A matrix transfer medium with the binder being an aliphatic polyester polyurethane. This is formed directly on an untensilized polyethylene terephthalate film substrate. Porous magnesium silicate in minor amounts as a filler beneficially controls ink flow at printing. Overall good performance as to both ribbon feed and printing is realized.

Aliphatic polyurethane matrix transfer medium and porous magnesium

Low tack pressure sensitive compositions containing polyethylene, a tackifier, an isobutylene polymer, a copolymer of ethylene and/or propylene and a monoethylenically unsaturated ester and a carboxylic acid and/or ester thereof and use thereof to remove erroneously typed images from a substrate.

Adhesive correction composition and method of use

Low tack pressure sensitive compositions containing a paraffinic wax and/or polyethylene resin, a tackifier, an isobutylene polymer, and a copolymer of ethylene and/or propylene and a monoethylenically unsaturated ester; and use thereof to remove erroneously typed images from a substrate.
