Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
118 words
Thermal transfer image reception paper comprising: an image reception paper base material constituted by a core material and two sheets of synthetic paper provided on both sides of said core material, respectively; a dyeable resin layer provided on at least one surface of said image reception paper base material directly or through an intermediate layer; each sheet of said synthetic paper having a composite structure including two layers; one of the layers of said synthetic paper composite structure located on said resin layer side being a paper-like layer having fine pores, and only one layer of the composite structure of said synthetic paper located on each side of said core material being a paper-like layer having fine pores.
Claim 2
Dependent Claim
118 words
