Definitions
- the present invention relates to a protective film with a pressure-sensitive adhesive layer with a separator, comprising a protective film with a pressure-sensitive adhesive layer that protects a liquid crystal screen and the like, and a separator that is bonded to the protective film and protects the pressure-sensitive adhesive layer of the protective film. .
- a uniaxially stretched film has a small amount of distribution, and it is not always easy to obtain a film that satisfies the characteristics (eg, very high flatness) required as a separator for a protective film with an adhesive layer.
- the present invention has been made in view of such circumstances, and provides a protective film with a pressure-sensitive adhesive layer comprising a biaxially stretched film and having a separator that can be easily divided.
- the separator is made of a biaxially stretched film and has a guide groove that serves as a guide for dividing the separator.
- the separator is divided along the guide groove, and the separator is partially peeled to partially expose the adhesive layer, and the exposed adhesive layer is attached to a liquid crystal screen or the like. Thereafter, the remaining part of the separator is peeled off, and the exposed adhesive layer is attached to the liquid crystal screen.
- the protective film is pasted by such a method, the finger does not touch the adhesive layer surface at the time of positioning, so that the adhesive layer surface is not soiled, and the protective film can be easily pasted at an accurate position.
- a conventional uniaxially stretched film can be replaced with a biaxially stretched film, thereby obtaining effects such as acquisition stability, acquisition cost reduction, and manufacturing cost reduction.
- the biaxially stretched film has a higher hardness than the uniaxially stretched film, when the hole is formed by punching the protective film with the adhesive layer with the separator, the protective film is hardly deformed around the hole.
- the separator using the uniaxially stretched film is easily torn, it was necessary to reduce the speed when the film with the pressure-sensitive adhesive layer and the separator were bonded together by roll-to-roll, but the biaxially stretched film was used. Since it is difficult to avoid the separator, the speed at the time of bonding can be increased, and the production efficiency can be improved.
- the separator has a split start portion that triggers splitting the separator along the guide groove.
- the division start portion is a cut, a notch, or a groove deeper than the guide groove.
- the division start portion extends from the end portion of the separator toward the guide groove.
- the division start portion is not in contact with the guide groove.
- the division start part is provided in at least two places across the guide groove.
- the guide groove is provided in at least two places so as to be substantially parallel.
- FIG. 2 is an end view taken along line AA in FIG. 1. It is a right view of FIG. 1 which shows the state by which the center part of a separator is pulled by the arrow X direction. It is a top view of embodiment whose division start part is a notch. It is a top view which shows the state which the division
- FIG. 12 is a plan view showing a state in which the separator is irregularly divided in the state of FIG. 11. It is a top view which shows the state from which the relative position of the guide groove and the cut
- FIG. 14 It is a top view which shows the state which the notch and the relative position of the cut
- FIG. 14 it is a top view which shows the state by which a separator is divided
- FIG. 1 is a plan view showing a configuration of a protective film with a pressure-sensitive adhesive layer with a separator according to an embodiment of the present invention
- FIG. 2 is an end view taken along line AA in FIG. 1
- FIG. FIG. 2 is a right side view of FIG. 1.
- the protective film with a pressure-sensitive adhesive layer with a separator includes a film with a pressure-sensitive adhesive layer 1 and a separator 3 bonded to the film 1, and the separator 3 is made of a biaxially stretched film and A guide groove 5 serving as a division guide is provided.
- the film 1 with the pressure-sensitive adhesive layer is composed of a base material 1 a and a pressure-sensitive adhesive layer 1 b, and the surface on the pressure-sensitive adhesive layer 1 b side is bonded to the separator 3.
- the film 1 with a pressure-sensitive adhesive layer a film having flatness and transparency that can be used for protecting a liquid crystal screen or the like can be used, and its configuration is not particularly limited.
- the separator 3 is made of a biaxially stretched film.
- the greatest reason for using a biaxially stretched film is its availability. Since the distribution amount of the biaxially stretched film is much larger than that of the uniaxially stretched film, obtain a product having properties (flatness, thickness, strength, etc.) desired as a separator for a protective film with an adhesive layer. Is much easier. Therefore, the “biaxially stretched film” of the present invention should be interpreted as widely as possible. As long as the function as the separator 3 is exhibited, the material and stretch ratio are not particularly limited, and the stretch ratios in the vertical and horizontal directions are different. May be.
- the problem with using a biaxially stretched film for the separator 3 is that the polymer is not oriented in one direction in the biaxially stretched film, so that it is not easy to cut straight, unlike a uniaxially stretched film.
- this problem can be solved by forming the guide groove 5 in the separator 3 and dividing the separator 3 along the guide groove 5 to solve the above-mentioned problem of using the biaxially stretched film.
- the width and depth of the guide groove 5 formed in the separator 3 are appropriately set so that the separator 3 is appropriately divided along the guide groove 5.
- the depth of the guide groove 5 is about half of the thickness of the separator 3, but may be deeper or shallower as long as the guide groove 5 exhibits its function.
- the guide groove 5 does not reach the pressure-sensitive adhesive layer 1b.
- the pressure-sensitive adhesive layer 1b is deteriorated by exposure to the outside air, and a line appears at a position corresponding to the guide groove 5 when the film 1 is attached to a liquid crystal screen or the like. Because there are cases.
- the separator 3 has a division start portion that becomes a trigger for dividing the separator 3 along the guide groove 5.
- the present invention can be implemented even without the division start portion.
- the separator 3 is thick, or when the guide groove 5 does not reach the end of the separator 3, the guide groove 5 is aligned. It may not be easy to divide the separator 3 (requires a large force). Therefore, if the separator 3 is provided with a division start portion and the separator 3 is divided starting from the division start portion, the separator 3 can be divided easily.
- the division start portion is not particularly limited as long as it is a starting point for dividing the separator 3, and may be any one of the cut line 7, the cutout 11, or a groove deeper than the guide groove 5.
- the cut means a part where the separator 3 is cut in a line shape, and the notch means a part where the separator 3 is cut out so that a vertex is formed at the tip as shown in FIG.
- the groove deeper than the guide groove 5 is, for example, a groove having a depth corresponding to most of the thickness of the separator 3 (for example, 90%). When such a deep groove is formed, the separator 3 is easily cut in this groove, so that it functions as a division start portion like the cut 7.
- the division start portion is a cut 7 extending from the end of the separator 3 toward the guide groove 5.
- two guide grooves 5 are provided substantially in parallel, and for each guide groove 5 there are two cuts 7 so as to sandwich the guide groove 5 (with respect to the guide groove 5, A cut 7a on the side close to the center of the separator 3 and a cut 7b on the side away from the center are provided.
- two cuts 7 are provided at both ends of the guide groove 5, a total of four cuts 7 are provided for one guide groove 5.
- the two cuts 7 are provided at both ends of the guide groove 5 so that the central portion 3a of the separator 3 can be peeled off from either side of the separator 3, so that both left-handed and right-handed This is to make it easier for users to use.
- the reason why the cuts 7a and 7b are provided on both sides of the guide groove 5 is that, as shown in FIG. 7, when the user pulls the central portion 3a of the separator 3 in an oblique direction, the outer two cuts 7a. As shown in FIG. 8, the division starts from two cuts 7a and 7b extending in the direction close to the user's pulling direction, so that the separator 3 can be divided more smoothly. This is because it becomes possible.
- the number of the cuts 7 provided in each guide groove 5 is preferably four.
- the cuts 7a and 7b may be provided only at one end of the guide groove 5, and one cut 7 is provided as shown in FIG. Only one may be provided.
- the cut 7 and the guide groove 5 may be in contact with each other as shown in FIG. In this case, there is an advantage that the division proceeds along the guide groove 5 immediately after the separation of the separator 3 starts. However, due to manufacturing tolerances or the like, as shown in the dotted circle 7c in FIG. 11, if the cut 7 slightly exceeds the guide groove 5, the separator 3 is formed in the guide groove 5 as shown in FIG. There is a problem that the separator 3 is irregularly divided without being divided along. In the present embodiment, the cut 7 and the guide groove 5 are not in contact with each other, and a space is provided between the two, so that even if the position of the cut 7 varies due to manufacturing tolerances or the like, the cut 7 is the guide groove. It is surely prevented from exceeding 5.
- the number of guide grooves 5 may be one as shown in FIG. In this case, by grasping the lower side portion 3b of the separator 3 and pulling it toward the back side of the sheet of FIG. 16, the separator 3 can be divided and only the lower side portion 3b can be peeled off.
