Transparent paper has traditionally been made of untreated, translucent paper such as glassine paper, as well as paper made of wax, polyester resin, etc.
It is manufactured by coating paper with an organic clarifying agent such as the glycerin ether of polypropylene glycol. However, transparent papers coated with these transparentizing agents usually have the disadvantage of becoming sticky or blocking during use or storage due to the low heat resistance of the transparentizing agent. Furthermore, when these papers are used as copying paper for copying machines such as Xerox, they have the disadvantage that they tend to burn in some areas during copying and cause odor. Furthermore, when printing is applied to these transparent papers, there are defects in that the adhesion of printing ink is inhibited and the ink changes color due to migration of the transparentizing agent. Therefore, although various proposals have been made to improve these deficiencies, the current situation is that no effective method has yet been found to improve all of these deficiencies.

In the present invention, the above-mentioned metal alkoxide is used alone or dissolved or dispersed in a solvent such as alcohol such as methanol, ethanol, isopropyl alcohol, etc., and this is coated or impregnated on paper by a conventional method (hereinafter referred to as coating). After that, the coated paper is heated. Although the details of the reaction are unknown, the above treatment transforms the metal alkoxide into metal oxides through hydrolysis and dehydration reactions, and at the same time makes the paper transparent, gives it dimensional stability, and prevents the paper from curling. It is presumed that it imparts various properties to paper, such as: Incidentally, in the metal alkoxide treatment, a reaction accelerator can be added to the metal alkoxide.

Various papers can be used as the paper treated with metal alkoxide in the present invention. For example, to obtain paper with excellent transparency, use paper with an ill content of 0 to 5%.
It is particularly desirable to use paper that does not contain opaque fillers. Examples of such paper include glassine paper, manuscript paper for copying, packaging paper such as pure white roll paper, non-pigment coated printing paper, imitation paper, and Japanese paper. On the other hand, in the present invention, in order to impart some transparency or to impart dimensional stability and curl resistance even to opaque paper, a larger amount of filler than the above filler content is added. Paper that contains metal alkoxides is also subject to metal alkoxide treatment. In addition to the above-mentioned papers, paper used in such cases includes continuous slip paper, high-quality paper, pigment-coated paper, india paper, laminated paper, and metal-metalized paper. Further, in addition to the above-mentioned paper qualities, the present invention targets papers of various basis weights, but generally those with a basis weight of 20 to 150 g/m' are used. Ru.

The results are summarized in Figures 1 and 2. It is clear from FIG. 1 that as the coating amount of tetrapropoxysilane increases, the transparency improves, and this effect is particularly noticeable in papers with good impregnation properties, such as pure white rolls. Moreover, from FIG. 2, it can be seen that as the coating amount of tetrapropoxine run increases, the elongation of the paper becomes smaller, and a remarkable dimensional stabilization effect can be obtained even in paper such as glassine paper, which is particularly easy to elongate. Furthermore, the curl after coating became smoother and smaller as well as the water immersion elongation improved.
