Abstract

Abstract The dye receiving sheet for preparation of a transparency according to the present invention is a sheet to be used in combination with a heat transfer sheet having a dye layer formed thereon and includes (2) a transparent substrate, (3) a transparent receiving layer provided on the transparent substrate for receiving the dye migrating from the heat transfer sheet corresponding to the energy applied from a thermal head and (5) an optically detectable layer provided on at least a part of the heat transferable sheet. By the provision of the optically detectable layer (5), improvement of running performance, operability within a heat-sensitive device as well as image density and sensitivity during printing can be attained, and also a detection mark can be freely added, whereby operability of the dye receiving sheet can be further improved.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 114 words
A dye receiving sheet for preparation of a transparency, said sheet being used in combination with a heat transfer sheet having a dye layer formed thereon, said dye receiving sheet comprising: a transparent substrate having opposed surfaces; a transparent receiving layer provided on a first opposed surface of said transparent substrate for receiving dye migrating from said heat transfer sheet corresponding to energy applied thereto from a thermal head; an optically detectable support layer formed on an entire second opposed surface of said transparent substrate; and a tackifier layer interposed between said optically detectable support layer and said transparent substrate, such that said optically detectable support layer is freely peelable from said transparent substrate.
Claim 2
Dependent Claim 114 words
A dye receiving sheet for preparation of a transparency, said sheet being used in combination with a heat transfer sheet having a dye layer formed thereon, said dye receiving sheet comprising: a transparent substrate having opposed surfaces; a transparent receiving layer provided on a first opposed surface of said transparent substrate for receiving dye migrating from said heat transfer sheet corresponding to energy applied thereto from a thermal head; an optically detectable support layer formed on an entire second opposed surface of said transparent substrate; and a tackifier layer interposed between said optically detectable support layer and said transparent substrate, such that said optically detectable support layer is freely peelable from said transparent substrate.
Claim 3
Dependent Claim 18 words
The dye receiving sheet of claim 4, wherein said optically detectable support layer comprises a light reflective layer.
Claim 4
Dependent Claim 18 words
The dye receiving sheet of claim 1, wherein said optically detectable support layer comprises a light shielding layer.
Claim 5
Dependent Claim 16 words
The dye receiving sheet of claim 2, wherein said optically detectable support layer comprises a sheet.
Claim 6
Dependent Claim 38 words
The dye receiving sheet of claim 1, wherein either said transparent substrate and said transparent receiving layer, or said optically detectable support layer, are cut to facilitate separation of said optically detectable support layer from said transparent substrate.
Claim 7
Dependent Claim 21 words
The dye receiving sheet of claim 1, wherein a physically detectable mark is further formed on said optically detectable support layer.
Claim 8
Dependent Claim 23 words
The dye receiving sheet of claim 1, wherein a transparent intermediate layer is provided between said transparent substrate and said transparent receiving layer.
Claim 9
Dependent Claim 15 words
The dye receiving sheet of claim 1, wherein an antistatic treatment has been applied thereto.
Claim 10
Dependent Claim 25 words
The dye receiving sheet of claim 1, wherein a lubricating layer is further formed on an outermost surface layer of said optically detectable support layer.
