본 발명의 가시정보기록매체에 관한 것으로서, 보다 구체적으로는, 서비스상태 등의 정보를 열기록수단에 의해 눈으로 볼 수 있도록 기록하는 것이 가능한 카드형 가시정보기록매체에 관한 것이다. 본 발명의 가시정보기록매체는, 예를들면, 각종 선불형 자기카드의 내용에 상당하는 숫자 등을 인쇄함으로써 자기적으로 기록된 내용을 눈으로 확인하기 위한 용도로서 특히 유효하다.The present invention relates to a visible information recording medium of the present invention, and more particularly, to a card type visible information recording medium capable of recording information such as a service state so as to be visible by a thermal recording means. The visible information recording medium of the present invention is particularly effective for visually confirming the contents recorded magnetically, for example, by printing a number corresponding to the contents of various prepaid magnetic cards.
선불형 자기카드가 널리 사용됨에 따라, 눈으로 확인할 수 있도록 그의 자기적으로 기록된 내용에 상당하는 문자, 숫자 등의 가시정보를 인쇄하는 요구가 증대되어 왔다. 예를들면, 선불형 카드를 복수회 사용한 경우, 사용한 경우, 사용자가 매회마다의 요금이나 서비스내용 그리고 카드내에 기록된 채무의 명확한 총계를 눈으로 확인할 수 있다면 상당히 편리하다. 이러한 요구에 대처하기 위해서, 열기록헤드를 사용하여 각종 정보를 기록할 수 있는 감열층을 구비한 자기카드가 개발되었다(예를들면, 일본국 특개평 2-62287호).As prepaid magnetic cards have been widely used, there has been an increasing demand for printing visible information such as letters and numbers corresponding to their magnetically recorded contents for visual confirmation. For example, when a prepaid card is used multiple times, it is quite convenient if the user can visually check the rate or service content of each time and the definite amount of debt recorded in the card. In order to cope with such a demand, a magnetic card having a heat sensitive layer capable of recording various types of information using a thermal recording head has been developed (for example, Japanese Patent Laid-Open No. 2-62287).
이러한 유형의 종래의 자기카드는, 플라스틱기판중의 한쪽면에 콘트라스트향상층, 열층, 얇은 금속층 및 보호층을 순차 형성하고, 이 보호층의 표면과 열기록부의 열헤드를 접촉시켜 열기록을 수행하고 있다. 열헤드에 의해 부여된 열은 보호층 및 제2열층을 경유해서 얇은 금속층으로 전달되어 그 일부를 용융시켜 소정부위에 구멍을 형성한다. 콘트라스트향상층은 상기 얇은 금속층 아래에 위치되어 있으므로, 상기 구멍부를 통해서 명료하게 볼 수 있어, 구멍이 없는 부분과의 명암대비에 의해 각 구멍에 대응하는 문자, 숫자 등을 눈으로 볼 수 있다.In the conventional magnetic card of this type, a contrast enhancement layer, a thermal layer, a thin metal layer, and a protective layer are sequentially formed on one side of a plastic substrate, and the surface of the protective layer is brought into contact with the thermal head of the thermal recording section to perform thermal recording. Doing. The heat imparted by the heat head is transferred to the thin metal layer via the protective layer and the second heat layer to melt a portion thereof to form a hole in a predetermined portion. Since the contrast enhancement layer is located under the thin metal layer, it can be clearly seen through the hole portion, so that letters, numbers, etc. corresponding to each hole can be visually seen by contrast with the portion without the hole.
상기 종래의 가시정보기록매체는, 서비스상태 등의 정보를 가시적으로 기록할 시간 동안 있다는 점에서 편리하나, 임시정보나 제기록을 요하는 정보가 기록된 경우, 일단 기록된 것을 지우고, 새로운 정보를 다른 영역에 기록해야만 한다. 그러나, 기록용으로 사용될 수 있는 면적은 제한되어 있으므로, 재기록회수가 제한된다.The conventional visible information recording medium is convenient in that it is for a time to visually record information such as service status, but when temporary information or information requiring recording is recorded, the recorded information is erased once and new information is deleted. You must record in another area. However, since the area that can be used for recording is limited, the number of times of rewriting is limited.
그러므로, 재기록할 수 없는 ID정도 등의 정보 및 서비스상태에 의존하여 기록가능한 정보를 기록할 수 있는 기록매체의 개발이 요망되고 있다.Therefore, development of a recording medium capable of recording recordable information in dependence on information such as ID degree that cannot be rewritten and service status is desired.

In case of cooling, transparency is lowered according to heating history so that it shows low transparency. The reversible thermal recording layer and made of a material, the reversible visible information recording medium consisting of a protective layer for protecting the outer surface of the thermal recording layer is provided.

It consists of. When such a heating information recording medium is applied to, for example, a prepaid magnetic card, information such as service failure is recorded on the reversible thermal recording layer, and when it is used, a code indicating that it is unusable is recorded and used on the irreversible thermal recording layer. Any completed card can be prevented from being used illegally.
본 발명의 바람직한 실시예에 있어서, 가시정보기록매체는 자기카드형이어도 되며, 콘트라스트향상층이 기능을 지닌 자성층과, 열가용성층과, 가역성 열기록층과, 보호층이 순차 형성된 구성을 지닌다. 가역성 열기록층상의 열기록은, 보호층의 표면을 열기록부의 열헤드와 접촉시킴으로써 수행된다. 열헤드에 의해 부여된 열은, 가역성 열기록층용의 보호층의 광투명도를 변화시켜, 보호층과 열이 부여되지 않은 부분에서의 광투명도의 차이에 따라 소망의 정보를 가시적으로 기록한다.In a preferred embodiment of the present invention, the visible information recording medium may be a magnetic card type, and has a structure in which a magnetic enhancement layer having a function of a contrast enhancement layer, a heat-soluble layer, a reversible thermal recording layer, and a protective layer are sequentially formed. Thermal recording on the reversible thermal recording layer is performed by contacting the surface of the protective layer with the thermal head of the thermal recording portion. The heat provided by the heat head changes the light transparency of the protective layer for the reversible heat recording layer, and visually records desired information in accordance with the difference in the light transparency in the portion where the protective layer and the heat are not applied.
얇은 금속층 근방에 형성된 열가용성층은, 그 위에 비가역적으로 정보를 기록하기 위하여 얇은 금속층의 일부의 용융시 용융된 금속을 분산하거나 흡수하는 기능을 가지므로, 이 층은 얇은 금속층 근방에 있는 경우, 그 위나 아래에 또는 양쪽에 설치해도 되는 것은 물론이다.The heat-soluble layer formed near the thin metal layer has a function of dispersing or absorbing molten metal upon melting of a portion of the thin metal layer in order to irreversibly record information thereon, so that when the layer is near the thin metal layer, Of course, you may install above or below, or both.
이러한 가역성 열기록층은, 포화 또는 불포화 지방산이나 그의 유도체의 혼합물을 비닐계 중합체나 폴리에스테르 등의 중합체로 이루어진 혼합물에 적당한 두께로 도포함으로써 형성할 수 있다. 이러한 가열성 열기록층은 외부로부터 열을 가하면, 투명한 상태로부터 거의 불투명한 흐린 상태까지의 범위내에서 그의 광투명도가 변하여 냉각한 후 그의 상태를 유지한다.Such a reversible thermal recording layer can be formed by applying a mixture of saturated or unsaturated fatty acids or derivatives thereof to a mixture made of a polymer such as a vinyl polymer or a polyester in an appropriate thickness. Such a heat-resistant recording layer maintains its state after cooling by changing its light transparency within a range from a transparent state to an almost opaque cloudy state when heat is applied from the outside.
따라서, 본 발명에 의한 가시정보기록매체는 가시정보기록매체로서의 각종 용도에 대처하도록 재기록가능한 정보 및 재기록불가능한 정보를 동일 또는 상이한 임의의 영역상에 기록할 수 있다.Therefore, the visible information recording medium according to the present invention can record rewritable information and non-rewritable information on any area that are the same or different so as to cope with various uses as the visible information recording medium.
이하, 첨부도면을 참조하여 본 발명의 바람직한 실시예에 대해서 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.
먼저, 제1도는 본 발명에 적용가능한 대표적인 가역성 열기록층의 광투명도 및 가열온도간의 관계를 도시한 도면이다. 가역성 열기록층을 제1영역내의 온도(T1 내지 T2)로 가열한 후 T0 이하의 온도로 냉각하면, 이 층은 그의 최고 투명도를 지닌다. 다음에, 이 층을 T3 보다 높은, 제2영역내의 온도까지 가열한 후 T3 이하의 온도로 냉각하면, 투명도가 가장 낮은 흐린상태로 된다. 또, T0 내지 T1영역은 온도 또는 T2 내지 T3영역의 온도로 가열한 후, T0 이하로 냉각하면, 가열온도에 따라 변하는 각종 투명도를 나타낸다.First, FIG. 1 is a diagram showing the relationship between light transparency and heating temperature of a typical reversible thermal recording layer applicable to the present invention. When the reversible heat recording layer is heated to a temperature T1 to T2 in the first region and then cooled to a temperature below T0, this layer has its highest transparency. Next, the layer is heated to a temperature in the second region higher than T3 and then cooled to a temperature equal to or lower than T3, resulting in a hazy state with the lowest transparency. The T0 to T1 regions exhibit various transparency changes depending on the heating temperature when the T0 to T1 region is heated to the temperature or the temperature of the T2 to T3 region and then cooled to T0 or lower.
즉, 이 가역성 열기록층은 그의 가열이력에 대응하는 투명도 또는 불투명도를 지닌다. 여기에서, 온도 T0는 기록매체가 통상 서비스상태에 노출되는 최고온도보다 다소 높은 온도이다. 이 투명도의 변화는 거의 완전히 가역적이며, 가열 및 냉각회수를 반복할 때마다 소망의 투명도를 얻을 수 있다.That is, this reversible heat recording layer has transparency or opacity corresponding to its heating history. Here, the temperature T0 is a temperature slightly higher than the highest temperature at which the recording medium is normally exposed to service. This change in transparency is almost completely reversible, and the desired transparency can be obtained each time the heating and cooling recovery is repeated.
이러한 가역성 열기록층을 형성하는 재료는, 수직매트릭스와 그 안에 분산된 저분자량의 유기화합물을 함유한다. 이러한 혼합물에 있어서, 수지매트릭스로서는, 폴리염화비닐중합체, 그리고 염화비닐과 염화비닐리덴, 비닐아세테이트, 비닐알코올, 말레산, 아크릴산에스테르, 아크릴로니트릴 및 폴리에스테르 중의 1종류 이상과의 공중합체가 적합하다.The material for forming such a reversible thermal recording layer contains a vertical matrix and a low molecular weight organic compound dispersed therein. In such a mixture, as the resin matrix, a polyvinyl chloride polymer and a copolymer of vinyl chloride and one or more of vinylidene chloride, vinyl acetate, vinyl alcohol, maleic acid, acrylic acid ester, acrylonitrile and polyester are suitable. Do.
특히, 상기 수지매트릭스로서는, 미합중국의 코넥티컷주의 유니온카바이드사제품인 상품명 VTHH로 시판되고 있는 염화비닐/비닐아세테이트 공중합체가 적합하다. 또한, 이들 수지성분내에 혼합된 저분자량의 유기화합물로서는, 탄소원자수가 약 10~30개인 포화 또는 불포화 지방산이나 그들의 염, 에스테르, 아미드로부터 선택된다. 가장 적합한 저분자량의 유기화합물은 스테아린산, 올레산 등의 지방산이다. 사용되는 저분자량의 유기화합물을 선택함으로써 온도 T1, T2 및 T3를 어느 정도 자유롭게 조절할 수 있다.In particular, as the resin matrix, a vinyl chloride / vinylacetate copolymer commercially available under the trade name VTHH manufactured by Union Carbide Co. of the United States of America is suitable. Further, the low molecular weight organic compound mixed in these resin components is selected from saturated or unsaturated fatty acids having about 10 to 30 carbon atoms, their salts, esters, and amides. Most suitable low molecular weight organic compounds are fatty acids such as stearic acid and oleic acid. By selecting the low molecular weight organic compound used, the temperatures T1, T2 and T3 can be freely controlled to some extent.
상기 혼합물은 필요시 염료나 안료를 함유해도 된다.The mixture may contain a dye or a pigment if necessary.
한편, 비가역성 정보가 기록된 경우, 열기록부의 열헤드는 보호층의 표면과 접촉하여 얇은 금속층을 통해서 부분적으로 구멍을 형성한다. 콘트라스트향상층은 상기 얇은 금속층 아래에 위치되어 있기 때문에, 이 구멍부에서 투명하게 보이므로, 상기 구멍부와 구멍이 없는 부분간의 콘트라스트에 의해, 구멍에 상당하는 문자, 숫자 등을 뚜렷하게 볼 수 있다. 이 경우, 가열온도 T4는, 가역성 열기록층의 투명도를 변화시키기 위하여 적용된 최대온도 T3 보다 명백하게 높다.On the other hand, when irreversible information is recorded, the thermal head of the thermal recording portion contacts the surface of the protective layer to form a hole partially through the thin metal layer. Since the contrast enhancement layer is located below the thin metal layer, it is transparent at this hole portion, so that the letter, number, etc. corresponding to the hole can be clearly seen by the contrast between the hole portion and the portion without the hole. In this case, the heating temperature T4 is obviously higher than the maximum temperature T3 applied to change the transparency of the reversible thermal recording layer.
따라서, 본 발명의 기록매체는, 통상 용도에서는 가역성 열기록층의 투명도의 변화를 사용하여 기록함으로써 또한, 정보의 재기록을 요하지 않거나 원하지 않을 경우 비가역성 열기록층에 정보를 기록함으로써, 각종 기록유형에 적용가능하다.Therefore, the recording medium of the present invention can be recorded in various types of recording by recording by using a change in the transparency of the reversible thermal recording layer in normal use, and by recording the information in the irreversible thermal recording layer when information is not required or desired. Applicable.
