Description

本発明は、指紋や足跡、タイヤ跡等の採取に使用するための鑑識用粘着シートに関し、特に、指紋・足跡等を採取した後に、証拠となる鑑識用粘着シートの改ざんを防止するための技術に関する。   The present invention relates to a pressure sensitive adhesive sheet for use in collecting fingerprints, footprints, tire marks, etc., and in particular, a technique for preventing falsification of a pressure sensitive adhesive sheet for evidence after collecting fingerprints, footprints, etc. About.

従来、指紋や足跡、タイヤ跡等の採取に使用するための鑑識用粘着シートとしては、例えば透明支持フィルムの片面にウレタン系粘着剤を塗布したものが知られている（例えば、特許文献１参照）。   Conventionally, as a pressure-sensitive adhesive sheet for identification for use in collecting fingerprints, footprints, tire marks, etc., for example, one in which a urethane-based adhesive is applied to one side of a transparent support film is known (for example, see Patent Document 1). ).

この粘着シートを用いて指紋を採取するためには、まず、採取対象面に粉末を刷毛などで少しずつ塗布し、穂先で軽く払うようにして指紋隆線の部分だけに粉末を付着させて指紋を浮き上がらせる。次いで、粘着シートの一端から剥離紙を兼ねた台紙を剥離して粘着面を採取対象面に当接し、さらに台紙を剥離しながら浮き上がらせた指紋を粘着面に転写させ、その後台紙を再び粘着面に貼り合わせる。最後に、台紙に採取時、採取場所等の必要事項を、台紙の裏面の情報記入欄に記入して、指紋採取を完了する。そして、このような粘着シートは、採取する対象の大きさに応じて、３分割〜９分割に切断して使用される場合があった。   In order to collect fingerprints using this adhesive sheet, first apply the powder to the surface to be collected little by little with a brush, etc. Lift up. Next, the backing sheet that also serves as the release paper is peeled off from one end of the adhesive sheet, the adhesive surface is brought into contact with the surface to be collected, and the fingerprint that has been lifted while peeling the mount is transferred to the adhesive surface, and then the backing paper is again attached to the adhesive surface. Paste to. Finally, when collecting on the mount, fill in the necessary information such as the collection location in the information entry field on the back of the mount to complete fingerprint collection. And such an adhesive sheet may be cut | disconnected and used for 3 to 9 division | segmentation according to the magnitude | size of the object extract | collected.

しかしながら、台紙は粘着シートから容易に剥離、再貼付できるものであり、保管時に粘着シートあるいは台紙を意図的に貼り変えることができる。また、台紙が粘着シートから自然に剥離し、粘着シートと台紙とが入り乱れる可能性もあった。   However, the mount can be easily peeled off and reattached from the adhesive sheet, and the adhesive sheet or the mount can be intentionally attached during storage. In addition, the backing sheet may be peeled off naturally from the adhesive sheet, and the adhesive sheet and the backing sheet may be confused.

この際、ステープラなどで台紙と粘着シートとを固定してもよいが、この場合にもステープラ針の針穴を合わせて、粘着シート若しくは台紙をすり変えることができる。また、台紙と粘着シートを貼り合わせた状態で他の固定用テープにより両者を固定した場合には、低速で固定用シートを剥離したり、ドライヤー等の熱源を用いて粘着剤を軟化させ剥離することにより、台紙の表面を傷つけることなく、しかも剥離した粘着シートを再貼付可能な状態で剥離することができるため、台紙と粘着シートとが同一に使用されたものであることの証明が困難な場合もあった。   At this time, the mount and the adhesive sheet may be fixed with a stapler or the like, but in this case as well, the adhesive sheet or the mount can be replaced by aligning the needle holes of the stapler needle. In addition, when both are fixed with another fixing tape with the backing sheet and adhesive sheet bonded together, the fixing sheet is peeled off at a low speed, or the adhesive is softened and peeled off using a heat source such as a dryer. Therefore, it is difficult to prove that the backing sheet and the adhesive sheet are used in the same manner without damaging the surface of the backing sheet, and the peeled adhesive sheet can be peeled in a re-applicable state. There was a case.

このため、指紋・足跡等を採取した後に、再度台紙が剥離され貼り変えられたことを直ちに判別可能にして、鑑識用粘着シートの証拠能力を高める必要があった。そこで、下記の特許文献２には、支持体の片面に粘着剤層を備えた粘着シート層とこれに再貼付可能に貼り合わせられた台紙層とからなる鑑識用粘着シート本体と、前記粘着シート層と前記台紙層とを貼り合わせた状態で両者を貼着固定する剥離判別用粘着テープとを備えたことを特徴とする鑑識用粘着シートが提案されている。また、剥離判別用粘着テープとして、支持体の片面に形成された皮膜層及びその皮膜層を覆う粘着剤層が備えられ、剥離判別用粘着テープを鑑識用粘着シート本体から剥離した場合に、前記皮膜層及び／又は粘着剤層が剥離判別用粘着テープの支持体から剥離されるものが開示されている。   For this reason, after collecting fingerprints, footprints, etc., it is necessary to immediately determine that the backing sheet has been peeled off and pasted again, and it is necessary to improve the evidence ability of the adhesive sheet for identification. Therefore, in the following Patent Document 2, the pressure-sensitive adhesive sheet main body composed of a pressure-sensitive adhesive sheet layer having a pressure-sensitive adhesive layer on one side of a support and a backing layer removably bonded thereto, and the pressure-sensitive adhesive sheet There has been proposed a pressure-sensitive adhesive sheet for identification, which includes a peeling discrimination pressure-sensitive adhesive tape that bonds and fixes both layers and the mount layer in a state of being bonded together. In addition, as a peeling discrimination adhesive tape, provided with a coating layer formed on one side of the support and an adhesive layer covering the coating layer, when the peeling discrimination adhesive tape is peeled from the identification adhesive sheet body, The film layer and / or the pressure-sensitive adhesive layer is disclosed that is peeled from the support of the peel-off determination pressure-sensitive adhesive tape.

しかしながら、上記のように剥離判別用粘着テープを鑑識用粘着シート本体に貼着固定する方法では、剥離判別用粘着テープの製造コストの増加に加え、その貼着工程の煩雑さやコスト増加の問題があった。また、指紋等を採取する際に、台紙層から粘着シート層を剥離しても、剥離判別用粘着テープを介して両者が連結されており、剥離判別用粘着テープの存在によって粘着シート層の取扱いに慎重を要するといった使用上の制約があった。更に、鑑識用粘着シート本体を分割・切断して使用する場合には、剥離判別用粘着テープの貼着された切断片のみが、改ざん防止機能を有することになり、鑑識用粘着シートの利用効率が低下するという欠点もあった。   However, in the method of sticking and fixing the peeling determination adhesive tape to the identification adhesive sheet body as described above, in addition to the increase in the manufacturing cost of the peeling determination adhesive tape, there are problems of the complexity of the sticking process and the cost increase. there were. In addition, even when the adhesive sheet layer is peeled off from the backing layer when collecting fingerprints, the both are connected via the adhesive tape for peeling discrimination. There was a limitation in use that requires careful attention. Furthermore, when the identification adhesive sheet main body is divided and cut for use, only the cut piece to which the peeling discrimination adhesive tape is attached has a function of preventing falsification, and the utilization efficiency of the identification adhesive sheet There was also a disadvantage that the decrease.

そこで、本発明の目的は、コストをほとんど増加させずに証拠の改ざん防止機能を付与でき、しかも剥離した粘着シート層の取扱いの制限がなく、切断使用にも対応することができる鑑識用粘着シートを提供することにある。   Therefore, the purpose of the present invention is to provide a function for preventing falsification of evidence without substantially increasing the cost, and there is no restriction on handling of the peeled adhesive sheet layer, and it can be used for cutting use. Is to provide.

上記目的は、下記の如き本発明により達成できる。
即ち、本発明の鑑識用粘着シートは、支持体の片面に粘着剤層を有する粘着シート層と、前記粘着剤層に再貼付可能に貼り合わせられる台紙層とを備えた鑑識用粘着シートにおいて、
前記粘着シート層における支持体の粘着剤層を有しない側の表面の一部に、表面記入欄を有することを特徴とする。 The above object can be achieved by the present invention as described below.
That is, the pressure-sensitive adhesive sheet for identification of the present invention is a pressure-sensitive adhesive sheet for identification provided with a pressure-sensitive adhesive sheet layer having a pressure-sensitive adhesive layer on one side of a support and a backing layer that can be reattached to the pressure-sensitive adhesive layer.
In the pressure-sensitive adhesive sheet layer, a surface entry column is provided on a part of the surface of the support that does not have the pressure-sensitive adhesive layer.

本発明の鑑識用粘着シートによると、粘着シート層の支持体の表面の一部に表面記入欄が設けられているため、採取した指紋・足跡等と表面記入欄は粘着シート層として、常に、一体化しており、採取した指紋・足跡等と表面記入欄とを分離することができないため、証拠の改ざんを確実に防止することができる。しかも、粘着シート層を台紙層から完全に分離できるので、剥離した粘着シート層の取扱いの制限がない。また、別途印刷等する工程やその情報を管理する工程が必要なく、コストをほとんど増加させずに証拠の改ざん防止機能を付与できる。更に、鑑識用粘着シートを分割・切断して使用する場合でも、所定の分割領域に応じて、粘着シート層の支持体の表面の一部に表面記入欄を設けるだけで、容易に対応できる。   According to the adhesive sheet for identification of the present invention, since a surface entry column is provided on a part of the surface of the support of the adhesive sheet layer, the collected fingerprint / footprint and the surface entry column are always as an adhesive sheet layer, Since they are integrated and the collected fingerprint / footprints cannot be separated from the surface entry field, falsification of evidence can be surely prevented. In addition, since the pressure-sensitive adhesive sheet layer can be completely separated from the mount layer, there is no restriction on handling of the peeled pressure-sensitive adhesive sheet layer. Further, there is no need for a separate printing process or a process for managing the information, and the function of preventing falsification of evidence can be provided with almost no increase in cost. Furthermore, even when the identification adhesive sheet is used after being divided and cut, it can be easily handled by providing a surface entry column on a part of the surface of the support of the adhesive sheet layer in accordance with a predetermined divided region.

上記鑑識用粘着シートにおいて、前記表面記入欄の面積は、１〜１００ｃｍ2であり、前記支持体の表面の５〜５０面積％であることが好ましい。表面記入欄の面積の面積が大きくなると、粘着シートにおける不透明の面積割合が多くなって、指紋・足跡等を採取したり、また、採取後に識別等を行ったりする際に不都合が生じるおそれがある。一方、表面記入欄の面積の面積が小さいと記入し難くなって、表面記入欄としての機能しないおそれがある。かかる観点から、前記表面記入欄の面積は、さらには２〜５０ｃｍ2であるのが好ましく、前記支持体の表面の５〜５０面積％、さらには１０〜３０面積％とするのが好ましい。 In the identification adhesive sheet, the area of the surface entry column is 1 to 100 cm 2 , and preferably 5 to 50% by area of the surface of the support. If the area of the front entry area increases, the opaque area ratio in the adhesive sheet increases, and there may be inconveniences when collecting fingerprints, footprints, etc., and identifying after collection. . On the other hand, if the area of the surface entry column is small, it becomes difficult to fill in and there is a possibility that the surface entry column will not function. From this viewpoint, the area of the surface entry column is preferably 2 to 50 cm 2 , and is preferably 5 to 50% by area, more preferably 10 to 30% by area, of the surface of the support.

上記鑑識用粘着シートにおいて、前記表面記入欄は、前記支持体の表面の縁部に設けられていることが好ましい。前記表面記入欄が、前記支持体の表面の縁部に設けられていれば、指紋・足跡等を採取する際の障害にもならず、また、鑑識用粘着シート本体を分割・切断して使用する場合においても、所定の分割領域に応じて、記録欄が所定の縁部になるように、容易に切断することができる。   In the identification pressure-sensitive adhesive sheet, it is preferable that the surface entry column is provided at an edge of the surface of the support. If the surface entry field is provided at the edge of the surface of the support, it will not be an obstacle when collecting fingerprints, footprints, etc., and the identification adhesive sheet body is divided and cut for use. Even in this case, according to a predetermined divided area, the recording column can be easily cut so as to have a predetermined edge.

上記鑑識用粘着シートにおいて、前記表面記入欄は、前記支持体の表面の角部に設けられていることが好ましい。前記表面記入欄が、前記支持体の表面の角部に設けられていれば、指紋・足跡等を採取する際の障害にもならず、また、鑑識用粘着シート本体を分割・切断して使用する場合においても、所定の分割領域に応じて、記録欄が所定の角部になるように、容易に切断することができる。   In the identification adhesive sheet, the surface entry column is preferably provided at a corner of the surface of the support. If the surface entry field is provided at the corner of the surface of the support, it will not be an obstacle when collecting fingerprints, footprints, etc., and the identification adhesive sheet body is divided and cut for use. Even in this case, according to a predetermined divided area, the recording column can be easily cut so as to have a predetermined corner.

上記鑑識用粘着シートにおいて、前記台紙層は、裏面に記入欄を有することができる。台紙層の裏面に設ける裏面記入欄は、従来と同様に、裏面全面に設けることができ、指紋等に係わる採取物の情報を詳細に記入することができる。また、表面記入欄と裏面記入欄の項目に、それぞれ、識別情報欄を設けておいて、当該識別情報欄に同じ記号、符号等を用いること等により、表面記入欄と裏面記入欄の情報を一致させて、鑑識用粘着シートの改ざん防止機能や、台紙と粘着シートが入り乱れて混乱するのを防止することができる。また、このように、表面記入欄と裏面記入欄を設けることにより、表面記入欄の大きさを小さく制御でき、指紋・足跡等の採取、採取後の識別等を容易に行うとともに、鑑識用粘着シートの改ざん防止を防止することができる。   In the identification adhesive sheet, the mount layer may have an entry column on the back surface. The back-surface entry column provided on the back surface of the mount layer can be provided on the entire back surface as in the prior art, and information on the collected material related to fingerprints and the like can be entered in detail. In addition, by providing an identification information column for each item in the front surface entry column and the back surface entry column, and using the same symbol, code, etc. in the identification information field, the information in the front surface entry column and the back surface entry column is changed. By matching, it is possible to prevent falsification of the identification adhesive sheet and to prevent the mount and the adhesive sheet from being confused and confused. In addition, by providing the front and back side entry fields in this way, the size of the front side entry field can be controlled to be small, and fingerprints, footprints, etc. can be easily collected and identified after collection. It is possible to prevent the sheet from being tampered with.

以下、本発明の実施の形態について、図面を参照しながら説明する。図１（Ａ）、（Ｂ）は、本発明の鑑識用粘着シートの一形態を示す断面図である。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 (A) and 1 (B) are cross-sectional views showing one embodiment of the pressure-sensitive adhesive sheet for identification of the present invention.

本発明の鑑識用粘着シートは、図１（Ａ）に示すように、支持体１ａの片面に粘着剤層１ｂを有する粘着シート層１と、前記粘着剤層１ｂに再貼付可能に貼り合わせられる台紙層２とを備えるものである。そして、粘着シート層１における支持体１ａの粘着剤層１ｂを有しない側の表面１ｓの一部に、表面記入欄３を有するものである。   As shown in FIG. 1 (A), the pressure-sensitive adhesive sheet for identification of the present invention is bonded to the pressure-sensitive adhesive layer 1b having the pressure-sensitive adhesive layer 1b on one side of the support 1a so as to be re-stickable. The mount layer 2 is provided. And it has the surface entry column 3 in a part of surface 1s of the side which does not have the adhesive layer 1b of the support body 1a in the adhesive sheet layer 1. FIG.

粘着シート層１は、例えば透明なフィルムからなる支持体１ａのいずれか一方の面に、感圧性粘着剤からなる粘着剤層１ｂが形成されており、採取対象面から浮き上がらせた指紋などを転写させるものである。   The pressure-sensitive adhesive sheet layer 1 has, for example, a pressure-sensitive pressure-sensitive adhesive layer 1b formed on one surface of a support 1a made of a transparent film, and transfers a fingerprint or the like lifted from the surface to be collected. It is something to be made.

支持体１ａは、指紋等の判別が可能な程度の透明性を有していればよいが、透明性が高いほど、指紋等の判別性が向上するため好ましい。支持体としては、例えば、ポリエチレンテレフタレートフィルム等のポリエステルフィルムが使用できる。粘着剤層１ｂについても、指紋等の判別が可能な程度の透明性を有していればよいが、透明性が高いほど、指紋等の判別性が向上するため好ましい。   The support 1a only needs to be transparent enough to distinguish fingerprints and the like, but the higher the transparency, the better the fingerprints and the like. As the support, for example, a polyester film such as a polyethylene terephthalate film can be used. The pressure-sensitive adhesive layer 1b only needs to be transparent enough to distinguish fingerprints and the like, but the higher the transparency, the better the distinguishability of fingerprints and the like.

鑑識用粘着シートにおける粘着剤層１ｂとしては、タックが低くいにも係わらず指紋等の凹凸に良好に追従して正確に痕跡の採取が行える観点から、ウレタン系粘着剤を用いたものが好ましい。   The pressure-sensitive adhesive layer 1b in the identification pressure-sensitive adhesive sheet is preferably a urethane-based pressure-sensitive adhesive from the viewpoint of accurately following traces such as fingerprints and accurately collecting traces despite having a low tack. .

台紙層２は、その一方の面が粘着剤層１ｂを再貼付可能なだけの剥離性を有していればよい。このため、台紙層２は、紙を基材とするものに限定されず、単一の着色フィルムなどで構成することも可能である。   The backing layer 2 only needs to have a peelability that allows one side of the backing layer 2 to re-stick the adhesive layer 1b. For this reason, the mount layer 2 is not limited to one having paper as a base material, and can be composed of a single colored film or the like.

好ましい台紙層２としては、例えば、ポリプロピレン製などの合成紙や上質紙、ケント紙等からなる基材層２ｃと、基材層２ｃの表面側に設けられて黒色又は白色などに着色された印刷層２ｂと、その表面に設けられた剥離層２ａとからなるものが挙げられる。また図１（Ｂ）に示すように、基材層２ｃの裏面側にも、裏面記入欄としての印刷や表示が可能な印刷層２ｄを設けることができる。   As the preferable mount layer 2, for example, a base material layer 2 c made of synthetic paper such as polypropylene, high-quality paper, Kent paper, or the like, and a printing layer provided on the surface side of the base material layer 2 c and colored black or white The thing which consists of 2b and the peeling layer 2a provided in the surface is mentioned. Further, as shown in FIG. 1B, a printing layer 2d capable of printing and display as a back side entry column can be provided on the back side of the base material layer 2c.

印刷層２ｂと剥離層２ａとは、１つの層で形成することも可能であり、例えば離型性の黒色又は白色のプラスチックフィルムから構成することができる。   The print layer 2b and the release layer 2a can be formed as a single layer, and can be formed of, for example, a releasable black or white plastic film.

このような鑑識用粘着シートは、特開２００１−４０２９９号公報に記載された鑑識用粘着シートや特開平３−８０８３３号公報に記載された鑑識用粘着シートなど、多数の技術が公知であり、本発明はこれら公知の鑑識用粘着シートの何れにも適用することが可能である。   Many such techniques are known, such as the pressure sensitive adhesive sheet described in JP-A-2001-40299 and the pressure-sensitive adhesive sheet described in JP-A-3-80833. The present invention can be applied to any of these known forensic pressure-sensitive adhesive sheets.

表面記入欄３としては、事件番号や採取日時、立会人氏名等を記入するための表示が挙げられる。表面記入欄３は、支持体１ａの表面１ｓに、剥がれないように接着、固定される。また、印刷層２ｄとして、裏面記入欄を設ける場合には、表面記入欄３は、裏面記入欄との識別の一致を行うことができる程度の欄または項目を設けるのみでもよい。また単に、裏面記入欄との識別の一致を行うことができる記号または符号のみを記すシール、ラベル等を貼るのみでもよい。   The surface entry field 3 includes a display for entering the case number, collection date and time, witness name, and the like. The surface entry column 3 is adhered and fixed to the surface 1s of the support 1a so as not to peel off. When the back surface entry field is provided as the printed layer 2d, the front surface entry field 3 may be provided only with a field or item that can be matched with the back surface entry field.
