A recording medium cartridge in which the quality of external view can be prevented from deteriorating by protecting a writing print layer against damage at the time of ultrasonic welding. The ink layer (20) is obtained by adding a writing filler (21) and resin particles (22) having a mean particle size not smaller than that of the writing filler (21) into ink (23). The resin particles (22) abut against a welding horn (9) to prevent the writing filler (21) from being dropped off or deformed through ultrasonic vibration.

L'invention concerne une cartouche de support d'enregistrement dans laquelle il est possible d'empêcher une détérioration de la qualité de visualisation extérieure en protégeant la couche d'impression d'écriture contre les détériorations au moment du soudage par ultrasons. La couche d'encre (20) est obtenue par l'ajout à l'encre (23) d'une charge d'écriture (21) et de particules de résine (22) présentant une taille particulaire moyenne qui ne soit pas inférieure à celle de la charge d'écriture (21). Les particules de résine (22) viennent buter contre le pistolet de soudage (9) afin d'empêcher la charge d'écriture (21) de tomber ou de se déformer en raison des vibrations des ultrasons.
