Abstract
Imageable products are described which can be made into dry transfer materials and other transfer materials by imaging them in an electrophotographic copier. The imageable products include an adhesive layer having a coating weight of between about 0.5 and 7 grams per square meter, releasably adhered to a substrate. A non-adhesive layer is applied over the adhesive layer, the non-adhesive layer having a thickness of less than about 30 microns and the non-adhesive layer being capable of accepting electrophotographic toner. The non-adhesive layer is incapable of being stripped from the substrate, to which said non-adhesive layer is releasably adhered by said adhesive layer, from a corner of said non-adhesive layer without fracture.
Claims14
Transfer material comprising:
- an imageable product including a substrate, a first adhesive layer releasably adhered to said substrate, and a non-adhesive imageable layer applied over said first adhesive layer, said imageable layer being capable of accepting electrophotographic toner and being of insufficient strength to be stripped from said substrate, to which said imageable layer is releasably adhered by said first adhesive layer, from a corner of said imageable layer without fracture, and an electrophotographic toner image applied to said imageable layer;
- and
- a light-transmitting sheet adherent to said imageable layer bearing said toner image, whereby said substrate and said light-transmitting sheet are separable, with said imageable layer bearing said toner image and said first adhesive layer adhering to said light-transmitting sheet at least where said toner image is applied to said imageable layer.
A dry transfer material comprising an imageable product comprising a substrate having releaseably adhered thereto a first layer of adhesive and over said first layer a non-adhesive imageable layer which is capable of accepting electrophotographic toner, which is of insufficient strength to enable said imageable layer to be stripped from the substrate to which said imageable layer is releaseably adhered by said first adhesive layer from one corner without fracture alone without an overlying application sheet, and having an electrophotographic toner image on said imageable layer, and a light-transmitting application sheet adherent to the toner image bearing imageable layer, whereby on separation of said substrate and application sheet in the image areas, said imageable layer and first adhesive layer material are retained on said application sheet.
In the method of making a transfer material which includes the step of passing an imageable product through an electrophotographic copying apparatus in order to deposit a toner image on said imageable product, the improvement comprising using a transfer material having
- an imageable product including a substrate, a first adhesive layer releaseably adhered to said substrate, and a non-adhesive imageable layer applied over said first adhesive layer, said imageable layer being capable of accepting electrophotographic toner and being of insufficient strength to be stripped from said substrate, to which said imageable layer is releaseably adhered by said first adhesive layer, from a corner of said imageable layer without fracture, and an electrophotographic toner image applied to said imageable layer;
- and
- a light-transmitting sheet adherent to said imageable layer bearing said toner image, whereby said substrate and said light-transmitting sheet are separable, with said imageable layer bearing said toner image and said first adhesive layer adhering to said light-transmitting sheet at least where said toner image is applied to said imageable layer.
