Compositions for antireflective coatings

A composition comprising at least the following:

• A) a cure catalyst selected from Formula A:
• [NR1′R2′R3′R4′]+X− (Formula A),
• R1′, R2′, R3′, R4′ are each independently selected from hydrogen, alkyl (linear or branched), substituted alkyl, aryl, or substituted aryl;
• X is a monovalent anion, and
• wherein in Formula A, at least one of R1′, R2′, R3′ or R4′ is a methyl;
• and
• B) a prepolymer formed from a first composition comprising the following:
• a) a Compound F1 selected from Formula 1:
• wherein Ra comprises one or more multiple bonds, provided that, if Ra comprises more than one multiple bond, these multiple bonds are not in a conjugated configuration;
• and
• R1, R2, and R3 are each independently selected from alkoxyl, hydroxyl, halide, OC(O)R, or OC(O)OR, wherein R is alkyl or a substituted alkyl;
• b) a Compound F2 selected from Formula 2:
• wherein Rb is selected from H or a saturated group comprising alkyl, alkylene, or alkylidene;
• and R4, R5, and R6 are each independently selected from alkoxyl, hydroxyl, halide, OC(O)R, or OC(O)OR, wherein R is alkyl or a substituted alkyl;
• c) a Compound F3 selected from Formula 3:
• wherein Rc comprises more than one multiple bond, and these multiple bonds are in a conjugated configuration;
• and R7, R8, and R9 are each independently selected from alkoxyl, hydroxyl, halide, OC(O)R, or OC(O)OR, wherein R is alkyl or a substituted alkyl;
• and
• d) a Compound F4 selected from Formula 4:
• wherein R10, R11, R12, and R13 are each independently selected from alkoxyl, hydroxyl, halide, OC(O)R, or OC(O)OR, wherein R is alkyl or a substituted alkyl;
• and
• wherein the molar ratio of F1/F4 is from 1/20 to 1/1;
• and
• wherein Compound F1 is present in an amount from 5 to 50 weight percent;
• Compound F2 is present in an amount from 5 to 50 weight percent;
• Compound F3 is present in an amount from 2 to 20 weight percent;
• and Compound F4 is present in an amount from 20 to 80 weight percent;
• and wherein each weight percentage is based on the weight of the first composition.
