2. Description of the Related Art In artificial laminated lumber such as kotatsu top plates, furniture wall materials such as chests of drawers, ceiling materials, and pillars, titanium paper with a wood grain pattern or titanium paper with black solid printing is adhered to the surface of plywood. Using a printed plywood laminated with a chemical, cut this, cut with a saw, etc., perform secondary processing such as fitting, needle punching, etc., and attach a butterfly board, handle, edge material, etc. if necessary I am trying.

However, in handling the printed plywood, in order to prevent scratches on the surface of the printed plywood, the printed plywood maker should be placed between the printed plywood when it is transported to a furniture maker or a construction shop. Insert thin paper into the
Every 10 or 10 sheets are shipped in polyethylene bags. Further, a furniture manufacturer or a carpenter, prior to processing, pulls out the polyethylene bag, then removes the thin paper, takes out the printed plywood, and be careful not to damage the surface of the printed plywood. It is processed into a product, which is reinserted into a polyethylene bag and shipped to a furniture store, or a carpenter has incorporated it into a building structure as a member such as a ceiling or wall material. In such a printed plywood, it takes time and effort to insert and remove a thin paper for protecting the printed plywood, wrap it with a polyethylene bag, and remove the bag. In the secondary processing, furniture furniture
Car and carpenter's attention is a great mental and labor burden to prevent injury.

On the other hand, a video apparatus, a housing of a stereo set, a printed steel plate enclosure placed at the boundary between a civil engineering site and a sidewalk, may or may not contain an inorganic filler in order to prevent scratches during transportation. Acrylic resin type,
A resin film coated with a petroleum resin-based or rubber-based pressure-sensitive adhesive is bonded to protect the coated steel sheet, and secondary processing such as bending, perforation, and cutting is performed with this adhesive protective film bonded. , It is shipped to electronics stores or civil engineering sites. Consumers who have purchased a video device and stereo set from an electronic store remove the adhesive protective film at home and install the device. In addition, at the civil engineering site, the adhesive protective film is peeled off after the enclosure is laid at the boundary.

The method using this adhesive protective film is as follows:
There is an advantage that work can be performed without worrying about scratches on the product during secondary processing or laying. However, the pressure-sensitive adhesive partially adheres to the product (peeling strength is 150 to 300 g / 15
(mm 2) It often remains as it is, and there are many cases where dust adheres and becomes dirty, so it is necessary to wipe off the pressure sensitive adhesive remaining from the product surface after peeling off the adhesive protective film Becomes

[0006]
