Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
57 words
A base sheet for a heat transfer sheet, comprising: a support member having heat resistance sufficient for heat which is applied to the base sheet during a heat transfer operation, said support member for supporting a thermally transferable layer comprising a first support member, and a second support member being peelably integrated with said first support member.
Claim 2
Dependent Claim
57 words
A base sheet for a heat transfer sheet, comprising: a support member having heat resistance sufficient for heat which is applied to the base sheet during a heat transfer operation, said support member for supporting a thermally transferable layer comprising a first support member, and a second support member being peelably integrated with said first support member.
Claim 3
Dependent Claim
36 words
A base sheet for a heat transfer sheet as claimed in claim 1, further comprising a first releasing layer which is formed on the surface of said second support member not facing said first support member.
Claim 4
Dependent Claim
43 words
A base sheet for a heat transfer sheet as claimed in claim 1, further comprising an adhesive layer which is provided between said first and second support members, wherein said adhesive layer peelably bonds said first support member with said second support member.
Claim 5
Dependent Claim
36 words
A base sheet for a heat transfer sheet as claimed in claim 3, further comprising a first releasing layer which is formed on the surface of said second support member not facing said first support member.
Claim 6
Dependent Claim
35 words
A base sheet for a heat transfer sheet as claimed in claim 4, further comprising a second releasing layer which is formed on the surface of said first support member facing said second support member.
Claim 7
Dependent Claim
23 words
A base sheet for a heat transfer sheet as claimed in claim 1, wherein said first and second support members are couched papers.
Claim 8
Dependent Claim
72 words
A heat transfer sheet, comprising: a base sheet including: a first support member and a second support member peelable integrated with said first support member on a first surface of said second support member, a first releasing layer formed on a second surface of said second support member, and a thermally transferable layer having thermal adhesive properties, said thermally transferable layer peelably provided on said first releasing layer of said base sheet.
Claim 9
Dependent Claim
72 words
A heat transfer sheet, comprising: a base sheet including: a first support member and a second support member peelable integrated with said first support member on a first surface of said second support member, a first releasing layer formed on a second surface of said second support member, and a thermally transferable layer having thermal adhesive properties, said thermally transferable layer peelably provided on said first releasing layer of said base sheet.
Claim 10
Dependent Claim
19 words
A heat transfer sheet as claimed in claim 7, wherein said first and second support members are couched papers.
Claim 11
Dependent Claim
26 words
A heat transfer sheet as claimed in claim 7, wherein said thermally transferable layer comprises a thermally adherable resin and an ink having a coloring agent.
Claim 12
Dependent Claim
37 words
A heat transfer sheet as claimed in claim 9, wherein said thermally adherable resin is selected from the group consisting of polyester resins, acrylic resins, vinyl chloride resins, vinyl chloride copolymer resins, and ethylene-vinyl acetate copolymer resins.
Claim 13
Dependent Claim
26 words
A heat transfer sheet as claimed in claim 7, further comprising an adhesive layer which is formed on the first surface of said second support member.
Claim 14
Dependent Claim
39 words
A heat transfer sheet as claimed in claim 7, further comprising a second releasing layer which is formed on said first support member, said second releasing layer for peeling off said second support member from said first support member.
Claim 15
Dependent Claim
99 words
A heat transfer sheet, comprising: a base sheet including: a first support member and a second support member peelable integrated with said first support member on a first surface of said second support member, a barrier layer member formed on a second surface of said second support member, and a thermally transferable layer formed on said barrier layer, said thermally transferable layer including an ink having a coloring agent which is capable of being thermally sublimated, wherein said barrier layer is a protective layer for preventing the ink from sublimation on the second surface of said second support member.
Claim 16
Dependent Claim
99 words
A heat transfer sheet, comprising: a base sheet including: a first support member and a second support member peelable integrated with said first support member on a first surface of said second support member, a barrier layer member formed on a second surface of said second support member, and a thermally transferable layer formed on said barrier layer, said thermally transferable layer including an ink having a coloring agent which is capable of being thermally sublimated, wherein said barrier layer is a protective layer for preventing the ink from sublimation on the second surface of said second support member.
