An alkali-developable photosensitive color composition containing a binder resin, a fluorine-containing copolymer, a photopolymerization initiator, a colorant, and a solvent. A photopolymerizable unsaturated compound is used as the binder resin. The photopolymerizable unsaturated compound is obtained by adding (B) an unsaturated monobasic acid to (A) a polyfunctional epoxy resin to form (C) an epoxy adduct and allowing the epoxy adduct (C) and (D) a polybasic acid anhydride to react with each other.

Alkali-developable photosensitive color composition

Disclosed are surfactants represented by the following formula (1):wherein Rrepresents a branched aliphatic hydrocarbon group, a secondary aliphatic hydrocarbon group or a branched aliphatic acyl group, AO and AO' each independently represents an oxyalkylene group having 2 to 4 carbon atoms, L represents a group represented by formula (2) to be described below, z stands for a number of from 1 to 10, X represents a hydrogen atom or an ionic hydrophilic group, m stands for a number of from 0 to 1,000, and n stands for a number of from 0 to 1,000.wherein Rand Reach independently represents a hydrogen atom or a methyl group, x stands for a number of from 0 to 12, and y stands for a number of 0 or 1. These surfactants do not contain any phenyl ether group considered to have significant effects on the environment, such as a nonylphenyl group, and have performance comparable with reactive surfactants containing one or more phenyl ether groups. Emulsifiers for emulsion polymerization, dispersants for dispersion polymerization and resin modifiers, all of which contain the surfactants, are also disclosed.

An improved solution polymerization process is provided wherein vinyl monomers are polymerized in the presence of at least one reactive modifier which is a substituted alpha-olefin that incorporates at least three ether groups, is hydrophilic, and has a molecular weight of at least about 200. The modified vinyl polymers so produced are characterized by various improved physical properties including, in particular, electrical characteristics such as antistatic capacity.
