  • a metal spatula can be applied to the end face of the ink receiving layer 130, and this position can be set as the removal start position of the ink receiving layer 130. Further, since the ink receiving layer 130 was softened by heating to 110 ° C., only the ink receiving layer 130 could be removed.
  • Example 2 The pellet was prepared by melt-kneading the polyester resin (melting temperature: about 140 ° C.) and cellulose fiber powder in a ratio of 7: 3. From the obtained pellets, an ink permeation preventing layer forming material was produced in the same manner as in Example 1. The ink permeation preventing layer 120 and the ink receiving layer 130 were formed in the same manner as in Example 1, and the ink jet printing was performed. It was possible to remove only the ink receiving layer 130 by heating to 110 ° C. and applying a metal spatula.
  • Example 3 The pellets were prepared by melt-kneading polyester resin (melting temperature: about 140 ° C.), cellulose fiber powder and calcium carbonate in a ratio of 7: 2.2: 0.8. From the obtained pellets, an ink permeation preventing layer forming material was produced in the same manner as in Example 1. The ink permeation preventing layer 120 and the ink receiving layer 130 were formed in the same manner as in Example 1, and the ink jet printing was performed.

In the same manner as in Example 1, the ink permeation preventing layer 120 and the ink receiving layer 130 were formed, and ink jet printing was performed. The heating temperature at the time of removal with a metal spatula was 90.degree. The ink receiving layer 130 and the ink permeation preventing layer 120 were removed, and could be reused without leaving any ink on the substrate 110.

In the same manner as in Example 1, the ink permeation preventing layer 120 and the ink receiving layer 130 were formed, and ink jet printing was performed. It was tried to remove only the ink receiving layer 130 by heating to 90 ° C. and applying a metal spatula. However, the ink permeation preventing layer 120 is also peeled off.
  • Comparative example 2 An ink receiving layer forming material was produced in the same manner as in Example 1 using a polyester resin (melting temperature: approximately 60 ° C.). Using a polyester resin (melting temperature: about 190 ° C.), an ink permeation preventing layer forming material was produced in the same manner as in Example 1.

Abstract

L'invention concerne un support d'enregistrement sur lequel une bonne impression peut être réalisée par un système à jet d'encre, et qui est renouvelable de façon répétée étant donné qu'une encre ne pénètre pas dans la base. Un support d'enregistrement 100 selon la présente invention est obtenu par stratification séquentielle d'une couche de prévention de pénétration d'encre 120 et d'une couche de réception d'encre 130 dans cet ordre sur une base 110. Par chauffage, la couche de réception d'encre 130 peut être retirée de la couche de prévention de pénétration d'encre 120, ou en variante, la couche de prévention de pénétration d'encre 120 sur laquelle la couche de réception d'encre 130 est stratifiée, peut être retirée de la base 110.
