Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
90 words
A thermal transfer recording material comprising a support having thereon a thermal transfer layer containing a dye represented by the following formula (1) ##STR9## wherein R 1 is an alkyl group, a halogen atom or a hydrogen atom; R 2 is an alkyl group or a hydrogen atom; R 3 and R 4 each represent an alkyl or aryl group, provided at least either one of R 3 and R 4 is an aryl group substituted with an alkyl group or an alkyl group substituted with an alkyl-substituted aryl group.
Claim 2
Dependent Claim
90 words
A thermal transfer recording material comprising a support having thereon a thermal transfer layer containing a dye represented by the following formula (1) ##STR9## wherein R 1 is an alkyl group, a halogen atom or a hydrogen atom; R 2 is an alkyl group or a hydrogen atom; R 3 and R 4 each represent an alkyl or aryl group, provided at least either one of R 3 and R 4 is an aryl group substituted with an alkyl group or an alkyl group substituted with an alkyl-substituted aryl group.
Claim 3
Dependent Claim
26 words
The thermal recording material of claim 1, wherein said dye is contained in an amount of 0.05 to 20 g per m 2 of the support.
Claim 4
Dependent Claim
169 words
A thermal transfer recording process comprising superposing an image-receiving material upon a thermal transfer recording material comprising a support having thereon a thermal transfer layer containing a dye represented by the following formula (1) ##STR10## wherein R 1 is an alkyl group, a halogen atom or a hydrogen atom; R 2 is an alkyl group or a hydrogen atom; R 3 and R 4 each represent an alkyl or aryl group, provided at least either one of R 3 and R 4 is an aryl group substituted with an alkyl group or an alkyl group substituted with an alkyl-substituted aryl group; and heating the thermal transfer recording material to effect the reaction of the dye with a metallic ion-containing compound contained in the image-receiving material or in a layer of the thermal transfer recording material which is provided on the thermal transfer layer to thereby form a chelate dye image, wherein said reaction occurs by transfer of the dye from the thermal transfer layer to the metallic ion-containing compound.
Claim 5
Dependent Claim
169 words
A thermal transfer recording process comprising superposing an image-receiving material upon a thermal transfer recording material comprising a support having thereon a thermal transfer layer containing a dye represented by the following formula (1) ##STR10## wherein R 1 is an alkyl group, a halogen atom or a hydrogen atom; R 2 is an alkyl group or a hydrogen atom; R 3 and R 4 each represent an alkyl or aryl group, provided at least either one of R 3 and R 4 is an aryl group substituted with an alkyl group or an alkyl group substituted with an alkyl-substituted aryl group; and heating the thermal transfer recording material to effect the reaction of the dye with a metallic ion-containing compound contained in the image-receiving material or in a layer of the thermal transfer recording material which is provided on the thermal transfer layer to thereby form a chelate dye image, wherein said reaction occurs by transfer of the dye from the thermal transfer layer to the metallic ion-containing compound.
Claim 6
Dependent Claim
29 words
The thermal recording process of claim 3, wherein said metallic ion-containing compound is contained in the image-receiving material or in a heat-meltable layer provided on the thermal transfer layer.
Claim 7
Dependent Claim
29 words
The thermal recording process of claim 3, wherein said metallic ion is selected from Ni +2 , Cu +2 , Cr +2 , Co +2 and Zn +2 .
Claim 8
Dependent Claim
33 words
The thermal recording process of claim 4, wherein said metallic ion-containing compound is contained in an amount of 0.5 to 20 g per m 2 of the image-receiving material or the heat-meltable layer.
Claim 9
Dependent Claim
39 words
The thermal recording process of claim 3, wherein said image-receiving material comprises a support having thereon an image-receiving layer comprising one or more a polymer resins selected from a polyester, polyvinyl chloride, polyvinyl chloride-vinylacetate copolymer, polyvinylbutyral polyvinylpyrrolidone and polycarbonate.
