Title: Michio Fujisawa and Transfer Printing

Introduction

Michio Fujisawa is an inventor associated with Otsu, Japan, and Toyo Boseki Kabushiki Kaisha. His recorded patent concerns a transfer-printing method that uses a specially formulated release layer to apply a printed pattern to an article.

Latest Patents

Fujisawa’s listed patent is titled “Transfer printing.” The method forms a release layer on a temporary support and prints a pattern onto that layer using ink containing coloring matter. The printed transfer sheet is placed against the article, and the combined materials are heated under pressure to transfer the release layer and pattern. After the coloring matter is fixed to the article, soaping removes the release layer.

The patent specifies a release layer containing thermoplastic polymers with film-forming properties and solubility in water or alkaline water, as well as in organic solvents. It also includes plasticizers with melting points between 30°C and 120°C, selected from water- or alkaline-water-soluble oxycarboxylic acids or their derivatives. Fujisawa is associated with 1 patent.

Career Highlights

Fujisawa’s documented inventive work focuses on improving the transfer-printing process through the composition and removal properties of the release layer. The approach combines pattern transfer, heat and pressure, color fixation, and subsequent removal of the layer.

Collaborations

Fujisawa is associated with Toyo Boseki Kabushiki Kaisha. His listed coworkers include Shuzo Sawada and Hideo Kato.

Conclusion

Michio Fujisawa’s recorded patent describes a transfer-printing technique designed to transfer patterns efficiently and remove the release layer after color fixation.
