Are sequentially provided, and these are integrated print sheets for cleaning graffiti (claim 1).

In the present invention, a printing layer is formed on the surface of a base film, and a transparent film and a silicone resin layer are sequentially provided thereon. Therefore, the printing layer is protected by the transparent film and the silicone resin layer, and the printing layer is not directly stained by graffiti paint or the like. Also,
Since the surface of the graffiti-cleaning printed sheet is covered with the silicone resin layer, graffiti is performed on the silicone resin layer. The graffiti written on the silicone resin layer can be easily erased by wiping the surface of the silicone resin layer with a petroleum-based cleaning solution or the like, and the surface of the graffiti cleaning printed sheet can be easily cleaned. it can.

Therefore, according to the present invention, it is possible to provide a graffiti-cleaning printed sheet that can easily clean even if graffiti is made.

Next, a second invention is to form a printed layer on which characters, patterns, photographic images, etc. are printed on the surface of a base film, and to form a transparent film and a transparent silicone resin layer on the upper surface of the printed layer. These are made up of an integrated graffiti cleaning printing sheet and an oil-based cleaning liquid for cleaning graffiti written on the surface of the graffiti cleaning printing sheet with paint or the like. This is a graffiti cleaning set that can easily erase characteristic graffiti (claim 3).

[0010] In the present invention, the graffiti-cleaning printing sheet and the petroleum-based cleaning liquid shown in the first invention are used as one set. The printed layer of the graffiti cleaning print sheet is protected from graffiti as shown in the first invention. The graffiti is performed on the outermost silicon resin layer, and the graffiti can be easily cleaned by wiping with the petroleum-based cleaning liquid. Therefore, by setting the graffiti cleaning print sheet and the petroleum-based cleaning liquid as one set, it is possible to easily carry out cleaning measures against graffiti, which is convenient.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the first aspect of the present invention, examples of the base film include a resin film of polyvinyl chloride, polyethylene, polypropylene, olefin or the like. The printing layer is formed on the surface of the base film using an ink, a paint, or the like that can be printed on the base film. The printing layer includes characters, symbols,
There are patterns, paintings, and photographs. The graffiti-cleaning print sheet provided with these print layers is used for any purpose such as advertisement, gazette, catchphrase, company name, and product name.
The graffiti-cleaning printing sheet is used by attaching it to a telephone box, a show window, a shutter, or the like.

As the transparent film, there is, for example, the above resin film. The transparent silicon resin layer is formed by using a resin containing silicon and coating it on the transparent film, or by sticking a silicon resin film on the transparent film. Further, the silicon resin layer only needs to have a degree of transparency that is sufficient to allow the characters and the like of the printing layer to be seen. The base film, the transparent film, and the silicone resin layer are integrated by, for example, using an adhesive or by bonding by heat fusion. In the printing layer, for example, a printing ink or a paint is fixed to the base film to be integrated, or the printing layer may be sandwiched and integrated between the base film and the transparent film.

Next, the base film preferably has an adhesive layer on the back surface. In this case, the graffiti cleaning print sheet can be attached in any case.

Further, in the second invention, the paint is a concept including a paint such as paint and an ink. Examples of the graffiti written with the paint or the like include those written using oil-based ink, oil-based spray, or the like. In particular, the present invention can easily clean the surface of a graffiti-cleaning printing sheet with the above-mentioned petroleum-based cleaning liquid even if the graffiti is written with an oil-based paint such as an oil-based ink or an oil-based spray. It has a great effect on Examples of the petroleum-based cleaning liquid include a thinner and an isoparaffin-based solvent.
