Abstract
Abstract An upper thermo-sensitive paper is coated with an adhesive agent on a part of the rear surface thereof, and a lower thermo-sensitive paper is coated with a release agent on the upper surface thereof at the area corresponding to the adhesive agent coated area of said upper thermo-sensitive paper. The upper thermo-sensitive paper is laid on and adhered to the lower thermo-sensitive paper. By separating the upper thermo-sensitive paper from the lower thermo-sensitive paper at the boundary plane between the adhesive agent layer and the release agent layer, the upper thermo-sensitive paper can be used as a tack paper and the lower thermo-sensitive paper can be used as a copying paper.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
120 words
A copying tack paper for a thermal printer, comprising: an upper thermo-sensitive paper coated with an adhesive agent on a part of the rear surface thereof, and having a first printing region free of said adhesive agent; and a lower thermo-sensitive paper coated with a release agent on the upper surface thereof at an area corresponding to the adhesive agent coated part of said upper thermo-sensitive paper, and having a second printing region free of said release agent and corresponding to said first printing region; said upper thermo-sensitive paper being adhered to said lower thermo-sensitive paper by contact of said adhesive agent with said release agent, wherein both of said first and second printing regions can be simultaneously heat developed.
Claim 2
Dependent Claim
120 words
A copying tack paper for a thermal printer, comprising: an upper thermo-sensitive paper coated with an adhesive agent on a part of the rear surface thereof, and having a first printing region free of said adhesive agent; and a lower thermo-sensitive paper coated with a release agent on the upper surface thereof at an area corresponding to the adhesive agent coated part of said upper thermo-sensitive paper, and having a second printing region free of said release agent and corresponding to said first printing region; said upper thermo-sensitive paper being adhered to said lower thermo-sensitive paper by contact of said adhesive agent with said release agent, wherein both of said first and second printing regions can be simultaneously heat developed.
Claim 3
Dependent Claim
138 words
A copying tack paper for a thermal printer, comprising: an upper thermo-sensitive paper coated with a transfer ink on the rear surface thereof, a part of said transfer ink being coated with an adhesive agent, said upper thermo-sensitive paper having a first printing region free of said adhesive agent; and a lower copying paper coated with a release agent on the upper surface thereof at an area corresponding to the adhesive agent coated part of said upper thermo-sensitive paper, said lower copying paper having a second printing region corresponding to said first printing region and being free of said release agent; said upper thermo-sensitive paper being laid on and adhered to said lower copying paper; wherein said first printing region is developed by heat which melts said transfer ink causing it to adhere to said lower copying paper.
Claim 4
Dependent Claim
138 words
A copying tack paper for a thermal printer, comprising: an upper thermo-sensitive paper coated with a transfer ink on the rear surface thereof, a part of said transfer ink being coated with an adhesive agent, said upper thermo-sensitive paper having a first printing region free of said adhesive agent; and a lower copying paper coated with a release agent on the upper surface thereof at an area corresponding to the adhesive agent coated part of said upper thermo-sensitive paper, said lower copying paper having a second printing region corresponding to said first printing region and being free of said release agent; said upper thermo-sensitive paper being laid on and adhered to said lower copying paper; wherein said first printing region is developed by heat which melts said transfer ink causing it to adhere to said lower copying paper.
Claim 5
Dependent Claim

Claim 6
Dependent Claim
109 words
A copying tack paper for a thermal printer, comprising: an upper thermo-sensitive paper coated with an adhesive agent on a part of the rear surface thereof, and an intermediate thermo-sensitive paper coated with a release agent on the upper surface thereof at an area corresponding to the adhesive agent coated part of said upper thermo-sensitive paper and coated with an adhesive agent on the rear surface thereof, and a ground paper coated with a release agent on the upper surface thereof, said upper thermo-sensitive paper being laid on and adhered to said intermediate thermo-sensitive paper, and said intermediate thermo-sensitive paper being laid on and adhered to said ground paper.
Claim 7
Dependent Claim
114 words
A copying tack paper for a thermal printer, comprising: an upper thermo-sensitive paper coated with a transfer ink on the rear surface thereof, a part of said transfer ink being coated with an adhesive agent, and a copying paper coated with a release agent on the upper surface thereof on area corresponding to the adhesive agent coated part of said upper thermo-sensitive paper and coated with an adhesive agent on the rear surface thereof, and a ground paper coated with a release agent on the upper surface thereof, said upper thermo-sensitive paper being laid on and adhered to said copying paper, and said copying paper being laid on and adhered to said ground paper.
Claim 8
Dependent Claim
114 words
A copying tack paper for a thermal printer, comprising: an upper thermo-sensitive paper coated with a transfer ink on the rear surface thereof, a part of said transfer ink being coated with an adhesive agent, and a copying paper coated with a release agent on the upper surface thereof on area corresponding to the adhesive agent coated part of said upper thermo-sensitive paper and coated with an adhesive agent on the rear surface thereof, and a ground paper coated with a release agent on the upper surface thereof, said upper thermo-sensitive paper being laid on and adhered to said copying paper, and said copying paper being laid on and adhered to said ground paper.
