Abstract
A method for producing a well-integrated multilayer material having a first material layer adjacent a second material layer, the second material layer being sparingly compatible with the first material layer includes binding the first material layer to the second material layer with an adhesive layer consisting essentially of 60 to 95 parts of a high viscosity binder component and 5 to 40 parts of a low viscosity binder component. The low viscosity binder component is capable of binding to the first material layer and the second material layer and the high viscosity binder component is capable of interacting with the low viscosity binder component.
