Abstract: A composition is disclosed which is useful in preventing dental plaque and tartar from forming on the teeth. The composition includes compounds which are esters or their mono or double salts derived from lysine in combination with straight chain or branched, saturated or unsaturated, monovalent aliphatic alcohols having 4 to 20 carbon atoms.

Abstract: A novel cured pressure-sensitive adhesive-coated sheet material comprising a flexible backing having bonded thereto a pressure-sensitive adhesive material containing copolymers of 2-ethyl hexyl acrylate, butyl acrylate and glycidyl acrylate or glycidyl methacrylate. The monomer-mixture for the pressure-sensitive adhesive material may also contain minor amounts of monomers with acid anhydride groups or monomers with carboxyl groups. The curing of the pressure-sensitive adhesive material is accomplished by heating the copolymers to a temperature between 60.degree. and 100.degree. C., in the presence of a zinc chloride catalyst whereby the copolymers become cross-linked to obtain a solvent-, heat- and weather-resistant pressure-sensitive adhesive-coated sheet material.

Abstract: An adhesive resin comprising the polymer of dimethyl-di-(cyclohexen-3)-yl-methane as well as a copolymer of this compound with at least one mono-or di- ethylenically unsaturated hydrocarbon or chlorinated hydrocarbon, said hydrocarbon having 4 to 12 carbon atoms. A method of making these resins and a method of causing adhesion using such resins are also disclosed, as well as compositions including this resin.
