Stress-absorbing thermal imaging laminar medium

Abstract From the Canadian patent

There is disclosed a laminar thermal imaging medium comprising a pair of sheet members and at least a layer of imageforming substance confined therebetween in laminar relation thereto, said laminar thermal imaging medium being actuatable in response to intense image-forming radiation for production of an image in said image-forming substance, said medium material having a tendency toward stress-induced adhesive failure at the interface therein having the weakest adhesivity and such, tendency being reduced by a polymeric stress-absorbing layer in close proximity to said interface, said polymeric stressabsorbing layer being capable of absorbing physical stresses applied to said laminar …
