A release sheet for transferring a graphic onto an associated object, comprising: i)- a carrier film, the carrier film being formed by a flexible polymeric material having melting point greater than about 150°C; ii)- a release layer disposed on the carrier film, the release layer having been applied to the film in a release layer solvent solution that is non-degradating to the carrier film; iii)- a transfer layer disposed on the release layer, the transfer layer having been applied to the release layer in a solution that is non-degradating to the release layer; and iv)- a graphic disposed on the transfer layer, the graphic being selected in such a manner it is non-degradating to the transfer layer, wherein the release sheet containing the graphic is configured to be able to be applied to an associated object designed to be then cured or vulcanized at an elevated temperature, and wherein the graphic is configured to transfer to the object during curing or vulcanization and wherein the carrier film and release layer are configured to be removable from the object following curing or vulcanization; characterized in that, in combination: a)- the carrier film is a non-fluorinated film; b)- the release layer is a wax release layer having a drop point between about 80°C and 120°C and an acidic value of about 20 mg KOH/gram; and c)- the transfer layer is a thermoplastic or elastomer having a good adhesion to the rubber; d)- the graphic is made of an ink or colorant including a rubber and pigment composition, wherein said rubber and pigment composition forming the graphic is soluble in a non-polar solvent. i)- a carrier film, the carrier film being formed by a flexible polymeric material having melting point greater than about 150°C; ii)- a release layer disposed on the carrier film, the release layer having been applied to the film in a release layer solvent solution that is non-degradating to the carrier film; iii)- a transfer layer disposed on the release layer, the transfer layer having been applied to the release layer in a solution that is non-degradating to the release layer; and iv)- a graphic disposed on the transfer layer, the graphic being selected in such a manner it is non-degradating to the transfer layer, wherein the release sheet containing the graphic is configured to be able to be applied to an associated object designed to be then cured or vulcanized at an elevated temperature, and wherein the graphic is configured to transfer to the object during curing or vulcanization and wherein the carrier film and release layer are configured to be removable from the object following curing or vulcanization; characterized in that, in combination: a)- the carrier film is a non-fluorinated film; b)- the release layer is a wax release layer having a drop point between about 80°C and 120°C and an acidic value of about 20 mg KOH/gram; and c)- the transfer layer is a thermoplastic or elastomer having a good adhesion to the rubber; d)- the graphic is made of an ink or colorant including a rubber and pigment composition, wherein said rubber and pigment composition forming the graphic is soluble in a non-polar solvent. a)- the carrier film is a non-fluorinated film; b)- the release layer is a wax release layer having a drop point between about 80°C and 120°C and an acidic value of about 20 mg KOH/gram; and c)- the transfer layer is a thermoplastic or elastomer having a good adhesion to the rubber; d)- the graphic is made of an ink or colorant including a rubber and pigment composition, wherein said rubber and pigment composition forming the graphic is soluble in a non-polar solvent.
