PURPOSE:To obtain a support having excellent smoothness, capable of recording clear images thereon from low to high densities without irregularities in density and showing little thermal curling, by blending a pulp with a specified viscosity in a raw paper. CONSTITUTION:A pulp having a low viscosity of 5-12cP, as measured according to Tappi T 230 om-82, is blended in pulps used for making a raw paper, in a receiving sheet for thermal transfer which comprises a thermoplastic resin coat layer on at least one side of the raw paper and a heat-dyeable receiving layer on the resin coat layer. If the viscosity is less than 5cP, fiber strength is low, and the strength of the raw paper is low. If the viscosity exceeds 12cP, the smoothness of the raw paper is lowered, resulting in a lower uniformity of dots. The use of the low-viscosity pulp enhances markedly the texture of the paper, leading to less lowering in strength, notwithstanding the mixing of the low-strength pulp. When an excessively large amount of the low-viscosity pulp is used, however, a reduction in strength will occur. If the amount of the low-viscosity pulp is excessively large, the effect of the pulp is not displayed. Thus, the low-viscosity pulp is used in an amount of 10-70wt.% based on the total amount of the pulps. |
