Abstract

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.
