TL;DR: In this paper, the authors proposed a method for transferring a diffusible dye to a dye fixing material by applying water to a fixed material having a mordant and a binder on a support.
Abstract: A novel process for transferring a diffusible dye to a dye fixing material by the steps of (a) applying water to a dye fixing material at least having a mordant and a binder on a support, (b) attaching the dye fixing material to a diffusible dye-containing material, and (c) heating the attached materials to transfer the dye from the dye-containing material to the dye fixing material, wherein the binder contains a cross-linked hydrophilic polymer and a non-cross-linked hydrophilic polymer and the amount of water applied to the dye fixing material is not more than the amount required to maximally swell the layer coated on the dye fixing material. The dye fixing material of the present invention is capable of absorbing a sufficient amount of water in a short period of time, in the process of the present invention, to provide a dye-transferred image of high density in the dye fixing material after heating for a short time, which is substantially free from mottle or color bleeding.
TL;DR: In this paper, a Greek olivine-based silica pigment was produced at laboratory scale by using nitric acid as a solvent and applied to fine base paper and white-top kraftliner board.
Abstract: Silica is commonly used as an
ingredient in the coatings of inkjet papers because of its capability to
provide a coating layer structure combining a high pore volume, into which all
the applied inkjet ink can transfer, and a suitable pore size distribution for
very quick ink absorption. Nowadays, the production of silica pigment is quite
expensive, and therefore, it would be advantageous to find a cheaper raw
material source. In this study, the raw material was Greek olivine from
magnesite mine sidestreams. The silica pigment was produced at laboratory scale
by using nitric acid as a solvent. The target of this work was to clarify how
this produced silica pigment is suited for inkjet coating pigments. The coating
colors were applied by a laboratory rod coater on fine base paper and white-top
kraftliner, and the coated surfaces were printed with a home and office area
inkjet printer. The results showed that the produced olivine-based silica
pigment has a potential in matt inkjet coatings. The coating of the produced
silica pigment increased the print density, decreased the print-through, and
diminished the bleeding of fine paper and white-top kraftliner board. However,
further development work is needed to improve the pigment brightness to a more
acceptable level, and to control the particle size at the nitric acid
dissolution.
TL;DR: In this paper, a registration system for color separation images was proposed, which relates to the dye transfer process of color photography and particularly to the registration system of color separation image registration.
Abstract: This invention relates to the dye transfer process of color photography and particularly to a registration system for color separation images. In the dye transfer process of color photography a color image is transferred from a matrix to a blank or receiving surface. If a relief image is used...
