Abstract
A thermoplastic resin film (i) which has a degree of dimensional change through heating and cooling (a) in the range of from −2% to 2% as measured by thermomechanical analysis in the range of from room temperature to 135° C., or which has a degree of thermal shrinkage of 1.8% or lower upon heating at 130° C. for 30 minutes or longer; and a label paper employing the same. The label paper has suitability for heated-roll fixing type electrophotographic printers and is satisfactory in curling after printing.
