Description

【０００１】
【産業上の利用分野】
本発明は、感圧複写用紙に関する。さらに詳しくは、一枚ものの用紙からなる改ざん防止機能を有する感圧複写用紙であって、用紙面に汎用ノンインパクトプリンター等の印字装置でユーザー固有の可変情報を印字記録して利用し得、それ自身をＳ字状またはＺ字状に３つ折りに折ることで、筆記による感圧複写機能を発揮し得る感圧複写用紙に関する。
【０００２】
【従来の技術】
従来の感圧複写用紙（シート）は、例えば、特開平８−２３０３１７号公報にみられるように、一方の用紙基材の裏面に発色剤を塗布し、他方の用紙基材の表面に顕色剤を塗布し、それぞれの用紙端部を接着剤で接着することにより複数枚の用紙を重ね合わせた構成の、いわゆる複写シート組が挙げられる。
また、単票の用紙からなる感圧複写式情報記録用紙としては、特開平９−２０７４３３号公報が挙げられる。同公報の一枚ものの用紙からなる複写シートの構成は、シート基材面の全面に顕色剤層を設け、該顕色剤層の表面所定部分に減感インキ層を設け、該減感インキ層の表面に発色剤層を設けた感圧複写シートである。
【０００３】
従来の帳票類は、量産印刷による固定情報のみを付与したものであった。しかしながら、近年は、帳票類の形態に対する嗜好が、従来の固定情報のみのものに加えて、後からユーザーの目的に応じて必要な書式や情報を、固定情報に追加して印字（オーバーレイ印刷）できるものが求められるようになっている。感圧複写シートからなる帳票類も同様である。
特開平８−２３０３１７号公報に開示の構成の感圧複写シートは、顕色剤を塗布形成した用紙と、発色剤を塗布形成した用紙とを、別々に用意し、その後に重ね合わせて、両用紙端部を接着や密着等の手段で接合して用いる、いわゆる複写帳票組と称されるものである。当該複写帳票組に対する顧客の個別情報の印字は、インパクトプリンター（ドットプリンターともいう。）を用いて、重ね合わされた帳票の表面から圧力を加えて印字する必要がある。
しかしながら、近年、追加する可変情報をオーバーレイ印刷する手段は、印刷品質、コスト、処理速度の面から見てインパクトプリンターからノンインパクトプリンターに変わってきている。そのため、このような重ね合わせ方式の複写帳票組に可変情報をオーバーレイ処理するには、わざわざインパクトプリンターを別に用意する必要がある、という課題がある。
【０００４】
特開平９−２０７４３３号公報に開示の構成の感圧複写シートによれば、全面に設けた顕色剤層上の一部に減感インキ層を介して発色剤層を設け、該発色剤層を内側にして折り畳むことで、用紙裏面からの筆記圧により発色剤の一部が顕色剤層面に転移して文字等を顕色剤層表面に表示することができる。
しかしながら、減感インキ層を設けたとは云うものの、自己発色性であるため筆記圧が加わり、発色剤マイクロカプセルが破れると、発色剤はオイル状であるため、発色剤が、減感インキ層をとおして、該減感インキ下層の顕色剤と反応するため、当該筆記部分に滲んだ画像ができる。また、単に積み重ねて保存しておくだけでも条件によっては、減感インキ層を介して顕色剤と発色剤が反応してしまい、用紙表面が汚れたような状態になる、という課題がある。
【０００５】
【発明が解決しようとする課題】
そこで、本発明では、折り畳んで使用、特にＳ字状またはＺ字状に３つ折りに折ることにより感圧複写用紙の機能を発揮でき、単票の状態でユーザーにおいて可変情報をオーバーレイ印刷し易く、かつ金額等の所定の筆記後には、当該部分の改ざんが困難な一枚ものの複写用紙を提供すべくなされたものである。
【０００６】
【課題を解決する手段】
上記課題を解決する本発明の要旨の第１は、感圧複写記録面の全面または一部に可変情報を印字して用い得る感圧複写用紙であって、当該感圧複写用紙を構成する基材裏面の第１の部分に発色剤層を設け、該発色剤層の上の一部に転移性自己発色剤層を設け、前記基材裏面の第２の部分に顕色剤層を設け、感圧複写用紙をＳ字状またはＺ字状に３つ折りに折った際に、少なくとも、前記発色剤層の一部と前記顕色剤層の一部、および、前記転移性自己発色剤層の一部と前記顕色剤層の一部が対面して重なり合うことを特徴とする感圧複写用紙、にある。かかる感圧複写用紙であるので、筆記または印字事項の改ざんが困難となる。
【０００７】
上記課題を解決する本発明の要旨の第２は、感圧複写記録面の全面または一部に可変情報を印字して用い得る感圧複写用紙であって、当該感圧複写用紙を構成する基材裏面の第１の部分に第１の発色剤層、基材裏面の第２の部分に第１の顕色剤層、該第１の発色剤層の上の一部に第１の転移性自己発色剤層を設け、基材表面の第２の部分に第２の発色剤層を設け、基材表面の第３の部分に第２の顕色剤層を設けており、感圧複写用紙をＳ字状またはＺ字状に３つ折りに折った際に、少なくとも、前記第１の発色剤層の一部と前記第１の顕色剤層の一部、および、前記第２の発色剤層の一部と前記第２の顕色剤層の一部が対面して重なり合い、さらに、前記第１の転移性自己発色剤層と第１の顕色剤層とが重なり合うことを特徴とする感圧複写用紙、にある。かかる感圧複写用紙であるので、筆記または印字事項の改ざんが困難となる。
【０００８】
【発明の実施の形態】
以下、図面を参照して、本発明の感圧複写用紙の実施形態を詳述する。本発明の感圧複写用紙には、実施形態Ｉ．と実施形態II．とがあるので、それぞれについて、以下順次説明する。
図１は、本発明の実施形態Ｉ．の感圧複写用紙をＳ字状またはＺ字状に３つ折りに折って使用する状態の断面図、図２は、同平面に展開した場合の断面図、図３は、同平面に展開した場合の平面図を示す図である。
【０００９】
図１のように、本発明の実施形態Ｉ．の感圧複写用紙は単票の用紙からなる。図１において、符号１０は複写用紙の基材、１３ａ，１３ｂは折り線を示す。折り線１３ａ，１３ｂは通常は複写用紙を３つの部分にほぼ等分するように設けられるが等分でなくても発色剤層と顕色剤層の少なくとも一部が重なり合えば複写用紙の機能を果たすことができる。図１では折った断面状態が矩形状に図示されているが図示の都合上で、実際には紙であるから平面的な状態に折られる。
図１のように、Ｓ字状またはＺ字状に３つ折りに折った状態では、基材１０の第１の部分１０１裏面に設けられた発色剤層１１と基材１０の第２の部分１０２裏面に設けられた顕色剤層２１が対面する状態になる。この状態で用紙の表面から筆記具３０またはインパクトプリンタ等により記録することにより発色剤層１１と顕色剤層２１が「反応Ａ」し、顕色剤層が発色する。なお、用紙の表面、裏面とはいずれがどちらであっても構わないが便宜上、筆記等する側を表面としその反対面を裏面とすることにする。また、用紙をＳ字状またはＺ字状に３つ折りにして使用する際の筆記具等が接触する上面部分を第１の部分１０１、中折り部分を第２の部分１０２、最下面部分を第３の部分１０３ということにする。
【００１０】
発色剤層１１の一部には転移性自己発色剤層１２が設けられていて、当該部分に筆記具３０またはインパクトプリンタ等による筆圧等がかかった場合は、顕色剤層２１との間で、発色剤層１１と転移性自己発色剤層１２との混合による他の部分とは異なる色、すなわち特色に発色して顕色剤層側に転移して「反応Ｂ」する特性を有する。発色剤層１１と転移性自己発色剤層１２との混合色はそれ自体で発色、転移するので、顕色剤層２１がなくても使用できるが発色濃度がやや低くなる。かかる転移性自己発色剤層部は特色であるので、用紙の第２の部分に転移した場合に他の部分と異なる発色となり、当該部分の改ざんを困難にするとともに改ざんの発見を容易にすることができる。
図２の平面に展開した場合の断面図のように、発色剤層１１は用紙の第１の部分裏面、顕色剤層２１は用紙の第２の部分裏面に塗布形成されており、第３の部分には塗布されていない。また、用紙の表面のいずれの部分にも感圧記録材料は塗布されないことになる。
【００１１】
図３は、実施形態Ｉ．の感圧複写用紙を平面に展開した平面図であって、図３（Ａ）は表面側、図３（Ｂ）は裏面側を示している。複写用紙の感圧記録材料塗布部と折り線のみ表示され、その他の印刷表示等は省略されている。図３（Ａ）のように、複写用紙は折り線１３ａ，１３ｂにより前記３つの部分１０１，１０２，１０３に分割されており、基材１０の１０１部分と１０２部分とが対面するように折り畳んで使用することになる。折り線１３ａ，１３ｂは切り取り可能なミシン目線であってもよい。表面側には前記のごとく感圧記録材料は塗布形成されていない。
図３（Ｂ）のように、複写用紙の裏面側には、用紙の第１の部分１０１に発色剤層１１を塗設しており、用紙の第２の部分に顕色剤層２１を塗設しており、当該発色剤層１１の一部に転移性自己発色剤層１２が設けられている。当該転移性自己発色剤層１２に対応する表面側には記入欄が設けら、領収金額とか、コード番号とかの特別の事項が記入されることになる。
自己発色剤層としてはマイクロカプセル化した顕色剤と発色剤とを２層に塗布したものあるいは混合して１層に塗布したもの等が使用でき、いずれも一般的に使用されている材料である。
【００１２】
図４は、本発明の実施形態II．の感圧複写用紙をＳ字状またはＺ字状に３つ折りに折って使用する状態の断面図、図５は、同平面に展開した場合の断面図、図６は、同平面に展開した場合の平面図を示す図である。いずれも第２の転移性自己発色剤層１２２を設けた例が図示されているが、当該第２の転移性自己発色剤層は設けなくてもよい。
【００１３】
図４のように、本発明の実施形態II．の感圧複写用紙も単票の用紙からなる。
図４のように、Ｓ字状またはＺ字状に３つ折りに折った状態では、基材１０の第１の部分１０１裏面に設けられた第１の発色剤層１１１と基材の第２の部分１０２裏面に設けられた第１の顕色剤層２１１が対面する状態になる。また、基材１０の第２の部分１０２表面には第２の発色剤層１１２が設けられ、第３の部分１０３表面に設けられた第２の顕色剤層２１２と対面する状態になる。
この状態で用紙の表面から筆記具３０またはインパクトプリンタ等により記録することにより第１の発色剤層１１１と第１の顕色剤層２１１が「反応Ａ」し、第１の顕色剤層２１１が発色する。また、第２の発色剤層１１２と第２の顕色剤層２１２が「反応Ｃ」し、第２の顕色剤層２１２が発色する。
【００１４】
第１の発色剤層１１１の一部には部分的に第１の転移性自己発色剤層１２１が設けられていて、当該部分に筆圧等がかかった場合は、第１の顕色剤層２１１との間で「反応Ｂ」し、他の部分とは異なる特色に発色して第１の顕色剤層２１１側に転移する特性を有する。同様に、必要により第２の発色剤層１１２の一部には部分的に第２の転移性自己発色剤層１２２が設けられていて、当該部分に筆圧等がかかった場合は、第２の顕色剤層２１２との間で「反応Ｄ」し、他の部分とは異なる特色に発色して第２の顕色剤層２１２側に転移する特性を有する。前記のように、この第１、第２の転移性自己発色剤層はいずれも自己発色、転移するので顕色剤層がなくても良いが、発色濃度がやや低くなることになる。
図５の平面に展開した場合の断面図のように、基材の１０１部分裏面に第１の発色剤層１１１と第１の転移性自己発色剤層１２１、１０２部分裏面に第１の顕色剤層２１１、１０２部分表面に第２の発色剤層１１２と第２の転移性自己発色剤層１２２が塗布形成され、１０３部分表面には第２の顕色剤層２１２が塗布されている。
【００１５】
図６は、実施形態II．の感圧複写用紙を平面に展開した平面図であって、図６（Ａ）は表面側、図６（Ｂ）は裏面側を示している。図６（Ａ）のように、複写用紙は折り線１３ａ，１３ｂにより３つの部分１０１，１０２，１０３に分割されており、表面側には、第２の発色剤層１１２と第２の顕色剤層２１２を塗設し、基材１０の１０２部分の第２の発色剤層１１２と１０３部分の第２の顕色剤層２１２とが対面するように折り畳んで使用することになる。また、必要により第２の発色剤層の一部に第２の転移性自己発色剤層１２２を設ける。
図６（Ｂ）のように、複写用紙の裏面側には、第１の発色剤層１１１と第１の顕色剤層２１１を塗設しており、当該第１の発色剤層の一部に第１の転移性自己発色剤層１２１が設けられている。
当該第１および第２の転移性自己発色剤層１２１，１２２に対応する表面側には記入または印字欄が設けられ、領収金額とか、コード番号とかの特別の事項が記入されることになる。
【００１６】
図３、図６では、白紙の用紙からなり印刷は省略されているが用紙に共通に必要な固定情報を予め印刷して施しておいても良い。
ユーザーが設ける文字、数字や記入欄の罫線等の固有の可変情報は、この感圧複写用紙の表裏の発色剤層、顕色剤層の塗布領域のいずれの部分にも印刷形成することができる。
【００１７】
次に、本発明の感圧複写用紙の使用方法について説明する。
図７は、本発明の感圧複写用紙を折り畳む工程と折り畳んだ後の状態を示し、図８は、感圧複写用紙（実施形態Ｉ．）に記入後再び平面状態に展開した状態を示す。本発明の感圧複写用紙の実施形態Ｉ．は、図７のように、折り線１３ａ，１３ｂから基材の１０２の部分が内側となるようにＳ字状またはＺ字状に３つ折りに折ると、すなわち図７（Ａ）の▲１▼→▲２▼の順序（または▲２▼→▲１▼）で折ると、基材表面の顕色剤層が形成されている領域が、発色剤層が形成されている領域に対面する。複写用紙の表面には、顧客の住所・氏名等記入欄１５と、転移性自己発色剤層が塗布された部分の表面には領収金額等記入欄１６が設けられている（図７（Ｂ））。
この状態で基材表面の住所・氏名等記入欄１５にボールペン等の筆記具またはインパクトプリンター等により記録することにより、筆記または印字圧により発色剤と顕色剤とが「反応Ａ」し、顕色剤層が発色する。また、領収金額等記入欄１６に記入することにより転移性自己発色剤層１２と顕色剤層２１が「反応Ｂ」して発色する。
このとき、転移性自己発色剤層１２の色素と発色剤層１１の色素とを異なる色の色素にしておくと、発色剤層１１と顕色剤層２１との「反応Ａ」により生ずる色と、転移性自己発色剤層１２の発色剤が顕色剤層２１との「反応Ｂ」により生ずる色とは、異なる色になる。
【００１８】
また、発色剤層１１の上に形成された、自己発色剤層１２は転移性のものであるから、筆記記録した際に、発色した転移性自己発色剤層の一部が、対向する顕色剤層２１上に「正パターン」の文字で転移する。また、転移性自己発色剤層には、発色剤層１１と転移性自己発色剤層１２とが反応するので前記筆記手段またはインパクトプリンターにより筆記または印字した文字と「逆パターン」の文字（鏡像）が形成される。このような転移性を有する顕色剤は、通常の顕色剤に、炭酸カルシウム、ワックスなどを添加することにより得られる。
【００１９】
図８のように、感圧複写用紙の表面から住所・氏名等記入欄１５に記入すると基材の第２の部分１０２裏面には、発色剤層１１と顕色剤層２１との「反応Ａ」により（ア）の色が発色し、領収金額等記入欄１６に「４０００」の数字を記入すると基材の第１の部分裏面には、発色剤層１１と転移性自己発色剤層１２との反応により（ウ）の色が発色し、基材の第２の部分１０２裏面には、発色剤層１１と転移性自己発色剤層１２と顕色剤層２１との「反応Ｂ」により（イ）の色が発色することになる。この場合、顕色剤層２１が無い場合は、（ア）の発色は得られないが（イ）の低下した色濃度の（イ´）色の発色は得られる。
【００２０】
図９は、感圧複写用紙（実施形態II．）に記入後再び平面状態に展開した状態を示す。本発明の感圧複写用紙の実施形態II．の場合は、図９（Ｂ）のように、基材の第３の部分１０３の裏面にも「正パターン」文字で、住所、氏名および領収金額等の転記がされることで実施形態Ｉ．の場合と相違する。第１の発色剤層、顕色剤層間と第２の発色剤層、顕色剤層間の発色を異なる発色にしておけば用紙の種別の違いが明瞭になる。
第２の転移性自己発色剤層１２２に対応する基材表面の第２の部分１０２または第３の部分１０３のみの部分に特定事項の記載欄を設けておけば、基材の第３の部分１０３の表面に特色に転移した記録を得ることができる。この記録は、第１の部分を除去して第２の部分表面からのみ記入することにすれば顧客に知り得ない情報等を記録することもできる。
【００２１】
図９のように、感圧複写用紙の表面から住所・氏名等記入欄に記入すると基材の第２の部分１０２裏面に（ア）の色が発色し、領収金額等記入欄裏面に（ウ）の色が発色し、基材の第２の部分１０２裏面には、（イ）の色が発色することは前記実施形態Ｉ．の場合と同様である。実施形態II．の場合は、第２の発色剤層１１２と第２の顕色剤層２１２との「反応Ｃ」により、（エ）の色が発色し、基材の第２の部分１０２表面には、第２の発色剤層１１２と第２の転移性自己発色剤層１２２との反応により（カ）の色が発色し、基材の第３の部分１０３表面には、第２の発色剤層１１２と第２の転移性自己発色剤層１２２と第２の顕色剤層２１２との「反応Ｄ」により（キ）の色が発色することになる。この場合、第２の顕色剤層２１２が無い場合は、（キ）の発色は得られないが（キ）の低下した色濃度の（キ´）色の発色は得られる。
【００２２】
本発明の感圧複写用紙１は、顕色剤層が形成されている基材１０の表面の全面または一部に、例えば、保険会社名、お客様番号、氏名、住所などの記入欄をノンインパクトプリンターを用いてオーバーレイ印刷することができる。図示はされていないが紙面を装飾する模様や地紋印刷等を設けておくのも好ましい。これらはユーザーが追加する可変情報に該当する。また、顕色剤層形成部分は、領収金額が書かれるので、領収金額等記入欄１６として位置表示枠を印刷しておくことが好ましい。
発色剤塗布領域は、複写がされないので設ける可変情報は複写を要しない注意書とか、装飾的模様や地紋印刷等が好ましいと考えられる。この部分の印刷は前記のようにマイクロカプセルの破壊を伴わないノーインパクトプリンターでするのが好ましい。
【００２３】
本発明の感圧複写用紙は、Ｓ字状またはＺ字状に３つ折りにし、記入または印字して使用し、顕色剤層に複写した後、折り線１３ａ，１３ｂを境に分離して用いるのが通常である。利用分野の一例としては、顕色剤層の形成されている１０２，１０３部分を支店、本店等の控え、発色剤層のみの形成されている１０１部分をお客様領収書とすることができ、あるいは１０１，１０２部分を支店、本店等の控え、１０３部分をお客様領収書とすることもできる。
可変情報としては、一般的には、本体用紙と控え用紙とを関連付ける共通番号、その他後から付与する情報があり、これらの情報を、本体用紙と控え用紙の両方に、同時に印字形成する必要がある。これらの情報は、各帳票ごとにユニーク情報である必要があり、予め印刷して設けても良く、使用に際してその都度、印刷しても良く、コンピューターからの情報を適宜印字できるプリンター装置が処理が適している。図示はしないが、第１の顕色剤塗布領域の裏面に印刷するのも自由である。
【００２４】
可変情報の形成手段としては、レーザービームプリンター、インキジェットプリンター、イオンプリンター感熱転写プリンター等のノンインパクトプリンター、ファクシミリ装置等を用いることができる。顧客が記入する個々に異なる個別情報は、勿論ノンインパクトプリンターで印字しても構わない。
【００２５】
なお、本発明の感圧複写用紙は、Ｓ字状またはＺ字状に３つ折りに折り畳む例について説明したが、３つ巻き折りの場合にも塗布位置を適宜変更することにより適用できる。本発明の感圧複写用紙の利用分野としては、生命保険や損害保険の申込書、領収書、口座振替依頼書、その他、各種製造業の納入書、物流伝票などが挙げられる。
【００２６】
（材料に関する実施例）
発色剤層、転移性自己発色剤層には、電子供与性の発色剤溶液をマイクロカプセル化して公知の手段でインキ化したものか使用でき、顕色剤としては電子受容性の顕色剤をインキ化したものを使用することができる。発色剤としては、スピロ系染料、フルオラン系染料、トリアリールメタン系染料、ジフェニルメタン系染料、チアジン系染料等が上げられるがこれらに限られるわけではない。
発色剤層、転移性自己発色剤層は、上記のような染料の中から、発色する色調が異なるものを組み合わせて用いる。具体的には、発色剤層の染料としては、３−フェニル−スピロ−ジナフトピラン（スピロ系染料）、転移性自己発色剤層の染料としては、３−ピペリジノ−メチル−７−フェニルアミノオラン（フルオラン系染料）を用いることができる。
また、転移性自己発色剤層は、転移性を持たせるために、通常の発色剤の構成の他に、流動性油分、ワックスを主成分とし、その他、必要に応じて、炭酸カルシウム、エチレン−酢酸ビニル共重合体、バインダー等を添加したインキを用いて形成する。
【００２７】
【発明の効果】
本発明の感圧複写用紙は、単に一枚ものの用紙からなるのでユーザー側において、固有の書式たる可変情報をノンインパクトプリンター等でオーバーレイ印刷するのに適するという効果がある。
基材上の折り線を境に発色剤層と、顕色剤層を塗り分けて、後からＳ字状またはＺ字状に３つ折りに折って使用する際に、発色剤と顕色剤とが反応するため、自己発色層を全面に設ける場合のように発色による汚れが生じないという効果がある。
基材表面の発色剤層と転移性自己発色剤層が重畳した部分では、発色剤と転移性自己発色剤による発色剤とが混ざった状態で反応するため、それぞれの発色剤による色調と異なる色調の正文字が、顕色剤層に現れる。従って、一旦、筆記により複写形成された文字は改ざんし難い、という効果がある。

[Industrial application fields]
The present invention relates to pressure sensitive copying paper. More specifically, it is a pressure-sensitive copying paper having a falsification preventing function consisting of a single sheet of paper, and can be used by printing and recording variable information unique to a user with a printing device such as a general-purpose non-impact printer. The present invention relates to a pressure-sensitive copying paper capable of exerting a pressure-sensitive copying function by writing by folding itself into three in an S shape or a Z shape.
[0002]
[Prior art]
In conventional pressure-sensitive copying paper (sheet), for example, as shown in Japanese Patent Application Laid-Open No. 8-230317, a color former is applied to the back surface of one paper substrate, and the color is developed on the surface of the other paper substrate. There is a so-called copy sheet set in which a plurality of sheets are overlapped by applying an agent and bonding the end portions of each sheet with an adhesive.
Japanese Patent Application Laid-Open No. 9-207433 is an example of a pressure-sensitive copying type information recording sheet made of a single sheet. A copy sheet composed of a single sheet of the publication has a developer layer provided on the entire surface of the sheet substrate, a desensitizing ink layer provided on a predetermined surface of the developer layer, and the desensitizing ink. A pressure-sensitive copying sheet in which a color former layer is provided on the surface of the layer.
[0003]
Conventional forms have been given only fixed information by mass production printing. However, in recent years, in addition to the conventional fixed information only, the form and information required for the user's purpose is added to the fixed information and printed (overlay printing). What can be done is being sought. The same applies to forms composed of pressure-sensitive copying sheets.
In the pressure-sensitive copying sheet having the configuration disclosed in Japanese Patent Application Laid-Open No. 8-230317, a sheet coated with a developer and a sheet coated with a color developer are prepared separately, and then superimposed on each other. This is a so-called copy form set in which the end portions of the paper are used by bonding or adhering means. To print individual customer information on the copy form group, it is necessary to apply pressure from the surface of the overlaid form using an impact printer (also referred to as a dot printer).
However, in recent years, the means for overlay printing variable information to be added has changed from an impact printer to a non-impact printer in terms of print quality, cost, and processing speed. Therefore, there is a problem that it is necessary to separately prepare an impact printer in order to perform overlay processing of variable information in such a superposed copy form set.
[0004]
According to the pressure-sensitive copying sheet disclosed in JP-A-9-207433, a color former layer is provided on a part of the developer layer provided on the entire surface via a desensitizing ink layer, and the color developer layer Is folded inward so that a part of the color developing agent is transferred to the surface of the developer layer by the writing pressure from the back side of the paper, and characters and the like can be displayed on the surface of the developer layer.
However, although the desensitizing ink layer is provided, it is self-coloring, so when the writing pressure is applied and the color former microcapsule is broken, the color former is oily, so the color former is not attached to the desensitizing ink layer. Through the reaction with the developer of the lower layer of the desensitizing ink, an image blurred in the writing portion is formed. Further, depending on the conditions, the developer and the color former may react through the desensitizing ink layer even if they are simply stacked and stored, and the paper surface becomes dirty.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the pressure-sensitive copying paper of the present invention will be described in detail with reference to the drawings. The pressure-sensitive copying paper of the present invention includes the embodiment I.I. And Embodiment II. Each will be described in turn below.
FIG. 1 shows an embodiment of the present invention. FIG. 2 is a cross-sectional view when the pressure-sensitive copying paper is folded in an S-shape or Z-shape, FIG. 2 is a cross-sectional view when deployed on the same plane, and FIG. 3 is when deployed on the same plane. It is a figure which shows the top view.
[0009]
As shown in FIG. The pressure-sensitive copying paper consists of a single sheet. In FIG. 1, reference numeral 10 denotes a copy paper base, and 13a and 13b denote folding lines. The fold lines 13a and 13b are usually provided so that the copy paper is divided into approximately three parts, but the function of the copy paper is not required if the color developer layer and the developer layer overlap at least partly. Can be fulfilled. In FIG. 1, the folded cross-sectional state is illustrated in a rectangular shape, but for the convenience of illustration, it is actually a paper and is folded into a planar state.
As shown in FIG. 1, the color former layer 11 provided on the back surface of the first portion 101 of the base material 10 and the second portion 102 of the base material 10 in a state of being folded in three in an S shape or Z shape. The developer layer 21 provided on the back surface is in a facing state. In this state, recording is performed from the surface of the paper by the writing tool 30 or an impact printer or the like, whereby the color developer layer 11 and the developer layer 21 “react A”, and the developer layer develops color. Note that either the front side or the back side of the paper may be either, but for the sake of convenience, the side to be written on is the front side and the opposite side is the back side. In addition, when the paper is folded in three in an S-shape or Z-shape, the upper surface portion with which the writing instrument or the like contacts is the first portion 101, the middle folded portion is the second portion 102, and the lowermost surface portion is the third portion. The portion 103 of FIG.

[0017]
Next, a method for using the pressure-sensitive copying paper of the present invention will be described.
FIG. 7 shows the step of folding the pressure-sensitive copying paper of the present invention and the state after the folding, and FIG. 8 shows the state where the pressure-sensitive copying paper (Embodiment I.) is filled and then developed into a flat state again. Embodiments of Pressure Sensitive Copy Paper of the Present Invention As shown in FIG. 7, it is folded in three in an S-shape or a Z-shape so that the portion 102 of the base material is inside from the fold lines 13a, 13b, that is, (1) in FIG. When folded in the order of (2) (or (2) → (1)), the area where the developer layer is formed on the surface of the substrate faces the area where the color former layer is formed. On the surface of the copy sheet, there are provided a customer address / name entry column 15 and a receipt amount entry column 16 on the surface of the portion coated with the transferable self-coloring agent layer (FIG. 7B). ).
In this state, by recording with a writing instrument such as a ballpoint pen or an impact printer in the address / name entry field 15 on the surface of the base material, the coloring agent and the developer react with the writing or printing pressure, and the color develops. The agent layer develops color. In addition, the transferable self-coloring agent layer 12 and the developer layer 21 are “reacted B” to develop color by filling in the receipt amount entry column 16.
At this time, if the dyes of the transferable self-color-developing layer 12 and the color-developing layer 11 are dyes of different colors, the color generated by the “reaction A” between the color-developing layer 11 and the developer layer 21 The color developing agent of the transferable self-coloring agent layer 12 is different from the color produced by the “reaction B” with the developer layer 21.
[0018]
In addition, since the self-color-developing layer 12 formed on the color-developing layer 11 is transferable, a portion of the color-transferring self-color-developing layer that is colored during writing is recorded. It is transferred on the agent layer 21 with the characters “normal pattern”. In addition, since the color former layer 11 and the transferable self color former layer 12 react with the transferable self color former layer, the characters written or printed by the writing means or the impact printer and the “reverse pattern” characters (mirror image) Is formed. A developer having such a transfer property can be obtained by adding calcium carbonate, wax or the like to a normal developer.
[0019]
As shown in FIG. 8, when the address / name entry field 15 is entered from the front surface of the pressure-sensitive copying paper, the “reaction A between the color former layer 11 and the developer layer 21 is formed on the back surface of the second portion 102 of the base material. The color of (a) is developed, and when a number of “4000” is entered in the receipt amount entry column 16, the color former layer 11, the transferable self color former layer 12, As a result of the reaction, the color of (c) is developed, and the back surface of the second portion 102 of the substrate is caused by the “reaction B” of the color former layer 11, the transferable self-color former layer 12, and the developer layer 21 ( The color of a) will develop. In this case, in the case where the developer layer 21 is not provided, the color development of (a) cannot be obtained, but the color development of (a ') having the reduced color density of (a) can be obtained.
[0020]
FIG. 9 shows a state in which the pressure-sensitive copying paper (Embodiment II) is developed into a flat state again after filling in. Embodiment of pressure-sensitive copying paper of the present invention II. In this case, as shown in FIG. 9 (B), the back of the third portion 103 of the base material is also transferred with the “normal pattern” characters, and the address, name, receipt amount, etc. are transferred. It is different from the case of. If the color development between the first color developer layer and the developer layer is different from the color development between the second color developer layer and the developer layer, the difference in paper type becomes clear.
If a description column for specific matters is provided only on the second portion 102 or the third portion 103 on the substrate surface corresponding to the second transferable self-coloring agent layer 122, the third portion of the substrate It is possible to obtain a record that has been transferred to the surface of 103. This record can record information that the customer cannot know if the first part is removed and the entry is made only from the surface of the second part.
[0021]
As shown in FIG. 9, when the address / name entry field is entered from the front surface of the pressure-sensitive copying paper, the color of (a) is developed on the back surface of the second portion 102 of the base material, and the receipt money amount entry field is The color of (a) is developed and the color of (a) is developed on the back surface of the second portion 102 of the substrate. It is the same as the case of. Embodiment II. In this case, due to the “reaction C” between the second color developer layer 112 and the second developer layer 212, the color of (d) is developed, and the surface of the second portion 102 of the substrate The color of (f) is developed by the reaction between the second color former layer 112 and the second transitional self-color former layer 122, and the second color former layer 112 and the surface of the third portion 103 of the substrate Due to the “reaction D” between the second transferable self-coloring agent layer 122 and the second developer layer 212, the color of (g) is developed. In this case, in the absence of the second developer layer 212, (ki) color development cannot be obtained, but (ki) color development with a reduced color density can be obtained.
[0022]
The pressure-sensitive copying paper 1 of the present invention has a non-impact on the entire surface or part of the surface of the base material 10 on which the developer layer is formed, such as an insurance company name, customer number, name, address, etc. Overlay printing can be performed using a printer. Although not shown in the figure, it is also preferable to provide a pattern for embellishing the paper or a background pattern printing. These correspond to variable information added by the user. Further, since the receipt amount is written in the developer layer forming portion, it is preferable to print the position display frame as the receipt amount entry column 16.
Since the color forming agent coating area is not copied, it is considered that the variable information provided is preferably a precautionary note that does not require copying, or a decorative pattern or tint block printing. The printing of this portion is preferably performed by a no-impact printer that does not involve destruction of the microcapsules as described above.
[0023]
The pressure-sensitive copying paper of the present invention is used after being folded in three in an S-shape or Z-shape, filled in or printed, copied to the developer layer, and then separated at the fold lines 13a and 13b. It is normal. As an example of the application field, the 102, 103 part where the developer layer is formed can be used as a copy of the branch, the head office, etc., and the 101 part where only the color developer layer is formed can be used as a customer receipt. The 101 and 102 parts can be used as a copy of a branch, the head office, etc., and the 103 part can be used as a customer receipt.
In general, the variable information includes a common number for associating the main body sheet and the copy sheet, and other information to be given later. It is necessary to print these information on both the main sheet and the copy sheet at the same time. is there. These pieces of information need to be unique information for each form, and may be printed in advance, and may be printed each time it is used. The printer device that can appropriately print information from the computer can process the information. Is suitable. Although not shown, printing on the back surface of the first developer application region is also free.
[0024]
As the variable information forming means, a laser beam printer, an ink jet printer, a non-impact printer such as an ion printer thermal transfer printer, a facsimile machine, or the like can be used. Of course, the individual information entered by the customer may be printed by a non-impact printer.
[0025]
The pressure-sensitive copying paper of the present invention has been described with respect to an example in which the pressure-sensitive copying paper is folded in three in an S-shape or Z-shape, but the present invention can also be applied to the case of three-fold folding by appropriately changing the application position.

【The invention's effect】
Since the pressure-sensitive copying paper of the present invention is composed of only one sheet, there is an effect that the user side is suitable for overlay printing of variable information, which is a unique format, with a non-impact printer or the like.
When the color developer layer and the developer layer are separately applied with the fold line on the substrate as a boundary, and then folded into a S-shape or a Z-shape, the color developer and the developer are used. Therefore, there is an effect that stains due to coloring do not occur as in the case where the self-coloring layer is provided on the entire surface.
In the part where the color former layer and the transferable self color former layer on the substrate surface overlap, the color former and the color former produced by the transferable self color former react in a mixed state. The positive characters appear in the developer layer. Therefore, there is an effect that characters once copied and formed by writing are difficult to falsify.
