Abstract
Photographic elements, multicolor filters and receivers are disclosed having supports providing microvessels for materials such as radiation-sensitive materials, imaging materials, mordants, silver precipitating agents and materials which are useful in conjunction with these materials. Processes of forming microvessels and introducing materials therein are also disclosed. Processes of forming images are disclosed employing microvessel containing elements. Image transfer processes are disclosed for producing one or a combination of silver and multicolor subtractive primary images alone or in combination with multicolor additive primary images.
Claims19
In an element comprising a support means having first and second major surfaces and, on said support means, at least three laterally offset filters,
- the improvement comprising:
- said support means defining microvessels which individually open toward one of said first and second major surfaces,
- a plurality of the microvessels opening toward said first major surface of said support means to form a predetermined, ordered array,
- a plurality of said filters being located in separate interlaid sets of microvessels forming said planar array to form an interlaid pattern, and
- said support means providing a lateral barrier between adjacent microvessels.
In an element comprising a support means having first and second major surfaces and, on said support means, at least three laterally offset segmented filters,
- the improvement comprising:
- said support means defining microvessels which individually open toward one of said first and second major surfaces,
- a plurality of the microvessels opening toward said first major surface of said support means to form a planar array,
- next adjacent of the microvessels forming the planar array being laterally spaced by less than the width of adjacent microvessels opening toward either of said first and second major surfaces, and
- said filters being present at least in part in a plurality of the microvessels of said planar array to form a recurring pattern.
An element comprising:
- support means having first and second major surfaces, said support means defining a planar array of microvessels which open toward said first major surface,
- a segmented blue filter located in a first set of the microvessels,
- a segmented green filter located in a second set of the microvessels,
- a segmented red filter located in a third set of the microvessels,
- the first, second and third sets of the microvessels forming an interlaid pattern of blue, green and red filter segments, and
- said support means providing a lateral barrier between adjacent microvessels.
