Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a resin composition for a pigment masterbatch. More specifically, the pigment dispersibility is good, and the room temperature dry type alkyd, alkyd melamine,
The present invention relates to a resin composition suitable for producing a pigment masterbatch for paints applicable to a very wide range of paint resins such as acrylic lacquer, acrylic melamine, acrylic urethane, vinyl acetate-acrylic, and nitrified cotton lacquer.

[0002]

2. Description of the Related Art Conventionally, a paint containing a pigment is prepared by mixing a pigment and a dispersing resin to prepare a pigment dispersion for a primary color paint (pigment masterbatch), and then using the same resin as that used for the dispersion. It is diluted and commercialized. This is because when the pigment dispersion resin used for each pigment masterbatch and the resin used for dilution are different from each other, the compatibility between the resins is generally poor, and there is a problem such as a decrease in gloss and hardness of the coating surface. This is because it occurs, and has excellent compatibility with many types of paint resins,
It has been desired to develop a pigment-dispersing resin that can be commonly used in various resin paints. For this purpose, a method of using a urethane-modified polyester resin as a resin for dispersing a pigment (Japanese Patent Laid-Open No.
91115), a method of using a copolymer of butyl acrylate and a specific nitrogen-containing monomer as a resin for dispersing pigments (JP-A-60-139713), and the like.

[0003]

However, in the above method, the urethane-modified polyester resin has compatibility with a relatively wide range of resins, but since it has a urethane bond, its weather resistance is insufficient. There is a problem that it cannot be used for paints that require weather resistance (exterior paints, etc.), and the copolymers of butyl acrylate and specific nitrogen-containing monomers are limited in the types of compatible resins. Therefore, there is a problem that it cannot be used for a wide range of paints.
