    摘要: A novel class of interpenetrating polymer networks which are dispersible in conventional coating solvents is disclosed. Such dispersions are useful in preparing protective and/or decorative film coatings and are particularly useful in photosensitive or imaging formulations such as photoresists, solder masks and the like. These polymer networks are comprised of at least two interpenetrating crosslinked polymers. At least one of the polymer networks is formed by polymerization in a solvent. In one embodiment of this invention, at least one polymer network is prepared from macromers to produce a polymer system having functionalized branch or graft linear segments. The solvent dispersible interpenetrating networks of this invention are particularly useful as binders in addition polymerizable photosensitive compositions containing crosslinking monomers such as solder masks. Upon exposure to actinic radiation and suitable thermal curing, solder mask coatings of such photosensitive compositions form multiple, e.g., triple, interpenetrating polymer networks having superior toughness and flexibility.

    摘要: A photoresist composition having: (A) a polymer selected from the group consisting of: (a) a fluorine-containing copolymer having a repeat unit derived from at least one ethylenically unsaturated compound characterized in that at least one ethylenically unsaturated compound is polycyclic; (b) a branched polymer containing protected acid groups, said polymer comprising one or more branch segment(s) chemically linked along a linear backbone segment; (c) fluoropolymers having at least one fluoroalcohol group having the structure: —C(Rf)(Rf′)OH, wherein Rf and Rf′ are the same or different fluoroalkyl groups of from 1 to about 10 carbon atoms or taken together are (CF2)n wherein n is 2 to 10; (d) amorphous vinyl homopolymers of perfluoro(2,2-dimethyl-1,3-dioxole) or CX2═CY2 where X═F or CF3 and Y═—H or amorphous vinyl copolymers of perfluoro(2,2-dimethyl-1,3-dioxole) and CX2═CY2; and (e) nitrile/fluoroalcohol-containing polymers prepared from substituted or unsubstituted vinyl ethers; (B) at least one photoactive component; and (C) a functional compound selected from the group consisting of a base and a surfactant. The polymer may have an absorption coefficient of less than about 5.0m?−1 at a wavelength of about 157 nm. These photoresist compositions have improved imaging properties.
