Abstract: Disclosed is a radiation crosslinkable water-dispersible adhesive composition that is useful in forming paper and plastic articles and other products that can be recycled through a process which includes washing or repulping in aqueous media. The cross-linkable water-dispersible adhesive composition is preferably used as a hot melt adhesive. The cross-linkable water-dispersible adhesive composition is a low molecular weight, branched copolyester containing a sulfomonomer and unsaturated moieties. The radiation crosslinked adhesive composition has more cohesive strength and viscosity than its corresponding uncross-linked adhesive, yet is still water-dispersible during product recycling.

Abstract: The heat sealing film and a magnetic transfer strip contain an adhesive layer comprising thermoplastic, immiscible binder components. One component is spherical, amorphous and embedded in finely distributed form in a homogeneous layer of the other, highly crystalline components in such a way that the spherical component protrudes hemispherically from the layer. The spherical binder is a glassy solid up to at least 60.degree. C. and above 80.degree. C. is plastically deformable. The hemispheres protruding from the adhesive layer produce a uniform, fine roughness of the surface. Both heat sealing film and magnetic transfer strip are nonblocking up to at least 60.degree. C. and heat-sealable at temperatures greater than 80.degree. C. The adhesive layer imparts to a magnetic recording medium a uniform thickness of the adhesive joint and a permanent, temperature-resistant adhesive force.

Abstract: A press for transferring images from pictures or substrates to other objects, such as mugs or other cylindrical objects. The press comprises a flexible band or jacket type clamp lined with suitable compressible material and capable of being clamped tightly against a generally cylindrical outer surface of an object, with the image to be transferred against such outer surface. The image is urged into intimate contact with the outer cylindrical surface by the clamping pressure transferred through the compressible material. An adjustable clamp permits ease of placement of the band type press onto the object to which the image is to be transferred.
