  • Publication number: 20150218399
    Abstract: A colour inkjet ink includes an inorganic colour pigment having a colour selected from the group consisting of cyan, magenta, yellow, blue, green, red, orange, violet, and brown; and at least 1 wt % of an inorganic colourless pigment based on the total weight of the colour inkjet ink, wherein the inorganic colourless pigment has a smaller average particle size than the inorganic colour pigment.

  • Publication number: 20150218398
    Abstract: A radiation curable ink includes a) a monomer including at least one vinyl ether group and at least one (meth)acrylate group; b) a monomer including a five membered cyclic anhydride; and c) an aliphatic tertiary amine. The radiation curable ink allows stable inkjet printing on solder masks exhibiting good adhesion and high scratch resistance after curing.

  • Publication number: 20140349087
    Abstract: An inkjet ink set consisting of a black inkjet ink, a cyan inkjet ink and two inkjet inks A and B, optionally complemented by a white ink and/or a colourless ink, wherein the inkjet ink A has a hue angle H* between 70 and 85 and a chroma C* between 30 and 80; the inkjet ink B has a hue angle H* between 20 and 40 and a chroma C* between 30 and 80; and the CIE L* a* b* coordinates were determined on polyethylene coated white paper for a 2° observer under a D50 light source.

  • Patent number: 5952136
    Abstract: A method is disclosed, and a corresponding thermal imaging medium for use with it, for the formation of an improved heat mode image comprising (A) exposing information-wise to laser radiation a thermal imaging medium comprising (1) a transparent support, (2) an image recording layer containing a hydrophilic binder, a substance capable of converting laser radiation into heat, and a dispersion of a hydrophobic polymer capable of undergoing thermocoagulation by the action of heat and having a built-in UV-absorber. A heat mode image with high density and improved resistance to physical damage is obtained.

  • Patent number: 5882839
    Abstract: A photosensitive element is disclosed, and a process of forming an image with it, comprising, in order, a support with an optional subbing layer (1), a metal image forming layer, a photosensitive layer, and a transparent cover sheet with an optional subbing layer (2).After exposure a delamination step is performed thereby giving rise to a positive and a negative metal image. In a most preferred embodiment the metal layer is a bismuth layer.

  • Patent number: 5814430
    Abstract: A method is disclosed for the formation of a heat mode image with good differentiation between Dmin and Dmax. The method essentially comprises information-wise laser exposure of a layer pack comprising a layer containing a reducing agent, a barrier layer, and a layer containing a reducible organic metal salt, preferably silver behenate. The barrier layer is destructible by laser radiation and allows transfer of reducing agent in the exposed parts while no such transfer occurs in the unexposed parts. Preferably, an overall heat post-treatment is given. A mono-sheet and a two-sheet version of the invention are described.

  • Patent number: 5629130
    Abstract: A new method is disclosed for the formation of a heat mode image comprising exposing to a heat pattern a donor element comprising a reactant (A) while in contact with an acceptor element comprising a reactant (B), the said reactant (A) being transferred by said exposure from said donor element to said acceptor element to form an image therein by reaction of said reactant (A) with said reactant (B), (2) separating said donor and said acceptor element from each other, and (3) optionally giving said acceptor element a post-treatment consisting of a supply of extra energy, characterized in that the said acceptor element comprises spacing particles also containing a said reactant (B), and/or the said donor element comprises spacing particles also containing a said reactant (A), or a said reactant (B), or a density providing compound, preferably carbon black, or combinations thereof.In the preferred embodiment reactant (A) is a reducing agent and reactant (B) is an organic silver salt, preferably silver behenate.

  • Patent number: 5595854
    Abstract: A method is disclosed for the formation of a heat mode image comprising the steps of (i) bringing in close contact a donor element, containing a reducing agent and an radiation to heat converting compound, and an acceptor element, containing a reducible organic silver salt, (ii) exposing this assemblage information-wise by intense infra-red laser radiation, (iii) peeling apart the elements and (iiii) optionally overall heating the separated acceptor element.In a preferred embodiment the laser is an infra-red laser and the radiation to heat converting compound is an infra-red absorbing compound.In an alternative embodiment the radiation to heat converting compound is incorporated in the acceptor.
