  • Publication number: 20130035425
    Abstract: Fluid activatable adhesive compositions and activating fluid(s) for activating the adhesive composition are described herein. The adhesive compositions contain at least two polymers with different hydrophilicities. The hydrophilic polymer has quick tack when exposed to a hydrophilic solvent, such as water or other aqueous solvent, while the hydrophobic polymer provides strong adhesion to a paper or polymeric substrate. The adhesive composition may contain particulate fillers which enable fast exhaustion of the activation fluid out of the adhesive when applied to a substrate, thereby allowing the hydrophobic polymers of the adhesive composition to achieve strong adhesion of the liner-free label to the paper or polymeric substrate. The particulate fillers may also function as anti-blocking agents when liner-free label media are tightly wound in a roll.

    Abstract: A cycloaliphatic diol antimicrobial agent selected from the group consisting of 1,1-cyclohexanedimethanol, 1,2-cyclohexanedimethanol, 1,4-cyclohexanedimethanol, and 2,2,4,4-tetramethyl-1,3-cyclobutanediol was found to provide antimicrobial activity in coating compositions and latexes, and was found to enhance the effectiveness of other antimicrobial agents commonly used in coatings and dispersions. Alone or as part of a preservative system, this cycloaliphatic diol antimicrobial agent in water can provide an easy-to-handle liquid that allows coatings producers to achieve improved microbial control, or achieve equivalent control while using less antimicrobial agents in their formulations. Consequently, the shelf life of the products can be maintained while reducing the use of the traditional preservative, or the shelf-life can be enhanced with addition of this cycloaliphatic diol antimicrobial agent to an existing antimicrobial system.

  • Patent number: 6180707
    Abstract: The process of this invention can be utilized to stabilize tin-coupled rubbery polymers. This process involves adding a chelating diamine or a metal salt of a cyclic alcohol to the rubbery polymer after the tin coupling has been carried out. This invention more specifically discloses a process for improving the stability of a tin-coupled rubbery polymer which comprises adding a metal salt of a cyclic alcohol to the tin-coupled rubbery polymer subsequent to the time at which the tin-coupled rubbery polymer is coupled. The use of metal salts of cyclic alcohols does not lead to recycle stream contamination because they do not co-distill with hexane or form compounds during steam-stripping which co-distill with hexane. In other words, the boiling points of these metal salts of cyclic alcohols are very high, so they do not co-distill with hexane and contaminate recycle streams. Additionally, metal salts of cyclic alcohols are considered to be environmentally safe.

  • Patent number: 5306756
    Abstract: Method for patterning organic polymer layers comprising the sequential steps:A. Applying to a substrate an unpatterned layer of acidic polymer dissolved in a plasticizer,B. Applying to the unpatterned layer a second patterned layer which is a liquid solution of organic base dissolved in a volatile solvent;C. Heating the patterned layer to effect removal of the volatile solvent from the layer and diffusion of the second layer plasticizer and organic base into the underlying areas of the acidic polymer layer; andD. Washing the layers with aqueous solution to effect solubilization of the acidic polymer underlying the patterned areas and removal therefrom of the solubilized polymer and plasticizers.

  • Patent number: 4912160
    Abstract: Stable, non-aqueous solvent solutions of acid-functional polymers are prepared by:(a) reacting, in the presence of an esterification catalyst, a hydroxy-functional acrylic polymer with a cyclic carboxylic anhydride at a reaction temperature from about 35.degree. C. to about 76.degree. C. thereby forming an acid-functional polymer having ester groups and carboxylic acid groups; and(b) maintaining the reaction of the anhydride and hydroxyl groups until the desired amount of acid functionality on the acid-functional polymer has been obtained; and then(c) adding to said acid-functional polymer a stabilizing amount of a low-molecular weight alcohol solvent under conditions which will not cause substantial reaction of the solvent and the acid-functional polymer.
