Abstract: The present invention provides a binder for a nonaqueous secondary battery electrode capable of greatly improving the peeling strength of an electrode active material layer to a current collector while suppressing the occurrence of cracks in the electrode active material layer formed on the current collector. The binder for a nonaqueous secondary battery electrode includes a copolymer (P) having a structural unit (a) derived from a monomer (A) represented by formula (1), a structural unit (b) derived from a monomer (B) which is at least one kind selected from the group consisting of a (meth)acrylic acid and a salt thereof, and a structural unit (c) derived from a monomer (C) which is an ethylenically unsaturated carboxylic acid ester of an aromatic alcohol.

Abstract: The present invention relates to a curable heat radiation composition which includes two types of fillers with different compressive breaking strengths (except when the two types of fillers are the same substance) and a thermosetting resin, the compressive breaking strength ratio of the two types of fillers [compressive breaking strength of a filler (A) with a higher compressive breaking strength/compressive breaking strength of a filler (B) with a lower compressive breaking strength] being 5 to 1,500, the compressive breaking strength of the filler (A) being 100 to 1,500 MPa, and the compressive breaking strength of the filler (B) being 1.0 to 20 MPa, an adhesive sheet using the composition and a method for producing the same. An aluminum nitride is preferable as the filler (A) and hexagonal boron nitride agglomerated particles are preferable as the filler (B).
