  • PROCESS OF PRODUCING CAPSULE-COATED SHEETS Inventors-. Masao Kanda; Keiso Saeiki, both of Fujinomiya, Japan Assignee: Fuji Photo Film (10., Ltd., Minami- Ashigara, Japan Filed: Jan. 2, 1974 Appl. No.: 430,015
  • ABSTRACT Microcapsule coated sheets can be efficiently produced by a process wherein excess microcapsule coating composition is removed from a running base sheet by a mechanical tool which by shear force meters and levels the microcapsule coating composition, if the microcapsule coating composition has a solids content of about 20 to 80 weight percent and a viscosity of 50 to 50,000 c.p.
  • the present invention relates to a process for producing capsule-coated sheets, and more particularly it relates to a process and apparatus for applying a coating composition consisting of minute capsules onto moving support.
  • the viscosity of the coating composition in-- creases by increasing the solids content of the coating composition, so that in order to meter a predetermined quanity of coating, it is necessary to increase the wind pressure of the air jet which increases the spattering of the excess coating composition contaminating the doctor blade whereby more frequent cleaning becomes necessary.
  • the present invention overcomes the abovementioned disadvantages, and is characterized in that it uses a coating apparatus comprising a coating tool for applying a surplus amount of coating composition onto a support and a doctor blade or metering bar acting to measure the coating composition and to equalize it to thus apply a coating composition consisting of minute capsules onto a running support.
  • One object of the present invention is to provide a method and apparatus for applying a high-density, high-viscosity capsule coating composition onto a support.
  • Another object of the present invention is to provide a coating apparatus for a capsule coating composition which does not spatter the coating composition by the spraying of an air jet, whereby a continuous coating operation can be effected.
  • Still another object of the present invention is to provide a coating apparatus for a capsule coating composition which uses a small drying device, and thus the space required for installation of the machine becomes small, and therefore the costs of equipment and operation can be remarkably reduced.
  • FIGS. 1 through 4 show embodiments of apparatus appropriate for carrying out the process of the present invention.
  • FIGS. 5A, 5B, 6A and 6B are microscopic photographs showing micro-capsule coating surfaces produced in accordance with the present invention taken by scanning electron microscope FIGS. 5B and 6B are of a higher magnification than FIGS. 5A and 6A.
  • the coating apparatus known as blade coaters or metering bar coaters involve the operation of scraping off the excess coating composition on the support by pressing a mechanical tool directly on the coating composition applied on the running support.
  • These devices can be adapted to use highconcentration, high-viscosity coating composition, but the blade coater and the metering bar coater give an excessive shearing stress on the coating composition at the process of metering excessive amounts of coating composition.
  • Such apparatus is thus not used as coating apparatus for coating compositions consisting of fine capsules which are readily broden by pressure, thus air knife coaters, which have the many drawbacks mentioned above, are extensively used.
  • the inventors have found that it is possible to apply a predetermined quantity of coating composition without breaking the minute particles onto a running support despite the high shearing force exerted by blade coaters and metering bar coaters.
  • the solids content in the capsule coating composition be from about 20 to about and the viscosity be in the range of 50 to 50,000 c.p.
  • the viscosity be in the range of 50 to 50,000 c.p.
  • the present invention should not be limited thereto (all viscosities measured at 25C). It shall be understood that there is no special criticality to the exact microcapsule size selected, but those skilled in the art will appreciated such are preferably of a size, usally expressed as diameter, less than about ;1., preferably about 10 p. to about 50 11..
  • Phase separation method from aqueous solution (U.S. Patent Specification Nos. 2,800,457 and 2,800,458 with the one most generally used utilizing coacervation of hydrophilic colloid sols.
  • the capsule wall film is initially formed in the presence of a monomer of initial condensate (which is the first wall film forming substance) in an oily liquid which is to be contained therein.
  • a monomer of initial condensate which is the first wall film forming substance
  • the completed polymer to form the wall film substance of the micro-capsules is not present in the first stage.
  • a second wall film forming substance which can react with said first wall film forming substance is dissolved in a polar solvent which does not mix with the oily liquid, whereafter polymerizing the first wall film forming substance and the second wall film forming substance at the interface of the oil drops of the oily liquid and the polar solvent is conducted to form a wall film.
  • a stablilizing substance which is a solid at normal temperature, and a liquid under heat, is utilized as the capsule wall film.
  • a wax or thermoplastic resin is usually used.
  • Solid particles or liquids are emulsified and dispersed in a polymer solution which is introduced in a spray dryer. At the instant the dispersed liquid is driven out in the form of minute particle from the atomizer the substances contained therein are surrounded by the polymer.
  • the same or different kinds of compounds which produce, by mutual reaction, oilinsoluble, high-molecular substances are dissolved in an oily liquid in the presence of a low-boiling solvent or a polar liquid forming a continuous phase and a polar solvent compatible therewith, and after dispersing and emulsifying the product in the polar liquid forming the continuous phase, the system is heated to transfer the wall film forming substance onto the surface of the oil particles, whereafter the high molecular weight material forming reaction at the surface of the oil granules proceeds to form the wall film.
  • the microcapsule coating liquid obtained by the abovedescribed processes is regulated so as to have a solids content of from about to about 80 and a viscosity of 50 to 50,000 c.p. by concentration, centrifugal separation, spray drying, dilution, a combination of such processes, and if necessary, by adding a viscosity intensifier.

  • Conduit 4 can also serve as an overflowing to keep the liquid level of the liquid reservoir 3 constant.
  • the mechanism is so arranged that the running support sheet 6 which is coated by liquid pressure produced at the coating composition reservoir 3, and a predetermined coating amount is obtained'by the shearing force produced by pressing the blade 1 which forms the coter onto the support sheet 6.
  • FIG. 2 Another type of blade coater is shown in FIG. 2, and this is one type of fountain blade coater.
  • a coating composition consisting of microcapsule is supplied to a coating tool 12 at the position to be coated by applying pressure by a pump, whereby a surplus of coating composition which is formed of uniform, minute microcapsules is extruded through slit 13 of coating tool 12 under pressure, whereafter the coating liquid is applied onto running support sheet 6 held by rubber-coated backing roll 11.
  • the coating liquid over-flown from the coating tool 12 enters into a coating-composition pan l4, and is recovered,

  • blade coaters of another types such as the Flexiblade coater, the Flooded nip blade coater and the blade coater in the coating apparatus of the present invention is intended to include such devices as they are all characterized by the common operation of applying a surplus of coating composition'comprising microcapsules onto a running support sheet and pressing a blade fixed transversely to the support sheet against the coated surface of the support sheet which has been coated with coating composition, whereby the coating composition is metered and rendered of uniform thickness.
  • the coating quantity can be regulated by adjusting the shearing force applied onto the coating composition on the support sheet
  • the shearing force applied on the microcapsule constituting the coating composition must be of such a degree of force that it will not break the microcapsules.
  • the shearing force to be applied to the coating composition can be varied according to the running speed of the support sheet, the thickness and the quality of the blade material, the length of the blade, the holding angle of the blade and the hardness of the backing roll, and furthermore, by varying the solids content and the viscosity of the microcapsule coating composition.
  • the conditions which will not break the microcapsules can be determined easily in a manner known to the art.

  • the capsule coating composition scraped off by the metering bar 24 enters a liquid reservoir 21 and is recovered from delivery outlet 26.
  • a roll 27 arranged in fron of the applicator roll 22 is a backing roll which serves to bring the support sheet into contact with the applicator roll 22.
  • the roll 28 positioned at the back of the metering bar 24 serves to determine the contact angle between the support sheet and the metering bar 24.
  • Metering bar 24 can be a round bar having a diameter less than 50 mm coated with smooth, hard chromium surface, particularly a bar having a diameter between 3 and 15. Further, the metering bar is preferably wound with wire, and it is possible to change the quantity of coating by selecting the size of the wire.
  • FIG. 4 shows another type of metering bar coater, in which a coating composition of microcapsules is introduced into the liquid reservoir 32 through coating liquid feeding inlet 31 and removed via outlet 33, The coating composition is picked up by applicator roll 34 immersed in the coating composition, and by lowering a backing roll 35, the running support sheet 36 is made to contact on the applicator roll 34, transferring a surplus amount of microcapsule coating composition onto the sheet, The surplus coating composition is metered by a metering bar 38 arranged to contact the microcapsule coated surface of the support sheet while it is supported by a back up roll 37 positioned next to the applicator roll 34.
  • Metering bar 38 is preferably a round bar having a diameter less than 50 mm coated with smooth, hard chromium layer, especially a round bar having a diameter of 3 mm. Further, the metering bar is preferably wound with wire to permit an even more uniform coating and it is possible to vary the amount of coating by selecting the size of wire wound.

  • a coating tool is directly brought into contact with the coated microcapsule composition on the running support sheet, and by scraping off excess microcapsule coating composition metering and equalizing of the coated composition are effected. It is evident that an extremely large shearing force is appliedonto the microcapsule particles when compared with the metering action effected by a conventional air-knife coater used for producing capsule coated sheets.
  • the support sheet is coated with a microcapsule coating composition having incroporated therein cellulose flocks or the like, but when a blade coater is used which applies a coating composition consisting of microcapsules and meters by a shearing force generated by pressing the blade against the coated support sheet supported by a backing roll, cellulose flocks having a large particle size adhere to the blade and may produce scratches on the coating support sheet.
