Title: Innovations by Rima Akanuma in Inkjet Printing Technology

Introduction

Rima Akanuma, a talented inventor based in Tokyo, Japan, has made significant contributions to the field of inkjet printing technology. With a portfolio that includes two granted patents, Rima has focused on developing innovative ink compositions and methods that enhance printing capabilities, particularly on hydrophobic fibers.

Latest Patents

Rima's latest patents include a black ink composition tailored for inkjet printing and a method for printing on hydrophobic fibers. The black ink composition features a blend of a water-soluble organic solvent, a resin emulsion, a dispersing agent, and at least four types of sublimation dyes. Notably, three of these sublimation dye types are designated as C.I. disperse yellow, C.I. disperse red, and C.I. disperse blue. Additionally, at least one dye exhibits a maximum absorption wavelength within 640 nm to less than 680 nm, as observed through visible spectral absorption when dissolved in acetone. This innovative ink set aims to improve the quality and efficiency of inkjet printing on various substrates.

In conjunction with the ink composition, Rima also developed an ink composition specifically for inkjet textile printing that incorporates a urethane resin, dispersant, and disperse dye. The proportion of urethane resin is carefully controlled to be greater than 0.035 mass % but less than 6 mass %. The accompanying method for textile printing on hydrophobic fibers employs this advanced ink composition effectively.
