ABSTRACT:
The transfer sheet or web is intended for the use in a heat transfer printing process of cotton, of cotton-polyester blend or of nitrogen containing textile fibers such as wool, silk or nylon.
It comprises on its surface at least one organic impregnating agent which has a melting point between 60.degree. and 230.degree. C. and is no polymer, at least one water insoluble, non-subliming dyestuff, and the minimum amount of a binder. The dyestuff forms a pattern or image which is heat contact printed on said textile substrate without the use of carrier vapors or vacuum. The pattern to be heat transferred may also be prepared in an electrophotographic process using a new toner comprising particles of impregnating agent, binder and dyestuff.
The pattern on the transfer support is transferred at a temperature between 160.degree. and 230.degree. C. during 30 to 60 seconds to said textile substrate. The printings obtained have very good light, rubbing and washing fastnesses; the handling is not impaired.
