The present invention relates to image-formation on any selected kind of objective body. The characterizing features reside in such that, based upon fed image data, required images are formed on an image-transferable sheet acting for image carry-over service and in reliance on sublimation image transfer technique, and then, by the use of said sheet with said images thus formed thereon, the formed images thereon are transferringly applied on the objective body. By adopting the above measures, the objective body can be formed sharply and clearly with any desired images, irrespective of kind and configuration thereof, with such superior results of highly improved unity and solidability between the formed images and the objective body to be decorated with.

Image formation on objective bodies

The heat transfer sheet according to this invention including a substrate sheet and a dye carrier layer formed on one side of the substrate sheet and includes a dye and a binder. The dye contained in the dye carrier layer includes a compound having two chromophores linked together through a divalent linking group, and is improved in terms of both color density and storability, thus producing excellent effects.

Heat transfer sheet

A heat transfer sheet for use with a sublimation-type heat transfer printing method, capable of producing a high-quality image having high preservability, comprising a substrate sheet, and a dye layer which is formed on one surface of the substrate sheet, the dye layer containing a sublimable dye represented by the formula (I), (II), (III) or (IV) shown below. ##STR1##

Heat transfer sheets

A heat transfer sheet for use with a sublimation-type heat transfer printing method, capable of producing a high-quality image having high preservability, including a substrate sheet, and a dye layer which is formed on one surface of the substrate sheet, the dye layer containing a sublimable dye represented by the formula (I) shown below. ##STR1##

A heat transfer sheet including (i) a substrate sheet, and (ii) a dye layer which is formed on one surface of the substrate sheet, and includes a binder and a sublimable dye represented by the following formula (I): ##STR1## wherein R.sub.1 and R.sub.2, which may be the same or different and may form together a five- or six-membered ring which may contain an oxygen atom or a nitrogen atom, are a substituted or unsubstituted alkyl, cycloalkyl, aralkyl or aryl group; R.sub.3 is hydrogen, halogen, a cyano group, or a substituted or unsubstituted alkyl, cycloalkyl, alkoxyl, aralkyl, aryl, acyl, acylamino, sulfonylamino, ureido, carbamoyl, sulfamoyl or amino group; R.sub.4 is hydrogen, halogen, a cyano group, or a substituted or unsubstituted alkyl, cycloalkyl, alkoxyl, aralkyl, aryl, acyl, acylamino, sulfonylamino, ureido, carbamoyl, sulfamoyl, amino, heterocyclic or sulfonyl group; R.sub.5 is hydrogen, or a substituted or unsubstituted alkyl, cycloalkyl, alkoxyl, aralkyl, aryl, heterocyclic, acyl, sulfonyl, carbamoyl or sulfamoyl group; X is hydrogen, or an atom or atomic group which forms a five- or six-membered ring together with R.sub.1 ; and m is an integer of 1 or 2.

A heat transfer sheet including a substrate sheet and a dye carrier layer formed on one side of the substrate sheet is characterized in that the dye included in the dye carrier layer is a dye containing chromophores resulting from at least two azo bonds linked together through a non-conjugated linking group.
