Abstract
Official abstract text for this publication.
Articles including a polymer film, a plasticizer and a substrate are included. A method of bonding the film to the substrate includes the use of the plasticizer which provides a durable bond by using a lower temperatures and shorter bonding times than would be required in the absence of the plasticizer.
First claim
Opening claim text (preview).
What is claimed is: 1. An article comprising: a heat-activated adhesive multilayer film comprising at least an inner layer, a center layer and an outer layer, wherein the center layer comprises a polymer comprising polyurethaneurea with a weight average molecular weight of from about 40,000 to about 250,000, the outer layer comprises polymer comprising a polyurethaneurea with a molecular weight of about 70,000 and the inner layer comprises polymer comprising a polyurethaneurea with a molecular weight of about 120,000; and a substrate to which the heat-activated adhesive multilayer film is bonded by application of heat and pressure in the presence of a plasticizer comprising water placed on the heat-activated adhesive multilayer film prior to or during bonding to a substrate. 2. The article of claim 1 , wherein said substrate comprises a fabric. 3. The article of claim 2 , wherein said fabric substrate is selected from the group consisting of nylon, cotton, polyester, wool, silk, and combinations thereof.
