Description [0001] The present invention relates to an aqueous composition comprising a complex of a polyvalent metal complexed by at least one carbonate ligand and at least one carboxylic acid ligand, and to the use of said composition as insolubilizing agent in coating baths for the treatment of fiber-based substrates, like paper, board, non woven and textiles.
[0002] US 4,350,788 teaches that zinc oxide pigments can be used to crosslink adhesive polymers. It is known that zinc oxide pigments can be used to render insoluble, in aqueous solution, synthetic binders, such as latexes or polyvinyl alcohol, and to form insoluble films, thus improving the resistance to water, to friction, to heat and to solvents.
[0003] However, as the zinc oxide pigment, in its solid form, provides only a limited reactive surface, the use of these powders has the disadvantage of providing only very limited efficiency. Thus, the use of these pigments does not give satisfactory results, particularly as regards the resistance of the coating to wet rub.
[0004] US 3,740,366 and EP 0 182 628 teach that aqueous polyvalent metal complexes, like zinc diglycinate (ZDG), can be used to render insoluble, in aqueous solution, synthetic binders, such as latexes or polyvinyl alcohol, and to form insoluble films, thus improving the resistance to water, to friction, to heat and to solvents.
[0005] These polyvalent metal diglycinate solutions are used in numerous technological fields, in particular in aqueous ink and paint formulations and possibly in coating baths intended for the coating or impregnation of paper or board in order to improve the appearance, the wet abrasion resistance, the picking, the strength and the ability to receive printing.
[0006] However, the use of these solutions has the disadvantage of providing only very limited efficiency. Thus, the use of these compositions does not give satisfactory results, particularly as regards the resistance of the coating to wet rub.
[0007] WO 99/06478 teaches that polyvalent metal complexes, such as zinc diacetate (ZDA) solutions, can be used to crosslink polymers. It is known that aqueous compositions of these complexes can be used to render insoluble, in aqueous solution, synthetic binders, such as latexes or polyvinyl alcohol, and to form insoluble films, thus improving the resistance to water, to friction, to heat and to solvents. In WO 99/06478 it is described that these aqueous compositions comprising a polyvalent metal complex, like zinc diacetate, are used in aqueous polymer dispersions.
[0008] US 2009/317549 A relates to a composition comprising a water-soluble salt of a divalent metal, a complexing agent for the divalent metal and an optical brightener.
[0009] However, these compositions are not used in pigmented coating baths intended for the coating or impregnation of paper or board, as the use of these compositions has the disadvantage of showing strong incompatibilities with standard pigmented coating baths of paper and textile industries. This incompatibility results in the destabilization of common coating baths and strong increases of viscosity, rendering the coating baths unusable for application.
[0010] It was therefore an object of the present invention to provide novel aqueous compositions of polyvalent metals in complexed form to be used in the textile and/or paper industry, in particular compositions being compatible with standard pigmented coating baths and providing coatings with an improved resistance to wet rub.
[0011] This object is solved by the aqueous composition according to claim 1.

[0046] In a particular embodiment, the composition further comprises at least one additive. Preferably, said at least one additive is selected from the group consisting of stabilizing agents.
[0047] The stability of the aqueous compositions of the present invention can be improved by the addition of a stabilizing agent as described in the state of the art. In one embodiment, the stabilizing agent is selected from polyacids, such as tartaric acid. The stabilizing agent is advantageously added in the proportion of 1 to 2% approximately with respect to the weight of the final solution. The stabilizing agent may be added before the reaction between the zinc compound and the carbonate or after, preferably before the reaction.

An insolubilizing agent functions to improve the surface characteristics of fiber-based products treated with a coating bath comprising said insolubilizing agent, in particular to improve the wet abrasion resistance of said fiber-based product.
[0059] According to a preferred embodiment of implementing the invention, the insolubilizing agent is a zinc based aqueous composition comprising a potassium and/or ammonium hydrogenocarbonate and glycolic acid and /or glycine.
[0060] In the present invention, the coating bath can be: • either deposited at the surface over the fiber-based product in one or more layers while limiting the penetration inside the surface to be treated, an operation commonly known as coating; • or brought into contact with the fiber-based product with the objective of obtaining penetration inside the fiber-based product in one or more stages, an operation commonly known as impregnation.
[0061] The binders can be of natural or synthetic origin.
[0062] Mention may be made, among natural binders, of starch, modified starch (for example oxidized or modified by enzymes), soy protein and casein.
[0063] More commonly, use is made of synthetic binders, such as styrene/butadiene latexes, polyvinyl acetate latexes, styrene/acrylate and acrylate latexes or polyvinyl alcohol.
[0064] According to a preferred aspect, the binders used in the present invention can be chosen from functionally modified latexes, for example latexes modified with hydroxyl groups, particularly with carboxyl groups, in particular sodium carboxylate groups. Mention may be made, by way of example, of the styrene/butadiene DL 950 latex sold by Dow.
[0065] The coating baths which can be used in the present invention can also comprise additives, such as dispersants, viscosity modifiers (carboxymethylcellulose or hydroxyethylcellulose, for example), lubricating agents, bactericides, pH control agents, repellents, gloss agents, dyes or antifoaming agents.
[0066] The pH of the said coating baths is generally between 7 and 9, preferably between 7 and 8.7.
[0067] Generally, the amount of insolubilizing agent of the present invention in the coating bath is between 1 and 20 parts as is per 100 parts of binder under dry conditions, preferably between 3 and 15 parts as is per 100 parts of binder under dry conditions.
[0068] The coating bath is applied by methods known to the person skilled in the art. Mention may be made, by way of example, of the process with an applicator roll, size press or premetering size press.
[0069] In another aspect, the present invention relates to a method for treating a fiber-based substrate, preferably paper, board, non woven or textiles, preferable a cellulose-based product, in which a coating bath comprising at least one binder, an insolubilizing agent and a pigment, is applied at the surface of the said fiber-based product, characterized in that the insolubilizing agent is an aqueous composition comprising a complex comprising at least one polyvalent metal, wherein said at least one polyvalent metal is complexed by at least one carbonate ligand and at least one carboxylic acid ligand, as described above. Preferably, said insolubilizing agent is a zinc based aqueous composition comprising a carbonate and a carboxylic acid.
[0070] In another aspect, the present invention relates to at a method for treating a fiber-based substrate, like a cellulose-based product, preferably paper or board, non woven or textiles, in which a coating bath comprising at least one binder, an insolubilizing agent and optionally a pigment is brought into contact with said fiber-based product, characterized in that that the insolubilizing agent is an aqueous composition comprising at least one polyvalent metal, wherein said at least one polyvalent metal is complexed by at least one carbonate ligand and at least one carboxylic acid ligand, as described above. Preferably, said insolubilizing agent is a zinc based aqueous composition comprising a carbonate and a carboxylic acid, as described above.

APPLICATION EXAMPLES
[0111] Use was made of a calcium carbonate sold by Omya (Hydrocarb® 90), a kaolin sold by Huber Engineered Materials (Hydragloss®), a styrene/butadiene latex sold by Dow (DL 950), and carboxymethylcellulose (CMC) sold by Noviant (Finfix® 10).
[0112] Various formulations FOto F14were prepared, the compositions of which are given in Tables 1.1 and 1.2 below. The amounts are given as dry parts.
[0113] The formulation F0 does not comprise an insolubilizing agent.
[0114] The formulation F1 corresponds to the use of a commercial nanodispersion of zinc oxide (Comparative Example υ- ΙΟ115] The formulation F2 corresponds to the use of a zinc dicarbonate composition (Comparative Example 2).
[0116] The formulation F3 corresponds to the use of a zinc diacetate composition (Comparative Example 3).
[0117] The formulation F4 corresponds to the use of a commercial zinc diglycinate (Comparative Example 4).
[0118] The formulation F5 corresponds to the use of a zinc, glycinate and carbonate composition, according to the invention, with molar ratio of 50 % of ammonium hydrogenocarbonate and 50 % of glycinate. (Example 5).
[0119] The formulation F6 corresponds to the use of a zinc, glycinate and carbonate composition, according to the invention, with molar ratio of 40 % of ammonium hydrogenocarbonate and 60 % of glycinate. (Example 6).
[0120] The formulation F7 corresponds to the use of a zinc, glycinate and carbonate composition, according to the invention, with molar ratio of 30 % of ammonium hydrogenocarbonate and 70 % of glycinate. (Example 7).
[0121] The formulation F8 corresponds to the use of a zinc, glycinate and carbonate composition, with molar ratio of 20 % of ammonium hydrogenocarbonate and 80 % of glycinate. (Example 8).
[0122] The formulation F9 corresponds to the use of a zinc, glycinate and carbonate composition, with molar ratio of 10 % of ammonium hydrogenocarbonate and 90 % of glycinate. (Example 9).
[0123] The formulation F10 corresponds to the use of a zinc, lactate and carbonate composition, with molar ratio of 50 % of ammonium hydrogenocarbonate and 50 % of lactic acid. (Example 10).
[0124] The formulation F11 corresponds to the use of a zinc, lactate and carbonate composition, with molar ratio of 30 % of ammonium hydrogenocarbonate and 70 % of lactic acid. (Example 9). TABLE 1.1 (= Comparative examples 1 to 4)
TABLE 1.2 (= Examples according to the invention)
(continued)
[0125] The viscosity of each formulation was measured.
[0126] The viscosities were measured with a Brookfield viscometer, at a speed of 100 rpm, and are expressed in mPa.s. Viscosities must stay between 700 and maximum 1000 mPa.s. The results obtained are reported in Tables 2.1 and 2.2 below. When an important viscosity increase is observed, destabilization of the coating bath is also noted, showing the incompatibility of the insolubilizing agent with the coating bath. TABLE 2.1 (= Comparative examples 1 to 4)
[0127] The analysis of the results mentioned in Table 2.1 shows that, with respect to the coating slips prepared according to the techniques of the prior art, the composition F 2, using Zinc Dicarbonate (ZDC), the composition F 3, using Zinc Diacetate (ZDA), both used as comparative examples, give visual destabilisation of the bath, making it not usable for application. Zinc Dicarbonate (ZDC) and Zinc Diacetate (ZDA), both described in the state of art, are not usable. TABLE 2.2 (= Examples according to the invention)
[0128] The analysis of the results mentioned in Table 2.2 shows that compositions according to the invention (examples 5 -11) do not have the drawback to destabilize the bath and allow to obtain usable baths.
[0129] In the examples, use was made of uncoated paper exhibiting a grammage of 80 g/m2.
[0130] The paper was coated with the formulations F0,F4toF11 with a deposition of approximately 20 g/m2 using a threaded rod, followed by oven drying at 105°C in an oven for 2 minutes.
[0131] The Taber wet abrasion was subsequently determined on the coated paper.
[0132] The Taber wet abrasion was carried out according to amended French Standard Q 03-055, with annular test specimens with outer and inner diameters of 120 and 7 mm respectively, with 10 revolutions, CS O wheels, under a pressure of 1N, in the presence of 10 ml of water, followed by rinsing with 10 ml of water; these 20 ml of water are collected and made up to 25 ml with water and then the turbidity of these 25 ml of water is determined with a Hach turbidimeter. The turbidity found is expressed in NTU units (the lower the turbidity values, the better the wet abrasion resistance of the coating) and the results obtained are reported in Table 3 below. TABLE 3 Turbiditv values
[0133] The analysis of the results mentioned in table 3 shows, that with respect to the coating slips prepared according to the prior art (comparative formulation F4, using ZDG cannot provide a coating having a sufficient wet abrasion resistance.
[0134] The formulations F5 - F11 according to the present invention, however, provide coatings having an improved wet abrasion resistance.
[0135] Other advantages of the composition according to the present invention are a very rapid preparation and only a very slight smell of ammonia.
