Abstract
A fusion thermal transfer recording sheet having a base layer (A) of a uniaxially stretched film containing 40 to 85 wt % of a thermoplastic resin and 60 to 15 wt % of an inorganic or organic fine powder; and a surface layer (B) of a uniaxially stretched film, provided on at least one surface of the base layer (A), containing 30 to 90 wt % of a thermoplastic resin and 70 to 10 wt % of an inorganic fine powder which has an average grain size equals to or smaller than that of the inorganic or organic fine powder contained in the base layer (A) and has a grain surface modified by hydrophilic treatment is disclosed. The fusion thermal transfer recording sheet is excellent in applicability to color fusion thermal transfer recording, applicability to thermal transfer bar code recording under a hot and humid atmosphere, and in ink adhesiveness.
