Title:
PHOTOBASE GENERATOR, COMPOUND, PHOTOREACTIVE COMPOSITION, AND REACTION PRODUCT
Document Type and Number:
WIPO Patent Application WO/2021/049564
Kind Code:
A1
Abstract:
This photobase generator comprises a compound having: first skeletons represented by general formula (a); and a second skeleton having nitrogen atoms that are bonded to bonding positions of the first skeletons to form amide groups, wherein, in one molecule, the number of the first skeletons is at least two and the number of the nitrogen atoms forming the amide groups in the second skeleton is the same as the number of the first skeletons, and at least one of the nitrogen atoms forming the amide groups is converted to a nitrogen atom forming a secondary amine or a tertiary amine through light irradiation. In general formula (a), G is a divalent aromatic group, and * represents a bonding position to a nitrogen atom.
