Abstract: A multi-ply structure which includes a release coating sandwiched between two plies of the structure and present in an amount of about 5 to about 25 g/sq yd., one of the plies of the structure being flexible and in contact with the release coating and removable therefrom by the application of a force of between about 90 to about 600 g/in., as determined by the Keil test procedure, including a composition for forming the release coating and comprising an aqueous coating composition which includes a solids portion and which is effective in forming a coating having release properties, the solids portion of the composition comprising a major amount of resin binder and a minor amount of filler, the filler comprising a major amount of clay and a minor amount of magnesium or calcium hydroxide, and including also a continuous process for forming such multi-ply structure, including particularly a structure comprising a poly(vinyl chloride) ply strippable from a support ply.
