Abstract

Optical effect pigment comprising a plurality of layers and a magnetic element, the layers can be arranged in two stacks of asymmetric layers or in a single stack of layers and comprise at least an absorber layer and at least a dielectric layer and can further comprise a reflector layer. The magnetic element presents a magnetisation which is out-of- plane, i.e. predominantly perpendicular to the plane of the pigment, which allows a deposition on the printing substrate whereby the face of the pigment lying up or down on the substrate can be predetermined. Such optical effect pigment has applications in many fields and specifically in security printing, where due to controlled deposition for instance a double- stack pigment will produce a different optical effect on each of its faces.

The method comprises imaging (s100) the marking (50); reading (s200) the code represented by the imaged marking; generating (s300) a signature based on the property of the preexisting layer (40) as detected by the imaging device (10) through at least part of the imaged machine-readable representation of the code; and generating of a measure of authenticity of the object (20) based on the read code and generated signature. The invention also relates to apparatuses, systems and computer programs for that purpose.

Abstract

The present invention relates to formulations for impregnating a porous sintered material and the use as well as methods for impregnating a porous sintered material. More specifically, the present invention relates to formulations for impregnating a porous sintered material, said formulation comprising 40-90 wt.-% of an acrylic monomer, 0.1-10 wt.-% of a radicalic thermal initiator, 0.1-10 wt.-% of a radicalic photoinitiator, 0-30 wt.-% of an organosilane adhesion promoter and 0-5 wt.-% of a siliconic surfactant. Further the invention relates also to a method for impregnating a porous sintered material, comprising the steps of dipping the porous material into a liquid formulation comprising an acrylic monomer; a radicalic thermal initiator; and a radicalic photoinitiator; vacuum treating of the dipped porous material; removing of excess liquid from the surface of the porous material; exposing of the porous material to light radiation; and heat treating of the porous material.

Abstract

The present invention relates to adhesive formulations for bonding materials, comprising 40 to 80 wt.-% of an epoxy monomer, and 15 to 30 wt.-% of an oxetane monomer, and 0.1 to 10 wt.-% of an adhesion promotor, and 0.1 to 5 wt.-% of a sensitizer, and 1 to 10 wt.-% of a radiation and temperature activable photoinitiator or a mixture of a photoinitiator and a thermal initiator. Further, the present invention relates to a method for bonding at least two parts of which one is at least an inert material, comprising the steps applying to one part an adhesive formulation as described, placing another part to be bond on the one part, exposing the parts to UV light radiation and heat treating of the part.

Abstract

The present invention relates to a thermal inkjet print head, comprising a fluid feed channel for delivering fluid, fluid chambers arranged near the fluid feed channel, resistors for actuating the fluid in the chambers, arranged in a staggered pattern with respect to vertical printing lines. At least a part of the fluid feed channel opposite of a rear side of the print head extends substantially orthogonal to the chip surface, and the fluid channel having staggered edges follows the staggered pattern of the resistors so that a fluid path length between a resistor edge and a corresponding staggered edge is substantially similar for each resistor.
