Methods for forming dyed microspheres and populations of dyed microspheres

Номер: US20120035328A1
Автор: Ananda G. Lugade, Ewald Terpetschnig, Kurt D. Hoffacker
Принадлежит: Individual

Various methods for forming dyed microspheres are provided. One method includes activating a chemical structure coupled to a dye using heat or light to form a reaction intermediate in the presence of a microsphere. The reaction intermediate covalently attaches to a polymer of the microsphere thereby coupling the dye to the polymer and forming the dyed microsphere. Additional methods are provided for forming a dyed microsphere coupled to a molecule. These methods include dyeing the microspheres as described above in addition to synthesizing the molecule on an outer surface of the dyed microspheres. A population of dyed microspheres is also provided. Each of the dyed microspheres of the population includes a dye attached to a polymer of each of the dyed microspheres by a chemical structure. A coefficient of variation in dye characteristics of the population of dyed microspheres attributable to the dye is less than about 10%.

The ink of claim 6 , wherein said polymeric binder is acrylic. This application claims priority under 35 U.S.C. § 119 from U.S. Provisional Application Ser. No. 62/272,176, filed Dec. 29, 2015, which is incorporated by reference in its entirety.The present disclosure pertains to a dye-based inkjet ink and, more particularly, to a dye-based inkjet ink suitable for printing on textile.Digital printing methods such as inkjet printing are becoming increasingly important for the printing of textiles and offer a number of potential benefits over conventional printing methods such as screen printing. Digital printing eliminates the set up expense associated with screen preparation and can potentially enable cost-effective short run production. Inkjet printing furthermore allows visual effects, like infinite pattern repeat sizes, that cannot be practically achieved with a screen-printing process.One area of textile printing ideally suited to digital printing is the flag and banner market where short runs are common. However, printing of flags and banners presents unique challenges. For example, ink is printed on one side, but must penetrate the fabric so that the image is equally visible on the back (unprinted) side as on the front (printed) side. In addition, while the ink must travel through the fabric, it must not travel laterally causing blurring ...

Process For Producing Dye-Containing Heat-Curable Resin Particles

Номер: US20190010388A1
Автор: Kensaku Takanashi, Shin Nakayama
Принадлежит: KONICA MINOLTA INC

The present invention provides a method of producing dye-containing thermosetting resin particles, the method including: dispersing seed particles formed from a thermosetting resin in a dispersion medium; and polymerizing a monomer for thermosetting resin synthesis in the thus obtained dispersion in the presence of a dye and an acid catalyst. By the method of producing dye-containing thermosetting resin particles according to the present invention, dye-containing thermosetting resin particles whose particle size variation coefficient is small at, for example, 8% or less, can be produced without performing a post-treatment such as centrifugation. Therefore, when immunological observation is performed by a fluorescent labeling method using fluorescent dye-containing resin particles produced by the method of producing dye-containing thermosetting resin particles according to the present invention, a high bright spot detection accuracy can be attained.
