A photosensitive composition, an article comprising the composition and the use of the composition as a photoresist.

摘要

The properties of a dichromated hydrophilic colloid photosensitive composition are improved by the incorporation of certain copolymer latices. More particularly, the copolymer particles in the latex have from 75 to 95 percent by weight of at least one repeating unit conforming to the structure:
and from 5 to 25 percent by weight of at least one repeating unit conforming tothe structure:
wherein:
R¹ is hydrogen or methyl;R² is phenyl, substituted phenyl or a straight- or branched-chain alkoxycarbonyl group having 2 to 8 carbon atoms;R³ is hydrogen or methyl;R' is -NR⁵R⁶ or -OR' wherein R⁵ and R⁶ are independently selected from hydrogen, alkyl or substituted alkyl having 1 to 8 carbon atoms and alkyl containing one or more hetero atoms in the alkyl chain, and R' is hydroxyalkyl having 1 to 8 carbon atoms. The photosensitive composition may be used as a photoresist in preparing filter arrays for solid state color imaging devices.
