Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for cleaning stains on a picture screen and a treatment agent used therefor.

[0002]

2. Description of the Related Art For cleaning, which is the main problem of painting restoration, there is a method (water-based method) in which stains are absorbed on paper by watering washi on the soiled area, and fine dust eraser is used to remove dust with a brush. There is a method (a dry method) in which dirt is adsorbed by stroking it on a spot where dirt such as soot is smeared. The cleaning procedure is basically to remove only stains and not to remove anything other than stains, and if there is a risk of damaging the screen, such as bleeding or peeling off the colors, avoid the measures. There is a need. Although the conventional cleaning method can deal with many stain cases, wetting on the colored screen such as Japanese painting and stains from the base material, etc.
Regarding local stains on the picture screen, it is difficult to adopt the conventional wet method because it affects sound areas, and it is impossible to clean the stain itself with the dry method. Can not.

DISCLOSURE OF INVENTION Problems to be Solved by the Invention According to the present invention, stains locally generated on the screen of a painting, such as water wetting on a colored screen such as a Japanese painting and a stain on the base material, can be eliminated on the screen. It is an object of the present invention to provide a method for cleaning without affecting the location and a treatment agent used therefor.

[0004]

[Means for Solving the Problems] In order to clean a stain locally generated on a screen of a painting without affecting a portion other than a stain portion, a treatment agent is applied only to the stain portion, and the applied treatment agent is applied. It is necessary that the fluid does not flow and stays in the damaged area. The present inventor, as a result of studying a treatment agent that enables such treatment, dissolves ammonium hydrogen carbonate as a cleaning solvent in hydroxypropyl cellulose or an aqueous solution thereof used for adjusting the viscosity of the cleaning agent and the like. It was found that the above treatment agents satisfy the above properties as a treatment agent having a certain viscosity. The proportion of ammonium hydrogen carbonate dissolved in hydroxy propyl cellulose or its aqueous solution varies depending on the use conditions such as the material of the painting to be cleaned and the properties of the Japanese paper used for the cleaning procedure. It is preferable to use 1 to 10 g of ammonium hydrogen carbonate with respect to 100 g of a 5 to 30% aqueous solution of cellulose, and more preferably 4 g of ammonium hydrogen carbonate to 100 g of a 10% aqueous solution of hydroxypropyl cellulose. It is a ratio.

In order to remove only stains without affecting other spots on the picture screen, a treatment agent having viscosity is used and the treatment agent stays at the stain spots, and the stain spots on the paint screen are colored. It is necessary to be able to remove the treatment agent without affecting it. As a result of studying a method that enables such cleaning, the present inventor has found the following cleaning method. That is, 1) Washi paper is applied to the stained portion of the painting screen, and a viscous cleaning treatment agent is applied onto the Japanese paper. This treatment agent remains in the jelly-like viscous state and does not drip on the applied portion. 2) Remove the treatment agent together with the Japanese paper applied to the damaged part. In addition,
If there is a part where the paint is peeled off at the dirty portion of the painting screen, it is preferable to perform a cleaning treatment after performing a peeling-off prevention treatment with glue. As a technique related to the anti-stripping treatment, Japanese Patent Laid-Open No. 2000-2893 is available.
There are 96. The treatment agent used in such a cleaning method may be any agent as long as it has viscosity, but is preferably the treatment agent according to any one of claims 1 to 9, and in that case, the cleaning treatment is performed. It is desirable to repeatedly remove the stain several times while checking the condition after cleaning, not to remove the stain at once.
Hydroxy-propyl-cellulose 10% aqueous solution 100
The treatment time when using a treatment agent in which ammonium hydrogencarbonate is dissolved in a ratio of 4 g per g varies depending on the degree of stain and the condition of the treatment site, but the stain can be absorbed in 2 to 6 minutes. Moreover, any Japanese paper may be used for cleaning, but in consideration of the permeability and the degree of influence on the picture screen, the Japanese paper is preferable. If there is a treatment agent that has passed through the washi paper and is attached to the screen, the treatment agent is wiped with water to remove, and then naturally dried. At that time, if an aqueous solution of ammonium hydrogen carbonate is used instead of water, the cleaning effect is enhanced, and it is more preferable to use an aqueous solution of 2 to 4% ammonium hydrogen carbonate. INDUSTRIAL APPLICABILITY The present invention is particularly effective for cleaning stains that are easily dissolved by water, and can be applied not only to board paintings and Japanese paintings but also to oriental paintings and watercolor paintings.

[0006]

[Example] The painting to be implemented is a technique of glue painting on a board.
It was a Sugito-e painting made with painting materials, with streaky dark brown stains on the design, and the paint on the surface layer was washed off as if the color had been washed. Regarding this painting, first, the periphery of the stained portion and the portion where the paint was peeled off at the stained portion were treated with glue to prevent the paint from falling off. Next, a stain sticking paper (ultra-thin Japanese paper) was applied to the soiled portion, and a treatment agent in which ammonium hydrogencarbonate was dissolved in a ratio of 4 g per 100 g of a 10% aqueous solution of hydroxypropyl cellulose was applied thereto. This treatment agent remains in the jelly-like viscous state and does not drip on the applied portion. Further, the hydroxypropyl cellulose aqueous solution absorbs the dirt dissolved by ammonium bicarbonate, which is a weak alkali. Six minutes later, the stain-absorbing and brown treatment agent was removed together with the standard tool paper applied to the spot of stain, and the treatment agent that had passed through the standard material paper and adhered to the screen was wiped with an aqueous solution of ammonium hydrogen carbonate. Removed and air dried. In this example, this process was repeated three times to remove streaky stains on the target painting.

[0007]

According to the present invention, stains locally generated on the screen of a painting can be cleaned without affecting other places on the screen.
