Document Type and Number:
Japanese Patent JP4053603
Kind Code:
B2
Abstract:
The present invention provides a novel soluble polyimide resin which is superior in solubility in solvents and transparency, which is useful particularly in electronics and optronics fields, and which has good processability; a process for production of the resin; and a solution composition of the resin. A soluble polyimide resin containing, as part or the whole of the diamine units, a 2,5(or 6)-bis(aminomethy l)bicycloÄ2.2.1Üheptane and having a light transmittance of 60% or more in a range of wavelength larger than 400 nm in an ultraviolet-visible light spectrum measured for a film of 10- mu m thickness; a process for production of the resin; and a solution composition of the resin.
