PURPOSE:To enhance resolving power by a method wherein the melt viscosity of a color ink layer and the m.p. of a release layer are respectively within specific ranges and the m.p. of an adhesive layer is within a range lower by specific temp. than that of the release layer and coefficients of volume expansion at the time of heat-melting are specific values or more in both of the release layer and the adhesive layer. CONSTITUTION:The melt viscosity of a color ink layer at 100 - 200 deg.C is 10P or more and the m.p. of a heat-meltable release layer is within a range of 70 - 100 deg.C, and the m.p. of a heat-meltable adhesive layer is within a range lower by 10 - 35 deg.C than 70 - 100 deg.C and the coefficients of volume expansion at the time of heat melting of both of the heat-meltable release layer and the heat-meltable adhesive layer are within ranges lower by 10 deg.C than the respective melting points thereof and have values of 15% or more. By this method, an image improved in dot reproducibility and having high resolving power is obtained and the density of a solid part is uniform and a beautiful image can be obtained. |
