Abstract
Abstract A sheet for receiving a thermally formed design of material from a transfer sheet or the like of thermally transferable heatsensitive material. The surface of the receiving sheet is defined by material which has been formed under conditions yielding a reticulated, stippled or particulated texture thereby providing a plurality of spaced contacts for receiving the transferred material with a resolution of at least 5.0 line pairs per millimeter.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
91 words
In combination, a donor sheet carrying a thermally transferable heat-sensitive material, a donee sheet, for receiving said heat sensitive material, having a surface textured with a continuous plurality of ridges defining discrete depressed regions, opposed portions of said ridges being spaced a distance of 5-45 microns whereby to provide spaced contacts receptive to said heat-sensitive material for receiving, upon contact with said layer, thermal transfer from said layer and separation of said sheets, a thermally formed design of said material having a resolution of at least 5.0 line pairs per millimeter.
Claim 2
Dependent Claim
91 words
In combination, a donor sheet carrying a thermally transferable heat-sensitive material, a donee sheet, for receiving said heat sensitive material, having a surface textured with a continuous plurality of ridges defining discrete depressed regions, opposed portions of said ridges being spaced a distance of 5-45 microns whereby to provide spaced contacts receptive to said heat-sensitive material for receiving, upon contact with said layer, thermal transfer from said layer and separation of said sheets, a thermally formed design of said material having a resolution of at least 5.0 line pairs per millimeter.
Claim 3
Dependent Claim
15 words
The invention according to claim 1 in which the surface of said sheet is reticulated.
Claim 4
Dependent Claim
23 words
The invention according to claim 2 in which said surface-defining material includes a substantial amount by weight dispersed therein of inorganic particulate material.
Claim 5
Dependent Claim
20 words
The invention according to claim 2 in which said surface-defining material comprises polyvinyl chloride as the major organic component thereof.
Claim 6
Dependent Claim
29 words
The invention according to claim 2 including from about 0.5 to about 8 parts by weight of kaolin per part of said surface-defining material dispersed in said surface-defining material.
Claim 7
Dependent Claim
23 words
The invention according to claim 1 in which the surface of said sheet is defined by organic polymeric material having a reticulated texture.
Claim 8
Dependent Claim
92 words
In combination, a donor sheet carrying a layer of thermally transferable heat-sensitive material, a donee sheet for receiving said heat-sensitive material, said sheet comprising a base, particulate material and a binder securing said particulate material to said base, said particulate material extending above said binder to define a textured surface in contact with said heat-sensitive material for receiving, upon contact with said layer, thermal transfer from said layer and separatiOn of said sheets, a thermally formed design of said heat-sensitive material having a resolution of at least 5.0 line pairs per millimeter.
Claim 9
Dependent Claim
92 words
In combination, a donor sheet carrying a layer of thermally transferable heat-sensitive material, a donee sheet for receiving said heat-sensitive material, said sheet comprising a base, particulate material and a binder securing said particulate material to said base, said particulate material extending above said binder to define a textured surface in contact with said heat-sensitive material for receiving, upon contact with said layer, thermal transfer from said layer and separatiOn of said sheets, a thermally formed design of said heat-sensitive material having a resolution of at least 5.0 line pairs per millimeter.
