For example, Japanese Patent Publication No. 49-40656 discloses a clay made of wheat flour or the like as a main raw material containing synthetic latex for the purpose of rapidly drying and solidifying a formed plastic image. However,
Although this clay for work is excellent in quick-drying, it is difficult to handle because it may dry and harden during the production of the work. Also, since a vinyl acetate resin is used as a solidifying agent, it has a unique odor.

In Japanese Patent No. 29880, corn starch is used as a main component,
A craft clay composition comprising a vinyl acetate resin emulsion as a solidifying agent is disclosed. The clays described in these publications also have a unique odor because they contain a vinyl acetate resin.

In order to avoid such a problem, Japanese Patent Application Laid-Open No.
It is not preferable to use a vinyl acetate resin as a solidifying agent, as in the invention disclosed in JP-A Nos. 61-29880 and 61-29880, since a peculiar smell is imparted to the clay.

せた。The present inventors have conducted various studies in order to solve the above-mentioned problems of the prior art. As a result, the gums and the pregelatinized flour and / or pre-gelatinized flour are contained at a fixed ratio with respect to the starch as a main component. By blending with pregelatinized starch, it is possible to maintain the appropriate shape retention, plasticity, and storage stability of clay without blending a solidifying agent such as vinyl acetate resin and without a heating step. It has been found that a clay having a low drying rate and easy handling can be produced, and the present invention has been completed.

Starches have strong dilatancy and lack clay-like shape retention and plasticity, and the effects obtained by using starches and gums together cannot be expected. In addition, the compounding amount of gums is 20
When the amount is more than the weight part, the spinnability of the gums comes out, and the shape retention and the plasticity are also lacked. When the amount of the pregelatinized flour or pregelatinized starch is less than 1 part by weight, the strength when the clay is dried is lacking, which is not preferable. It becomes lacking in sex. If you make clay with only gums and starch without adding pregelatinized flour or pregelatinized starch,
Fragile when dry and lacks strength. In addition, if clay is made only from pregelatinized flour or pregelatinized starch and starch, the storage stability in a non-dried state is poor, and pregelatinized flour or pregelatinized starch ages.
The clay becomes ragged and sticky.
