WIPO Patent Application WO/2017/221776
Kind Code:
A1
Abstract:
Provided is a polyimide resin which is mainly composed of a structural unit of formula 1, while containing a structural unit of formula 2 in an amount of 2-30 mol% of the total structural units, and which has excellent light transmission properties, low birefringence, low linear thermal expansion properties, and laser releasability.
In the formulae, R1 represents a group having 4-40 carbon atoms (a monocyclic/condensed polycyclic alicyclic group or a group wherein monocyclic/alicyclic groups are linked to each other directly or via a crosslinked structure); R2 represents a group of formula 3; R3 represents a group of formula 4 or a group of formula 5; each of R4-R11 represents a hydrogen atom, a halogen atom, a halogen-substituted group having 1-3 carbon atoms; and X1 represents a bond, an oxygen atom, a sulfur atom, a sulfonyl group, a halogen-substituted group having 1-3 carbon atoms, an ester bond, an amide bond or a sulfide bond.
