A self-contained photohardenable imaging assembly comprising in order: a first transparent support; an imaging layer comprising a developer material and a plurality of photohardenable microcapsules encapsulating a color precursor, and a second support, wherein at least one support comprises a barrier layer that exhibits a low water vapor transmission rate. The imaging assembly has been found to provide better image quality and more consistence sensitometric response to pressure development.

1. A self-contained imaging assembly comprises in order:a first transparent support that is 10 to 250 micron in thickness and has a light transmission of at least about 80% at a wavelength at 550 nm, wherein the first support comprises a barrier layer made from a material that is selected from the group consisting of fluorinated polymers, inorganic oxides, and inorganic nitrides; one or more imaging layer comprising a plurality of photohardenable microcapsules encapsulating a color precursor which can react with a developer material in the same or an adjacent imaging layer; a second support which may be opaque or transparent wherein the second support comprises a barrier layer made from a material that is selected from the group consisting of fluorinated polymers, inorganic oxides, inorganic nitrides, and aluminum metal; wherein the imaging layer has a moisture content substantially the same as when preconditioned to a relative humidity of at least about 50 percent; and wherein both the first support and the second support has a water vapor transmission rate of less than 0.77 g/m2/day (0.05 g/100 in2/day).
