laminated sheet consisting of a plural number of sheets selected ~rom the group oE said sheets. In cases where said masking member is made of a sheet from plastics or rubber, it is desirable to mix inorganic filler such as calcium carbonate, silica, talc, clayr bentonite, stone powder, blast furnace slag, flyash, and the like into said plastics or rubber since heat resistance, mechanical properties and the like of said masking member are improved ~, . .. :
: . , . ~ - :
3 ~:
by said inorganic filler and further, when a used masking member is burnt in a combustion furnace, a smaller combustion energy is produced so that said combustion furnace will stand long use. Usually, 10 to 500 weight parts, desirably 20 to 400 weight parts of said inorganic filler are mixed into said plastics. Further organic filler such as wood powder, organic, fiber powder, walnut powder, coconut powder, flour, chaff powder and the like may be mixed into said plastics or rubber. Still further, dyestuff, pigment, antioxidant~ ultra~iolet absorber plasticizer and the like may be mixed into said plastics or rubber. Polyolefin such as polyethylene, polypropylene and the like are desirable plastics for the material of the sheet of the masking member of the present invention since said polyolefin has high solvent resistance and is inexpensive, and of course, polyolefin in which said inorganic filler is mixed is a desirable material for said masking member. Polystyrene foam is also a desirable mater:Lal for said masking member since said polystyrene foam is light and inex~ensive, nevertheless, since said polystyrene foam has a low solvent resistance and a low heat resi3tance, it is desirable to laminate a suitable plastic or rubber onto said polystyrene foam.
,~ ' ~- Vacuum forming, press molding, casting, extrusion, injection, molding, paper making and the like may be used to produce the masking member of the present invention.

~he masking member of the present invention is easily attached to a part of a surface of an article to be protected by inserting (a~ pro;ection(s) of said part into (an~ indention(s) of the masking member and said masking member is easily removed from said part by extracting said projectionts) of said part from said indention(s) of said masking member. Accordingly, said masking member of the 2Q~3~
present invention can be correctly, easily, and securely attached to a part of a surface by the guide of said projection(s) of said part and said indention(s) of said masking memher.
Fig. 1 to Fig. 4 relate to an embodiment of the present invention. Referring now to Fig. 1 to Fig. 4, a masking member (110) is produced by the molding of a sheet (111) and has a shape corresponding with the surface of the lower half (121) of a bumper (120) of an automobile (130) and indentions (111A), (111B) are formed in both ends of said mas}cing member ~110) wherein projections (121A), (121B) in both ends of said lower half t121) of said bumper (120t are insexted into said indentions ( 1 1 1 A ), ( l l l B ) of said masking member (110). Further/ a reinforcing rib (113) is formed in said masking member (110) and an adhesive layer (112) is formed on the upper edge of the inside of said masking member (110).
Said masking member (110) is correctly, easily, and securely attached on said lower half (121) of said bumper (120) by inserting said projections (121A), (121B) of said bumper (120) into said indentions (111A), (111B) of said masking member (110) and adhering said adhesive layer (112) to the upper edge of said lower half (121) of said bumper (120), and then a paint (140) is coated on said bumper (120) as shown in Fig. 3. After said coating, said masking member (110) is easily removed from said bumper (120) and said paint (140) is not coated on said lower half ~121) of said bumper (120) while said paint (140) is coated on the upper half (122) of said bumper (120) as shown in Fig. 4.
Fig. S and Fig. 6 relate to another embodiment of the present invention. Referring now to Fig. 5 and Fig. 6, 2~0~3~
a masking member (150) is produced by the molding of a sheet (151) and has a shape corresponding with a part (161) of the surface of the underside of an automobilel and a pair of indentions (151A), (151B) are formed in said masking member (150) wherein projections (161A), (161B) of said underside of said automobile are inserted into said indentions (151A), (151B) of said masking member (150).
Said masking member (150) is attached on said part (161) of said surface (160) of said underside of said automobile by inserting said projections (161A), (161B) of said part (161) o~ said surface (160) of the said underside of said automobile into said indentions (151A), (151B) of said masking member. In a case that the minimum diameters of said indentions (151A), (151B) of the masking member (150) are respectively a little smaller than the maximum diameters of said projections t161A), (161B) of said part (161), said projections (161A), (161B) are tightly inserted into said indentions (151A), (151B) and as the result, said masking member is securely attached to said part (161) without an adhesive layer. In this case, it is desirable that a laminated sheet consisting of a. soft elastic sheet such as a soft-type polyvinylchloride foam sheet, soft-type polyurethane foam sheet, soft-type melamine resin foam sheet, foam rubber sheet, felt sheet and the like, and a rigid sheet such as a hard-type polyvinylchloride sheet, polys~yrene sheet, polyethylene sheet, polypropylene sheet, resin-impregnated fiber sheet, hard-type paper, hard-t~pe wooden shèet, metal sheet and the like is used as the material of said masking member ~150). In said masking member ~150), said soft elastic sheet is located inside said indentions (lSlA), (151B) and said rigid sheet is located outside said indentions (151A), (151BJ. Said surface (16Q) of said underside of said automobile is then coated with a paint. After said coating, said masking member (150) is removed from said part (161) of said surface (160).
by said inorganic filler and further, when a used masking member is burnt in a combustion furnace, a smaller combustion energy is produced so that said combustion furnace will stand long use. Usually, 10 to 500 weight parts, desirably 20 to 400 weight parts of said inorganic filler are mixed into said plastics. Further organic filler such as wood powder, organic, fiber powder, walnut powder, coconut powder, flour, chaff powder and the like may be mixed into said plastics or rubber. Still further, dyestuff, pigment, antioxidant~ ultra~iolet absorber plasticizer and the like may be mixed into said plastics or rubber. Polyolefin such as polyethylene, polypropylene and the like are desirable plastics for the material of the sheet of the masking member of the present invention since said polyolefin has high solvent resistance and is inexpensive, and of course, polyolefin in which said inorganic filler is mixed is a desirable material for said masking member. Polystyrene foam is also a desirable mater:Lal for said masking member since said polystyrene foam is light and inex~ensive, nevertheless, since said polystyrene foam has a low solvent resistance and a low heat resi3tance, it is desirable to laminate a suitable plastic or rubber onto said polystyrene foam.
