Title: Kazuhiko Sakata: Innovator in Thermal Transfer Printing Technology
Introduction
Kazuhiko Sakata is a prominent inventor based in Tsukuba, Japan. He has made significant contributions to the field of thermal transfer printing, holding a total of 4 patents. His innovative work has led to advancements in printing technology, particularly in the development of dyesheets that enhance print quality and durability.
Latest Patents
Sakata's latest patents include a thermal transfer printing dyesheet that features a unique construction. This dyesheet comprises a sheet substrate with a thermal transfer dyecoat on one face and a heat-resisting slipping layer on the other. The slipping layer is characterized by a silicone resin powder with a silsesquioxane structure, combined with metal salt powders of higher fatty acids and their phosphates. This innovative design ensures superior travel, outstanding scratch resistance, and excellent storage stability without adversely affecting the dyecoat.
Another notable patent is a thermal transfer dyesheet that includes a base sheet with a thermal transfer dye layer on one surface. The opposite side features a heat-resistant backcoat formulated to minimize scratching during printing. This backcoat is created from a crosslinked reaction product of a compound with multiple polymerizable unsaturated groups, along with a slip agent that is a multivalent metal salt of a long-chain alkyl or alkylphenyl phosphate ester. The combination of these elements is crucial for achieving the desired relief from scratching.
