摘要： Poly(vinylamine salts of mineral acids are produced by reacting acetaldehyde and acetamide at a mole ratio of 1:2-4 with acid catalyst, cracking the ethylidene-bisacetamide which results into vinylacetamide, polymerizing the vinylacetamide with a free radical polymerization catalyst, and hydrolyzing the poly(vinylacetamide) to the desired amine salts by contacting the polyvinylacetamide with an aqueous solution of the corresponding mineral acid. This product may be converted to the free amine, which in turn may function as a precursor in the manufacture of certain polymeric dyes and colorants.

摘要： Water-fast printing of paper stock using a colorant solution containing water-soluble polymeric dyes is accomplished by a three step process. Step 1 is selecting a paper stock characterized as containing at least 250 ppm by weight of cation, particularly a polyvalent metal cation (especially Ca.sup.2+ or Al.sup.3+). In step 2, a colorant solution is applied to the paper. This solution is water-based, containing up to 30 wt % of an organic paper-penetrating agent (such as an alkanol), and at least 500 ppm of one or more anionic group-possessing polymeric colorants. In step 3, the solvent is exhausted by either evaporation (which may be aided by the application of heat) or diffusion into the paper stock, or by a combination of both.

摘要： Several mid UV photo acid generators (PAGs), a chemically amplified photo resist (CAMP), and method for improving nested to isolated line bias are provided. Similarly, photo speed may also be improved. Unlike conventional mid UV PAGs, the present invention's PAG compounds, resist composition, and method do not require a mid UV sensitizer. Specifically, PAGs are provided that bear a chromophore capable of receiving mid UV radiation, particularly I-line, and that are suitable for use in a chemically amplified photo resist having a photo speed of 500 mJ/cm.sup.2 or less, but preferrably 200 mJ/cm.sup.2 or less. For example, the PAGs can be a sulfonium or iodonium salt, such as anthryl, butyl, methyl sulfonium triflate and bis(4-t-butylphenyl)iodonium 9,10-dimethoxyanthracene sulfonate. The chromophore forming a part of the PAGs can be selected from polyaromatic hydrocarbons, for example, chrysenes, pyrenes, fluoranthenes, anthrones, benzophenones, thioxanthones, anthracenes, and phenanthrenes, but preferably anthracenes.

摘要： A group of water-soluble polymeric yellow colors and their preparation is disclosed. These colors comprise a plurality of units of a chromophore of the formula ##STR1## wherein M.sup.+ is a pharmaceutically acceptable monovalent cation attached directly to amine units present in a nonchromophoric polymer backbone. In a preferred embodiment of the invention the backbone is a homopolymer or copolymer of vinylamine. These colorants find special utility as nonabsorbable colorants for edibles, especially foods and beverages, where their yellow hue is an excellent color match for existing monomeric azo food colors such as tartrazine, and as components of acid-insoluble pigment lakes which are themselves suitable for use in edibles.
