Patent ID: 11579540

Abstract:
A method for producing a printed material includes providing pressure-induced phase transition particles on a recording medium having an arithmetic average roughness Ra of 0.07 μm or more and 3.80 μm or less to form a pressure-induced phase transition particle layer having a coverage C within a range of 30% to 90%; bonding the pressure-induced phase transition particles onto the recording medium; and folding the recording medium having the pressure-induced phase transition particles bonded thereon and pressure-bonding the folded recording medium, or pressure-bonding the recording medium having the pressure-induced phase transition particles bonded thereon and another recording medium placed on top of each other. The pressure-induced phase transition particles have at least two glass transition temperatures, and the difference between the lowest glass transition temperature and the highest glass transition temperature among the glass transition temperatures exhibited by the pressure-induced phase transition particles is 30° C. or more.
