Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
104 words
A heat mode thermal transfer recording material comprising a) a support; b) a light-heat converting layer comprising 1) a water-soluble near infrared-absorptive dye having a sulfo group; and 2) a water soluble binder; c) an ink layer containing a colorant and a binder which can be softened or melted upon heating, and transferred; and d) a cushioning layer; wherein said water-soluble near infrared-absorptive dye has an absorption peak at wavelengths longer than 700 nm and the water solubility of said dye is not less than 0.1% by weight of water, and said light-heat converting layer is disposed between said support and said ink layer.
Claim 2
Dependent Claim
104 words
A heat mode thermal transfer recording material comprising a) a support; b) a light-heat converting layer comprising 1) a water-soluble near infrared-absorptive dye having a sulfo group; and 2) a water soluble binder; c) an ink layer containing a colorant and a binder which can be softened or melted upon heating, and transferred; and d) a cushioning layer; wherein said water-soluble near infrared-absorptive dye has an absorption peak at wavelengths longer than 700 nm and the water solubility of said dye is not less than 0.1% by weight of water, and said light-heat converting layer is disposed between said support and said ink layer.
