Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
103 words
A thermal transfer image receiving material comprising a support having thereon at least one dye imaging receiving layer containing a polyester resin, said polyester resin containing units derived from dicarboxylic acid components and diol components, said units derived from dicarboxylic acid components comprising units containing an anionic SO 3 .sup.θ group in an amount of from 0.1 to 20 mol % of the total units derived from dicarboxylic acid components, and said units derived from diol components comprising units containing a phenylene group, wherein said anionic SO 3 .sup.θ groups and phenylene groups are contained in the linear chain portion of the resin.
Claim 2
Dependent Claim
103 words
A thermal transfer image receiving material comprising a support having thereon at least one dye imaging receiving layer containing a polyester resin, said polyester resin containing units derived from dicarboxylic acid components and diol components, said units derived from dicarboxylic acid components comprising units containing an anionic SO 3 .sup.θ group in an amount of from 0.1 to 20 mol % of the total units derived from dicarboxylic acid components, and said units derived from diol components comprising units containing a phenylene group, wherein said anionic SO 3 .sup.θ groups and phenylene groups are contained in the linear chain portion of the resin.
