  • Recording medium and ink jet recording method
    Patent number: 11945252
    Abstract: A recording medium includes a substrate, a first ink-receiving layer, and a second ink-receiving layer adjacent to the first ink-receiving layer, in this order. The first ink-receiving layer has a positive surface zeta potential, and the second ink-receiving layer has a negative surface zeta potential. The thickness of the second ink-receiving layer is 2 ?m to 15 ?m.

  • METHOD FOR MANUFACTURING RECORDED MATTER HAVING STEREOSCOPIC IMAGE AND MANUFACTURING APPARATUS OF RECORDED MATTER HAVING STEREOSCOPIC IMAGE
    Publication number: 20240001702
    Abstract: A method for manufacturing a recorded matter having a stereoscopic image includes a first heating step, a foaming control liquid application step, and a second heating step. A surface temperature T0 (° C.) of the record medium before being heated in the first heating step, a surface temperature T1 (° C.) of the record medium after being heated in the first heating step, and a foaming start temperature Tf (° C.) of the foaming material satisfy a relationship represented by Formula (1): T0<T<Tf??(1).

  • RECORDING MEDIUM AND METHOD FOR PRODUCING RECORDED MATTER HAVING THREE-DIMENSIONAL IMAGE
    Publication number: 20230294129
    Abstract: A recording medium for producing a recorded matter having a three-dimensional image comprises: a substrate; and a foaming layer being provided on the substrate and containing a foaming material which foams with heat and a binder resin. A contact angle of water to a surface of the foaming layer 30 seconds after the water is brought into contact with the surface of the foaming layer is 30° or more and 80° or less, and a ratio of a diameter of a water droplet 30 seconds after the water is brought into contact with the surface of the foaming layer to a diameter of the water droplet 0.01 seconds after the water is brought into contact with the surface of the foaming layer is 1.3 times or less.
