Claim:
A composition comprising: (I) a silsesquioxane resin comprising HSiO 3/2 units and RSiO 3/2 units where R is an acid dissociable group having the formula wherein each R 3 is independently a linking group; R 4 is a second linking group; L is selected from the group consisting of linear or branch alkylene groups having 1 to 10 carbon atoms, fluoroalkylene groups having 2 to 20 carbon atoms, substituted and unsubstituted arylene groups, substituted and unsubstituted cycloalkylene groups, and substituted and unsubstituted alkarylene groups; R 5 is hydrogen, linear or branched alkyl or fluoroalkyl; R 6 is alkyl or fluoroalkyl; Z is an acid-cleavable group; f is 0 or 1; g is 0 or 1; h is 0 or 1; and (II) an organic base selected from 2-(2-amino-phenyl)-isoindole-1,3-dione, 1-(2-((1H-1,2,3-benzotriazol-1-ylmethyl)amino)phenyl)ethanone, N-benzyl-N-ethylaniline, 1-((2,3-dimethyl-phenylamino)-methyl)-pyrroilidine-2,5-dione, 1-(2-methyl-4-phenylamino-3,4-dihydro-2H-quinolin-1-yl)-heptan-1-one and 2-((3-fluoro-4-methyl-phenylamino)-methyl)-phenol.
