The invention relates to a transfer material for dye sublimation processes, comprising a base paper, which is coated on one side with a color-receiving layer, wherein the base paper contains at least 1.5% by weight, based on the mass of the pulp, of a polymer dispersion selected from the group consisting of polyacrylates, polyesters, polyolefins or mixtures thereof. The invention further relates to a process for producing a transfer material according to the invention, comprising the steps of: (a) producing a base paper on a paper machine, wherein at least 1.5% by weight, based on the mass of the pulp, of a polymer dispersion selected from the group consisting of polyacrylates, polyesters, polyolefins or mixtures thereof are added to the pulp suspension during production of the base paper; (b) drying and smoothing the base paper; (c) applying the color-receiving layer to a surface of the base paper; and (d) drying the transfer material obtained in step (c). The invention further relates to a process for transferring an image onto a receiving material by sublimation, wherein a transfer material according to the invention is printed with an image by way of the inkjet printing process, and the image is transferred onto a receiving material by sublimation.

Transfer material for sublimation printing based on paper as the carrier, with an ink blocking function

The invention relates to a transfer material for the dye sublimation transfer method (sublimation paper) for printing an inkjet print image, comprising a substrate and an ink receiving layer, which layer contains a pigment and a binding agent, on the front face of the transfer material, the ink receiving layer being porous and thermoplastic particles being arranged on the ink receiving layer. The porous ink receiving layer, together with the thermoplastic particles arranged thereon, have an air permeance according to Bendtsen of greater than 100 ml/min and the thermoplastic particles have a diameter of 0.3 &#x3bc;m to 5 &#x3bc;m and a melting point of 60&#xb0; C. to 170&#xb0; C.
