  • Patent number: 10046556
    Abstract: An image recording method includes a reaction liquid applying step; a first liquid composition applying step; an ink applying step of applying an ink containing a second water-soluble resin so as to at least partly overlap with an area where the first liquid composition is applied on an intermediate transfer member to form an intermediate image; and a step of transferring the intermediate image to a recording medium by bringing the intermediate image into contact with the recording medium to separate the intermediate image from the intermediate transfer member. The temperatures Tc, T1 of the intermediate image and intermediate transfer member from start of the contact to the separation are adjusted to be not less than the glass transition temperature Tgs of the second water-soluble resin. The temperatures Tr, T2 of the intermediate image and recording medium at the separation are adjusted to be less than Tgs.

  • Patent number: 10040942
    Abstract: A process for the production of a quinacridone pigment composition is provided. For use in environmentally friendly inks, the pigment composition offers high chroma, high color strength, and high dispersion stability. Also provided is a water- or alcohol-based environmentally friendly ink that contains a quinacridone pigment composition obtained through this process. According to the inventors' research, adding a quinacridone derivative to a quinacridone solid solution in two different steps in a process, during and after treatment for the control of crystals, gives the resulting pigment composition the color characteristics of high color strength and high chroma, as well as high dispersion stability. The present invention is based on these findings.
