Abstract

Abstract The disclosure concerns a method of transferring printed indicia from a paper sheet to a backing surface member by first pressing a film of tacky, contact adhesive, held on a release sheet, against the paper sheet. The sandwich consisting of the paper, the indicia, the adhesive and the release sheet is then soaked in water to remove the paper, leaving the indicia on the surface of the film, but eliminating to a substantial extent, the tacky character of the surface. Next, the backing surface is prepared to receive the indicia-carrying film, by either wetting the same with a solvent such as lacquer thinner which will render the adhesive film tacky or applying a layer of tacky, contact adhesive to this backing surface. It was determined that heat and pressure may also be operative to effect the transfer to the backing surface.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 26 words
In the process defined in claim 1, wherein said carrier layer is a rubber base contact cement and wherein the release sheet is a silicone-coated sheet.
Claim 2
Dependent Claim 19 words
In the process defined in claim 1, wherein the carrier layer, release sheet unit is a transfer adhesive sheeting.
Claim 3
Dependent Claim 54 words
In the process defined in claim 1, wherein said backing member is formed of an absorbent material and the aforesaid surfaces are rendered adherable by moistening said backing member with a solvent adapted to soften and tackify said indicia retaining carrier layer when the latter is placed against the surface of said backing member.
Claim 4
Dependent Claim 34 words
In the process defined in claim 2, wherein said backing member is formed of an absorbent material and the aforesaid surfaces are rendered adherable by moistening said backing member with an organic, volatile solvent.
Claim 5
Dependent Claim 17 words
In the process defined in claim 4, wherein said backing member is formed of a fibrous material.
Claim 6
Dependent Claim 15 words
In the process defined in claim 6, wherein said backing member is formed of cloth.
Claim 7
Dependent Claim 37 words
In the process defined in claim 1, wherein the aforesaid surfaces are rendered adherable by applying thereto a layer of tacky contact adhesive of a type which is compatible with the contact adhesive of said carrier layer.
Claim 8
Dependent Claim 44 words
In the process defined in claim 8, including the further step of applying a fixative to the surface of the carrier layer after said release sheet has been removed, said fixative being characterized by the property of rendering the exposed carrier layer surface nontacky.
Claim 9
Dependent Claim 14 words
In the process defined in claim 9, wherein said fixative is a clear lacquer.
Claim 10
Dependent Claim 45 words
In the process defined in claim 1, wherein said backing surface is rendered adherable to said indicia-retaining carrier layer by the application of heat to increase the temperature of the backing surface and carrier layer to a point where the carrier layer is rendered tacky.
Claim 11
Dependent Claim 24 words
In the process defined in claim 1, wherein said contact adhesive is composed of a film-forming polymer or combination of polymers which possess tack.
Claim 12
Dependent Claim 26 words
In the process defined in claim 1, wherein said contact adhesive comprises a pressure sensitive adhesive composed of a film forming polymer and a tackifier resin.
Claim 13
Dependent Claim 17 words
In the process defined in claim 1, wherein the carrier layer is a rubber base contact cement.
Claim 14
Dependent Claim 18 words
In the process defined in claim 1, wherein the aforesaid surfaces are rendered adherable by heating the same.
Claim 15
Independent Claim 110 words
A method of producing a transfer sheet comprising a release sheet, a normally tacky contact adhesive film carried upon the release sheet and printed indicia carried upon the film at the surface thereof including the steps of: a. applying the adhesive film to the relEase sheet; b. placing the release sheet against a paper sheet having said indicia printed thereon to adhere to the surface of the paper sheet to produce a sandwich of layers; c. soaking the sandwich of layers in a water solution until the paper has softened; and d. removing the paper, whereby the adhesive retains the indicia but is rendered substantially nontacky at the exposed surface.
