  • Composition having wet state clarity
    Patent number: 5612397
    Abstract: The composition having wet state clarity includes an aqueous latex binder combination of polymer particles with a diameter of less than 80 nanometers and a thickener. When glitter flakes are dispersed in these novel compositions in their wet state, they glitter more than conventional glitter compositions. Thus, they are more appealing to a consumer or an artist than conventional glitter compositions that tend to be cloudy or dull in their wet state.

  • Polyurethane pressure-sensitive adhesive and laminates therefrom
    Patent number: 4145514
    Abstract: A pressure-sensitive adhesive comprises the reaction product of (A) at least one alkyl acrylate liquid polymer containing both terminal and random hydroxyl functionality, and (B) at least one prepolymer of a polyester glycol or a polyalkylene ether glycol with an excess amount of an aromatic diisocyanate. The adhesive has a full range of desirable adhesive properties, including excellent rolling ball tack, 180.degree. peel adhesion and shear adhesion. The adhesive is useful in both solvent and solvent-free systems.
