Claim:
A silsesquioxane resin wherein comprising the units (Ph(CH 2 ) r SiO (3−x)/2 (OR″) x ) m (HSiO (3−x)/2 (OR″) x ) n (MeSiO (3−x)/2 (OR″) x ) o (RSiO (3−x)/2 (OR″) x ) p (R 1 SiO (3−x)/2 (OR″) x ) q where Ph is a phenyl group, Me is a methyl group; R″ is hydrogen atom or a hydrocarbon group having from 1 to 4 carbon atoms; R is selected from a hydroxyl producing group; and R 1 is selected from substituted phenyl groups, ester groups, polyether groups; mercapto groups, aryl sulphonic ester groups, carboxylic acid containing groups, and reactive or curable organic functional groups; and r has a value of 0, 1, 2, 3, or 4; x has a value of 0, 1 or 2; wherein in the resin m has a value of greater than 0 to 0.95; n has a value of 0.05 to 0.95; o has a value of greater than 0.05 to 0.95; p has a value of 0.05 to 0.5; q has a value of greater than 0 to 0.5; and m+n+o+p+q≈1.
