PURPOSE:To obtain a sharp transfer image, by a method wherein in hot-melt resin, a specific ratio out of acid components is taken as an aliphatic dibasic acid, a specific ratio out of glycol components is taken as an aliphatic glycol, the total of a number of carbons of both of them are taken as a specific quantity and taken as an aliphatic polyester whose molecular weight is specific. CONSTITUTION:In hot-melt resin, at least 80mol% out of acid components is an aliphatic dibasic acid of formula I and at least 70% out of glycol component is an aliphatic glycol of formula II. Then the total of a number of carbons of the aliphatic dibasic acid and the number of carbons of the aliphatic glycol is at least 12 and they are an aliphatic polyester having molecular weight of 4000-15000. (Formula I) HOOC(CH2)nCOOH, (FORMULA II) HO(CH2)mOH, wherein n = even number, m = even number. The ink sheet consists mainly of a coloring material and a substrate and the substrate is a polyester film, a polycarbonate film or a polyamide film. |
