  • Publication number: 20030082349
    Abstract: A novel, easy, and efficient manner of toning shades of toluene-based gravure inks is provided, particularly through the incorporation of certain polymeric colorants therein said gravure ink formulations. In addition, such toner additives provide a toning capabilities of carbon black-based gravure inks that provides jetter black appearances with lower degrees of redness and bronzing on various types of printing substrates than other toner formulations of standard alkali blue types of toning additives. Such printed substrates and methods of printing utilizing such novel gravure toner additives are also encompassed within this invention.

  • Publication number: 20030061964
    Abstract: Novel addition products of hydroxyl-protecting groups (such as isocyanates) with oxyalkylene-substituted intermediates, such as poly(oxyalkylenated) aniline compounds, for the eventual production of substituted, and substantially pure, colorants, particularly diazo and triphenylmethane derivatives, through the reaction of such intermediates with certain reactants are provided. These new colorants exhibit improved wax and/or oil solubility and high purity, particularly due to the inability of certain impurities to deleteriously react with the protected hydroxyl groups of either the intermediate or the colorant during and/or after formation thereof. A method for producing such novel colorants through utilization of these novel substantially pure colorant intermediates is also provided.

  • Publication number: 20030050481
    Abstract: Novel addition products of isocyanates with oxyalkylene-substituted aminophenol compounds as intermediates for the production of urethane-substituted xanthene colorants, particularly triphenylmethane derivatives such as rhodarnines, are provided. The xanthene colorants exhibit improved wax and/or oil solubility and high purity. The urethane-substituted xanthene, colorant features very good wax and/or oil solubility, and is believed to be relatively nontoxic. A method for producing this novel colorant is also provided.

  • Patent number: 6069276
    Abstract: This invention relates to very specific oxyalkylene-substituted m-amidoaniline compounds as intermediates for the production of poly(oxyalkylene)-substituted diazo (or other type) colorants. Such an inventive intermediate compound is produced in a single step by reacting an oxyalkylene oxide or alkoxy oxyalkylester having at least three carbon atoms (branched or unbranched), glycidol, or a glycidyl group directly with m-acetoamidoaniline (as a preferred example) at a relatively low temperature. Propylene oxide is the preferred compound. The propylene oxide selectively reacts with the amine group on the base compound without propoxylating the amido group. Such a specific method thus does not require extra time- and cost-consuming steps of protecting the amido nitrogen from attack. After production, this intermediate may be reacted with, for example, a diazotized aromatic amine to ultimately form a diazo colorant.

  • Patent number: 6040482
    Abstract: This invention relates to very specific oxyalkylene-substituted aminophenol compounds as intermediates for the production of poly(oxyalkylene)-substituted xanthene (or other type) colorants. Such an inventive intermediate compound is produced in a single step by reacting an oxyalkylene oxide having from 3 to 12 carbon atoms (branched or unbranched), glycidol, or a glycidyl directly with aminophenol without the use of a catalyst and at a relatively low temperature. Propylene oxide and m-aminophenol are the preferred reactants. The propylene oxide selectively reacts with the amine group on the m-aminophenol without propoxylating the phenolic hydroxyl group. Such a specific method thus does not require extra time- and cost-consuming steps of protecting the phenolic hydroxyl group from attack. After production, this intermediate may be reacted with suitable compounds to ultimately form any number of different colorants, including xanthenes, oxazines, coumarins, and the like.
