Description

ARTICLE 8 TRANSFERABLE COVERING TECHNICAL FIELD The present invention relates to an article with transferable coating comprising a support having thereon provided with a removable coating substrate, wherein only the coating substrate is transferable to an adherent.

BACKGROUND OF THE INVENTION The transferable coating articles used to correct a part of a document or to erase or cover a part of the letters therein are already known. For example, in the past, there were articles comprising removable paper such as the support that had laminated on itself a substrate that had a property to cover. In the case of this type of articles, a permanent adhesive was usually covered on the surface of the substrate to be brought into contact with a removable paper. To transfer this substrate to an adherent, the substrate peeled off the removable paper and overlapped and pressed into a predetermined adherent. Adhesion to the adherent required precise placement, however in general it was very difficult to perform the correct positioning while only a substantially adhesive substrate detached from the removable paper was to be removed by hand. In addition, it was impossible to release again the substrate bonded to the adhesive with the permanent adhesive. This last inconvenience was overcome using a removable adhesive, but the difficulty in placing it was not able to be solved, and therefore, after repeated bonding, the adhesive used was stained by hand, and suffered from a reduction in adhesion, or dirtying. the adherent These types of items are currently not used. The transferable cover articles currently used are roughly classified into those of the sheet type and the type of tape. Examples of sheet type articles are those sold by Coal Paper, under the trademark of "Union Decadry Fasto", and typing error correction tapes, Tipp-Ex (registered trademark), available from Ko uyo Co., Ltd .. Ribbon type items can be used by correction tapes, WHIPER (registered trademark), of Plus Co., Ltd., correction tapes, Rimuka (registered trademark), of Nichiban Co., Ltd., and those sold by Kokuyo Co., Ltd., - under the Keshipita trademark. Of these up to now transferable cover tapes, those of the sheet type and some of the tape type (the former WHIPER of Plus Co., Ltd., Keshipita of Kokuyo Co., Ltd., etc.) comprise a release paper transparent or translucent having thereon a coating layer having an adhesive property, such as a white ink on the covered surface on exposure, is superimposed on a predetermined adherent (e.g., on the portion of a document where the letters that are intended to be corrected or covered, are written), and pressed to transfer the coated layer to the adherent. In this case, due to the limitation in the thickness of the coating layer, when transferred as a coating, the letters under the coated coating transferred, are sometimes read through it, and the coating effect is not satisfactory. Also, when the transfer is intended to be removed, or it is planned to reveal the covered letters again, the coated layer once transferred is very difficult to detach without deteriorating the adherent. The rest of the above type of transferable coating articles comprise a tape substrate having a removable adhesive applied thereto, and rolled. An example of the same is the former Rimuka from Nichiban Co., Ltd .. In the case of this type of articles, the coating tape is unwound, cut to a required length, superimposed on a location to be covered, and Press to cover yourself. Since the usable adhesive is removable, the coating tape can be removed later. Nevertheless, since both ends of the cut tape must be held with the fingers during the coating operation, this type of transferable cover articles can not avoid being stained in the portions of the fingers. The stain on the side to be adhered to an adherent causes poor adhesion to the adherent, and the stain on the exposed side after adhesion to the adherent is not aesthetically preferred, which results in a problem particularly when copying. Further, when the adhesion operation is repeated because the tape does not adhere to a given location, the problems accompanying the staining become, in an increased manner serious.

BRIEF DESCRIPTION OF THE INVENTION The present invention provides a new type of a transferable coating article, capable of a correct adhesion of the coating substrate to an adherent, without staining a substrate, the article has sufficient coating strength and is also capable of being removed.

DESCRIPTION OF THE PREFERRED MODALITIES The transferable cover article of the present invention comprises a light transmitting support and a laminated coating substrate in the support, through a removable adhesive, the substrate is smaller than the support, and the removable adhesive is laminated to the substrate. the surface of the substrate that is not oriented to the support.

The coating substrate for use in the transferable coating article of the present invention can be any, provided it is a tape or sheet material having a sufficient covering property. The term "property to cover" as used in the present invention means a function that completely or almost completely prevents a person from seeing through the substrate, letters, figures or characters written or printed on an adherent. When copying a document, or the like, that has a coating substrate transferred thereto, preferably the substrate itself is not copied as a shadow. Representative examples of the substrate having such a covering property include paper materials and plastic materials. The color of the material is not particularly restricted, however, in the case where the adherent to which a coating substrate is transferred is a document, the coating substrate may preferably be white or almost white. Examples of effective white substrates include a free wood paper having coated therein a white pigment, such as titanium white, or calcium carbonate, a plastic film having mixed therein, the white pigment described above and a plastic film having coated or printed thereon, the white pigment described above. White substrates of tapes or sheets conventionally used for coating articles can also be used. The thickness of the substrate is conveniently 50 to 150 μm, the covered part is contrasted, the substrate transferred to an adherent gives the sensation of foreign matter and it is very likely that the substrate is copied as a shadow. The support used in the present invention must transmit the light, to facilitate fixing, through the support, a position where the substrate joins under pressure in the transfer of the substrate to an adherent. The support must, of course, be visually distinguishable from the adherent and also from the substrate. Examples of the support for use in the present invention include transparent or light-transmitting plastic materials, such as polyethylene, polypropylene, vinyl chloride and polyester. A general purpose support in the form of a tape or sheet, known as an "application tape" or "application sheet" made of the materials described above, can also be used in the present invention. The thickness of the plastic material used as support is conveniently 50 to 150 μm. If the thickness is less than 50 μm, the support can easily wrinkle in the coating operation, causing difficulties in the correct bonding of the substrate to the coated part in an adherent, while if the thickness exceeds 150 μm, the support can hardly be removed after the adhesion of the substrate to the coated part. In the use of the transferable cover article of the present invention, the article is positioned so that the substrate can be fixed to a predetermined portion of an adherent, and then pressed thereon and only the support can be removed to leave the substrate adhered to the substrate. coating portion. Accordingly, it is important in the present invention that the substrate be smaller than the support. Because of this, also, the coating part in the adherent can be confirmed through the support that transmits the light in the coating operation. In addition, the fingers can take the transferable cover article without coming in contact with any or almost any part of the substrate, and consequently, it prevents the substrate from deteriorating in adhesion to the substrate, due to the substrate stain, which is advantageous in the need to re-treat the coating operation. The substrate and support can be of any form, as long as they satisfy the condition described above or the substrate is smaller than the support. For example, a transferable cover article may consist of a sheet-like support, and a plurality of substrates having independent forms laminated on the support. In this case, the substrates can all be of the same shape or they can have all different shapes. Also, a continuous or discontinuous substrate in the form of a ribbon can be laminated to a tape-like support. The removable adhesive used in the transferable cover article of the present invention may be any, provided that the substrate is only allowed to adhere to an adherent by peeling off the support to transfer the substrate to the coated part of an adherent and further, the substrate may be easily detached when the substrate is removed from the adherent later. Useful removable adhesives are exemplified by those known as weak self-adhesive adhesives, and those known as microsphere adhesives. For the materials for these adhesives, acrylic adhesives and rubber-based adhesives may be preferred. In particular, the mixture preferably has a high vitreous transition temperature, and for this purpose, an acrylic acid component can be increased in proportion, in the acrylic adhesive, or an adherent having a high melting point can be combined in the acrylic adhesive. the adhesive with rubber base. The removable adhesive is preferably coated to have a thickness of from 5 to 30 μm. If the thickness is less than 5 μm, the adhesive force is too low to bond the substrate to an adherent, whereas if it exceeds 30 μm, an excess of the adhesive protrudes and the substrate may not adhere to an adherent upon release of the support, and it can be removed while it is still attached to the support. In the present invention, the adhesive used to laminate the substrate in the support, and the adhesive laminated on the surface of the substrate, which come in contact with an adherent, when they are removable adhesives. These adhesives can be of the same or different kind. When both adhesives used are of the same kind, the adhesive strength of the substrate to an adherent may become greater than the adhesive strength of the adhesion support, adjusting the area of the substrate bonded to the adherent greater than the area of the bond attached to the adherent, so that the support can be detached from the substrate adhered to the adherent. When different kinds of adhesives are used, which can be adjusted in the same way, so that the adhesive strength of the substrate to an adherent can be greater than the adhesive strength of the support to the adherent. In the transferable cover article of the present invention, a coating substrate having laminated on a surface thereof, a removable adhesive, is laminated to a support that transmits light larger than the substrate through the removable adhesive, with the rear surface of the substrate oriented to the support. Because the support that transmits the light is larger than the substrate, the portion of an adherent in which the coating is intended can be easily confirmed through the support by joining the substrate to the relevant portion, and also, it can be prevented that the surface of the substrate, which is bonded to the adherent, becomes soiled due to the treatment of the transferable article with the hands in the coating operation. The coating substrate is attached to the coated part of an adherent, to hide letters and the like present underneath it. Due to the interposition of a removable adhesive between the support and the substrate, only the support can be removed after the attachment of the substrate to the adherent, and the substrate can be left adhered to the adherent, in addition, due to the removable adhesive laminated on the surface of the substrate. to be bonded to an adherent, the substrate can be subsequently removed from the adherent, if desired, to discover the covered part and also, adhesion to the adherent can be attempted again. The present invention will be described later in greater detail with reference to the accompanying drawings. A transferable cover article 10 of the present invention, of which a top view is shown in Figure 1 (a) and a cross section is shown in Figure 1 (b), has a constitution such that the leaf-like support which transmits the light 11 and a plurality of tape or sheet-like substrates 12 having a covering property, are laminated through removable adhesive layers 13 and a removable adhesive 14 is laminated to the surface of the substrate 12, on the side opposite to the support that transmits light 11 (on the surface that will later be attached to an adherent). An article having such a constitution can be used as a transferable cover sheet. As clearly seen in the cross section shown in Figure 1 (b), a release paper 15 treated with a release agent is further laminated to the surface of the substrate carrying an adhesive 14 of the transferable cover article 10 to protect the adhesive on the substrate. By using the transferable cover sheet shown in this figure, at least a portion of the transferable sheets are detached from the release paper, a substrate of appropriate size is attached to a predetermined portion of an adherent, the support is peeled from the substrate, and the transfer sheets that remain unused, are again superimposed on the release paper. The substrate attached to the adherent can be removed later.

A transferable cover article 20 within the present invention, of which a top view is shown in Figure 2 (a) and a cross section is shown in Figure 2 (b), has such a constitution to a support in the form of light transmitting tape 21 and the tape-like substrate 22 having a covering property, are laminated through a removable adhesive layer 23 and a removable adhesive 24, is laminated to the surface of the substrate 22 on the side opposite the support that transmits light 21 (on the surface that will later be attached to an adherent). An article having such a constitution can be used as a transferable coating tape. After coating a release agent on the back surface 28 of the holder 21, the tape is wound onto a rolled article. By using such a transferable coating tape, the tape is cut from the roll by a necessary length, the substrate is attached to a predetermined portion of an adhesive and the backing is detached from the substrate. The substrate that is added to the adherent can be removed later.

Ex «ampio An acrylic adhesive (SK Di e 1945, produced by Soken Kagaku KK) is coated in an amount of 20 g / m2 (coating thickness: 20 μm) on a surface of a free wood paper having a weight of 90 g / m2 (thickness: 100 μm) and the paper is cut to a size of 10 mm x 50 m to prepare a pressure sensitive adhesive sheet to be used as a coating substrate. A pressure sensitive adhesive tape obtained by coating the same acrylic adhesive on a transparent polypropylene film (Pylen (registered trademark) manufactured by Toyobo Co., Ltd.) in a size of 60 μm in thickness and 30 mm in width in an amount of 20 g / m2 (coating thickness: 20 μm) was superimposed on the back surface of the pressure sensitive adhesive sheet obtained above as a support. In addition, a silicone-based release agent (SIL-OFF294, produced by Dow Chemical) was coated on the back surface of the support and the coating was wrapped in a roll to produce a transferable coating tape. When measuring the adhesive strength of the transferable coating tape to an adherent (copy paper) according to JIS Z 0237, the adhesive hardness of the white sheet or tape (substrate) was 100 g / 25 mm and that of the transparent tape (support) was 80 g / 25 mm. Using this transferable coating tape, the white sheet as the substrate was fitted to the portion intended to be covered and pressed thereon, and only the transparent tape was removed from the adherent, then the white sheet could be transferred to the adherent.

As described in the above, the transferable cover article of the present invention, allows a person to see an adherent with the eyes through the support that is transmitted to the light, and therefore the one with the adherent portion to be coated, can be carried out accurately and easily. This is particularly advantageous when the portion to be coated is small. In addition, the substrate for use in the transferable cover article of the present invention may have an excellent coating property, unlike an ink cover film, and therefore, may achieve a complete coating. In addition, the transferable cover article of the present invention utilizes a removable adhesive, and therefore, adhesion to an adherent can be attempted again, the coating substrate can be removed from the adherent after it has been completed and the adherent is not rolled. with the detachment. In addition, the transferable cover article of the present invention comprises a support larger than the substrate, and therefore, adhesion to an adherent can be conducted without almost or no stain by the fingers and the substrate can be bonded to the adherent without failure. It is noted that in relation to this date, the best method known by the applicant to carry out the aforementioned invention, is the conventional one for the manufacture of the objects to which it relates. Having described the invention as above, property is claimed as contained in the following:
