Abstract: This invention concerns cationic core-shell particles having an acid-insoluble polymeric core component and an acid-swellable polymeric shell component disposed generally about said core so that upon neutralizing said shell with acid, a portion of said shell remains attached or associated with said core; and wherein said shell contains a stabilizer that is covalently bonded to the polymeric shell component. This invention further concerns polymer latex compositions wherein said polymeric shell component has been neutralized and substantially, but not totally, dissolved so as to form a blend of neutralized core-shell polymer and an aqueous solution of neutralized shell polymer. More particularly, the invention concerns the use of latex compositions produced from these cationic core-shell particles to formulate ink jet receptive coatings.

Abstract: Phase change (hot melt) ink compositions for use in a phase change (hot melt) ink jet recording device in which recording is conducted by thermally melting the ink at a temperature above ambient temperature (20° C.) to provide prints that possess high quality images, scratch resistance, abrasion resistance, low-temperature storage stability and flexibility, offset and pick resistance, adhesion, and other desired properties are disclosed to comprise: (a) from about 0.1% to about 30% of one or more colorants; and (b) from about 0.1 to about 99.9% of one or more hybrid polymers. Components other than those listed above may be included in the ink compositions to achieve specific printer, substrate, or end use requirements.

Abstract: This invention concerns a technique and an apparatus that is used for the measurement of bi-axial strain in printed paperboard or paperboard based laminates. Such strain information is useful for determining the margin to failure of various features of laminated paperboard cartons, such as those used in the liquid packaging industry. Knowing such margins of failure is crucial for ensuring integrity of the microbiological barrier in aseptic liquid packaging.

Abstract: A new shaped activated carbon and the method of its manufacture are disclosed. The invention resides in the crosslinking of a polymeric cellulose, such as sodium carboxymethylcellulose (CMC), within the carbon bodies after they are shaped, employing the CMC as a binder for the activated carbon. The approach to attain product mechanical strength and water stability by crosslinking rather than high temperature heat treatment is not obvious from the prior art teaching. The crosslinking reaction occurs at temperatures below 270° C. In addition, this new binder technology produces shaped carbon bodies having key properties beyond the best level that has been accomplished with other binders.

Abstract: The inkjet recording sheet substrate of the present invention comprises a cellulosic sheet support, e.g., paper, having on at least one surface thereof a base coating comprising pigment and binder. The preferred pigment component is a 50/50 mixture of kaolin clay and calcined clay, and the preferred binder component is polyvinyl acetate. This combination of binder and pigment has been found to possess a high absorption capacity for the vehicle of an inkjet ink and good compatibility with ink receptive top coatings applied over the base coat.

Abstract: Vinylic polymer compositions having a weight average molecular weight in the range of about 4,000 to about 12,000 are produced by reacting, in an addition polymerization reaction, a fatty acid rosin mixture and a monomer mixture at a temperature in the range of about 135° C. to about 175° C. These compositions exhibit properties that make them useful as support resins for ink and overprint formulations and as additives for formulating various coating compositions.

Abstract: In a tall oil refining operating plant, a warm water loop is disclosed for cooling the tall oil heads fraction extracted from the crude tall oil, rather than the conventional use of cold water. This avoids condensation and the subsequent solidification of athraquinone pulping aid remaining in the crude tall oil; thus, avoiding fouling of the cooling towers. The temperature of the warm-water is controlled automatically by tempering the cold water entering the warm water “cooling” loop, while removing excessively warm water from said loop to the cooling tower system, as needed.

Abstract: The present invention comprises an alum/rosin composition for internally sizing paper which is useful in any papermaking furnish with moderate to high hardness, as well as methods for preparing such alum/rosin composition. Employing the invention alum/rosin composition of an alum to rosin ratio of 1-3:1, respectively, and of a mean particle diameter of no greater than 10 microns, results in sizing of improved efficiency. In the preparation of the invention sizing composition, the pre-reacting of either neat or solutions of alum and rosin before introducing the mixture into the papermaking furnish, allows the alum to be free to react with the rosin size without any competition from other cations in the furnish.
