  • Patent number: 6177187
    Abstract: The present invention relates to a recording material for the inkjet method with aqueous inks, having at least one temporary substrate material and a porous ink absorption layer which is applied thereon, can be converted into a film and comprises from 60% by weight to 95% by weight of thermoplastic particles having a mean particle size between 1 &mgr;m and 40 &mgr;m, preferably from 5 to 20 &mgr;m, and 5-40% by weight of film-forming binder and, if required, conventional assistants and additives. After conversion of the recording layer into a self-supporting cohesive film by the action of heat and, if required, pressure, said film can be removed from the temporary substrate material at room temperature with a separation force of 10 cN/50 mm strip width to 800 cN/55 mm. In the case of further intermediate layers, the least adhesion of the laminated layers between one another in the laminate is that between temporary substrate material and adjacent layer.
