  • Patent number: 11697907
    Abstract: Disclosed is a method for producing an embroidery pattern through stitching to a substrate, particularly a method for producing a colored embroidery pattern having color disposition corresponding to a complex shape or stitches, simply and at low cost. The method includes: forming an embroidery base pattern to a substrate by use of single-color embroidery thread; printing a transfer image on an intermediate recording medium having a total light transmittance Tt of 60% or higher by use of a sublimable disperse dye, the transfer image being used for dyeing the embroidery thread of the embroidery base pattern; superposing the transfer image on the embroidery base pattern, while the intermediate recording medium is positioned from the backside of a printed surface of the recording medium; and heat-pressing the intermediate recording medium from the backside of the recording medium, to thereby dye the embroidery thread of the embroidery base pattern.

  • Patent number: 8137882
    Abstract: A toner for developing electrostatic images which is obtained by melt mixing at least a binder resin and a coloring agent, forming a powder material by pulverizing the obtained mixture after cooling and removing rough particles and fine particles from the formed powder material by classification, wherein inorganic fine particles having a roundness of 1.00 to 1.30, an average of the diameter of primary particles of 0.05 to 0.45 ?m and a ratio of a standard deviation to the average of the diameter of primary particles of 0.25 or smaller are added as an external additive, and a process for producing a toner for developing electrostatic images which comprises melt mixing at least a binder resin and a coloring agent, forming a powder material by pulverizing the obtained mixture after cooling, rounding the powder material by a heat treatment and adding the above inorganic fine particles to the rounded powder material.
