ABSTRACT:
The invention relates to a dry transfer process which employs ultraviolet light and photosensitive materials.
The transfer materials used comprise a donor complex layer (c) and a receptor layer (c1). The donor complex layer (c) comprises a carrier (1), a priming layer (2), signs or imprints (3) produced by means of a colorless color-producing material, and a barrier layer (4) which is degradable under the action of ultraviolet light. The receptor layer (c1) comprises a carrier 6 coated with a layer (5) comprising a color developer.
The transferred symbols or images (7) are obtained without the physical passage of an element or of an image from the donor layer to the receptor layer; their quality is comparable to that of printed characters.
