Abstract:
Solvent free, moisture curable reactive hot melt adhesives are prepared using an oxazolidine functional prepolymer and a polyfunctional isocyanate.
Abstract:
Reactive hot melt adhesives compositions with long open time and/or high green strength are prepared by the use of urethane diols. These results are achievable at moderate/low application viscosity or low application temperature.
Abstract:
Compounds and ink compositions. An ink composition comprising a compound of Formula (1) and salts thereof: ##STR1## wherein Ch represents an arrangement of atoms which causes the compound to absorb electromagnetic radiation;R.sup.a and R.sup.b each independently is a spacer group;Y is an interactive functional group;w and x each independently is 0 or an integer equal to or greater than 1; andm and n each independently is an integer equal to or greater than 1, provided that w and x are not both equal to zero and when one of w or x is 0 at least one of m and n is equal to or greater than 2. For use in ink jet printing and electrophotography.
Abstract:
A thermal transfer printing dye sheet comprising a substrate, a dye coat comprising a dye and a polymeric binder on the substrate and an over coat of styrene/butadiene copolymer on the dye coat is disclosed.

Abstract:
The invention relates to a thermally reversible hot melt adhesive that is isocyanate-free, moisture independent, crosslinkable and thermally reversible. The thermally reversible hot melt adhesive may be repeatedly heated and cooled without negatively affecting the performance of the adhesive. The thermally reversible composition may also be used as a primer layer. The thermally reversible hot melt adhesive and primer are particularly well suited for end use applications such as packaging, graphic arts, construction, footwear, textiles, general assembly, automotive and consumer goods.
