摘要:
The invention provides poly(3-mono- and 3,5-disubstituted-4-acetoxy- and 4-hydroxystyrenes) and copolymers therefrom having a molecular weight in the range of from about 1,000 to about 800,000 wherein said 3-mono and 3,5-substitution is independently C₁ to C₁₀ alkyl or alkoxy, primary or secondary amino, halogen (Br, Cl, I), NO₂ or SO₃H. The polymers are used as a binder resin in photosensitive compositions, wherein the light-sensitive compound is an o-quinone diazide or as an acid-forming radiation-sensitive compound in combination with a compound cleavable by acid.
