Abstract

Abstract A dry transfer article comprising an adhesive layer, a graphic pattern contained thereon, an actinic radiation-transmissive, ink-receptive layer between the adhesive layer and the graphic layer, and an application tape over the graphic pattern. The adhesive layer comprises an actinic radiation-responsive composition. Exposure of the article to actinic radiation selectively differentiates the adhesive potential between those portions of the adhesive layer underlying the graphic pattern and the exposed portions of the adhesive layer. After application of the article to a substrate, removal of the application tape causes selective removal of unwanted areas leaving desired graphic pattern on the substrate, i.e., the transfer article if self-weeding.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 36 words
A dry transfer article comprising an adhesive layer, a graphic layer comprising a predetermined graphic pattern, an actinic radiation-transmissive, ink-receptive layer between said adhesive layer and said graphic layer, wherein said adhesive layer is actinic radiation-responsive.
Claim 2
Dependent Claim 36 words
A dry transfer article comprising an adhesive layer, a graphic layer comprising a predetermined graphic pattern, an actinic radiation-transmissive, ink-receptive layer between said adhesive layer and said graphic layer, wherein said adhesive layer is actinic radiation-responsive.
Claim 3
Dependent Claim 11 words
The article of claim 1 wherein said adhesive layer is pressure-sensitive.
Claim 4
Dependent Claim 21 words
The article of claim 1 further comprising an overlayer on said graphic layer and the exposed portions of said ink-receptive layer.
Claim 5
Dependent Claim 15 words
The article of claim 3 wherein said overlayer comprises an actinic radiation-responsive, actinic radiation-transmissive layer.
Claim 6
Dependent Claim 22 words
The article of claim 4 wherein said overlayer passes through said ink-receptive layer and penetrates said adhesive layer responsive to actinic radiation.
Claim 7
Dependent Claim 13 words
The article of claim 3 further comprising an application tape on said overlayer.
Claim 8
Dependent Claim 27 words
The article of claim 1 wherein said ink-receptive layer comprises a layer of discrete, inert particles being sufficiently proximate to one another to present an ink-printable surface.
Claim 9
Dependent Claim 15 words
The article of claim 1 wherein said ink-receptive layer comprises a non-particulate organic resin layer.
Claim 10
Dependent Claim 22 words
The article of claim 1 further comprising an application tape on said graphic layer and the exposed portions of said ink-receptive layer.
