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 requried 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.

Claim 1
Independent Claim
180 words
A PROCESS FOR THE TRANSFER OF A VINYL RESIN FILM ONTO A DEFINITIVE A.B.S., POLYCARBONATE, POLYVINYL CHLORIDE OR POLYSTYRENE SURFACE WHICH COMPRISES BRINGING THE SAID A.B.S., POLYCARBONATE, POLYVINYL CHLORIDE OR POLYSTYRENE SURFACE INTO CONTACT WITH THE ADHESIVE SURFACE OF A TEMPORARY CARRIER COMPRISING, AS THE BASE, PAPER, ALUMINUM, REGENERATED CELLULOSE, POLYESTER TEREPHTHALATE, OR POLYOLEFINE SHEETS OR LAMINATES THEREOF SAID BASE CARRYING ON ONE OF ITS SURFACES A DETACHABLE FILM OF PIGMENTED VINYL RESINS, HAVING AN UNDERLYING LAYER BETWEEN THE BASE AND SAID DETACHABLE FILM CONSISTING OF A MIXTURE OF NITROCELLULOSE AND AN AMINOPLAST OR OF NITROCELLULOSE AND AN ALKYD RESIN, THE SAID DETACHABLE FILM HAVING AN OVERLYING THIN ADHESIVE LAYER CONTAINING RESINS WHICH ARE SOLUBLE IN ORGANIC SOLVENTS AND WHICH POSSESS A PENDULUM HARDNESS ACCORDING TO KONIG (DIN 53157) OF AT LEAST 85 SECONDS, EXPOSING THE SURFACES WHILE IN CONTACT TO THE ACTION OF HEAT, PRESSURE OR BOTH TO CAUSE THE ADHESIVE LAYER AND DETACHABLE FILM TO TRANSFER ONTO THE SAID A.B.S., POLYCARBONATE, POLYVINYL CHLORIDE OR POLYSTYRENE SURFACE, AND REMOVING THE SAID TEMPORARY CARRIER BASE WITH THE SAID UNDERLYING LAYER.

Claim 4
Dependent Claim
110 words
A process according to claim 1 wherein the temporary carrier comprises a paper sheet as base the said base carrying on one of its surfaces the following superimposed layers: a. a layer of a mixture consisting of 40 to 60% nitrocellulose, the remainder being a condensation product of urea and formaldehyde or alkyd resin, b. a transparent or opaque print layer based on finely disposed organic pigment embedded in polyvinyl chloride or a vinyl chloride and vinyl acetate copolymer, and c. a thin adhesive layer containing polyalkylmethacrylate resins which are soluble in organic solvents and which have a pendulum hardness according to Konig (DIN 53157) of at least 85 seconds.
Claim 5
Dependent Claim
33 words
A process according to claim 1 wherein a foamed polystyrene surface is brought into contact with the temporary carrier surface and the temperature to which the surfaces are exposed is maintained below 130*C.
