摘要:
The flow and handling characteristics of arylide yellow and orange pigment dispersions are improved by incorporating in them a small amount of a rheology modifier that is the product obtained by reacting an arylide yellow or orange pigment with a primary diamine and a glycidyl ether.

Compositions, methods, apparatuses, kits, and combinations are described for permanently or temporarily re-designing, decorating, and/or re-coloring a surface. The compositions useful in the present disclosure include a décor product that is formulated to be applied and affixed to a surface. If desired, the décor product may be substantially removed from the surface before being affixed thereto. If a user desires to remove the décor product, the décor product is formulated to be removed by a number of methods including, for example, vacuuming, wet extraction, chemical application, and the like. If the user desires to affix the décor product to the surface in a permanent or semi-permanent manner, the décor product may be affixed to the surface by applying energy thereto in the form of, for example, by a sealant composition such as, for example, a solvent. The décor product may also be utilized in the form of a kit or in conjunction with a design device, such as a stencil, to control the application of the décor product to create, for example, a pattern on the surface.

This invention provides a device that enhances a computer user's visual environment by providing a useful and/or aesthetically pleasing frame for the computer display screen. In a preferred embodiment, the screen is removably attached to the bezel of a computer display in a manner that permits substantially the entire display screen to be viewed through an opening in the screen frame.
摘要:
A process for improving the color value of a pigment and for imparting stability to a water-based printing ink containing such pigment which comprises adding a polyester or polyether to the strike tank during the pigment conditioning step; the preferred polyether is methyl hydroxypropyl cellulose and the preferred polyester is benzoic acid-modified trimellitic anhydride polyester.

Poly (alkylene oxide) substituted acetoacetanilides of the formula: ##STR1## wherein B comprises a divalent bridging moiety selected from the group consisting of C.sub.1 -C.sub.6 alkylene, --NHSO.sub.2 --, --O--, --CO--, --COO--, and --NCHO--; X comprises a poly (alkylene oxide) having a number average molecular weight of about 200 to 10,000; R comprises 0 to 4 moieties independently selected from the group consisting of C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy and halogen; and d is an integer of 1 to 3. The poly (alkylene oxide) substituted acetoacetanilides are prepared by reacting a poly (alkylene oxide) monoamine, diamine or triamine with isatoic anhydride followed by acetoacetylation of the resultant aminobenzamide. The substituted acetoacetanilides are useful for preparing improved diarylide pigment compositions which in turn are useful for preparing storage stable printing inks (especially of the publication gravure type).

Water-based diarylide pigment compositions containing diarylide pigment modified with water-soluble amines. The pigment compositions are useful in both water-based coating and ink compositions.
摘要:
The present invention provides a reversible piezochromic system that changes appearance upon application of a mechanical force. The reversible piezochromic system includes a cavity defined by a first substrate and a second substrate. The cavity includes at least a first fluid. The first fluid spreads when a mechanical force is applied to the system. The relaxation time of the first fluid depends upon the internal forces of the system. These internal forces at least include the surface energy differences between the substrates and the fluid or fluids, and the rheological properties of the fluid or fluids.
摘要:
Colored conductive fluids for electrowetting or electrofluidic devices, and the devices themselves, are disclosed. The colored conductive fluid includes a polar solvent and a colorant selected from a pigment and/or a dye. The polar solvent has (a) a dynamic viscosity of 0.1 cP to 1000 cP at 25° C., (b) a surface tension of 25 dynes/cm to 90 dynes/cm at 25° C., and (c) an electrowetting relative response of 20% to 80%. The colored conductive fluid itself can have an electrical conductivity from 0.1 μS/cm to 3,000 μS/cm and can have no greater than 500 total ppm of monatomic ions with ionic radii smaller than 2.0 Å and polyatomic ions with ionic radii smaller than 1.45 Å. The colored conductive fluid should not cause electrical breakdown of a dielectric in the device in which it is employed. An agent for controlling electrical conductivity can optionally be added to the colored conductive fluid.
