Sublimation transfer printing method and method for inhibiting non-image areas from being stained

摘要

[Problem] To provide: a sublimation transfer printing method of a dry developing system, particularly a dry nonmagnetic developing system, still particularly a dry nonmagnetic one -component developing system, said sublimation transfer printing method being capable of achieving a high color depth and inhibiting the staining of non-image areas of a printed product; a printed product obtained by the printing method; an intermediate recording medium which is to be used in the printing method; and a toner. [Solution] A sublimation transfer printing method which comprises adhering a toner to an intermediate recording medium according to an electro- photographic process, and transferring the dye contained in the toner adhered to the intermediate recording medium to an object to be printed through the sublimation of the dye, wherein: the toner comprises a styrene-acryl resin, a sublimable dye and an external additive as essential components; and the external additive contains strontium titanate as an essential component. According to the sublimation transfer printing method, a high-quality printed product which has a high color depth and the non-image areas of which are not stained can be provided.
