  • Patent number: 10968357
    Abstract: A transfer-printing ink contains a pigment and a fixing resin. The mass ratio of the pigment to the fixing resin is 1:1 to 1:5, and the ink has a viscosity of 3 mPas to 10 mPas at 23° C. The ink is ejected onto a transfer paper base by an ink-jet recording device when transfer paper is prepared. The ink is then transferred from the transfer paper to cloth as a result of the transfer paper, with the cloth laid over it, being heated.

  • Publication number: 20180361768
    Abstract: A transfer-printing method includes a transfer paper preparing step, a transferring step, and a releasing step. The transfer paper preparing step involves forming an image using transfer-printing ink containing a pigment and a fixing resin by ejecting the ink onto a transfer paper base and then drying at a temperature lower than the cross-linking temperature of the fixing resin to obtain transfer paper. The transferring step involves transferring the image formed on the transfer paper to cloth by pressing, while heating at a temperature higher than the cross-linking temperature of the fixing resin. The releasing step involves releasing the transfer paper from the cloth having the image fixed to it. The layer thickness of the ink layer formed on the transfer paper base is 50 nm to 500 nm, and, in the transferring step, the ink layer is transferred in the form of film to the surface of the cloth.
