発色型記録シートに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recording sheet capable of performing multicolor recording, and more specifically, recording images of different hues can be obtained by using light and pressure. This relates to a self-coloring recording sheet.

ることはできない。 Among various recording methods, pressure-sensitive recording paper that uses pressure is one that can be easily implemented. In this method, a colored recorded image is obtained when a reactant and a co-reactant come into contact and react, and one or both are isolated from each other with microcapsules, etc., and the pen pressure,
It is designed so that the microcapsules are destroyed by pressure such as type pressure and come into contact with each other. Although the hue of the colored image on pressure-sensitive recording paper can be changed arbitrarily by mixing various reactants, such as electron-donating compounds, depending on suitability for diazo copying, etc., the resulting colored image has a single hue. limited.
This is because microcapsules containing reactants used in pressure-sensitive recording paper are uniformly coated over the entire back surface of the support, and it is not possible to record by partially changing the hue.
一方、伝標等で異なつた色相で記録したい場合

くつかの方法が提案されている。 On the other hand, there are many cases where it is desired to record in different hues, such as traditional symbols, and for this reason several methods have been proposed for performing multicolor recording.

紙としては不向である。 Japanese Patent Publication No. 55-2356 discloses that a number of microcapsules containing different reactants, etc., whose breaking strength is changed in stages depending on the pressure, are mixed and coated on a support to reduce the pressure. It has been shown that by varying the extent, recorded images of different hues can be obtained on a support coated with the co-reactant.
However, it is very difficult to control the film strength or particle size of the microcapsules during production because the breaking strength of the microcapsules changes, and it is actually difficult to change the pressure of the pen and write at a constant pressure when recording. This is extremely difficult and is not suitable for general recording paper.

は得られない。 Japanese Patent Publication No. 48-4053 discloses that recorded images of different hues can be created by coating a phosphoric acid solution or the like on a support containing a co-reactant in areas where the color development hue is desired and modifying the co-reactant. However, since the reactants are the same, the difference in hue is small, and the stability of the area coated with a phosphoric acid solution or the like is poor over time. Japanese Patent Publication No. 51-39565 discloses an example in which the color development specificity of a co-reactant to a reactant is utilized. That is, a sheet in which various microcapsules encapsulating different reactants are coated at different locations on the back surface of a support, and a sheet in which three types of co-reactants are coated on the surface of the support in a single layer or a laminated layer are stacked. A method for obtaining multicolor records by applying pressure together was shown, and was published in Japanese Patent Application Laid-Open No. 1983-
Publication No. 95592 discloses a sheet in which microcapsules containing a solvent are coated on the back side of a support, and a sheet in which mixtures of reactants and co-reactants are partially printed on the surface of the support in different combinations. The method of overlapping and applying pressure was also developed in 1982.
Publication No. 39814 describes a sheet coated with microcapsules encapsulating a co-reactant on the back side and a sheet coated on the surface with a reactant that develops a different color when in contact with the co-reactant. A method of pressing is shown. However, in all of these methods, a recorded image having different hues can only be obtained in certain predetermined areas by performing partial printing or partial processing in advance.
また、これらは必ず反応体を含むシートと共反

が多くなる。 In addition, these methods require a combination of a sheet containing a reactant and a sheet containing a co-reactant, which is inconvenient. In fact, if you want to obtain a recorded image with different hues after recording once, you may want to be able to obtain a multicolored recorded image by writing freely on any part rather than a limited part. There will be more.

た。 The present inventors conducted research on a recording sheet that can obtain recorded images of different hues in arbitrary parts with a single sheet, and found that a microorganism containing a photocurable resin and a reactant that develops color when it comes into contact with a co-reactant. Capsules, microcapsules containing a high boiling point organic solvent and a reactant that develops a color different from the reactant, and a dispersion of a co-reactant or microcapsules containing the co-reactant are mixed and coated on the same surface of a support. By doing this, the desired self-coloring recording sheet was obtained.
本発明についてさらに詳しく説明する。 The present invention will be explained in more detail.

上に得るものである。 The self-coloring recording sheet of the present invention includes photocurable microcapsules mainly containing a photocurable resin and a reactant, and a reactant that develops a color different from the reactant encapsulated in the photocurable microcapsules and a high boiling point organic solvent. Ordinary microcapsules encapsulating the reactant and a co-reactant that reacts with the reactant to produce a colored substance are mixed as fine solids or encapsulated in ordinary microcapsules, and the co-reactant is mixed with the same support. It is coated on a surface and uses pressure and light to obtain multicolor recording on a single recording sheet.
さらに圧力と光を用いる時、圧力を加えた後に
露光する場合と露光した後に圧力を加える場合が
あり、それぞれ異なつた用途に用いられる。 Furthermore, when using pressure and light, there are cases in which exposure is applied after applying pressure, and cases in which pressure is applied after exposure, and each is used for different purposes.

応体と接触し、各反応体に特有の異なつた色相の
発色が同一部分で生じ混色として該記録シート上
に記録像が得られる。 In the case of exposure after applying pressure such as pen pressure, it can be used in the same manner as general self-coloring pressure-sensitive recording paper. That is, when the self-coloring recording sheet according to the present invention is applied directly to the coated surface or when it is placed over plain paper and pressure is applied from the plain paper side with a pencil, ballpoint pen, typewriter, etc., the photocurable microcapsules on the recording sheet and the normal The microcapsules are destroyed at the same time, and two or more reactants contained in each microcapsule are leached out and come into contact with nearby co-reactants, resulting in the same color development with different hues specific to each reactant. A recorded image is obtained on the recording sheet as color mixture.

像が得られる。 Furthermore, if you want to record in a different hue in areas other than the recording area, when the coated surface of the recording sheet is irradiated with light, the light passes through the walls of the photocurable microcapsules and hardens the photocurable resin contained therein. Since the microcapsules are changed into a strong resin, they become rigid microcapsules and no longer break even under pressure. On the other hand, normal microcapsules are not affected in any way, so if you press the desired part directly on the recording sheet with the recorded image or by overlaying plain paper etc., only the normal microcapsules will be destroyed and the encapsulated parts will be destroyed. recorded as a single hue based on the reactants present. In this way, a multicolored recorded image is obtained.

文字が地肌とは異なつた色相で得られる。 That is, the self-coloring recording sheet of the present invention and the original are superimposed. At this time, if the document support is made of a material that easily transmits light, especially ultraviolet rays, stack the document side so that the coated side of the recording sheet and the side of the document that is not written or printed, that is, the back side, are facing each other. More exposure. In addition, if the document support is difficult for light to pass through, such as a book, use a transparent or nearly transparent support to stack the recording sheet so that the uncoated surface and the written or printed surface of the document face each other. Exposure is performed from the recording sheet side. It is desirable to adjust the exposure time depending on the combination of the recording sheet and the original. When exposed to light, the written or printed designs and characters on the manuscript absorb light and the recording sheet is not exposed to light, but other areas become exposed due to the transmission or reflection of light, and the photocurable type coated on these areas The contents of the microcapsules harden. When the recording sheet after exposure is pressurized with a roll, etc., both the photocurable microcapsules and the normal microcapsules corresponding to the designs and characters of the original are destroyed, and the reactants that are part of the inclusions are leached out. When it comes into contact with the nearby co-reactant, a colored image is obtained. This colored image is caused by reactants that are encapsulated in two types of microcapsules and develop colors of different hues, and is shown as a mixed color. On the other hand, in the exposed area, the photocurable microcapsules are not destroyed, but only the normal microcapsules are destroyed, so a colored image of a single hue is obtained. In this way, the recording sheet has the same design as the original on the background of a single hue.
Characters are obtained with a different hue from the background.
