1. An organic-inorganic composite resin, derived from:
(A) an inorganic portion comprising (a1) one or more siloxane monomers of formula (R1)nSi(OR2)4-n, wherein R1 is independently H, phenyl, C1-6 alkyl or a monovalent organic group with an end group selected from the group consisting of amino group, epoxy group, vinyl group, isocyanate group, mercapto group or (meth)acryloxy group; R2 is C1-3 alkyl; and n is an integer from 0 to 3; (a2) an acidic catalyst; (a3) silica; and (a4) a siloxane oligomer; and (B) an organic portion comprising (b1) one ore more acrylic monomers; wherein the weight ratio of the inorganic portion to the organic portion ranges from 2:8 to 8:2.
