The present invention provides an adhesive aid composition having excellent adhesive strength to polyimide films without decreasing mechanical properties and being useful in the field of electric materials. An adhesive aid composition of the present invention contains a phenolic hydroxyl group-containing polyamide and a solvent as essential components. The phenolic hydroxyl group-containing polyamide preferably has a segment represented by formula (1):
(wherein R1 represents a divalent aromatic group, and n represents an average number of substituents and is a positive number of 1 to 4). The adhesive aid composition of the present invention is suitably used for bonding polyimide films.

Provided is a thermosetting resin composition containing a polyimide compound (A) having a structural unit derived from a maleimide compound (a1) having at least two N-substituted maleimide groups and a structural unit derived from a diamine compound (a2); a modified polybutadiene (B); and an inorganic filler (C).
The four-electron reduction of CO2 in the presence of secondary aromatic amines is described for the first time to access aminals. Under metal-free hydrosilylation conditions, the four C-O bonds of CO2 are cleaved, and the organocatalysts are able to balance the reactivity of CO2 to promote the selective formation of two C-N and two C-H bonds. The methodology enables the formation of various symmetrical and unsymmetrical aminals.
