Title: Nobuhiro Kagota: Innovator in Pressure-Sensitive Technologies
Introduction
Nobuhiro Kagota is a prominent inventor based in Takasago, Japan. He has made significant contributions to the field of pressure-sensitive technologies, holding a total of 8 patents. His innovative work focuses on environmentally friendly materials and advanced adhesive compositions.
Latest Patents
Kagota's latest patents include a carbonless pressure-sensitive copying paper that utilizes a solvent free of unpleasant odors, making it environmentally friendly. This copying paper features a layer containing microcapsules that enclose a color former dissolved in a middle-length-chain triglyceride (MCT) solvent. The color former is either an indolylazaphthalide compound or a fluoran compound with a trifluoromethylanilino group. Additionally, the paper incorporates a specific fatty acid ester solvent and an inorganic color developer, preferably a semi-synthetic solid acid.
Another notable invention is the thermal delayed-tack adhesive composition. This composition remains non-adhesive at ordinary temperatures but becomes tacky when heated. It maintains its tackiness for an extended period, even after being separated from a heat source. The thermal delayed tack sheets created from this composition do not block or stick together, even when wound into a roll or layered upon each other. The composition consists of an aqueous resin dispersion with a polymer resin, a tackifier, and a solid plasticizer.
