Abstract
Abstract A heat transfer is described for labelling clear plastics which uses as the transfer layer a coating comprising at least 30 percent by weight of an oxidized, esterified, partially saponified montan wax. An ink image is printed over the wax and, after transfer by application of heat and pressure, is smoothed, clarified and glossed by exposure to a jet of hot gas or other heating means to remelt the transferred wax, followed by solidification in the clear state.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
19 words
A heat transfer according to claim 1 where said oxidized wax comprises a predominant amount of said transfer coating.
Claim 2
Dependent Claim
22 words
A heat transfer according to claim 1 where said oxidized wax comprises at least 30 percent by weight of said transfer coating.
Claim 3
Dependent Claim
27 words
A heat transfer according to claim 3 wherein said oxidized wax is substantially clear when melted in a liquid layer less than about 1/4 inch in thickness.
Claim 4
Dependent Claim
17 words
A heat transfer according to claim 3 where said transfer layer includes at least one synthetic resin.
Claim 5
Dependent Claim
18 words
A heat transfer according to claim 3 further comprising a transferable ink design printed over said transfer coating.
Claim 6
Dependent Claim
93 words
The method of labelling the surface of a receiving body which comprises (a) providing a heat transfer according to claim 6, (b) transferring said design to said surface by contacting the surface with said design while applying heat and pressure thereto to melt the wax layer, and thereafter smoothing and clarifying the image by (c) remelting the wax adherent to said surface by means of a high-temperature jet of gas for a time sufficient to melt said wax without substantial heating of said body, and (d) solidifying the wax in a clear state.
Claim 7
Dependent Claim
21 words
The method according to claim 7 wherein said high-temperature jet of gas is a flame which impinges on said transferred wax.
Claim 8
Dependent Claim
22 words
The method according to claim 7 wherein said jet of gas is air at a temperature of at least about 300* F.
Claim 9
Dependent Claim
14 words
The method according to claim 7 wherein said receiving body is a clear plastic.
