摘要： A method for forming a printed material includes forming an image on a recording medium; applying particles to a surface of the recording medium, the surface having the image formed thereon; heating the particles applied to the recording medium; and pressurizing, in a thickness direction, a multilayer body obtained by folding the recording medium so that the heated particles are sandwiched between flaps of the recording medium or a multilayer body obtained by placing another medium on top of the recording medium with the heated particles therebetween. The particles contain a styrene resin and a (meth)acrylic acid ester resin. The (meth)acrylic acid ester resin contains two (meth)acrylic acid ester monomer units, and a mass ratio of the (meth)acrylic acid ester monomer units relative to a total of polymerization components is 90 mass % or more.

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.
