The present invention relates to an aqueous pigment dispersion that uses a novel dispersant and has excellent dispersibility and dispersion stability. Conventionally, in water-based paints such as emulsion paints and water-soluble resin paints containing pigments, there have been problems such as decreased coloring effect on the painted surface, flattening (floating),
It is well known that undesirable phenomena such as floating (floating mottling) and reduction in gloss occur. For this reason, generally, an aqueous pigment dispersion is prepared by dispersing the pigment in advance with a dispersant, and this is mixed and dispersed in the aqueous paint to be colored to color the aqueous paint. In conventional aqueous pigment dispersions, low molecular weight compounds such as surfactants are used as dispersants, but the dispersants cause damage, that is, secondary adverse effects such as deterioration of coating performance or coating condition. This is unavoidable, and recently oligomers or polymers having a medium molecular weight have been used as dispersants to suppress the deterioration of coating performance. However, when oligomers or polymers are used as dispersants, the amount used is larger than that of low-molecular surfactants, and the use of the resulting aqueous pigment dispersion is dependent on the type of binder used in water-based paints. Therefore, there are drawbacks such as limitations. This goes against the rationalization of paint manufacturing, and there is therefore a strong demand for the development of a water-based pigment dispersion that is common to various water-based paints. Therefore, the present inventors have developed an ideal dispersion that allows pigments to be easily dispersed in small amounts, is compatible with various water-based resins, and is polymeric in itself and does not cause a decline in the coating performance of water-based paints. The present invention was completed as a result of intensive research aimed at developing a particularly difficult aqueous system. Thus, according to the invention, in an aqueous pigment dispersion comprising a pigment, a dispersant and an aqueous medium, the dispersant is (A) a (meth)acrylic resin modified with a synthetic saturated fatty acid or substituted or unsubstituted benzoic acid; monomer
3 to 98 parts by weight (B) Radically polymerizable nitrogen-containing monomer 2 to 97 parts by weight (C) α,β-ethylenically unsaturated carboxylic acid
A polymer obtained by copolymerizing 0.5 to 20 parts by weight and (D) 0 to 91 parts by weight of α,β-ethylenically unsaturated monomers other than (A), (B), and (C) above. An aqueous pigment dispersion is provided, which is a water-soluble pigment dispersion. The polymer used as a dispersant for the aqueous pigment dispersion of the present invention has a lipophilic group on the side chain connected to a main chain containing a hydrophilic nitrogen-containing monomer and an α,β-ethylenically unsaturated carboxylic acid. Because it has a structure that is bonded in a separate form, it has very high pigment dispersion ability. Furthermore, since the polymer contains both basic components derived from nitrogen-containing monomers and acidic components derived from carboxylic acids, it has the advantage that it is possible to disperse a wide range of pigments such as acidic pigments and basic pigments. are doing. Also,
This dispersant has excellent pigment dispersion ability and a relatively low acid value, i.e., the absolute amount of carboxyl groups is small, so it has excellent properties such as corrosion resistance and adhesion, and can form good colored coatings. Obtainable. Hereinafter, the dispersant used in the aqueous pigment dispersion of the present invention will be explained in more detail. (Meth)acrylic monomer (A) modified with synthetic saturated fatty acids or substituted or unsubstituted benzoic acid: Synthetic saturated fatty acids or (meth)acrylic monomers modified with substituted or unsubstituted benzoic acid used in the present invention ) Acrylic monomer (hereinafter referred to as "acid-modified (meth)acrylic monomer") (A), the synthetic saturated fatty acid used as a modifier is obtained from natural fats and oils or fatty acids or petroleum raw materials by ozone oxidation. law,

These synthetic saturated fatty acids or substituted or unsubstituted benzoic acids are introduced into (meth)acrylic monomers as described below by utilizing the reactivity of the existing carboxyl groups. With this introduction,
The above acids may be used alone or in combination of two or more, but generally these acids are used in an amount of 5 to 65% by weight based on the weight of the resulting polymer. %, preferably 10~
It is advantageous to use amounts within the range of 60% by weight. The (meth)acrylic monomer into which such an acid is introduced has a functional group capable of reacting with the carboxyl group of the acid, such as an epoxy group, in the ester residue portion.
Examples include esters of acrylic acid or methacrylic acid containing hydroxyl groups and the like. Therefore, acid-modified (meth)acrylic monomer (A)
One type of (meth)acrylic monomer into which the synthetic saturated fatty acid or substituted or unsubstituted benzoic acid described above is introduced is "acrylic ester or methacrylic ester having an epoxy group" (hereinafter referred to as (sometimes abbreviated as "epoxy-containing (meth)acrylic ester"), and this type of ester includes those containing a glycidyl group in the ester residue of acrylic acid or methacrylic acid, especially glycidyl acrylate and Glycidyl methacrylate is preferred. The acid-modified acrylic monomer (A) using such an epoxy-containing acrylic ester is prepared according to the conventional method, in the presence or absence of a suitable inert solvent, usually in the absence of a solvent, by the synthesis described above. This can be accomplished by reacting a saturated fatty acid or substituted or unsubstituted benzoic acid with an epoxy-containing acrylic ester. The reaction can generally be carried out at a temperature of about 60 to about 220°C, preferably about 120 to about 170°C, and the reaction time is generally about 0.5 to about 40 hours, preferably about 3 to about 10 hours.

In the above reaction, esterification accompanied by cleavage of the oxirane ring occurs between the oxirane group (epoxy group) of the epoxy-containing (meth)acrylic ester and the carboxyl group of the synthetic saturated fatty acid or substituted or unsubstituted benzoic acid. A (meth)acrylic acid ester modified with an acid is obtained. In addition, the (meth)acrylic monomer that is reacted with the above synthetic saturated fatty acid or substituted or unsubstituted benzoic acid to produce another type of acid-modified (meth)acrylic monomer (A) includes: This type of ester includes esters of acrylic acid or methacrylic acid (hereinafter sometimes abbreviated as ``hydroxyl group-containing (meth)acrylic esters'').

The hydroxyl group-containing (meth)acrylic ester is
Usually, it can be used in a proportion of 0.5 to 1.9 mol per mol of the above-mentioned acid, preferably 1.0 to 1.5 mol per mol of the above-mentioned acid. Examples of the esterification catalyst used in the above reaction include sulfuric acid, aluminum sulfate, potassium hydrogen sulfate, p-toluenesulfonic acid, hydrochloric acid, methyl sulfate, and phosphoric acid. Approximately 0.001 or more of the total amount of the above acid and hydroxyl group-containing (meth)acrylic ester

Examples include hexanol. These solvents are based on the total weight of the four copolymer components.
It can be used in a range of 15-90% by weight. Examples of polymerization catalysts include azo compounds, peroxide compounds, sulfides, sulfin compounds, sulfinic acids, diazo compounds, nitroso compounds, redox compounds, and radical initiators that can be used in normal radical polymerization such as ionizing radiation. is used. In the present invention, a substantially satisfactory aqueous pigment dispersion can be obtained even if the molecular weight of the copolymer to be produced changes, but if the molecular weight is too low, there is a risk of deterioration of the physical properties of the water-based paint to be colored. be.
In addition, if the molecular weight is too high, the viscosity will increase, and if the viscosity is lowered, the concentration of the copolymer will decrease and the dispersibility of the pigment will decrease.
The number average molecular weight of the copolymer produced is approximately 500 to approximately
150,000, preferably within the range of about 1,000 to about 100,000. The copolymer resin thus produced can be made water-soluble as it is or after distilling off the solvent. This water solubility can be achieved by a conventional method, for example, by neutralizing the carboxyl groups present in the copolymer resin with a conventionally known neutralizing agent. Examples of neutralizing agents that can be used include ammonia, amines, alkali metal hydroxides, alkali metal carbonates or bicarbonates, and the like.
As the amine, primary or secondary alkylamines; primary, secondary or tertiary alkanolamines; and cycloalkylamines can be used. In addition, hydroxides of alkali metals include potassium hydroxide and sodium hydroxide; carbonates and bicarbonates of alkali metals include potassium carbonate,
Sodium carbonate, sodium bicarbonate, etc. can be used. Among these neutralizing agents, potassium hydroxide and sodium hydroxide are particularly preferred. The neutralization treatment can be easily carried out by a conventional method by adding the neutralizing agent or an aqueous solution thereof to the copolymer resin or its solution obtained as described above. The amount of neutralizing agent used is generally 0.01 to 2.0 equivalents, preferably 0.3 to 2.0 equivalents based on the carboxyl group in the resin.
It is 1.0 equivalent. The water-solubilized polymer thus obtained is used as a dispersant in an aqueous pigment dispersion consisting of a pigment, a dispersant, and an aqueous medium. The amount of the dispersant made of the water-solubilizing polymer used is generally about 1 to 500 parts by weight per 100 parts by weight of the pigment.
Preferably, it can be about 1 to 300 parts by weight.
When the upper limit of this range is exceeded, the balance between coloring power and viscosity of the aqueous pigment dispersion tends to become imbalanced, while when it is outside the lower limit, the dispersion stability of the pigment tends to decrease. The aqueous medium used in the aqueous pigment dispersion of the present invention is essentially water, but if necessary,
For example, if the degree of hydrophilicity of the dispersant is low and sufficient pigment dispersion performance cannot be obtained, a hydrophilic organic solvent can be used in combination. As the hydrophilic organic solvent, those used in the production of the polymer can be used alone or in combination. Furthermore, the pigments used in the aqueous pigment dispersion of the present invention can be inorganic and organic pigments commonly used in this type of pigment dispersion.

(yellow iron oxide, etc.); (3) Sulfide, acetylenide (zinc sulfide) vermilion, cadmium yellow, cadmium red, etc.); (4) Ferrocyanide (dark blue, etc.); (5) chromate (yellow) (lead, zinc chromate, molybdenum lead, etc.); (6) Sulfate-based (precipitated barium sulfate, etc.); (7) Carbonate-based (precipitated calcium carbonate, etc.); (8)
Silicate type (hydrated silicate, clay, ultramarine, etc.); (9) Phosphate type (manganese violet, etc.); (10) Carbonate type (carbon black, etc.); Metal powder type (aluminum powder, bronze powder) , lead powder, etc.), etc.
Examples of organic pigments include (1) nitrone pigments (Naphthol Green B, etc.); (2) nitro pigments (Naphthol Yellow S, etc.); (3) azo pigments (Resol Red, Lake Red C, Fast Yellow, Naphthol Red, etc.); (4) Dyed lake pigments (alkali blue lake, rhodamine lake, etc.); (5)
Phthalocyanine pigment type (phthalocyanine blue,
(6) condensed polycyclic pigments (perylene red, quinacridone red, dioxazine violet, isoindolinone yellow, etc.); The content of the pigment in the aqueous pigment dispersion of the present invention is not particularly technically limited, but is generally about 2 to 90% by weight based on the weight of the dispersion. The aqueous pigment dispersion of the present invention can be prepared by simultaneously mixing the above components in a suitable dispersion device. Examples include ball mills, roll mills, homomixers, sand gliders, sheakers, and attritors. If necessary, conventionally known surfactants and protective colloids can be added to the aqueous pigment dispersion of the present invention. The aqueous pigment dispersion of the present invention thus obtained is
The pigment is extremely uniformly and finely dispersed, and there is almost no aggregation or sedimentation of the pigment particles even when stored for a long time. This is presumed to be because the lipophilic part of the dispersant is adsorbed on the surface of the pigment, and the hydrophilic part dissolves in the aqueous medium, so that the pigment is stably dispersed in the aqueous medium. Therefore, the aqueous pigment dispersion of the present invention has alkyd resins used in water-based paints and inks,
It has good miscibility with conventionally known water-soluble resins, water-dispersible resins, emulsions, etc. such as acrylic resins, epoxy resins, urethane resins, maleated polybutadiene resins, etc., and there is no restriction due to these resins, and it can be used with any of the following. It can also be widely used for coloring water-based paints made of resin. As specific examples of the above-mentioned water-based resins, for example, alkyd resins are synthesized from the same raw materials as conventional solvent-based alkyd resins, and include polybasic acids, polyhydric alcohols,
It is obtained by subjecting oil components to a condensation reaction using a conventional method. Acrylic resins include α,β-ethylenically unsaturated acids (e.g., acrylic acid, methacrylic acid, maleic acid, etc.), (meth)acrylic acid esters (e.g., ethyl acrylate, propyl acrylate, butyl acrylate, methyl methacrylate, etc.). , ethyl methacrylate, propyl methacrylate, butyl methacrylate, etc.) and vinyl aromatic compounds (for example, styrene, vinyltoluene, etc.). Epoxy resins can be produced by synthesizing epoxy esters by reacting the epoxy groups of epoxy resin with unsaturated fatty acids, and adding α,β-unsaturated acids to this unsaturated group, or by combining the hydroxyl groups of epoxy esters with phthalic acid. Examples include epoxy ester resins obtained by a method of esterifying polybasic acids such as or trimellitic acid. In addition, as the urethane resin, polyisocyanate compounds (for example, toluene diisocyanate, diphenylmethane diisocyanate, 1,6
-Hexane diisocyanate, isophorone diisocyanate, etc.) to introduce a urethane group into the resin skeleton, and a carboxyl group using dimethylolpropionic acid or the like. When using the above-mentioned aqueous resin as water-soluble, it is synthesized so that the resin has an acid value of about 35 to 200, and this is neutralized with an alkaline substance such as sodium hydroxide or amine to make it water-soluble. Served for paint. On the other hand, when these resins are used in a self-dispersion type, the acid value of the resin is made into a low acid value resin of about 5 to 35, and this resin is neutralized and used as a water-dispersed paint. In addition, emulsions include emulsifier-dispersed emulsions obtained by dispersing alkyd resins, acrylic resins, epoxy resins, and urethane resins using anionic or nonionic low-molecular-weight surfactants; Emulsion polymerization emulsion obtained by emulsion polymerization of monomers such as acrylic ester, acrylonitrile, styrene, butadiene, vinyl acetate, vinyl chloride; maleated polybutadiene, maleated alkyd resin,
Soap obtained by emulsion polymerization and graft reaction of the above-mentioned monomers using water-soluble resins such as maleated fatty acid-modified vinyl resins, drying oils or semi-drying oil fatty acid-modified acrylic resins, and other water-soluble polymers as emulsion stabilizers. Examples include free emulsions. The aqueous pigment dispersion of the present invention is particularly effective in blending with aqueous pigments made of low acid value water-dispersible resins and emulsions which have poor pigment dispersibility. The blending ratio of the aqueous pigment dispersion of the present invention to the aqueous paint can be varied within a wide range depending on the type of pigment in the dispersion and the degree of coloring required for the final paint, but in general, The pigment dispersion can be blended in an amount of 2 to 100 parts by weight per 100 parts by weight of the resin content of the aqueous paint.
