epoxides using tetrabutylammonium bromide as a nucleophile source. Mechanistic considerations were inferred from electronic spectra and spectrophotometric titrations, showing that there are a series of equilibriums involved in the formation of the catalytic active species. Stability constants for the proposed equilibrium models were determined using SQUAD software. A catalytic cycle has been proposed

A novel polyimide resin is formed by imidizing a diamine component including an amide group-containing siloxane diamine compound represented by the following formula (1) and an acid dianhydride component including an aromatic acid dianhydride such as 3,3′,4,4′-diphenylsulfone tetracarboxylic dianhydride. This novel polyimide resin utilizes a novel polyimide resin into which a reaction group capable of reacting with a crosslinking agent to form a crosslinking point is pre-introduced before imidization. The novel polyimide resin can confer a comparatively low elastic modulus and heat resistance to a dry film or a photosensitive cover film formed from a photosensitive polyimide resin composition containing the novel polyimide resin.
In the formula (1), R
1
and R
2
are each independently an optionally-substituted alkylene group, m denotes an integer of 1 to 30, and n denotes an integer of 0 to 20.
