本発明の水性修正液が、何故、実用上十分な隠蔽力があ
りながら、経時的にハードケーキを作らない水性修正液
であるかについては、以下の理由によると推察される。(Function) The reason why the aqueous correction fluid of the present invention is an aqueous correction fluid that does not form a hard cake over time while having a practically sufficient hiding power is presumed to be due to the following reasons.
一般に、顔料などの粉体と樹脂などの結合剤及び溶剤を
主な成分とした顔料分散体において。Generally, in a pigment dispersion whose main components are a powder such as a pigment, a binder such as a resin, and a solvent.
隠蔽力は、顔料濃度が上昇するにつれ増大する。Hiding power increases as pigment concentration increases.
しかしながら、顔料は、ある一定の濃度に達した時、隠
蔽力が逆に減少するという、臨界顔料体積濃度を示す事
が知られている。これは、顔料濃度が上昇するにつれて
粒子の間隔が接近し、その間隔が光の波長の１／２以下
に接近すると、２つ以上の粒子はあたかも１つになった
と同じようになり、隠蔽力は逆に減少する現象である。However, it is known that pigments exhibit a critical pigment volume concentration at which the hiding power decreases when a certain concentration is reached. This is due to the fact that as the pigment concentration increases, the distance between the particles becomes closer, and when the distance approaches 1/2 or less of the wavelength of light, two or more particles become as if they had become one, and the hiding power increases. On the contrary, it is a decreasing phenomenon.

るものと思われる。However, the water-based correction fluid of the present invention has
Since we use a composite pigment attached with silica powder or a mixture of silica powder and aluminum oxide, titanium oxide has a constitution that does not show hiding power when used alone as silica powder or a mixture of silica powder and aluminum oxide. The pigments do not approach closer than a certain distance. For that reason,
There is no critical pigment volume concentration that would lead to a decrease in hiding power, and it appears that there is sufficient hiding power even without using an excessive amount of titanium oxide pigment.
