This invention relates to paper coating compositions that provide improved coated paper. For details, use aliphatic conjugated diene monomer 19.5~ as the first stage.
60 parts by weight, ethylenically unsaturated carboxylic acid monomer
0.5 to 10 parts by weight, and alkenyl aromatic monomer,
30 to 80 parts by weight of one or more monoolefin monomers selected from ethylenically unsaturated carboxylic acid alkyl ester monomers, monomers containing hydroxyalkyl groups, and vinyl cyanide monomers A part of the monomer mixture in the first stage is used in an emulsion polymerization such that the total amount of the monomer mixture is at least 45 to 99 parts by weight, and in the presence of the emulsion copolymer, as a second stage,
Consists of 99 to 75% by weight of an emulsion copolymer latex with a heterogeneous double structure obtained by emulsion copolymerizing the remainder of the monoolefin monomer and 1 to 25% by weight of a specific alkali-soluble copolymer. It is an object of the present invention to provide a paper coating composition having excellent printability, which is characterized in that the main binder is a dispersion of the present invention. In the past, attempts have been made to improve the printing suitability of coated paper by variously improving binders used in coating compositions. Starch, casein, as a natural binder
Styrene as a synthetic binder for soybean protein, etc.
Butadiene copolymer, carboxylated styrene
Butadiene copolymers, ester copolymers of acrylic acid or methacrylic acid, vinyl acetate copolymers, and copolymers made by polymerizing them with other copolymerizable monomers are used and improved. It has been. Conventional binders include those that use a combination of a synthetic binder and a natural binder, and those that use a synthetic binder alone, and have been selected and used according to the requirements of each. However, conventional binders have not been sufficiently satisfactory in printing suitability and surface smoothness of coated paper. The present invention provides a coating composition that improves the above-mentioned drawbacks. That is, in the first step (A), 19.5 to 60 parts by weight of an aliphatic conjugated diene monomer, 0.5 to 10 parts by weight of an ethylenically unsaturated carboxylic acid monomer, an alkenyl aromatic monomer, and an ethylenically unsaturated carbon One or more monoolefin monomers selected from acid alkyl ester monomers, hydroxyalkyl group-containing monomers, and vinyl cyanide monomers 30
A portion of ~80 parts by weight is used so that the total amount of the monomer mixture in the first stage is at least 45 to 99 parts by weight, emulsion polymerization is carried out, and in the presence of the emulsion copolymer, a monoolefin-based 99 to 75% by weight of an emulsion copolymer latex having a heterogeneous double structure obtained by emulsion copolymerizing the remainder of the monomers (alkali-insoluble latex) and (B) 0 to 40% by weight of vinyl acetate monomer parts, unsaturated carboxylic acid monomer 10~
40 parts by weight, 10 to 70 parts by weight of unsaturated carboxylic acid alkyl ester monomer, 1 to 10 parts by weight of vinyl cyanide monomer
25 parts by weight, 0 to 0 amide monomer of unsaturated carboxylic acid
A paper coating composition characterized in that a dispersion comprising 1 to 25 parts by weight of an alkali-soluble copolymer comprising 10 parts by weight and 0.5 to 10 parts by weight of a monomer containing a hydroxyalkyl group is used as the main binder. It is. The alkali-soluble copolymer used in the present invention includes 0 to 40 parts by weight of vinyl acetate monomer, 10 to 40 parts by weight of unsaturated carboxylic acid monomer, and 10 to 70 parts by weight of unsaturated carboxylic acid alkyl ester monomer. 1 to 25 parts by weight of a vinyl cyanide monomer, 0 to 10 parts by weight of an amide monomer of unsaturated carboxylic acid, and 0.5 to 10 parts by weight of a monomer containing a hydroxyalkyl group. As an aliphatic conjugated diene monomer,
Examples include 1.3-butadiene, 2-methyl-1.3-butadiene, and 2-chloro-1.3-butadiene, which may be used singly or in combination of two or more. The aliphatic conjugated diene monomer used in the copolymer (A) is used in an amount of 19.5 to 60 parts by weight, but if it is less than 19.5 parts by weight, the adhesive strength decreases. Moreover, if it exceeds 60 parts by weight, water resistance will decrease. Examples of ethylenically unsaturated carboxylic acid monomers include acrylic acid, methacrylic acid, fumaric acid, maleic acid, and itaconic acid. The above carboxylic acid monomers can be used alone or in combination of two or more. The ethylenically unsaturated carboxylic acid monomer used in the copolymer (A) is used in an amount of 0.5 to 10 parts by weight.
If it is less than 0.5 parts by weight, the adhesive strength and mechanical stability of the latex will be reduced, and if it exceeds 10 parts by weight, the viscosity of the latex will become too high, causing handling problems. Alkenyl aromatic monomers include styrene, α-methylstyrene, vinyltoluene, divinylbenzene, and the like. Alkenyl aromatic monomers are effective in imparting stiffness and adhesion to synthetic copolymer latexes. Ethylenically unsaturated carboxylic acid alkyl ester monomers include methyl acrylate, methyl methacrylate, ethyl acrylate, ethyl methacrylate, butyl acrylate, 2-ethylhexyl acrylate, glycidyl methacrylate, dimethyl fumarate, diethyl fumarate, dimethyl maleate, diethyl maleate,
Dimethyl itaconate, monomethyl fumarate, monoethyl fumarate, and the like. As a monomer containing a hydroxyalkyl group, β-
Hydroxyethyl acrylate, β-hydroxyethyl methacrylate, hydroxypropyl acrylate, hydroxypropyl methacrylate,
Hydroxybutyl acrylate, hydroxybutyl methacrylate, 3-chloro-2-hydroxybutyl methacrylate, di-(ethylene glycol) maleate, di-(ethylene glycol) itaconate, 2-hydroxyethyl maleate,
Examples include bis(2-hydroxyethyl) maleate and 2-hydroxyethyl fumarate. Examples of vinyl cyanide monomers include acrylonitrile and methacrylonitrile. Examples of the amide monomer of unsaturated carboxylic acid include acrylamide, methacrylamide, and the like. The monomer polymerized in the first stage is used in an amount of 45 to 99 parts by weight of the total, but if it is less than 45 parts by weight or exceeds 99 parts by weight, the adhesiveness decreases. In the first stage polymerization, it is preferable to use the entire amount of the conjugated diene monomer and unsaturated carboxylic acid monomer from the viewpoint of water resistance and adhesiveness. The emulsion polymerization in the second stage is carried out in the presence of the copolymer obtained in the first stage, but when the polymerization conversion rate in the first stage is 70
% or more; if it is less than 70%, it will not be possible to obtain adhesive strength sufficient to withstand high-speed printing. Among the alkali-soluble copolymers used in (B), the vinyl acetate monomer is used in an amount of 0 to 40 parts by weight, but if it exceeds 40 parts by weight, the water resistance of the coated paper decreases. The unsaturated carboxylic acid monomer is used in an amount of 10 to 40 parts by weight, but if it is less than 10 parts by weight, the alkali thickening property will be low, and if it exceeds 40 parts by weight, the viscosity will become too high. Unsaturated carboxylic acid alkyl ester monomer is 10
It is used in an amount of up to 70 parts by weight, but if it is less than 10 parts by weight, the stability will be poor, and if it exceeds 70 parts by weight, the thickening properties will be poor. The vinyl cyanide monomer is used in an amount of 1 to 25 parts by weight, but if it is less than 1 part by weight, the gloss of the coated paper will be poor, and if it exceeds 25 parts by weight, the water resistance will be poor. The amide monomer of unsaturated carboxylic acid is used in an amount of 0 to 10 parts by weight, but if it exceeds 10 parts by weight, the viscosity becomes too high. Monomers containing hydroxyalkyl groups are 0.5
It is used in an amount of ~10 parts by weight, but if it is less than 0.5 parts by weight, the stability is poor, and if it exceeds 10 parts by weight, the viscosity becomes high. The copolymer latex (A) is used in an amount of 99 to 75% by weight (solid content), but if it exceeds 99% by weight, the viscosity will be poor and the gloss will be poor. If it is less than 75% by weight, the water resistance will be poor and the viscosity will become too high, which is not preferable. The copolymer (B) is used at 1 to 25% by weight,
These polymers do not all need to be alkali soluble. The copolymer latex is polymerized in both the first stage and the second stage by a known batch, division, continuous addition polymerization method, or the like. Further, during polymerization, known emulsifiers, polymerization initiators, chain transfer agents, etc. are used. Examples of emulsifiers include anionic surfactants such as higher alcohol sulfate esters, alkylbenzene sulfonates, and aliphatic sulfonates, and nonionic surfactants such as polyethylene glycol alkyl ester, alkyl phenyl ether, and alkyl ether types. are used singly or in combination of two or more. When considering the water resistance of the obtained copolymer latex, it is preferable to use 2 parts by weight or less based on 100 parts by weight of the total monomers in the first and second stages. Examples of initiators include water-soluble initiators such as potassium persulfate, ammonium persulfate, and sodium persulfate;
Alternatively, a redox initiator or an oil-soluble initiator such as benzoyl peroxide can be used. As the chain transfer agent, mercaptans, halogenated hydrocarbons, etc. can be used. The paper coating composition of the present invention is used in a proportion of 99 to 70% by weight of pigment to 1 to 30% by weight (solid content) of binder. Outside these ranges, the purpose of the present invention will not be achieved. The pigment is not particularly limited, but heavy calcium carbonate, light calcium carbonate, clay, barium sulfate, kaolin, aluminum hydroxide, satin white, titanium dioxide, calcium sulfite, zinc sulfate, plastic pigments, and the like can be used. Examples are shown below, but the present invention is not limited by the examples. Example 1 Production of copolymer latex (A). Each monomer and emulsifier used in the first stage shown in Table 1 1.2 parts by weight, ammonium persulfate 0.8 parts by weight,
A mixture of 0.5 parts by weight of tertiary dodecyl mercaptan and 100 parts by weight of water was charged into 10 autoclaves and polymerized at 65°C with stirring.
Polymerization was completed by additionally adding each monomer shown in the table. Table 1 shows the polymerization conversion rate when the second stage monomer addition started. The polymerization conversion rate of the obtained latex was 99% in all cases.
That's all. After removing unreacted monomers from these latexes by stripping, the latexes were passed through a 200-mesh wire gauze to obtain a copolymer latex (A).
