A thermosensitive recording element comprising a base having coated thereon a thermosensitive recording layer comprising a dye precursor, the base comprising a composite film laminated to at least one side of a support, the thermosensitive recording layer being on the composite film side of the base, and the composite film comprising a microvoided thermoplastic core layer and at least one substantially void-free thermoplastic surface layer.

Recording element for direct thermosensitive printing

The invention provides acrylamide polymers that, when mixed with water solvent, provide thermoreversible solutions that form low viscosity melts at temperatures separated by a third region of maximum viscosity.

Method of coating thermoreversible heat-thickening polyacrylamides

This invention provides a photographic element containing a polymer layer which reflects a development inhibitor or its precursor released from a DIR compound thereby retarding the diffusion of the development inhibitor to another layer. The polymers used in the barrier layer contain from about 1.times.10.sup.-5 to about 4.times.10.sup.-3 ion forming functional groups. The preferred polymers comprise repeating units of the formula --(A).sub.m -(B).sub.n -- with A derived from a hydrophobic monomer and B derived from an ionic hydrophilic monomer with the more preferred monomers being acrylates, methacrylates, acrylamides and methacrylamides. The invention also provides a method of processing a photographic element containing such a barrier layer.
