Description of the Related Art Conventionally, in aqueous ink compositions, plate-like pigments such as pearl pigments and aluminum powder pigments have been used as inks for obtaining brilliant handwriting. These plate-like pigments need to be larger than ordinary organic pigments and inorganic pigments in order to reflect light and obtain glitter, and the average particle diameter of the plate-like pigment used is at least 5%.
A size of at least μm is required. When a pigment having such a large particle diameter is used, the sedimentation speed of the particles is high and the pigment and the solvent become non-uniform, that is, color separation easily occurs. It is necessary to obtain a handwriting with a uniform concentration by shaking and moving a ball or stick for ink stirring, which is previously set inside the barrel, to uniformly mix the pigment and the solvent by an external force.

Recovered, when used by filling in a writing instrument, the pigment and the solvent are uniformly mixed by easily moving the ball or stick for ink stirring, and a handwriting with a uniform concentration is easily obtained. Even if it is left standing for a long time, the pigment can be easily redispersed in the ink composition by easily moving the ball or stick for stirring the ink. It is an object of the present invention to provide a brilliant aqueous ink composition which can be prevented from being cured to form a so-called hard cake.

Alternatively, it can be easily recovered by adding thermosetting resin particles, and when used in filling in a writing instrument, the ball and stick for stirring the ink can be easily moved so that the pigment and the solvent can be uniformly mixed. In addition, the present invention has found that a handwriting having a uniform concentration can be easily obtained, and that the pigment can be easily re-dispersed in the ink composition even if left for a long period of time. It has been reached.

Form. This structure has a large area where the pigment is in contact, and therefore a large contact resistance. Further, since the dispersant adsorbed on the pigment is complicatedly entangled with each other, the adhesion between the particles is further strengthened, and the structure is hard, and it is difficult to break the structure with a small external force. However, the thermosetting resin-based emulsion and the thermosetting resin particles used in the glittering aqueous ink composition according to the present invention enter between these plate-like particles to prevent direct contact of the pigment. Further, it is possible to prevent the dispersant adsorbed on the pigment from being complicatedly entangled. Emulsion particles and resin particles entering between the plate-like particles are thermosetting resins that do not melt even in a high-temperature region, so that there is no movement of molecular chains, and an action of not entangled adjacent molecular chains is exhibited. The effect of not forming a layered structure is shown.

る。[Table 1] As described above, the glitter aqueous ink composition according to the present invention,
When left standing for a long period of time, the ink is easily stirred without forming a hard cake, so that color separation can be easily recovered, and the pigment and solvent can be quickly mixed uniformly to obtain a uniform concentration. Handwriting can be easily obtained. Furthermore, since the number of the stirring balls of the writing implement is at least one,
It is an excellent ink composition that is also advantageous for product cost.
