Title:
SUBLIMATION TRANSFER PRINTING METHOD AND DEVELOPER
Document Type and Number:
WIPO Patent Application WO/2014/073550
Kind Code:
A1
Abstract:
[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 suppressing the staining of non-image areas of a printed product and the unevenness of printing thereof; 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 electrophotographic 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, as essential components, a polyester resin, a sublimable dye, and an external additive which contains strontium titanate as an essential component; and the amount of the strontium titanate is more than 0.3 to less than 3.0 mass% relative to the total mass of the toner. According to the sublimation transfer printing method, a high-quality printed product which exhibits a high color depth and is in an evenly printed state and the non-image areas of which are not stained can be obtained.
