摘要:
An organic solvent-based printing ink composition which comprises a cationic dyestuff of the indole class, an organic solvent, an organic acid which preferably is a resin acid, soluble in the organic solvent, and optionally an organic pigment. The cationic dyestuff is formed (in situ) from its carbinol precursor. The compositions show for example high color strength and excellent rheological properties and can be used in publication or packaging gravure flexographic, lithographic or letterpress printing processes.
摘要:
Pigment compositions comprising an organic pigment and a combination of at least two normally water-soluble coloured compounds (dyes) of opposing charge, i.e. of at least one anionic and one cationic dye are provided. The compositions impart improved rheology on non-aqueous pigment based printing inks and paints.

In certain exemplary embodiments of the present invention, three-dimensional micro-mechanical devices and/or micro-structures can be made using a production casting process. As part of this process, an intermediate mold can be made from or derived from a precision stack lamination and used to fabricate the devices and/or structures. Further, the micro-devices and/or micro-structures can be fabricated on planar or nonplanar surfaces through use of a series of production casting processes and intermediate molds. The use of precision stack lamination can allow the fabrication of high aspect ratio structures. Moreover, via certain molding and/or casting materials, molds having cavities with protruding undercuts also can be fabricated.

摘要:
A process of making a casting includes the steps of designing a mold (1010), fabricating the layers (or laminations) of the mold (1020), stacking and assembling the laminations into a mold (1030), producing a casting (1060) and demolding the casting (1070). If necessary, a derived mold can be made (1040, 1050) prior to producing the casing (1060).
