Patent ID: 8080305

Claim:
A decalcomania product, transferable by a transfer solvent and printable by a solvent based ink plotter, comprising: a support on which two or more layers are applied: a layer directly contacting the support, or release layer, comprising: a polyvinyl alcohol having an average molecular weight ranging from 31000 to 124000 uma, a maximum hydrolysis rate of 90 percent, that is soluble in the transfer solvent and at a first percentage ranging from 5 to 20 percent by weight of the release layer; an organic raw material which is adhesive if soaked, soluble in said transfer solvent, and at a second percentage ranging from 25 to 80 percent by weight of the release layer, wherein the first percentage and second percentage are selected in such a way that the sum of the first percentage and the second percentage is less than or equal to 100; and a farthest layer from said support, or printable layer, having a solid content that is less soluble in said transfer solvent than the release layer, said printable layer comprising: a polyvinyl alcohol having an average molecular weight ranging from 31000 to 124000 uma, a maximum hydrolysis rate of 90 percent, that is soluble in the transfer solvent and at a third percentage ranging from 1 to 20 percent by weight of the printable layer; a polymer or copolymer that is printable by a solvent based ink plotter, has affinity with the solvent contained in the ink and is at a fourth percentage ranging from 25 to 80 percent by weight of the printable layer, said polymer or copolymer that is printable is selected from the group consisting of ethylene vinyl acetate, ethylene vinyl chloride, polyvinyl acetate, copolymers of ethylene with vinyl acetate, copolymers of ethylene with vinyl chloride, copolymers of ethylene with styrene, and chlorinated or fluorinated vinyl copolymers; and an organic raw material which can become an adhesive if soaked, is soluble in said transfer solvent and is at a fifth percentage ranging from 1 to 40 percent by weight of the printable layer, wherein the third percentage, the fourth percentage and the fifth percentage are selected such that the sum of the third percentage, the fourth percentage and the fifth percentage is less than or equal to 100 and at least 15% of the printable layer is soluble in said transfer solvent.
