Abstract
Abstract Heat sealable labels or the like and methods and marking articles by means of such labels are described. The label includes a flexible support incorporating a heat-curing filmforming resin system in the presence of alkylol or alkoxy alkyl groups and under acid conditions, and an information-bearing marking printed on said support. Such a label when heat sealed to a textile or other article is wash- and wear-resistant and withstands the various treatments to which the article may be subjected.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
125 words
A MARKING ELEMENT PERMANENTLY ATTACHABLE BY HEAT AND PRESSURE TO A SURFACE TO BE MARKE, COMPRISING A PAPER-LIKE FLEXIBLE PERMANENT SUPPORT SHEET COMPLETELY IMPREGNATED WITH A HEAT CURING FILM-FORMING RESIN SYSTEM, A FURTHER COATING OF A HEAT CURING FILM-FORMING RESIN SYSTEM ON ONE SIDE OF SAID SUPPORT AND AN INFORMATION-BEARING MARKING IMPRINTED ON THE OTHER SIDE OF SAID SUPPORT, SAID MARKING ALSO INCLUDING A HEAT CURING, FILM-FORMING RESIN SYSTEM AND SAID FILM-FORMING RESIN SYSTEMS BEING SELECTED FROM THE GROUP CONSISTING OF SOLUBLE POLYAMIDES, SOLUBLE COPOLYAMIDES, AND CROSS-LINKING ACRYLIC RESINS AND INCLUDING ALKYLOL OR ALKOXY ALKYL GROUPS UNDER ACID CONDITIONS FOR CONVERSION OF SAID RESIN SYSTEM UNDER SAID HEAT AND PRESSURE INTO AN INERT, INSOLUBLE AND ABRASION-RESISTIN SUBSTANCE IN SITU ON THE SURFACE TO BE MARKED.
Claim 2
Dependent Claim
125 words
A MARKING ELEMENT PERMANENTLY ATTACHABLE BY HEAT AND PRESSURE TO A SURFACE TO BE MARKE, COMPRISING A PAPER-LIKE FLEXIBLE PERMANENT SUPPORT SHEET COMPLETELY IMPREGNATED WITH A HEAT CURING FILM-FORMING RESIN SYSTEM, A FURTHER COATING OF A HEAT CURING FILM-FORMING RESIN SYSTEM ON ONE SIDE OF SAID SUPPORT AND AN INFORMATION-BEARING MARKING IMPRINTED ON THE OTHER SIDE OF SAID SUPPORT, SAID MARKING ALSO INCLUDING A HEAT CURING, FILM-FORMING RESIN SYSTEM AND SAID FILM-FORMING RESIN SYSTEMS BEING SELECTED FROM THE GROUP CONSISTING OF SOLUBLE POLYAMIDES, SOLUBLE COPOLYAMIDES, AND CROSS-LINKING ACRYLIC RESINS AND INCLUDING ALKYLOL OR ALKOXY ALKYL GROUPS UNDER ACID CONDITIONS FOR CONVERSION OF SAID RESIN SYSTEM UNDER SAID HEAT AND PRESSURE INTO AN INERT, INSOLUBLE AND ABRASION-RESISTIN SUBSTANCE IN SITU ON THE SURFACE TO BE MARKED.
Claim 3
Dependent Claim
24 words
A marking element according to claim 1, wherein the information-bearing marking is produced by means of a printing ink including a cross-linkable resin system.
Claim 4
Dependent Claim
57 words
A marking element according to claim 1, wherein the resin system consists of a soluble polyamide in the presence of alkylol or alkoxy alkyl groups such that at said temperature above the softening temperature cross-linking of the polyamide occurs with the formation of an inert and insoluble compound bonding the label to the surface to be marked.
Claim 5
Dependent Claim
20 words
A marking element according to claim 4, wherein the soluble polyamide consists of a methoxy methyl derivative of a polyamide.
Claim 6
Dependent Claim
26 words
A marking element according to claim 4, wherein the resin system includes a soluble copolyamide in the presence of a cross-linking agent containing alkoxy alkyl groups.
Claim 7
Dependent Claim
19 words
A marking element according to claim 6 wherein the cross-linking agent is a formaldehyde resin containing alkoxy alkyl groups.
Claim 8
Dependent Claim
16 words
A marking element according to claim 1, wherein the resin system includes a cross-linking acrylic resin.
Claim 9
Dependent Claim
133 words
A MARKING ELEMENT PERMANENTLY ATTACHABLE BY HEAT AND PRESSURE TO A SURFACE TO BE MARKED, COMPRISING A PAPER-LIKE FLEXIBLE PERMANENT SUPPORT SHEET COMPLETELY IMPREGNATED WITH A HEAR CURING FILM-FORMING RESIN SYSTEM, A FURTHER COATING OF A HEAT CURING FILM-FORMING RESIN SYSTEM ON ONE SIDE OF SAID SUPPORT AND AN INFORMATION-BEARING MARKING IMPRINTED ON THE OTHER SIDE OF SAID SUPPORT, SAID INFORMATION-BEARING MARKING BEING PROTECTED BY A TRANSPARENT PROTECTIVE LAYER CONSISTING OF A FILMFORMING RESIN SYSTEM, EACH OF SAID FILM-FORMING RESIN SYSTEMS BEING SELECTED FROM THE GROUP CONSISTING OF SOLUBLE POLYAMIDES, SOLUBLE COPOLYAMIDES, AND CROSS-LINKING ACRYLIC RESINS, AND ALSO INCLUDING ALKYLOL OR ALKOXY ALKYL GROUPS UNDER ACID CNDITIONS FOR CONVERTION OF SAID RESIN SYSTEM UNDER SAID HEAT AND PRESSURE INTO AN INERT, INSOLUBLE AND ADRASION-RESISTING SUBSTANCE IN SITU ON THE SURFACE TO BE MARKED.
Claim 10
Dependent Claim
133 words
A MARKING ELEMENT PERMANENTLY ATTACHABLE BY HEAT AND PRESSURE TO A SURFACE TO BE MARKED, COMPRISING A PAPER-LIKE FLEXIBLE PERMANENT SUPPORT SHEET COMPLETELY IMPREGNATED WITH A HEAR CURING FILM-FORMING RESIN SYSTEM, A FURTHER COATING OF A HEAT CURING FILM-FORMING RESIN SYSTEM ON ONE SIDE OF SAID SUPPORT AND AN INFORMATION-BEARING MARKING IMPRINTED ON THE OTHER SIDE OF SAID SUPPORT, SAID INFORMATION-BEARING MARKING BEING PROTECTED BY A TRANSPARENT PROTECTIVE LAYER CONSISTING OF A FILMFORMING RESIN SYSTEM, EACH OF SAID FILM-FORMING RESIN SYSTEMS BEING SELECTED FROM THE GROUP CONSISTING OF SOLUBLE POLYAMIDES, SOLUBLE COPOLYAMIDES, AND CROSS-LINKING ACRYLIC RESINS, AND ALSO INCLUDING ALKYLOL OR ALKOXY ALKYL GROUPS UNDER ACID CNDITIONS FOR CONVERTION OF SAID RESIN SYSTEM UNDER SAID HEAT AND PRESSURE INTO AN INERT, INSOLUBLE AND ADRASION-RESISTING SUBSTANCE IN SITU ON THE SURFACE TO BE MARKED.
Claim 11
Dependent Claim
74 words
A marking element according to claim 1, wherein said information-bearing marking is protected by a transparent protective layer consisting of a film-forming resin system selected from the group consisting of soluble polyamides, soluble copolyamides, and cross-linking acrylic resins and including alkylol or alkoxy alkyl groups under acid conditions for conversion of said resin system under said heat and pressure into an inert, insoluble and abrasion-resisting substance in situ on the surface to be marked.
