<P>PROBLEM TO BE SOLVED: To provide ink which does not cause the exfoliation of colored particles and decolorization due to abrasion and the like after printing. <P>SOLUTION: The ink comprises a predetermined amount of a resin and colored particles dissolved or dispersed in water and/or an organic solvent, and is used as aqueous or oleaginous ink. The colored particles are coated with the resin after printing on account of blending of the resin, and the colored particles are strongly fixed to a print substrate (ink-receiving layer) with the adhesion force of the coating resin. The weight ratio of the resin to the colored particles (the resin/the colored particles) needs to fall in a range of 2.5-25, preferably in a range of 5-20, more preferably in a range of 8-20. <P>COPYRIGHT: (C)2011,JPO&INPIT |
