Abstract
The invention relates to a photographic element comprising a base and hydrophillic colloid layers comprising at least one layer comprising photosensitive silver halide, wherein said hydrophilic colloid imaging layers further comprise a flexibilizer agent and said flexibilizer agent has a logP of greater than −1.2.
Claims16
A photographic element comprising a base and hydrophillic colloid layers comprising at least one layer comprising photosensitive silver halide, wherein said hydrophilic colloid imaging layers further comprise a flexibilizer agent and said flexibilizer agent has a logP of between −1.2 and 5, and wherein said base has a stiffness of less than 20 millinewtons, said base is provided with a pressure sensitive adhesive on the lower side, wherein said photographic element further is provided with a carrier sheet strippably adhered to said pressure sensitive adhesive, wherein said photographic element is further provided with an environmental protection layer on the upper surface, and wherein said environmental protection layer comprises a greater amount of flexibilizer than said hydrophillic colloid imaging layers.
A method of forming a photographic element comprising providing a photographic element comprising a base and hydrophillic colloid layers comprising at least one layer comprising photosensitive silver halide, bringing said photographic element into contact with an aqueous solution of flexibilizer agent to imbibe said flexibilizer agent into said photographic element, removing said photographic element from said aqueous solution, drying said photographic element to recover a photographic element containing the flexibilizer agent, wherein said flexibilizer agent has a logP of between −1.2 and 5, said base is provided with a pressure sensitive adhesive on the lower side, and a carrier sheet strippably adhered to said adhesive and wherein said colloid layers comprise at least one layer on the upper surface that is free of image forming materials, and wherein said photographic element is further provided with an environmental protection layer on the upper surface, and wherein said environmental protection layer comprises a greater amount of flexibilizer than said hydrophillic colloid imaging layers.
A method of forming a photographic element comprising providing a base material, overcoating said base material with a plurality of hydrophillic colloid layers, wherein said hydrophillic colloid layers comprise at least one layer comprising photosensitive silver halide, and wherein at least one layer comprises flexibilizer agent, and said flexibilizer agent has a logP of greater than −1.2 log P, and wherein said photographic element is further provided with an environmental protection layer on the upper surface, and wherein said environmental protection layer comprises a greater amount of flexibilizer than said hydrophillic colloid imaging layers.
