What is claimed is: 1. A method of using a thick film getter composition comprising providing a thick film getter composition consisting of: (a) desiccant material selected from the group consisting of zeolites, metal sulfates, metal chlorides, metal bromides, and mixtures thereof dispersed in (b) organic medium consisting of (1) curable organic polymeric binder; (2) monomer; and (3) photoinitiator selected from the group consisting of unsubstituted polynuclear quinones, substituted polynuclear quinones, vicinal ketaldonyl alcohols, alpha-hydrocarbon-substituted aromatic acyloins, phenazine dyes, oxazine dyes, quinine dyes, Michler's ketone, benzophenone and 2,4,5-triphenlimidazlyl dimers having hydrogen donor, wherein the weight percent of the desiccant ranges from 10 to 65 percent of the total composition and the weight percent of the organic medium ranges from 35 to 90 percent of the total composition, wherein the thick film getter composition has been processed at a time and energy sufficient to facilitate photopholymerization of said monomer to control moisture. 2. The method of claim 1 comprising controlling moisture in a moisture sensitive electronic device. 3. The method of claim 2 wherein the desiccant material comprises 10-65 weight percent of the total composition. 4. The method of claim 1, wherein the composition is capable of controlling humidity levels to below about 1000 ppm. 5. The method of claim 1, wherein the composition is capable of allowing quick processing speeds, of about 5 seconds. 6. The method of claim 3, wherein the composition is capable of allowing quick processing speeds, of about 5 seconds, and low processing temperatures.
