  • Patent number: 5340389
    Abstract: The invention provides aqueous multicolor compositions containing discrete hydrated colored globules dispersed in an aqueous dispersing medium containing a film forming material. To impart the enhanced properties of long term stability and resistance to application by means of brush and roller, the globules are obtained by reacting two or more pigment containing hydrophilic colloids selected from carboxylated cellulose colloids, polysaccaride gums and acrylic polymers with at least two metal cations selected from Fe.sup.3+, Al.sup.3+, Ca.sup.2+, and Mg.sup.2+. The thus obtained colored globules contain from 2.5 to 20.0% by weight of pigment and fillers and 10 to 40% by weight of a film forming resin. The globules constitute and are about 60 to 90% by weight of the final composition, while the dispersing medium is 40 to 10% by weight of the final composition.

  • Patent number: 5321064
    Abstract: A biodegradable interpolymer and composition is prepared by the reactive blending of a synthetic polymer having functional groups with a naturally occurring biodegradable polymer such as a carbohydrate or protein compound. During reactive blending, the synthetic polymer can undergo a chemical reaction with the biodegradable natural polymer which results in covalent and physical bonding between the two polymers, thereby forming an interpolymer. By this process, a biodegradable interpolymer composition is produced that is suitable for molding various articles.

  • Patent number: 4524164
    Abstract: A thermosetting adhesive resin suitable for binding lignocellulosic materials to form products, such as plywood or particle board, is prepared by heating an aqueous sugar or starch solution in the presence of an inorganic acid or its ammonium salt and a metal ion catalyst to obtain a partially polymerized resin which is reacted with an organic acid anhydride just prior to application to the lignocellulosis materials. The adhesive formula contains no formaldehyde and the preferred aqueous solutions are whey or whey byproduct concentrates.

  • Patent number: 4394470
    Abstract: A polyethylene terephthalate moulding composition is disclosed having uniformly dispersed therein 10-25,000 ppm of caramel as a colorant. The colorant is non-toxic, does not affect the transparency of the polyester, and does not cause aldehyde formation. The caramel may have been formed in situ from a mono- or disaccharide which has been added to the bis(beta-hydroxyethyl)terephthalate before or during polycondensation or to the molten polyester. The color may have been intensified by adding an alkaline reacting compound. The composition may moreover contain further colorants. The composition is particularly suitable for use in the manufacture of food containers such as boxes, trays and bottles.
