Abstract: Monoazo dyes of formulas (III) wherein R1, R2, R3, D1 and M are as defined in the specification, are excellent dyes for dyeing and printing of cellulose containing materials and especially for the preparation of inks for ink jet printing.

Abstract: A pigmented aqueous ink jet ink composition is provided which comprises a sarcosinate compound of the formula: R—CO—NMe—CH2—COOM In which R is a ballasting group comprising at least ten carbon atoms and M is hydrogen, an alkali metal cation, an ammonium cation or a substituted ammonium cation. Preferably the ink is prepared by dispersing the pigment in the presence of the sarcosinate compound in water, together with optional co-solvents or other components, and then diluting this dispersion to form the ink.

Abstract: Recyclable and repulpable coated paper stock, preferably for use as ream wrap, comprising a substrate coated on at least one surface with a base coat and at least one additional coat over said base coat. Both coats are water based dispersions of a polymer selected from the group consisting of acrylic polymers, acrylic copolymers, polyvinyl acetate, polyvinyl alcohol, ethylene-vinyl acetate, polyvinyl chloride, styrene butadiene copolymers, polyvinylidiene chloride and its copolymers, or starch. The wax free coating forms a pin-hole free continuous film on the substrate which is resistant to water and water vapor. The invention also includes processes for making and recycling the invented coated paper stocks.

Abstract: There is provided a pigmented aqueous ink set which comprises: (a) a cyan ink which comprises at least one pigment which is a phthalocyanine compound; (b) a magenta ink which comprises at least one pigment which is a quinacridone compound; (c) a yellow ink wherein the pigment is C.I. Pigment Yellow 155; (d) a green ink wherein the pigment is selected from the group consisting of C.I. Pigment Green 7, 36, and mixtures thereof; (e) an orange ink wherein the pigment is selected from the group consisting of C.I. Pigment Orange 34, 36, 43, 61, 64, 71, and mixtures thereof; together with optionally (f) a black ink which comprises a black pigment. Preferably there is also present at least one water soluble organic cosolvent. The pigmented ink set is suitable for use in ink jet printing.

Abstract: A polymer having the following structural formula: where R1=rosin; R2=dimer rosin or fatty acid dimer or R1. The polymer is derived from the reaction of a rosin amidoamine/polyethyleneamine mixture and a multifunctional acrylate ester under controlled conditions.

Abstract: A recording sheet for ink jet printing comprising a support having coated onto said support at least one ink receiving layer and a gelatin containing absorption layer, characterized in that the absorption layer is situated between the support and the ink receiving layer and that it comprises a micelle forming compound selected from salts of branched or unbranched alkyl sulfates of formula CnH2n+1OSO3H, wherein n is from 5 to 25; salts of branched or unbranched alkyl phosphates of formula CnH2n+1OPO3H2, wherein n is from 5 to 25; substituted phenols of general formula (I)  wherein n is from 18 to 50; or salts of substituted phenols of general formula (II)  wherein n is from 5 to 55.

Abstract: A binder formulation comprised of colloidal silica and a polymeric binder, preferably polyvinyl alcohol. A mineral pellet and related low temperature hardening process for making the same. The mineral pellet has sufficient strength to be transported and has sufficient strength for use in iron-making processes.

Abstract: A lunchbox to promote communication between a caretaker and child comprising a container having a food compartment, a voice recording mechanism and a visual component. The voice recording mechanism is housed inside the walls of the container and enables a caretaker and/or child to record a message and permits said message to be retrieved by the child or caretaker.

Abstract: Monoazo dyes of formula (3) wherein A, R1, R2, M and n are as defined in the specification, are excellent dyes for dyeing and printing of cellulose containing materials and especially for the preparation of inks for ink jet printing.
