- 4 and 5 are hot-melt paints containing a colorant.
- F. A layer coated with spots only on essential parts
- 5 ' is a layer coated completely
- 6 is a layer having porous micro-absorbing pores composed of microphone ⁇ -capsule, fine powder, and binder It is.
- BACKGROUND ART A pressure-sensitive recording material in which two color components, which have been widely used in the past, are coated on separate support surfaces, is of the type shown in FIG.
- one of the color components is microencapsulated (2) and covers the lower surface of the upper support (1), and the other color component is formed as a coating layer (3) on the upper surface of the lower support (1).
- the liquid in the micro force busel (2) flows out and the coating layer
- the upper support and the lower support were overlapped and cut. ) Then, coloring contamination occurs in the area where the pressure is applied.
- the pressure-sensitive recording paper coated with a microcapsule (2) containing a color component is coated on the upper and lower surface of the support.
- spot coating of microcapsules is practically difficult because of the difficulty in obtaining a strong force busel that can withstand spot coating and wrinkling of the support after coating due to the Tf coating. is there.
- spot coating is applied to the lower surface of the upper support (1) as shown in Fig. 3 using a so-called hot melt ink in which the coloring component is dispersed in hot-melt hot melt wax. It has been proposed to form a three-spot transferable coating layer (4). In the case of this type, the color components contained in the transferable coating layer (4) and the receptive coating layer (3) must not be wrapped by other components (eg, box, binder, etc.). However, when the upper support and the lower support are handled in an overlapping manner, coloring contamination occurs due to unexpected external force. Also.
- the transferable coating layer (4) is transferred to the receptive coating layer (3) by a fool U, and the receptive layer (3) is the transferable coating layer (4)
- the color development speed and color density of the receptive coating layer are often reduced.
- the present invention provides
- the reason coating layer is a layer having porous fine absorption pores composed of a microphone mouth capsule containing the other coloring component, a fine powder, and a binder.
- FIG. 4 illustrates the present invention, wherein the transferable coating layer (5) is
- FIG. 5 shows a state in which a transferable coating layer ( 5 ′) is entirely coated on the lower surface of the upper support ( ⁇ ).
- (6) is a layer having micro-capsules, fine powder, and a binder and having porous fine absorption pores, which is provided on the upper surface of the lower support.
- the pressure-sensitive recording paper has one color component as a liquid.
- the liquid in the capsule is transferred to the receiving surface to form a color.
- the entire liquid in the force cell does not necessarily transfer to the receiving surface, and remains on the transfer surface without contributing to color formation.
- the microcapsules are
- the color components in the capsule are effectively changed to colored substances, and an image is formed as it is on the receiving surface, so that both the coloring speed and the density are increased. For the same reason, it is often necessary to incorporate a large amount of a coloring component.
- the first feature of the present invention is that the microcapsule containing one color component is contained in the receptive coating layer.
- a second feature of the present invention is to use a hot-melt paint containing a coloring component in the transferable coating layer.
- hot-melt paints are so-called hot-melt inks or hot-melt paints. They are easy to apply by sbot coating and require only cooling after coating and do not require drying. This is advantageous in that the coating speed can be increased, but this is
- the receptive coating layer has a structure having porous fine absorption pores composed of a microcapsule, a fine powder, and a binder, and the liquid exposed during pressurization is instantaneously and completely filled into the pores. Absorb. Due to this, the hot-melt type paint is completely transferred, and the liquid does not reversely transfer.
- the structure having the porous fine absorption pores also has a protective effect against external force of the microphone ⁇ capsule.
- the pore volume of the capsule should be larger than the total volume of the liquid in the force vessel.
- Appropriate conditions must be selected according to the size, amount of binder, particle shape of fine powder, particle size and distribution of grain production.
- the following table is an experimental example showing the relationship between the compounding ratio of capsules, fine powders and binders and their functions when forming an acceptable coating layer.
- a hot-melt paint containing 30% of Shilton clay manufactured by Mizusawa Chemical was used as the transferable coating layer.
- the diameter of the capillary is preferably as large as possible.
- the diameter of the porous fine absorption pores existing in the layer is large.
- the size of the microcapsule is usually about 1 to 10 microns, and the body content is small, so if the pore diameter in the vicinity is 9 large, it will not move at all along the pore. That is, in the state of being absorbed. Therefore, the diameter of the porous fine absorption pores is about 10 micron. To increase the liquid absorption capacity, the total volume of the pores must be large.
- microcapsules are spherical when dispersed in a liquid, but close to the continuous phase when dried as a coating and do not leave microcapsule gaps. In the meantime, powder and fiber fine powder are mixed so that a fine space remains after the dry operation.
- the total volume of space of the porous micro-absorbing pores that gives such an effect is irrelevant to the amount of fine powder to be blended.3) It is directly related to the amount of binder to be blended, Occasionally decreases, increases with small amounts.
- the support has absorbency, the binder absorbed in the coating for the coating layer is absorbed and the amount of the binder remaining in the dried coating layer is changed. Sex also affects the total volume of space. Therefore, in the paint formulation examples in the above table, fine paper of rice weighed 43 was used as the support.
- OMPI Use; r This is an example in which precipitated calcium carbonate and polyvinyl alcohol are blended in the microcapsule, but depending on the material used for convenience, depending on the selection of the macrocapsule, fine powder or binder, this is They do not always show the same results. Usually, the combined ratio of each component in the coating layer is
- the proportion of the fine powder and the binder used must be appropriately selected within the above range so that the desired volume of porous fine absorption pores is formed.
- the amount of the fine powder and the binder used is appropriate so that the total amount of the liquid in the microphone ⁇ capsule does not exceed the total space volume of the porous fine absorption pores generated in the receptive coating layer. Need to be chosen.
- the support in the present invention is mainly paper.
- the receptive coating layer is provided with a liquid absorbing property
- non-absorbing materials such as plastic films, metal foils and the like can be used, and the support material is not particularly limited. Absent.
- a substance which is highly volatile at around 100 ° C or a liquid at room temperature is preferably triphenylmethane.
- a combination of a ferric fatty acid salt with a higher alcohol ester of gallic acid, and a combination of a vanadium compound such as steryl l-methylammonium vanadate with a higher alcohol ester of gallic acid may be used. In some cases], these pairs can be mixed and used.
- the fine powder in the present invention refers to various inorganic and organic white pigments, starch particles, wood fiber powder, and the like. . This is because even if the coloring component is in the microcapsule, it does not necessarily adhere to the outer wall of the capsule. For example, for capsules such as crystal violet lactones, it is desirable to use a compound that does not show coloration such as calcium carbonate and aluminum hydroxide. ⁇
- the particle shape, particle size, and particle size distribution are related to the formation of porous micro-absorbing pores, and are factors that determine the speed and amount of liquid absorbed in the capsule. In general, it is difficult to show numerical values, but particles
- the thing passing through the 300 mesh is preferable.
- the binder natural and synthetic polymers which do not cause coloring and coloring are used. Since the binder content is an important factor in the formation of the porous fine absorption pores, the calculated value of the residual space when the sphere is packed in a box, the particle shape, particle size, Taking into account the particle size distribution, etc., determine the balance with the amount of the capsules mixed.
- Hot-melt paints are non-transferable, so they are primed before coating! It is desirable to keep it.
- the undercoating agent as described above, the polymer used as the binder is used, and one having a good sealing effect is selected.
- Materials other than the coloring component of the hot-melt paint include high-melting natural waxes such as carnauba wax, candelilla wax, and montane wax, oils and fats, hardened oils, higher fatty acids, their polyvalent metal salts, and petroleum. Based waxes and other non-volatile high melting point materials are used. In some cases, a small amount of a non-volatile solvent is added, and a stabilizer such as an antioxidant or an ultraviolet inhibitor is added as necessary.
- the pressure-sensitive recording material of the present invention can be used as a pressure-sensitive recording form by laminating a plurality of the sheets. '' Best mode for carrying out the invention
- Microphone containing colorless dye Create a capsule as follows.
- the formulation (parts by weight) of the paint for the acceptable coating layer is as follows! ).
- an iron-based microphone mouth capsule was prepared as follows. That is, ferric ferric acid 80 mixed with coconut oil was dissolved in oxyethylene lauryl ether (Matsumoto Kosan, Ryokutinol) to obtain 100000 ⁇ , which was converted into micro force.
- oxyethylene lauryl ether Matsumoto Kosan, Ryokutinol
- a coating for an acceptable coating layer was also prepared according to Example 1.
- composition (parts by weight) of the hot-melt paint for the transferable coating layer opposed thereto was 3 as shown below.
- Example 1 when the coated paper obtained in a manner similar to that of Example 1 was printed over .10 sheets, the color developing speed was slightly inferior to that of Example 1], but a black image with good light resistance was obtained. ,
