| titleOfInvention | A method and apparatus for encapsulating liquids |
| abstract | A carbonless transfer paper comprises a paper or plastic backing coated with encapsulated liquid particles. The liquid may be a solution of a coloured or colour-forming substance, e.g. a dye-containing aqueous or organic carrier, a liquid which undergoes a colour-forming reaction upon exposure to air or atmospheric moisture, or one component of an azo dye forming system (to be associated with similar encapsulated particles of the second component). The capsules are rupturable by the pressure of a stylus or type-bar. The capsules may be naturally adherent to the backing or a binder may be used which may contain one component of a colour-forming system. The capsules are made by forming core particles which at least partly comprise frozen liquid, forming a dispersion of said core particles in a gaseous stream and spraying into said dispersion a solution of an encapsulating material in a solvent which is volatile below the freezing point of said liquid to coat said core particles with a continuous film of said encapsulating material. The dispersion may be a fluidised bed of the particles. The particles may be produced by coating a core of clay, silica, alumina, calcium carbonate, sodium carbonate, sodium hydroxide, sodium chloride, sodium thiocyanate, ferric chloride, ferric sulphate, crystal violet or metal powders with the liquid and then freezing. The liquid may be coloured. The encapsulating layer may be shellac, natural or synthetic wax, natural or synthetic gum, asphalt, tar, hard fat, gelatine, sugar, lacquer, varnish, cellulose nitrate, cellulose acetate, sodium silicate, gluten, starch, a methacrylate resin, polystyrene, a polyolefine, polyvinylchloride or the material sold under the Registered Trade Mark "Saran". It may be applied as a melt, or as a solution or dispersion. |
