Polyester resin for a dye receptive-layer used in thermal transfer recording.

摘要

A polyester resin for a dye receptive layer of a recording medium for sublimation type heat-sensitive transfer recording process, and a recording medium using thereof, which has superior resistance to light exposure and dark fade out. A polyester resin for a dye receptive layer of a recording medium for sublimation type heat-sensitive transfer recording process, wherein said polyester resin is formed by using a diol component containing a diol compound shown in Formula (1) in a range of 5-80 molar % with respect to the total diol component, and a receiving medium using thereof. <CHEM> (In Formula (1), each of R1 and R2 represents an alkylene group having a number of carbon atoms within a range of 1-12.)
