管表面保護フイルムが知られている。The pressure-sensitive adhesive layer of the surface protective film temporarily attached to the surface-treated cathode ray tube causes a chemical reaction by contacting with the chemical agent forming the coating film of the cathode ray tube.
There has been a problem that the adhesive component remains in the concave portion of the rough surface and remains after the surface protective film is peeled off, resulting in stains such as adhesive residue and fogging. As a solution to the above-mentioned problems, a cathode ray tube surface protection film described in JP-A-5-339544 is known.

にして仮着することが出来るものである。The cathode ray tube surface protective film described in the above publication is formed on one side of a thermoplastic resin film or sheet,
Since the pressure-sensitive adhesive layer is formed only on at least one of both ends, the pressure-sensitive adhesive layer can be temporarily attached so as not to contact the front surface of the cathode ray tube.

業の際に外観不良や作業性の低下を招くことがある。The surface protective film is manufactured as a long product and wound into a roll to obtain a product. Therefore, as described in the above publication, the thermoplastic resin film provided with the pressure-sensitive adhesive layer at both end portions has a difference in thickness between the pressure-sensitive adhesive-coated portion and the non-coated portion when it is wound in a roll, The part has a thick roll shape and the appearance is poor.
In addition, a wrinkle may be generated in the non-coated portion, or blocking may occur in the non-coated portion due to the winding pressure, which may lead to poor appearance and poor workability when the cathode ray tube is attached.

特徴とするものである。A pressure-sensitive adhesive tape for protecting a cathode ray tube according to the present invention comprises a non-woven fabric having a thermoplastic resin layer laminated on one side thereof and the other end of the non-woven fabric impregnated with the pressure-sensitive adhesive. The thickness of the non-woven fabric in the portion impregnated with is equal to the thickness of the non-woven fabric in the non-impregnated portion of the adhesive.

Those that have been applied are preferred. When the number of fibers arranged in the non-woven fabric is less than 1 in the lengthwise direction with respect to 1 in the widthwise direction, the elongation in the lengthwise direction becomes too large when used as an adhesive tape, resulting in poor workability in pasting. If it becomes too large, the elongation in the longitudinal direction becomes too small, and the stress of the base material is not sufficiently relaxed at the time of peeling, resulting in fracture. Therefore, the fibers are preferably arranged in a length: width ratio of 1: 1 to 8: 1.

れる。As a raw material for the thermoplastic resin layer laminated on one surface of the non-woven fabric, the plasticizer containing soft polyvinyl chloride may exude to the surface and contaminate the surface of the cathode ray tube. Therefore, polyolefin such as polyethylene or polypropylene is used. Resins and polyethylene terephthalate are preferably used.

悪く、３０μｍを超えると手切れ性が悪くなる。The thickness of the thermoplastic resin layer is 8 to 30 μm.
Is preferred. If it is thinner than 8 μm, the workability is poor because the waist is too weak, and if it is thicker than 30 μm, the hand tearability is poor.

ていることが好ましい。The method for laminating the thermoplastic resin layer on one surface of the non-woven fabric is not particularly limited. For example, a method of adhering it through a molten resin, a method of adhering it with an adhesive, or a method of adhering the thermoplastic resin in a molten state onto the non-woven surface. Examples include a method of extrusion lamination. On the surface of the thermoplastic resin layer laminated on one side of the non-woven fabric,
It is preferable that the rolled material is peeled off so that it can be easily spread.

い。The pressure-sensitive adhesive applied to both ends of the other surface of the non-woven fabric on which the thermoplastic resin layer is laminated is not particularly limited, and rubber type, acrylic type and the like are preferably used. To apply the pressure-sensitive adhesive, it is preferable that the pressure-sensitive adhesive solution dissolved in a solvent is directly applied to the non-woven fabric by an ordinary roll coater or the like and dried.

きる。According to this method, the non-woven fabric is immediately impregnated with the pressure-sensitive adhesive applied in a solution state, and since the non-woven fabric is dried in that state, swelling due to the thickness of the pressure-sensitive adhesive layer hardly appears on the non-woven fabric surface, and the obtained pressure-sensitive adhesive is obtained. A roll having a certain thickness can be obtained even when the tape is wound. Further, since the non-woven fabric is integrated with the non-woven fabric by impregnating the non-woven fabric with the non-woven fabric, the non-woven fabric and the non-woven fabric are not separated from each other when the non-woven fabric is peeled off from the cathode ray tube, and no adhesive residue occurs. . Further, the peeled adhesive tape can be reused.

きである。The pressure-sensitive adhesive is applied only to both ends of the non-woven fabric, and its application width is preferably 5 mm or more. 5m
If it is less than m, the adhesive width with the cathode ray tube is small, so that the adhesive tape may peel off from the cathode ray tube over time. Widening the coating width eliminates the problem of peeling,
If it is made too wide, the adhesive strength with the CRT becomes too strong, and the workability when peeling off the adhesive tape before the CRT is assembled into the frame of the TV deteriorates. Further, if the pressure sensitive adhesive comes to the front surface of the cathode ray tube, the pressure sensitive adhesive may remain on the surface of the cathode ray tube after peeling. Therefore, the range should not reach the front surface of the cathode ray tube.

よい。The mold release treatment is not always necessary for the adhesive having a high cohesive force, for example, an acrylic adhesive having a high cohesive force. You may use the mold release agent normally used in order to make spreading power small, for example, the mold release agent using the long chain alkyl group containing polymer (one company make, brand name "Pyroyl".
Etc.) can be applied in the state of a solvent solution for release treatment. When the pressure-sensitive adhesive tape is wound into a roll, it is sufficient that at least a portion overlapping the pressure-sensitive adhesive is subjected to a release treatment.

一定であり、折れ皺が生じない。In the pressure-sensitive adhesive tape for protecting a cathode ray tube according to the present invention, since the non-woven fabric is almost impregnated with the pressure-sensitive adhesive applied to both end portions of the non-woven fabric, swelling due to the thickness of the pressure-sensitive adhesive layer is not formed. Therefore, the thickness of that portion is almost the same as that of the non-adhesive portion, and even if this adhesive tape is wound in a roll shape, the thickness is constant, and creases do not occur.

使用できる。Since the pressure-sensitive adhesive is applied to both ends of the non-woven fabric, the pressure-sensitive adhesive layer can be temporarily attached to the front surface of the cathode ray tube without contacting the pressure-sensitive adhesive layer. Further, since the non-woven fabric and the pressure-sensitive adhesive are integrated, the non-woven fabric can be reused without being damaged when the pressure-sensitive adhesive tape is peeled off from the cathode ray tube after use.
【００１８】不織布の一面に熱可塑性樹脂層が積層され
