A process for the manufacture of a plastisol film or foam tape laminate comprises providing a continuous liner; forming a release layer along the length of one side of the liner; depositing an adhesive onto the release layer; drying the adhesive; casting a liquid plastisol formulation onto the adhesive; fusing, and in the case of a foam tape, expanding the plastisol formulation to form a thermoplastic layer on the adhesive; and, winding the resulting tape laminate onto rolls. Also, a process for the manufacture of a plastisol film or foam tape laminate comprises providing a continuous liner; forming a release layer along the length of one side of the liner; depositing an adhesive onto the release layer; drying the adhesive; disposing a barrier film onto the dried adhesive; casting a liquid plastisol formulation onto the barrier film; fusing, and in the case of a foam tape, expanding the plastisol formulation to form a thermoplastic layer on the barrier film; and, winding the resulting tape laminate onto rolls.

Process for manufacturing tape products

A one stage process for the manufacture of a plastisol film or foam tape laminate comprises providing a continuous liner; forming a release layer along the length of one side of the liner; depositing an adhesive onto the release layer; casting a liquid plastisol formulation onto the adhesive; fusing, and in the case of a foam tape expanding, the plastisol formulation to form a thermoplastic layer on the adhesive; and, winding the resulting tape laminate onto rolls.

Retroreflective sheeting having an aliphatic polyurethane topcoat is described. The aliphatic polyurethane topcoat is obtainable from a mixture comprising (A) an aliphatic polyurethane derived from an aliphatic polyisocyanate and a polyester polyol prepared from a mixture comprising (A-1) a dicarboxylic acid component comprising isophthalic acid as the major dicarboxylic acid; and (A-2) a polyol component; and (B) cellulose acetate butyrate. The mixture also may contain (C) at least one non-reactive solvent, and optionally, (D) one or more surfactants including, for example, hydroxy-containing non-silicone surfactants.
