2. Description of the Related Art Hitherto, a polyfunctional (meth) acrylate such as diethylene glycol dimethacrylate and a polymerizable monomer such as lauryl acrylate have been used in an aromatic hydrocarbon solvent such as an aliphatic hydrocarbon, toluene, benzene, or xylene. A method of producing a copolymer resin dispersion by carrying out a polymerization reaction in the presence of a polymerization initiator is known (JP-A-56-145911, JP-A-56-79112).
issue). However, since the resin dispersion obtained by this production method uses an aromatic hydrocarbon solvent, the crosslinking of the contained resin is easy to proceed, and the resin generated during the progress of the polymerization reaction is gelled or stored. There were problems such as solidification of the resin. In addition, when the non-aqueous resin is used for a paint or an adhesive, the non-aqueous resin is solidified during storage, resulting in a decrease in adhesive strength. So, in order to solve these problems,
2% by weight of polyfunctional acrylate or methacrylate such as polyhydric glycol diacrylate
It was necessary to keep it below. Certainly, the conventional problem can be solved by setting the content to 2% by weight or less, but as a result, the resin becomes soluble in an aromatic solvent, and when used as a paint, the amount of the resin adsorbed on the pigment is reduced. Less, resulting in poor adhesion. In particular, when used as an electrodeposition paint, the pigment is not adsorbed by the resin, which is not desirable as a paint. Furthermore, it has been pointed out that the aromatic solvent used in this method has high toxicity and flammability, and has not only a problem in environmental health, but also a problem of a great risk of fire. The present inventors have developed a method for producing a dispersion comprising a non-aqueous resin in order to solve the above problems. In this method, a polyfunctional acrylic ester or methacrylic ester as described above is mixed with an unsaturated hydrocarbon or a halogenated aliphatic hydrocarbon as a main component in the presence of a polymerization initiator. This is a method in which a polar monomer such as carboxylic acid and a solvable monomer such as lauryl acrylate are subjected to a polymerization reaction with the solvent before and after the polymerization (JP-A-56-79112). However, in this method, the polyfunctional acrylate or methacrylate used as a cross-linking agent has a high cross-linking property, that is, a high cross-linking rate, so that (1) reaction control during polymerization becomes difficult, and In addition to the drawbacks that certain dispersion resins tend to vary, (2) the polymerization is not uniform, only products with a wide particle size distribution can be obtained, and (3) the dispersion stability of the products is poor. Since polyfunctional acrylic acid or methacrylic acid monomer does not have a polar group, (4) the ability to disperse a colorant is low, and even if a monomer having a polar group is used in combination, it has very poor copolymerizability and uniform polymerization. There is a problem that can not be.

In the case of producing a coloring agent, a resin comprising the above-mentioned copolymer is added to a non-aqueous solvent, mixed and stirred, and after a pigment is dispersed, a crosslinking agent is added and heated. Agent is obtained. If a crosslinking agent is not used, the bonding force between the pigment and the resin is weak, the pigment and the resin are easily separated, not only the fixability and dispersibility are deteriorated, but also the life of the developer is shortened. The type of the crosslinking agent is the same as in the case of producing the non-aqueous resin dispersion. Pigments are used to specify the color of the colorant. Examples of the pigment include carbon black, phthalocyanine blue, disazo yellow, carmine 6B, and quinacridone. This colorant can be used for a developer for electrophotography, a paint, a printing ink, and an ink for inkjet.

Example 9 10 g of carbon black (carbon MA100 manufactured by Mitsubishi Chemical) and 100 g of toluene were added to 100 g of the resin of Example 4.
Was added and dispersed with an attritor to obtain a paint. The particle size of the paint was 0.2 μm, and the adhesion and gloss of the coating film were good.

Example 10 When the liquid toner of Example 7 was used for an ink jet ink, the image density was 1.44, the ejection property was 25 μm dots, and the light fastness was one year or more. On the other hand, the results of the conventional inkjet ink (ink for Mach Jet manufactured by Seiko Epson Corporation) were 1.22 in image density, 80 μm dots in ejection property, and 1 month or less in light fastness.

The electrophotographic liquid developer and the electrophotographic dry developer using the resin dispersion or the colorant according to the present invention are excellent in image density, resolution, electrodeposition and durability. Further, the occurrence of offset in the heat roller fixing is small. In addition, when used in paints, printing inks, and inks for ink jets, it is possible to obtain results with high image density and good resolution, fixability, gloss, ink ejection properties, and light fastness.
