Description

[Detailed explanation of the invention] The number of people who love shogi is on the rise, and there are many books out there that explain this.

A common drawback of these books is that they are written in such a way that the correct answer to the next move jumps out at you even when you don't want to see it.

This hinders their efforts to think of their next move on their own.

The present invention was developed in view of this point, and the Iki Shogi practice book according to the present invention is designed to:
JL, 0 One move or several moves to be made are directly printed using a recording material containing an amine salt of molybdate, or another pre-printed synthetic resin film is pasted thereon.

Already, in Utility Model Publication No. 43-17123, letters (or designs) were printed using water-repellent ink, and then plain mesh printing was applied to cover the text using ink that develops color when the dye is eluted by water.
A printed matter in which characters and the like appear with water is disclosed, which is characterized in that parts other than the water-repellent ink are colored by applying water and rubbing.

However, the special ink used here is an ink that elutes dye and develops color when rubbed with water, and therefore has the disadvantage that the printed matter can only be used once.

Furthermore, since it cannot be produced by lithographic offset printing, which uses water in the printing process, it is not suitable for mass printing on poor quality paper such as washed paper.

In contrast, the present invention uses molybdate amine salt as a recording material, and examples of the molybdate amine salt include trimolybdate dimethylamine salt, molybdate di-n-butylamine salt, and the like.

These compounds reversibly absorb in the visible region when exposed to light or other radiation, and for example, among the above-mentioned compounds, those printed using a recording material containing trimolybdate dimethylanate While shielded, it is colorless, but when exposed to light, it eventually turns red and colored.

If it is then shielded from light, it immediately returns to its colorless state.

The present invention uses such recording materials to provide a unique Iki shogi practice book as described below.

The Iki Shogi practice book of the present invention shows a scene in progress of Iki or Shogi on the same page or the same side of the practice book, for example, on both pages when the practice book is opened, with a given move or number. The hand is printed with a conventional printing ink, and the move or moves to be struck next are printed with a recording material containing the molybdate amine salt described above.

Printing with this conventional printing ink pattern and the recording material can generally be carried out on the same drawing of the substrate or the chess board.

However, the drawings are not limited to this, and may be separate drawings.

It is preferable that such a drawing of the ongoing board or chess board be printed at the beginning of the page that is opened and exposed to light, taking into account the relationship with the problem and explanatory text.

According to the printed Shogi or Shogi practice book of the present invention, one reads the explanations and problems before or while looking at the drawing in progress, and from a given move or several moves of the drawing exposed to light. You can think about the next move or several moves, and then see the next move or several moves printed in color to find out the correct answer.

Alternatively, the next move or several moves may be printed on a transparent synthetic resin film, and one end of this may be pasted so as to overlap the board or shogi board image on which the given move or moves are printed.

In such practice books, if the next move or moves printed on the synthetic resin film start to color before you can think of the next move or several moves, you can fold the synthetic resin film back and print the next move. This is useful in that you can avoid knowing one or more moves.

Methods for printing recording materials containing molybdate amine salts include vapor deposition, coating a solvent dissolved or dispersed in water or other solvent, and drying.In this case, a resin is added as a dispersion medium to the solution. There are ways to add it.

According to the Iki Shogi practice book of this invention, you can always think of your next move with fresh thinking and without any preconceptions.
The results of practice are great, and you can quickly acquire the ability to play chess and shogi.
