Methods for producing an information carrier produced by: (1) providing an information carrier precursor comprising a 5 rigid sheet or support; a receiving layer configuration having an image-receiving side and a non-image-receiving side, the receiving layer configuration comprising at least one pigment and at least one binder, (2) pattern-wise or integrally at least partially transparentizing the receiving layer configuration with a vaporizable liquid thereby providing a transparent pattern on the at least partially transparentized receiving layer; (3) using a light source to write a pattern or modify the pattern in the layer or element capable of a machine-readable change upon absorption of UV, visible or IR 25 radiation after transmission through at least part of the transparentized areas of the receiving layer configuration; evaporating the vaporizable liquid, thereby producing an information carrier.

摘要:
The present invention relates to a method for making direct-positive photographic images by developing light-sensitive materials in the presence of development nucleators which do not cause loss of sensitivity during exposure or unevenness of development. More specifically the invention relates to the formation of direct-positive images having a high maximum density and high exposure latitude and to photographic materials for use in said formation, which is accomplished by a method for making direct-positive images comprising:image-wise exposing a photographic light-sensitive silver halide material comprising a support and a layer of an internal latent image-type silver halide emulsion, the pAg of which has been adjusted to a pAg-value between 9.0 and 10.5 inclusive before coating, anddeveloping said exposed photographic silver halide material in a surface developer in the presence of a development nucleator with a group promoting adsorption to silver halide.It has been found that in a particular embodiment of this invention a development-nucleating amount of a hydrazine compound with a 7-hydroxy-s-triazolo-[1,5-a]-pyrimidine group as group promoting adsorption to silver halide is very useful.
