 10 / 2025, page 42 / 82 / 57 replaced. Representative useful polyamines include ethylenediamine, isophorone diamine, diethylenetriamine, and dibutylenetriamine.

Representative useful polyhydrazides include oxalic dihydrazide, adipic dihydrazide, succinic dihydrazide, malonic dihydrazide, glutaric dihydrazide, phthalic or terephthalic dihydrazide, and itaconic dihydrazide. In addition, water-soluble hydrazines, such as ethylene-1,2-dihydrazide, propylene-1,3-dihydrazide, and butylene-1,4-dihydrazide, can also be used as one of the crosslinking agents.
[0089] Examples of suitable commercially available latex polymer dispersions of a film-forming binder include EPS 2720 and EPS 2799 available from Engineered Polymer Solutions of Marengo, IL, USA.
[0090] In a preferred embodiment, the invention described herein includes a latex copolymer that is a single-stage latex. In one aspect, the single-stage latex is formed from monomers that include about 20 to 60, preferably 30 to 55 percent by weight of methyl methacrylate; 0 to 40, preferably 10 to 30 percent by weight of 2-ethylhexyl acrylate; 10 to 60, preferably 15 to 55 percent by weight of butyl acrylate; about 0 to 30, preferably 10 to 20 percent by weight of butyl methacrylate; and about 0 to 10, preferably 1 to 5 percent by weight of methacrylic acid.
[0091] The aqueous compositions of the present disclosure may be latex-based coating compositions. Thus, in some embodiments, at least a majority (i.e., more than 50% by weight), more preferably substantially all or all of the resin solids in the coating compositions are latex polymers. Typically, the coating compositions include at least 20% by weight, at least 30% by weight, at least 40% by weight, or at least 50% by weight of solids. Petition 870250091017, dated 06 / 10 / 2025, page 43 / 82 / 57 latex polymers, based on the total solids of the coating composition. Certain high-gloss deep base coats may include 80% by weight or more of latex polymer solids. Although the upper amount of latex copolymer included in the coating composition may vary widely (e.g., depending on the amount of pigment included), typically coating compositions will include less than 90% by weight of latex polymer solids, based on total solids.
[0092] In certain approaches, the polymeric binders of the present invention may additionally include one or more bio-based monomers. Bio-based, as used herein in relation to monomers, refers to monomers that are preferably obtained from biorenewable olefinically unsaturated monomers. Such biorenewable olefinically unsaturated monomers have a carbon-14 (C-14) that is significantly higher than olefinically unsaturated monomers derived from fossil fuels. This is because C-14 has a relatively short half-life on the age scale of fossil fuel-based materials.Thus, biorenewable monomers, as used herein, mean monomers for which the C-14 isotope content is comparable to the average C-14 content in atmospheric CO2, as measured by the ASTM D6866 method, or such monomers having at least about 1.5 dpm / gC (disintegrations per minute per gram of carbon), at least 2.5 dpm / gC, or at least 3.0 dpm / gC of C-14, as measured by liquid scintillation counting.
[0093] Exemplary biobased monomers include itaconic acid esters, bioderivative (meth)acrylic acid, and alkyl (meth)acrylic acid. In embodiments, the biobased monomers constitute at least 20% by weight, at least 30% by weight, or at least 40% by weight of the polymeric binder, by weight, of all interpolymerized monomers.

The components may be added to a polymer binder composition before, during, or after the completion of polymerization, or they may be added to another aqueous composition as a post-addition. The additional components or additives may be added to the reaction mixture of monomers used to produce a polymer binder, to an aqueous polymer binder composition, or to a coating or paint composition that includes or will include the polymer binder. Suitable additives are known to those skilled in the art and include, but are not limited to, for example, surfactants, open-time agents, pH adjusters, initiator and complement solutions, crosslinking agents, preservatives, defoaming agents, anti-corrosion agents, thixotropes, rheology modifiers, colorants, and matting agents and the like.Additives may include one or more ingredients added to a paint or coating to modify its properties or improve its performance during storage, handling, application, and other subsequent stages. Desirable performance characteristics of a paint or coating include, for example, chemical resistance, hardness, gloss, reflectivity, appearance, and / or a combination of such properties and other similar properties. Preferred performance-enhancing additives include lacquers, waxes, matting agents, anti-scratch additives, abrasion additives, and the like.
[0095] Pigments and fillers can also be added to a coating composition (through pigment grinding) to provide a desired opacity, concealment, or PVC characteristics. Without delving into theory, it is generally understood that lower PVC coatings exhibit higher gloss and greater abrasion durability because such Petition 870250091017, dated 06 / 10 / 2025, p. 45 / 82 / 57 coatings contain a higher proportion by volume of polymeric binder, which is generally believed to provide gloss and durability to cured coatings.

In preferred embodiments, the pigments may comprise inorganic pigments, such as titanium dioxide.

In some approaches, the coating compositions comprise more than 10% titanium dioxide based on the total solids present in the composition. Other colored pigments or dyes may also be added to the coating, alone or in combination, to produce a wide range of colored coatings. Suitable additional pigments may include calcium carbonate, talc, clay, silicates, aluminum silicates, calcium metasilicates, aluminum and potassium silicates, magnesium silicates, barium sulfates, nepheline syenite, feldspar, zinc oxides or sulfides, or others known to those skilled in the art.These additional colored pigments may be included in amounts of up to about 30% by weight, for example, from about 10% to about 20%, based on the total solids present in the compositions. In some cases, pigments may also refer to functional fillers that are water-insoluble solids. Such functional fillers may include solids that provide additional functional characteristics to the coating, for example, intumescent ingredients such as ammonium polyphosphates, melamines, pentaerythritol, and similar compounds. In a useful embodiment, the coating composition of the present invention is substantially free or entirely free of intumescent ingredients.

[00172] The preservative efficacy is tested through the microbial challenge test. As conducted in this document, the microbial challenge test is carried out by subjecting each composition to the microbial challenge test in a manner materially similar to the test protocol detailed in ASTM D2574 - 16 Standard Test Method for Resistance of Emulsion Paints in the Container to Attack by Microorganisms (2016). The preservative test used in the present invention is described below. Discrepancies with ASTM D2574 are included in this description.
[00173] Duplicate, 50 mL samples of each of the sample compositions (each sample composition including a different variation of nitrogen, organic additive, and conventional biocide concentration) were taken and each of the duplicate samples inoculated with: (Challenge 1) 5.0 mL of pooled culture at approximately 109 CFU / mL on day 0, resulting Petition 870250091017, dated 06 / 10 / 2025, page 65 / 82 / 57 at a final concentration of approximately 10⁸ CFU / mL within the sample; (Challenge 2) 2.5 mL of pooled culture at approximately 10⁹ CFU / mL on day 7, resulting in a final concentration of approximately 10⁸ CFU / mL within the sample; and (Challenge 3) 1.25 mL of pooled culture at approximately 10⁹ CFU / mL on day 14, resulting in a final concentration of approximately 10⁸ CFU / mL within the sample. Immediately after inoculation, each sample was then incubated at 30 °C ± 2 °C. For each sample, duplicate spread plates were made at 72 hours and 7 days of incubation by spreading 0.1 mL of the sample uniformly onto a tryptic soy agar plate using aseptic techniques. Each spread plate, thus prepared, was then incubated for a further 72 hours at 30 °C ± 2 °C and microbial growth observed at that time.The challenge test was also performed against negative controls, which are agar plates with bacterial challenge but no ink applied (not to be confused with negative control ink). The results of the negative control spread plate test are conducted as a process check to assess possible experimental errors and are not reported in the results below. Bacterial survival is quantified according to the rating scale shown below in TABLE 1. A total score for the microbial challenge test is determined by calculating the average of the 7-day sample ratings for the third challenge for a given composition. Compositions with a total microbial challenge test score of 6 or less (i.e., developing on average less than 1x10³ CFU / mL showing Moderate contamination) are considered to have passed the microbial challenge test and are therefore properly stored.
