According to GlobalData’s company profile on Oji, Incontinence monitoring sensors was a key innovation area identified from patents. Oji's grant share as of June 2024 was 22%. Grant share is based on the ratio of number of grants to total number of patents.
The granted patent US11993095B2 describes a heat-sensitive recording material designed for improved performance in recording applications. The material consists of a layered structure featuring an undercoat layer and a heat-sensitive recording layer, both applied to a support. The undercoat layer is formulated with hollow plastic particles and a binder, while the heat-sensitive recording layer incorporates a leuco dye and a developer. Notably, the heat-sensitive recording material exhibits an elastic modulus of 200 N/mm² or less, as determined by a nanoindentation method. The undercoat layer specifically includes hollow plastic particles with an average diameter of 5.0 µm or more, constituting 30 mass % or less of the total solids content, and utilizes a binder with a glass transition temperature of -20° C. or lower.
Further specifications in the claims highlight that the binder in the undercoat layer may consist of latex, with an emphasis on its proportion. Claim 2 indicates that the latex binder can be included in the undercoat layer, while Claim 3 specifies that this latex should make up 25 mass % or more of the total solids content of the undercoat layer. These features aim to enhance the properties of the heat-sensitive recording material, potentially leading to improved recording quality and durability in various applications.
