摘要:
A process is provided for preparing an acrylic copolymer latex having improved mechanical and shear stability comprising emulsion polymerizing at least one ethylenically unsaturated monomer having up to 23 carbons in the presence of, by weight based on the total monomer content, a) from about 0.05% to about 5.0% of a protective colloid with a molecular weight of less than 75,000, and b) from about 0.01% to about 1.5% of at least one water soluble free radical polymerization initiator. This latex provides coating manufacturers the flexibility of either eliminating surfactants altogether from coating or to use small amounts thereof.
摘要:
A modified vegetable protein adhesive binder and a process for producing the same is disclosed wherein an alkaline protein dispersion is treated with organosilane reagent in an amount sufficient to modify the protein material. The modified vegetable protein adhesive binder provides greater pigment structuring when employed in paper coating compositions containing pigment and other materials such as latex. The modified binder also results in coatings with an improved degree of wet rub resistance.

A modified vegetable protein adhesive binder and a process for producing the same is disclosed wherein an alkaline protein dispersion is formed of a vegetable protein material and said dispersion is treated with an alkyl acrylamidoglycolate alkyl ether in an amount sufficient to modify the protein material. The modified vegetable protein adhesive binder provides greater binder strength when employed in paper coating compositions containing pigment and other materials such as latex. The modified binder also results in coatings with good ink receptivity.
摘要:
A coated base paper for use in an ink jet recording process exhibits excellent ink solution spreading and wipe resistance. The coating comprises a pigment and/or filler of non-flake structure, and a binding agent dried on the paper. The pigment content is at least about 90% by weight of the dried coating and has a particle mean diameter of about 0.05-4.0 .mu.m. The binding agent is predominantly hydrophilic.
摘要:
It has been discovered that the combination of certain polyvalent metal ions with certain proteinaceous foaming agents will significantly enhance the efficacy of proteinaceous foaming compositions. The present invention affords the means for achieving significantly improved protein foam from vegetable protein hydrolyzates which normally fail to possess the foaming efficacy of conventional proteinaceous foam agents such as egg albumen and caseinates. The improved foamed products may be obtained by employing a combination of polyvalent ions such as calcium and zinc with enzymatically hydrolyzed soy protein whipping agents which are characterized as being soluble throughout the pH 4 to 7 range. The proteinaceous foaming composition may be utilized for a variety of industrial and food applications. The present foaming compositions are particularly useful in providing coated paper products.
