  • Patent number: 4387153
    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.

  • Patent number: 4367252
    Abstract: This invention relates to arrangements for the dry transfer of printed characters. Such arrangements hitherto have comprised a carrier sheet of which one face is provided with printed characters which are transferable to a receiving surface by pressure exerted on the carrier sheet. The characters are protected by a sheet of siliconized paper. However, such an arrangement is not always easy to handle because the siliconized sheet can become creased or crumpled, damaging the characters.According to the invention, the entire area of at least one of the faces of said carrier sheet is covered with a guard sheet which is attached to said carrier sheet along at least a part of its periphery, and which is provided with preformed cuts to define a frame fastened to said carrier sheet and a central portion which is intended to be removed when the arrangement is put to use.
