A siloxane resin having the formula: (HSiO<SUB>3/2</SUB>)<SUB>a</SUB>(RSiO<SUB>3/2</SUB>)<SUB>b</SUB>(SiO<SUB>4/2</SUB>)<SUB>c</SUB> where R is Z, Z(CH<SUB>2</SUB>)<SUB>n</SUB> or ZO(CH<SUB>2</SUB>)<SUB>n</SUB> where Z is a phenyl or substituted phenyl group; n has a value of 1 to 6, a has value of 0.01 to 0.7, b has a value of 0.05 to 0.7, c has a value of 0.1 to 0.9 and a + b + c ~ 1. The siloxane resins are useful in anti-reflective coating compositions. |
