Abstract
A method for manufacturing a removable information sheet includes: forming a toner image on a recording medium; applying an energy-ray-curable pressure-sensitive composition precursor onto the medium to form an energy-ray-curable pressure-sensitive composition precursor layer; irradiating, with an energy ray, the medium to cure the layer and form an energy-ray-curable pressure-sensitive composition; and attaching faces with the composition and pressure-bonding the faces. A region size of a toner-image flat part is 200 μm or less in the image, which is determined by a measurement method including: defining a site at a depth of 2 μm or more from a surface of a solid part of the image as a recess; defining a site other than the recess as the flat part; acquiring and binarizing a micrograph of the solid part; drawing circles out of contact with the recess; and defining a largest circle diameter as the size of the flat part.
