An imaging element (100) comprising a support and: (1) a radiation-sensitive imaging means which undergoes a change in mobility or optical density in forming a visible image; (2) a material capable of reducing the mobility of a diffusible photographic imaging material; or (3) at least three laterally positioned segmented filters of different spectral absorptions; is characterized in that the support (102) has a planar array of microvessels (108) which individually open toward one of its surfaces (106), next adjacent of said microvessels being laterally spaced by less than the width of adjacent microvessels opening toward either of the surfaces (104 or 106) of the support, and the imaging means, the mobility reducing material and/or the filters being present at least in part in the microvessels. Image spreading due to light scatter during exposure and diffusion of components during processing can be avoided. Elements suitable as lithographic and X-ray films, additive and subtractive color materials, color image transfer and silver salt diffusion transfer materials and methods for their use are described. |
