  • Patent number: 11091661
    Abstract: A method for preparing a large-area structural chromogenic pattern by ink-jet printing, a structural chromogenic pattern obtained by the method, and an anti-counterfeiting method based on a structural color change. A dispersion liquid containing mono-disperse colloidal microspheres with high index of refraction is printed onto a piece of paper by using an ink-jet printer, and nano-microspheres are arranged and assembled on the paper to obtain a micro-structure having the features of being ordered from a short distance and disordered from a long distance. A pretty structural color can be observed by means of the interaction of the structure with light, thus displaying a pattern, changing the angle of observation, changing the brightness of the structural color, and hiding and displaying the pattern. The method is simple and convenient, is widely applicable, and can achieve the preparation and anti-counterfeiting of a large-area structural color without external stimulation.

  • Patent number: 10519334
    Abstract: Water-based stains comprise or consist essentially of a polysaccharide resin and a crosslinking agent such as an isocyanate. Upon evaporation of water, the polysaccharide undergoes crosslinking with the isocyanate component, developing water resistance so that it will not redissolve upon application of a water-based or oil-based clearcoat; as a result, lifting is minimized after a drying time of, e.g., two to six hours.

  • Patent number: 10259953
    Abstract: An ink composition and an adhesion promoter are provided. The adhesion promoter is suitable for production while remaining the stronger adhesion. The adhesion promoter is formed by the reaction of at least one alpha hydroxy acid and at least one alpha hydroxy acid ester with the metal alkoxide. More specifically, by combining the renewable and green alpha hydroxy acid and safer plasticizing alpha hydroxy acid ester as reagent to react with the metal alkoxide, the eco-friendly and non-toxic adhesion promoter with superior adhesion for use in ink composition can be obtained. The ink composition includes the adhesion promoter, a pigment, a polymeric binder, and a solvent for the polymeric binder. The ink composition is odorless and colorless, and shows good wet crinkle resistance. Especially, the ink composition is suitable for printing on the food package.

  • Publication number: 20040069184
    Abstract: A marking composition is disclosed for placing a temporarily visible mark on a surface. The composition includes a paint base and a pigmented colorant. The pigmented colorant is dispersed within the paint base, and has characteristics that cause the mark to progressively become substantially invisible upon exposure to UV light. Additives, such as UV absorbers and anti-oxidants may be included to alter the rate at which the mark becomes invisible. The pigmented colorant may be a dispersion of dyed melamine-toluenesulfonamide-formaldehyde polymer in a mixture of alkyl based resins and aliphatic hydrocarbons. The colorant may be about 2 to 30 parts by weight of the composition. In one embodiment, the pigmented colorant is a Special Fugitive Colorant, with a color selected from the group consisting of: Special Fugitive Yellow Dispersion, No. 121M6669; Special Fugitive Orange Dispersion, No. 121M6665; Special Fugitive Red Dispersion, No. 121M6850; Special Fugitive Red Dispersion; No.

  • Publication number: 20040020407
    Abstract: The invention relates to an ink set for ink jet recording comprising at least one “resin-containing pigment ink containing water and a pigment made dispersible in water with a resin” and at least one “self-dispersion type pigment ink containing water and a pigment dispersible in water without a dispersing agent”, wherein the ink set is constituted so that the at least one resin-containing pigment ink and the at least one self-dispersion type pigment ink correspond to each other in terms of hue. Also disclosed is an ink jet recording process for conducting ink jet recording using the ink set described above, wherein the resin-containing pigment ink contained in the ink set is used for paper exclusive to ink jet recording, and the self-dispersion type pigment ink contained in the ink set is used for plain paper.

  • Patent number: 6645280
    Abstract: The present invention provides a jet ink composition suitable for printing watermarks on paper substrates. The jet ink composition comprises a solvent and a translucentizing agent. An example of a translucentizing agent is sucrose acetate isobutyrate. The present invention further provides a method of ink jet printing watermark on an object comprising projecting a stream of droplets of the ink composition and controlling the direction of the stream so that the droplets form the watermark on the object. The method of the present invention has the advantage that it provides high speed watermarking capability. The method provides a further advantage that it is economical in changing the design of watermarks. The method is versatile and allows changes in the design of watermarks to be incorporated readily.

  • Publication number: 20030096056
    Abstract: An ink for a display panel effective in reducing the uneven adhesion of the ink is applied by an ink application apparatus using an inkjet method to form a structural layer (e.g. reflective layer, phosphor layer) of a display panel such as a plasma display panel. The ink is delivered through a nozzle of the ink application apparatus and includes a powder material used in forming the structural layer, water or a water-miscible solvent, a binder formed from a water-soluble resin, and a plasticizer. The flexibility retained by the ink, even after the ink is applied, allows for leveling of the applied ink to occur and uneven adhesion to be reduced as a result.

  • Patent number: 6551392
    Abstract: A pattern-transferring film having a print pattern provided on an upper surface thereof is floated on a liquid surface within a transferring bath and an objective body is immersed into a liquid within the transferring bath together with the pattern transferring film under a liquid pressure so as to transfer the print pattern onto the objective body. An ink set of at least blue, yellow and red inks is used for printing the pattern on the pattern-transferring film. Each of the printing inks comprises at least a resin ingredient and a pigment including color pigments. The color pigment for the blue ink is a phthalocyanine blue, the color pigment for the yellow ink is an isoindolinone yellow and the color pigment for the red ink is a quinacridone red. The ink set may include one or both of a white ink and a black ink. The color pigment for the white ink is a titanium white and the color pigment for the black ink is a carbon black.
