Abstract: A method for producing a printed material includes forming a color image having an image area ratio of 20% or less on a peripheral edge portion of a recording medium by using a coloring material; providing pressure-induced phase transition particles to a region of the recording medium, the region including the peripheral edge portion; bonding the color image and the pressure-induced phase transition particles onto the recording medium; and folding the recording medium having the color image and the pressure-induced phase transition particles bonded thereon and pressure-bonding the folded recording medium, or pressure-bonding the recording medium having the color image and the pressure-induced phase transition particles bonded thereon and another recording medium placed on top of each other. The pressure-induced phase transition particles contain a styrene resin and a (meth)acrylic acid ester resin, the styrene resin contains styrene and a vinyl monomer other than styrene as polymerization components, the (meth)acrylic acid ester resin contains at least two (meth)acrylic acid esters as polymerization components, and a mass ratio of the (meth)acrylic acid esters is 90 mass % or more of a total of all polymerization components of the (meth)acrylic acid ester resin. The pressure-induced phase transition particles have at least two glass transition temperatures, and a difference between the lowest glass transition temperature and the highest glass transition temperature among the glass transition temperatures of the pressure-induced phase transition particles is 30° C. or more.
