Latest Patents

Ishiyama holds a patent for an "Ink jet recording sheet and method for producing the same." The primary objective of this invention is to provide ink jet recording sheets that exhibit a high color forming property while ensuring smooth operation in printers. The design includes at least one ink receiving layer and a gloss developing layer, which are coated using a cast coating method. These layers are laminated on one side of a support, while a back-coat layer containing a pigment and a binder is applied on the opposite side. A key feature of this invention is the adjustment of the static friction coefficient between the gloss developing layer and the back-coat layer to 0.9 or lower under specific conditions. Additionally, the use of alumina hydrate as a pigment in the gloss developing layer contributes to the overall effectiveness of the product.
