Abstract
Abstract A temporary carrier of paper, aluminium, regenerated cellulose, polyester terephthalate or polyolefine sheets, or laminates thereof, which carries on one of its surfaces a detachable film of pigmented vinyl resins with a preferably multi-coloured pattern or design, an underlying layer consisting of a mixture of nitrocellulose and an aminoplast or of nitrocellulose and an alkyd resin, wherein there is present on the detachable film a thin adhesive layer containing resins which are soluble in organic solvents and possess a pendulum hardness according to Konig (DIN 53 157) of at least 85 seconds, a process for the manufacture of said temporary carrier, and a process for the dry transfer of all desired design on a definitive A.B.S., polycarbonate, polyvinyl chloride or polystyrene surface, which comprises overlaying said temporary carrier on the surface required to be decorated, on or after the manufacture of the latter, subsequently exposing it to the action of heat, pressure or both, and detaching the temporary support from the decorated surface, optionally after cooling.
