Definitions
- ABSTRACT A capsule-carrying sheet or web, e.g. a sheet carrying [30] Forelgn Apphcatlon Pnonty Data capsules containing a colour-reactant material for use Oct. 18, United Kingdom in a pressure.sensitive opying ystem in one surface of the sheet or web carries a coating incorpo- US.
- encapsulate for example, dyes, inks, chemical reagents, pharmaceuticals, flavourings, pesti cides, herbicides an d in fact any material which can be dissolved, suspended or otherwise constituted in or as a liquid internal phase enclosed within a capsule wall.
- the capsule serves to maintain the internal phase in its liquid, or some other converted form, at least until the internal phase is released by rupture, melting, dissolving or other removal of the capsule wall, or until the internal phase is caused to diffuse out through the capsule wall.
- a disadvantage of capsules produced by known methods is that they are not sufficiently inherently strong to prevent accidental rupture thereof, this being a particular disadvantage in pressure-sensitive copying systems where accidental rupture of capsules can result in undesirable marking of the copy sheet.
- British Patent Specification No. 1,232,347 teaches that the starch particles must be dispersed in a capsule coating layer carried on a sheet or web, and thus that the starch particles must not be dissolved in the capsules coating mix prior to coating thereof onto a sheet or web.
- the specification teaches that in order to prevent gelatinisation of the starch particles, the capsule coating mix must be at a temperature of less than 50C, preferably less'than 35C, when the starch particles are added thereto.
- the capsules and cellulose fibres are coated onto a base sheet or web in admixture with a gelatinised starch solution which is to serve as a binder between the capsules and the cellulose fibre, and the base sheet or web.
- the sheet or web produced thus carries a coating including capsules, protection for the capsules, i.e. the cellulose fibres and a binder for the capsules and the cellulose fibres, i.e. the gelatinised starch solution.
- a capsulecarrying sheet or web comprises a base sheet or web having on a surface thereof a coating comprising capsules, derived starch particles (as herein defined) as protection for the capsules, and a derived protein binder (as herein defined) for the capsules and derived starch particles.
- derived starch particles and derived protein binder are used to denote particles and binder derived from a common milled flour source by suitable treatment thereof.
- Flour e.g. wheat grains
- Flour comprises starch particles bound together by protein material, the grains of flour being known as endosperm. Milling of such flour fractures the grains into the following four parts, the pro portions of the parts obtained being dependent to some extent upon the milling conditions but to a greater extent upon the hardness of the grains:
- the invention enables the protection for the capsules (namely the starch particles) and the binder (namely the protein) to be obtained from a single source which is inexpensive and convenient to use.
- a suitable treatment of milled flour to derive the starch particles and binder for the capsule-carrying sheet or web of this invention is agitation of an aqueous suspension of the milled flour for a time dependent upon the temperature of the suspension thereby to dissolve the protein fragments, the time varying between about 1 hour for a room-temperature suspension and 102O minutes for a suspension at C.
- Caustic soda can be added to the aqueous suspension to help in solubilising the protein fragments.
- the temperature of the suspension must not be such as to cause gelatinisation of the starch particles, and thus the upper temperature limit for the suspension is about C.
- a method of producing a capsule-carrying sheet or web comprises the steps of treating milled flour by agitation of an aqueous suspension thereof to provide derived starch particles (as herein defined) and derived protein binder (as herein defined), and coatingthe derived starch particles and derived protein binder onto a base sheet or web together with capsules.
- Optimum protection for the capsules is provided by starch particles of a size between about 1 /2 and 2 times the average size of the capsules and thus it is preferable to provide a majority of derived starch particles of such size.
- Capsules presently used in pressure-sensitive copying systems are normally within the size range 320;.tm.
- milled flour can be pre-treated, for example by air classification, to remove the small size range (l0um) starch particles mentioned above, prior to treatment thereof to derive the starch particles and binder for a capsulecarrying sheet or web according to this invention.
- micro-capsules can be carried on one surface of a transfer sheet known as a CB sheet, and the co-reactant material carried on one surface of a separate record sheet, known as a CF sheet. Otherwise, the microcapsules and the co-reactant material can be carried together on the same surface of a single sheet.
- the capsules used had walls of gelatin and gum arabic enclosing an internal phase comprising the dye substances crystal violet lactone and benzoyl leuco methylene blue dissolved in a solvent including dibenzylbenzynes (as described in United Kingdom Patent Application Nos. 44474/71 and 2785/72, now cognated), and diluted with kerosene.
- a solvent including dibenzylbenzynes as described in United Kingdom Patent Application Nos. 44474/71 and 2785/72, now cognated
- many different kinds of capsules are known which could otherwise be used.
- the required weight of wheatflour was added to the preheated water while being stirred.
- the five suspensions were then made up into 17% solids coating mixes by admixture with a dispersion of the described capsules at a parts by weight ratio of capsules to 30 wheatflour.
- the coating mixes were then coated onto a 49 g/m base paper, using a pilot plant coating machine, with a coating weight of 7 g/m to give CB paper as described.
- the CB papers thus produced were then subjected to three tests, namely l a test to measure the distinctiveness of the mark produced by the paper on a standard CF paper; (2) a test to measure the resistance of the CB paper to accidental rupture of the capsules thereon; and (3) a test to measure the adhesion of the capsules and starch particles of the CB paper to the base paper thereof.
- flour of Indian com potato, sweet potato, sago, tapioca, rice, glutinous rice, glutinous corn or arrowroot.
- a process for producing a capsule-carrying sheet or web comprising a base sheet or web having on a surface thereof a coating comprising capsules, protective particles as protection for the capsules, and a binder for the capsules and the protective particles, wherein the protective particles are starch particles and the binder is a protein binder with the starch particles and the protein binder being both derived from a common milled flour source, which process comprises (a) treating milled flour to provide the starch particles and the protein binder, and (b) coating the starch particles and protein binder onto the base sheet or web together with the capsules.
- starch particles and said protein binder are derived from a flour selected from the group comprising flours of wheat, Indian corn, potato, sweet potato, sago, tapico, rice, glutinous rice, glutinous corn and arrowroot.
