場合もある。Another possibility is to coat or impregnate the composition and dry it, then apply a layer of white paint or the like to hide the discoloration. It is not practical because the top coat layer tends to fall off due to insufficient amount, and furthermore, the above-mentioned publication regarding the composition states that discoloration over time can be reduced by incorporating an appropriate amount of thiosulfate or dithionite into the composition. There is also a description of
Depending on the type of support, little effect may be expected.

付与が困難となり、実用的でない。In the above aqueous composition, the content of the dialdehyde compound is preferably 1 to 4000% by weight (in terms of solid content; the same applies hereinafter) based on the total amount of L-ascorbic acid and iron (I[) compound used. It is important that the weight be ~400% weighted. When the amount used is less than 1% by weight, the effect of reducing discoloration over time when a support is coated or impregnated with the obtained aqueous composition becomes insufficient. In addition, if the amount used exceeds the upper limit of 4000% by weight, the above-mentioned drawbacks will be resolved, but if the concentration of the two-component composition (mixture containing L-ascorbic acid + iron (II) compound) is too low, it will have sterilizing and deodorizing properties. This makes it difficult to apply and is not practical.

It is important that the This range is the best range for imparting the desired bactericidal and deodorizing properties to the support after coating or impregnation. If this content is less than 0.1% by weight, the desired sterilization and
In addition, if the content exceeds 30% by weight, the above drawbacks will be resolved, but it will be difficult to maintain the specified concentration (0.3 to 50% by weight) of the water-based composition, and the coating will become difficult. It is inappropriate to include such processing.

Moreover, conventionally, L-ascorbic acid and iron (
II) The deodorizing property of the composition containing the compound is very good against nitrogen-based malodors (components) such as ammonia and amines, but on the other hand, it is extremely effective against nitrogen-based malodors (components) such as hydrogen sulfide and mercaptans. However, the aqueous composition of the present invention contains a dialdehyde compound, Among these compounds, glyoxal and the like have deodorizing properties themselves, and the deodorizing effect is due to the composition containing L-ascorbic acid and iron (II) compound for nitrogen-based malodors (components) such as ammonia and amines. Although it is not as bad as the odors of sulfur-based odor (components) such as hydrogen sulfide and mercaptan, the above-mentioned L-ascorbic acid and iron (

。! Table 3 As is clear from Table 3, an aqueous solution containing L-ascorbic acid and ferrous sulfate and a composition (aqueous solution) in which glyoxal was mixed with this aqueous solution were applied in a coating amount (L-ascorbic acid and ferrous sulfate). When the coated paper is coated on a support (Gi) so that the total solid content of iron is the same and is treated in an odor-containing atmosphere by a prescribed method, the deodorization rate is the same for ammonia for both solutions. shows a high deodorization rate,
Regarding hydrogen sulfide, the solution containing glyoxal showed a significantly higher deodorization rate than the solution containing no glyoxal. In other words, by using glyoxal in combination, the original bactericidal and deodorizing effects of L-ascorbic acid and iron (II) compounds are not inhibited in any way, and the imbalance in deodorizing power with respect to the type of malodorous components is corrected and balanced. It can be seen that the deodorizing properties are improved. Furthermore, even when a vegetable gum substance is mixed, the effect of glyoxal is not inhibited in any way.
