Description

  The present invention relates to an aqueous paint composition. Specifically, the present invention relates to an aqueous paint composition that has a fluffy feel after drying and is difficult to crack.

  Conventionally, oil-based paints, water-based paints, and the like are known as paints. Oil-based paints have the feature that a three-dimensional finish can be expected by changing the thickness of the coating film in painting and coloring. However, oil-based paints are unsuitable for general use, such as paints that have a unique oily odor, slow drying of the paint film, and unfavorable hygiene pigments depending on the color type. It is not suitable for use by the following children.

  On the other hand, as an aqueous paint, what mix | blended a coloring agent, water-soluble resin, a resin binder etc. is known, for example. Water-based paints are characterized by rapid drying after drawing and easy dilution and washing with water. For example, Patent Document 1 discloses an aqueous paint composition containing a color pigment, a water-soluble resin, a wetting agent, and water, using reduced dextrin as the water-soluble resin.

  In recent years, consumer needs have been diversified, and not only the visual impression when drawing with paints, but also the touch feeling when touched with hands etc. Development is required. However, it is conceivable that conventional water-based paint compositions cannot always sufficiently follow the diversifying consumer demands.
